Last updated October 20, 2026. Prices, free-tier limits and privacy terms were checked against each vendor's own pages that day. By Dan Fitzpatrick.
Pick by bottleneck. Gemini Notebook suits explaining concepts from your own course materials, MagicSchool suits building resources, SchoolAI suits guided student practice, and Graded Pro and Snorkl suit grading: Graded Pro for handwritten work against a mark scheme, Snorkl for students' spoken and drawn reasoning. None of them replaces your judgment on lab safety, extended answers or a final grade.
Which AI tool fits which science teaching job?
The table puts all five side by side. Prices and limits come from each vendor's page, checked October 20, 2026. Privacy entries repeat what the vendor says, not what we have verified.
| Tool | Best use | Strengths | Limitations | Price / free tier | Privacy considerations |
|---|---|---|---|---|---|
| Gemini Notebook | Explaining concepts and building revision material from your own sources | Answers drawn from files you upload, with inline citations (directory feature list) | Only as good as the sources you give it; no grading | Directory lists freemium; Google's July 16, 2026 rename post states no price | Google says Education data is not human reviewed or used to train models; K-12 admins must turn it on |
| MagicSchool | Handouts, quizzes and leveled texts | 80+ teacher tools on the free plan | Student tools need Plus; science content needs your check | Free $0; Plus $8.33/user/month billed annually or $12.99 monthly | Vendor lists FERPA, COPPA and SOC 2 claims; the custom data privacy agreement is an Enterprise feature |
| SchoolAI | Guided student practice you can watch | Teacher-set guardrails and live monitoring of student chats (directory feature list) | Free trial caps you at 5 Space launches a year | Free Trial, then Pro and Scale with no public prices | Vendor says FERPA and COPPA compliant; the free trial uses a standard agreement accepted in the terms |
| Graded Pro | Grading handwritten STEM work against your mark scheme | Reads handwriting, equations and diagrams; you review before release | Credit-based; accuracy figures are the vendor's own | Teacher Free $0 (150 credits at signup, up to 50 a month); Teacher Pro $25 for 6,000 credits | Vendor says aligned with FERPA, COPPA and GDPR; its page does not say where work is stored or whether it trains models |
| Snorkl | Seeing how students reason, by voice, drawing or text | Instant feedback plus misconception analytics (directory feature list) | Free plan limits activities; no grading against a mark scheme | Free for teachers; Premium by quote | Both plans list a data privacy agreement; the pricing page does not mention FERPA or COPPA |
Gemini Notebook is the best fit for explaining concepts from your own course materials
Gemini Notebook is the new name for NotebookLM. Google announced the change on July 16, 2026 and described it as still a standalone app, now reachable from the Gemini app too. Upload your unit plan, the textbook chapter and the exam board's examiner reports, and ask it where students lose marks on a topic. Because answers come from those files, you can click through to the passage and check it.
Watch out for: a notebook can only repeat what you put in it. If the source has an error, so will the summary.
Pricing: the rename post does not say whether the standalone app is free, so we have no verified price. The directory lists it as freemium.
Safety: for Workspace for Education accounts, Google says uploads, queries and responses are not reviewed by human reviewers and are not used to train AI models. Its April 2025 announcement made NotebookLM a core service for education customers, said admins of K-12 domains must turn access on, and set the age at 18 and older. Google's current help page says Workspace for Education users can access it at all ages, so the two pages differ. Ask your administrator which applies to students in your district.
MagicSchool is the best fit for handouts, quizzes and leveled texts
MagicSchool is a broad toolbox, so it suits a teacher who wants a first draft of a lab handout, a quiz or a reading rewritten for a lower reading level without writing a prompt. The Free plan includes 80+ teacher tools, quizzes and Class Writing Feedback.
Watch out for: a generated explanation of a science concept reads fluently whether or not it is right. Check every claim, equation and unit before it reaches students.
Pricing: Free is $0. Plus is $8.33 per user per month billed annually, or $12.99 billed monthly, and adds unlimited generations and the 50+ student tools. Enterprise is quoted.
Safety: the vendor lists FERPA, COPPA, SOC 2 and GDPR compliance on its pricing page. That is the vendor's claim. A custom data privacy agreement is listed only under Enterprise, so a school on Free or Plus should find out what agreement covers it.
SchoolAI is the best fit for guided student practice you can watch
SchoolAI lets you build a "Space," a guided activity where students talk with an AI set up for one topic, such as explaining why ice floats. You set the guardrails and see the conversations as they happen. The directory lists it at 4.92 from 13 reviews.
Watch out for: the free trial allows 5 Space launches a year, which is five sessions for the whole school year. Student uploads, the notetaker and student portals are not in the trial.
Pricing: three tiers, Free Trial, Pro and Scale. The page shows no dollar amounts for the paid tiers.
