For most history teachers the answer is not one tool but three jobs. Use Diffit to turn a single primary source into a readable class set at several reading levels, Gemini Notebook, formerly NotebookLM, to ask questions of a document set and get answers that cite the documents rather than the open web, and Brisk Teaching to leave feedback on essay drafts inside the Google Doc the student already wrote them in. All three have a free tier for individual teachers, checked September 25, 2026. If you only have time to try one this semester, make it Diffit, because source adaptation is the job that eats the most preparation time and the one the rest of the lesson depends on.
Below are seven tools, each matched to a job a history or social studies teacher actually has, with what each one is bad at, what it costs, and what you still have to check with your own district before students touch it.
Which AI is best for history, in one line each
| Tool | Best use | Strengths | Limitations | Price / free tier (checked Sep 2026) | Privacy considerations |
|---|---|---|---|---|---|
| Diffit | Re-leveling a primary source for a mixed class | Paste a source or URL, get leveled versions plus vocabulary and questions | Free plan only reaches resources from the last 90 days | Free basic; $14.99/month or $149.99/year individual; schools quote-only (pricing) | Directory record blank on FERPA, COPPA, hosting and age; teacher-facing use keeps students off the platform |
| MagicSchool | The widest set of ready-made teacher generators | 80+ teacher tools on the free tier | Generic across subjects; nothing built for document analysis | Free forever; Plus $8.33/user/month annually or $12.99 monthly; Enterprise custom (pricing) | Custom data agreement, SSO and LMS integration sit on Enterprise only |
| Brisk Teaching | Feedback on drafts where the writing already lives | Works on any webpage or Google Doc; unlimited usage free | Free plan caps batch feedback uploads | Free for teachers; school and district tiers quote-only (plans) | Directory record blank on FERPA, COPPA, hosting and age |
| Gemini Notebook | Answers grounded in your documents, not the web | Cites the source passage for every claim it makes | Will not reach beyond what you upload, which is the point | Free tier; school access depends on your Workspace edition (support) | Education editions state uploads and outputs are not human-reviewed or used to improve models |
| SchoolAI | Supervised student debate and interpretation | Teacher can read every student conversation | Free tier allows 5 Space launches a year | Free tier; Pro and Scale quote-only (pricing) | States FERPA, COPPA and SOC 2 Type 2 compliance; free users get a standard DPA through the terms of service |
| Class Companion | Repeated written practice at AP scale | Instant feedback on short answers, outlines and essays against AP requirements | Publishes no scoring accuracy data | Free plan for individual teachers; school plan no public pricing (site) | Directory record is unreliable (see note below); check the vendor directly |
| Curipod | Turning a source into a live writing task | Weekly writing sessions free, unlimited student writers | Student responses capped at 1,000 characters on free | Free; school and district custom (pricing) | Records student responses, so it deserves a district check first |
The three questions that pick the tool for you
Before you look at a single feature list, answer these three. They resolve almost every choice on this page.
1. Does the source already exist somewhere, or do you need to build the resource? If you have the document and need it readable by everyone in the room, that is Diffit or Brisk. If you need the inquiry question, the timeline and the retrieval starter built from nothing, that is MagicSchool.
2. Do students touch the tool, or only you? Teacher-facing tools keep student data out of the question entirely. The moment students log in and type, you have a district conversation on your hands, and the tools below split cleanly on this line.
3. Does the answer need to be traceable to a document? General chatbots produce fluent history that is sometimes invented. If a student will cite it, you want a tool that shows you which passage the claim came from, which is the single strongest argument for Gemini Notebook in this subject.
What the tools directory says about history, and what it leaves out
Here is something worth knowing before you shop. Of the 138 tools listed in the AI Educator Tools directory as of September 25, 2026, 42 name History among their subject areas. Not one of those 138 records mentions "primary source", "document-based question", "source analysis" or "social studies" anywhere in its description or feature list. Six mention reading-level adaptation.
So the market has built plenty of general teaching tools and then tagged them for history. It has built almost nothing for the job that defines the subject. That is why the recommendations below are organized by job rather than by product: you are assembling a workflow out of general tools, and knowing which general tool does which history job well is most of the skill.
Diffit: the fastest way to turn one source into a class set
Diffit is the best fit for re-leveling primary sources because it is the only tool here whose core function is exactly that job, and it holds a 4.20 out of 5 rating from 5 reviews in the directory. Paste a document, a URL or a topic, and it returns the text rewritten at several reading levels along with vocabulary, summaries and comprehension questions. A class reading the Gettysburg Address can work from the same document at four entry points instead of four different worksheets.