Safety: the vendor says the platform is FERPA and COPPA compliant. The free trial uses a standard data privacy agreement accepted in the terms of service when an account is created. Pro and Scale use a district-wide agreement. The page does not give a student age range.
Graded Pro is the best fit for grading handwritten work against your mark scheme
Graded Pro now sits on a site called Grade Direct, from EDSYSTEMS LTD; the address in the directory, graded.pro, redirects there. The vendor's page says it reads handwriting, equations, diagrams and code, and that teachers can preview and edit feedback before it goes back. Sample grading examples on the page include biology, chemistry and physics.
Watch out for: the vendor reports a 0.97 correlation with professional markers, 85% of marks identical to the examiner's and 96% within one mark. Those are the vendor's own figures, and the methodology sits in a separate accuracy report we did not review. The same page says teachers can use it for "less than $10 per month" while listing Teacher Pro at $25, so check the current price at signup.
Pricing: Teacher Free is $0 with 150 credits at signup and up to 50 more a month. Teacher Pro is $25 for 6,000 credits that do not expire. The page says a basic task costs about 3 credits, an in-depth task 8 to 10, and a full exam about 30. At those rates the free 50 credits a month cover roughly one full exam, or about 16 basic tasks.
Safety: the vendor says the platform is aligned with FERPA, COPPA and GDPR. Its page does not say where student work is stored, how long it is kept or whether it trains models. The directory lists UK hosting and a minimum age of 4. Read the linked privacy pages before you upload scripts with names on them.
Snorkl is the best fit for seeing how students reason
Snorkl has students record a voice explanation over a whiteboard drawing, then returns AI feedback against criteria you set. For a subject built on misconceptions, a recorded explanation shows where the model in a student's head breaks, which a right-or-wrong answer hides.
Watch out for: it gives feedback on reasoning, not a mark against an exam mark scheme, so pair it with a grading tool if you need scores.
Pricing: the plans page lists a Free plan for teachers with unlimited classes but limited activities, and a Premium plan for schools and districts by quote. No prices are shown.
Safety: both plans list a data privacy agreement and single sign-on. The page does not mention FERPA or COPPA and states no age requirement. Ask Snorkl for its privacy policy and your district's approval status before students record their voices.
Four questions that choose the tool
- Where does your week go? Explaining concepts points to Gemini Notebook. Preparing handouts and quizzes points to MagicSchool. Watching students practice points to SchoolAI. Grading points to Graded Pro. Hearing student reasoning points to Snorkl.
- Will student data touch the tool? If only you use it with your own materials, the risk is smaller. If students log in, or you upload scripts with names on them, check the age minimum, the data agreement and whether your district has approved the tool.
- Is the output a draft or a grade? Drafts get a read-through. Grades that count toward a report need your own marks on a sample first.
- Can you check the answer quickly? In science you usually can, which is why these tools suit you better than most subjects. Use that advantage instead of trusting the output.
What does a lesson built with these tools look like?
This is a plan, not a report from a classroom. Take a grade 10 chemistry lesson on limiting reactants, with a claim-evidence-reasoning exit ticket (a GCSE class would use a six-mark question instead).
- Plan: upload the unit outline and last year's examiner comments to Gemini Notebook. Ask which two errors students make most on limiting-reactant questions, and open the cited passages to confirm both.
- Prepare: have MagicSchool draft a one-page worked example at two reading levels. Check every number yourself.
- Practice: students explain one calculation aloud on a Snorkl whiteboard, or you set a SchoolAI Space where the AI asks guiding questions and you watch the conversations.
- Grade: scan the exit tickets into Graded Pro with a mark scheme you wrote. Mark ten scripts yourself first, compare, and release feedback only after you review each mark.

How accurate is AI grading of science answers?
It depends on the task, which is why the ten-script check matters. One preprint from January 2025, by Yang, Latif, He and Zhai, tested a fine-tuned ChatGPT model on 7,626 written scientific explanations from 1,593 grade 8 to 12 students in Beijing. Agreement with human scoring ran from 80% to 94% on the holistic score, depending on the question. The responses were in Chinese, the model was fine-tuned for the study, handwritten answers were transcribed, and the paper is not yet peer reviewed, so it shows that accuracy varies by item, not what any tool in this article will do on your questions.
How much time can it save?
Less than the headline suggests, and unevenly. In the Walton Family Foundation and Gallup Teaching for Tomorrow study, published June 24, 2025, 2,232 US public K-12 teachers were surveyed from March 18 to April 11, 2025. Teachers who used AI weekly estimated they saved 5.9 hours a week, about six weeks a school year. The figure is self-reported, covers all teaching tasks, and is not specific to science. Our view is that grading and resource drafting are where a science teacher is most likely to see it.