The discipline point matters more here than anywhere else on this page. Abridging a source changes it. A rewritten Declaration of Independence at a fourth grade reading level is no longer a primary source; it is a paraphrase of one. Use the leveled versions as a ramp toward the original, keep the original in front of students, and say out loud which one they are reading.
Watch out for: on the free plan you can only reach resources you made in the last 90 days, so anything you build for a unit you teach annually is gone by the time you teach it again unless you export it.
Pricing: the basic plan is free and includes downloading to PDF, printing, sharing and editing, with access limited to the last 90 days of content. An individual teacher subscription is $14.99 a month or $149.99 a year and adds export to Google Docs, Slides, Forms and Classroom, standards alignment and access to everything you have ever made (Diffit pricing, individual subscription, checked September 25, 2026). Diffit for Schools is a flat annual rate tiered by enrollment with no published figure.
Safety: Diffit's directory record is blank on FERPA, COPPA, data hosting and minimum age, so we are not going to guess. Used the way most history teachers use it, as a teacher tool that produces printables, students never create an account and no student data enters the platform. If you plan to have students log in, that is the point at which you need your district's data agreement in hand.
MagicSchool: the broadest set of generators, none of them built for history
MagicSchool is the best fit for building the scaffolding around an inquiry because it ships more ready-made teacher generators than anything else here, 80 or more on the free tier, and it carries a 4.74 out of 5 rating from 19 directory reviews. Text leveler, rubric generator, DOK question generator, unit plan, exit ticket. For the parts of a history unit that are not the source work, it is the quickest route from blank page to first draft.
Our view is that MagicSchool is a breadth tool, not a history tool. Nothing in it is designed around document analysis, and its output on historical causation tends toward the generic. Generate the structure, then put your own subject knowledge into it. That is the deal with every tool on this page and it is most obviously true of this one.
Watch out for: the free tier limits generations and output history. If you build a whole unit in one sitting you will hit the ceiling.
Pricing: free forever with 80+ teacher tools. Plus is $8.33 per user per month billed annually or $12.99 billed monthly, and adds unlimited generations, unlimited output history and 50+ student tools. Enterprise is custom (MagicSchool pricing, checked September 25, 2026).
Safety: MagicSchool states on its pricing page that a custom data privacy agreement, single sign-on and SIS or LMS integration are available on the Enterprise tier only. A vendor's own compliance statement is not your district's sign-off, and the free tier you are likely to start on is not the tier carrying the custom agreement. If students will use the student tools, that distinction is the one to raise with your technology director.
Brisk Teaching: feedback where the writing already is
Brisk Teaching is the best fit for responding to essay drafts because it runs as a browser extension on top of Google Docs and any webpage, so neither you nor the student moves the work anywhere, and it holds the highest review count of any tool here at 4.77 out of 5 from 35 directory reviews. Open a student's document, ask for targeted feedback, and the comments land in the document. On a webpage holding a source you want to use, it will change the reading level in place.
For history the useful pairing is its feedback on structure and use of evidence. An essay that has the history right and the paragraph shape wrong is the most common thing in a stack of drafts, and that is the failure a model diagnoses reliably. The judgment about whether the argument is any good stays with you.
Watch out for: the free plan caps how many documents you can upload for batch feedback, so a class set of 30 in one go is a paid-tier action.
Pricing: free for teachers, with 20+ tools, unlimited usage, standard language models, glow and grow feedback and Brisk Boost for students. Premium for schools and Intelligence for districts are both custom-priced with no public figure, and add 35+ tools, faster models and no upload limit (Brisk plans, checked September 25, 2026).
Safety: Brisk's directory record is blank on FERPA, COPPA, hosting and minimum age. Because the extension reads the document you have open, the practical question for your district is not the vendor's badge but what it can see when a teacher installs it on a managed account. Ask your technology director to review the extension's permissions before a department-wide rollout.
Gemini Notebook: the answer that has to show you the document
Gemini Notebook is the best fit for research that must not invent anything because it answers only from sources you upload and shows the passage behind each claim, and it carries the largest review base in the directory for this group at 4.84 out of 5 from 90 reviews. Upload a set of documents on Reconstruction and ask what the sources disagree about; every sentence it returns comes with a citation you can click back to.
This is the tool that fixes the problem history teachers complain about most. The American Historical Association states in its guiding principles, approved July 2025, that generative AI "regularly hallucinates content, references, sources, and quotations" and that it introduces a false sense of certainty where uncertainty exists. A closed, cited source set is the structural answer to that, and it is also a teachable model: this is what it looks like when a claim is tied to evidence.
Watch out for: it will not reach past the documents you give it, which is the feature, but it means a thin source set produces thin answers. Curating the set is now the lesson preparation.
Pricing: there is a free tier. With a school Google account, access depends on your organization's Workspace edition, so it may already be switched on for you or may need an administrator (Google support, checked September 25, 2026).
Safety: Google's support page states that for standard accounts your data is not used to train the product unless you submit feedback, and that on education and enterprise editions uploaded files, chats and model outputs are not reviewed by humans or used to improve generative AI models. Which of those applies to you depends on your district's edition, and that is a question for your Workspace administrator rather than an assumption.
SchoolAI: student debate you can actually read
SchoolAI is the best fit for letting students argue with an AI about a historical question because the teacher can open any individual student's conversation and read it, and it holds the highest rating in this group at 4.92 out of 5 from 13 directory reviews. Launch a Space framed around an interpretation question, send students in, watch the transcripts.
Used well this is interpretation practice, not content delivery. Set the AI to defend a position the class has evidence against and the task becomes finding the evidence, which is the habit good history depends on.
Watch out for: the free tier allows only 5 Space launches a year, which is enough to evaluate the tool and not enough to teach with. Plan the trial around that number.
Pricing: SchoolAI publishes no dollar figures. The page shows a free tier, Pro and Scale, with the free tier limited to 5 Space launches a year and 10MB document uploads, and prices available on request (SchoolAI pricing, checked September 25, 2026). Treat this as quote-only.
Safety: SchoolAI's pricing page states the platform is FERPA, COPPA and SOC 2 Type 2 compliant and 1EdTech certified. It also states that free users accept a standard data processing agreement through the terms of service at sign-up, while district-wide or custom agreements sit on the paid tiers. That difference matters: a teacher signing up alone has accepted terms on behalf of students without the district reviewing them, which is exactly the situation most district policies are written to prevent. Check before you launch a Space with a real class.
Class Companion: written practice at the volume AP demands
Class Companion is the best fit for repeated written practice because it gives students instant feedback on outlines, short answers and essays against AP requirements, which is the only realistic way to raise the number of DBQs a student writes in a year. Its own site describes feedback that explains mistakes and lets students dispute the assessment, and it covers US History, World History, Psychology and other AP courses (Class Companion).
This matters more from May 2027, when the College Board's AP history exam changes take effect: students will answer all three short-answer questions rather than choosing, the long essay becomes a single required prompt, and the document-based question draws on evidence from across the whole course. More required writing, less choice, which means volume of practice matters more than it did.
Watch out for: the company publishes no data on how closely its scores match human AP readers, and its own site says teachers should evaluate student work individually and use the platform for support. Treat the score as a first pass a student revises against, not as a grade.
Pricing: no public pricing. Class Companion's site states there is a free plan for individual teachers and their students, and that the paid school or district plan adds LMS integration, insights and response integrity detection, with figures available on request (Class Companion, checked September 25, 2026).
Safety: the directory record for Class Companion is currently unreliable, carrying details that appear to belong to a different vendor, so we are not quoting it. Its minimum age, hosting location and compliance position should be confirmed with the company directly before students use it, and it does record student writing, so it needs a district review.
Curipod: turning a source into a live writing task
Curipod is the best fit for putting a source in front of a class as a live writing prompt because its free tier runs weekly writing sessions with unlimited student writers and instant feedback, and it carries a 4.67 out of 5 rating from 3 directory reviews. Drop in a source, set the question, and every student writes rather than the three who put their hands up.
Watch out for: on the free plan student responses are capped at 1,000 characters, which is roughly a paragraph. That suits a source-analysis warm-up and does not suit an essay.
Pricing: free at $0 a month with a set number of live sessions renewing weekly, unlimited student writers, standards alignment and limited social studies writing practice. The school and district plan is custom-priced and lifts responses to 5,000 characters and adds custom rubric scoring (Curipod pricing, checked September 25, 2026).
Safety: students type responses into the platform, so student work is recorded. The directory record is blank on FERPA, COPPA, hosting and age. This is one to put through your district's review rather than trial with a live class first.
A worked example: ninth grade world history, one source, 45 minutes
This is a plan to follow, not a report of a lesson that happened. The topic is the 1839 Letter of Lin Zexu to Queen Victoria, in a mixed ninth grade world history class with reading levels spanning roughly four grades.
Before the lesson, about 20 minutes of preparation. Put the full text of the letter into Diffit and generate three reading levels plus the vocabulary list. Print the original alongside the level closest to each group. In Gemini Notebook, upload the letter together with two secondary accounts of the Opium Wars, then ask what the sources disagree about; use the citations it returns to decide which two disagreements are worth the lesson and discard the rest.
First 10 minutes. Students read their leveled version. The original is on the desk next to it. Ask what one word in the original they could not have guessed from the adapted version, which puts the act of adaptation itself on the table.
Next 20 minutes. Students answer one question in writing: what does Lin Zexu assume about Britain's obligations, and what does that tell us about how he understood the relationship between the two states? Run it as a Curipod session so every student writes and you see the responses as they come in, keeping the answer inside the 1,000-character free-tier limit.
Last 15 minutes. Take two contrasting student answers, put them on the board, and have the class argue which is better supported by the letter itself. No AI in this part. The judgment is the lesson.
What to check afterward. Read three of the leveled versions against the original before you use them again. If a rewrite dropped the letter's tone of moral appeal, which is the heart of the document, that leveled version needs fixing or retiring.
What the big AI names are actually good for in a history class
Search assistants get asked about these constantly, so here is a straight answer on each.
ChatGPT is a strong drafting partner for you and a poor research tool for students on historical questions, because it produces confident prose with no traceable source behind it. Rated 4.35 out of 5 from 23 directory reviews.
Khanmigo is built around Socratic tutoring and covers humanities, so it suits a student who is stuck on understanding a period rather than one analyzing a document. Rated 4.40 out of 5 from 5 directory reviews.
Perplexity cites its sources as it answers, which makes it genuinely useful for teaching students to check where a claim came from, though the sources are the open web rather than documents you chose. Rated 4.27 out of 5 from 15 directory reviews.
Quizlet is not in the directory. It is a retrieval-practice tool, which is a real job in history, but it has nothing to do with source work and should not be confused with one that does.
Hello History, which offers conversations with AI versions of historical figures, is listed in the directory with no rating yet. Our view is to be careful: the AHA guidance specifically warns that AI can fabricate convincing historical scenarios that never occurred. A simulated Lincoln is a creative writing exercise, not evidence, and students need to be told which one they are doing.
What history's own professional bodies say
This is the part the general "AI for teachers" lists leave out, and it is the part that should shape your department's policy.
The American Historical Association approved guiding principles for AI in history education in July 2025. Its position is not a ban. It holds that bans are impractical, that AI literacy is now part of the discipline, and that syllabi should state explicitly when AI is permitted. What it rules out is submitting AI-written work as original, using AI summaries in place of reading the source, and including citations nobody checked.
In the same year, Tina Heafner and Daniel Maxwell published the CIVIC framework for AI in social studies education in the CITE Journal. Its most useful instruction for classroom practice is a sequencing one: students engage with primary sources before they use AI, and they validate AI output against the original documents rather than accepting the summary.
There is a reason both documents land on verification. Stanford's national study of students' civic online reasoning assessed 3,446 high school students across 14 states and found that 96.8% scored at the lowest level when asked to evaluate a website's reliability, and that two-thirds could not distinguish a news article from sponsored content. That was measured before generative AI was in any classroom. Whatever tool you pick, the evaluation skill is the curriculum, not the overhead.
How to actually choose
Start with the job that costs you the most time this term, not with the tool that looks most impressive. For most history teachers that is source adaptation, so start with Diffit and give it one unit. If your bottleneck is essay feedback instead, start with Brisk, because it works where your students already write. If it is your own preparation reading, start with Gemini Notebook.
Add a student-facing tool only after you have your district's answer on data, and only when the teacher-facing tools have already saved you the time. Tools where students log in and type carry a review process that teacher-facing tools do not, and there is no reason to spend that cost before you have proven the value.
If you want to see the field rather than these seven, the lesson planning and resource creation category holds the tools that build materials, and the assessment and grading category holds the ones that respond to student work. For the essay-feedback job specifically, our guide to AI writing feedback tools goes deeper than this page does, and if the worry is students submitting AI-written essays, AI-resistant assessment is the more useful read. Teachers working across a full high school timetable may also want the broader high school picks.
The bottom line
There is no best AI for history, and the question is slightly the wrong one. There is a best tool for making a source readable, a best tool for answering from documents rather than from the internet, and a best tool for responding to thirty drafts on a Sunday. Diffit, Gemini Notebook and Brisk cover those three, all have a free tier, and none of them requires a student account to be useful.
What none of them do is the history. Deciding which source is worth the lesson, noticing that a rewrite flattened an argument, judging whether a student's claim is actually supported: that work has not moved, and the tools are only worth having because they clear the time to do it.
