The best AI video makers for teachers in 2026
To turn lesson notes into short narrated videos that end with a question: Chasca. Kinoslide, Scholarly, Scrimba Explain and Gemini Notebook compared.
By the Chasca team 9 min read
The best AI video maker for a teacher depends on what the video has to do for your class. To turn lesson notes, a photo of a worksheet or a PDF into a short narrated video that ends with a question, in your own voice and your students’ languages, we’d pick Chasca, which we make. Kinoslide suits math derivations and lessons you also want as slides, Scholarly long lectures with question checkpoints, and Scrimba Explain quick lessons from a question, especially on code. Gemini Notebook (formerly NotebookLM) is free for summarizing your own sources. For course videos made from your documents, Chasca makes lessons of up to 30 minutes in chapters and Scholarly up to 45; for a presenter on camera, use an avatar tool such as Synthesia or HeyGen.
How did we choose and check these tools?
- What’s included: tools that turn a teacher’s own material, such as notes, a document or a topic, into a narrated lesson video for you.
- How we checked: we read each tool’s own pricing, help and documentation pages between 2 and 4 November 2026 (dates under each section). Where a page is silent, or a tool’s own pages disagree, we say so. Prices change, so check before you buy.
- Our bias: we make Chasca. We say plainly where another tool is the better choice, and every claim about another tool links to its own pages.
- Not compared: avatar tools such as Synthesia and HeyGen, which make a different kind of video.

Chasca: best for lesson notes into short videos that end with a question
Chasca turns a topic, your lesson notes (a PDF, Word file, slide deck, Markdown or text), a photo of a worksheet or your own script into a narrated whiteboard lesson. It writes the script, or speaks yours word for word, and draws each scene stroke by stroke as the narrator explains it, usually in under a minute for a one-minute video (Chasca for teachers).
- Good for remembering: explainers and lessons end with a question to answer from memory, then a short recap, the kind of recall practice our guide for teachers recommends. Paste a question with its answer choices and say which is right, and a quiz video keeps every choice on the board and circles the right one (how to make a quiz video).
- Good for math and science: equations in math notation, written line by line as the narrator explains them, graphs plotted from their functions, and tables, geometry, trees and flowcharts computed exactly (diagrams). In Arabic, equations in Arabic-Indic digits run right to left, as they’re taught (Arabic math lessons).
- Good for your voice and their languages: a custom voice from about a minute of reading, on every plan (custom voices), or a recording of you teaching as the narration. The 30 narrators each speak all 79 languages, so the same lesson can go home in a family’s language.
- Also: six drawing styles, including Chalkboard and Crayon; Leda, a narrator for younger audiences; captions; MP4 downloads with SRT and VTT subtitles for your LMS; and share links you can switch off. Paid plans make lessons of up to 30 minutes, told in chapters past six minutes.
- Watch out for: students can’t click an answer: the question is part of the video. To fix a line, fix your notes and make the video again; subtitles, style or music change for free. Accounts are for ages 13 and up, so for younger classes the teacher runs the account. Check every equation and fact before class.
- Free and price: two free videos up to 1 minute each, watermarked, with no card; then Solo $9.99 a month for 30 minutes, Plus $19.99 for 70 and Pro $49.99 for 200, which adds your logo and a credit line (pricing). Schools and districts can ask about volume pricing (Chasca for education).
Kinoslide: best for math derivations and lessons you also want as slides
Kinoslide makes lessons from course material, a PDF, notes or a prompt, for educators, tutors, exam-prep providers and training teams. It has five looks, among them Dry Erase (a marker board, or chalk in Blackboard) and Presentation (animated slides that also export as a deck).
- Good for: math lessons. In Dry Erase, “Formulas are set from LaTeX and drawn in a handwritten style” and rewrite themselves as a derivation moves, and worked examples go line by line. Your own 100+ word script is read word for word in most looks, Pro adds storyboard review and scene edits, and credits roll over.
- Watch out for: narration comes in 11 languages (its pages disagree on which plans get them), and voice cloning and your own recording aren’t mentioned. PowerPoint must be exported to PDF first. Videos run up to 5 minutes on Basic, at 720p, 10 on Pro and 15 on Scale.
- Free and price: 4 credits at signup (a credit is a minute) for videos up to 1 minute “with a small watermark”, from one PDF of up to 10 pages; the home page says “4 minutes a month”. Basic is $30 a month, or $24 billed yearly, for 50 minutes; Pro $100 or $80 for 100; Scale $600 or $480 for 500, with 5 seats.

Scholarly: best for long lectures with question checkpoints
Scholarly is a study platform for students, researchers and professionals. Its Video Lectures turn PDFs, Word files, PowerPoint decks with speaker notes, images of notes, pasted text, YouTube links or a topic into narrated, animated lectures with chapters, captions, a transcript, question checkpoints and an AI chat.
- Good for: long lectures that students study in Scholarly. Paid lectures run up to 45 minutes, in five modes, among them Illustrated (hand-drawn) and Manim Math Animation, with “equations with real math typography”. “Use my script as written” keeps your wording, narration comes in 70+ languages, and re-narrating a lecture in another language costs 1 credit.
- Watch out for: the narrators are AI only (“it is not a recording of your own voice”), and “There is no timeline editor”: to change a lecture, you change what went in and make a new version.
- Free and price: one lecture of about 2 minutes at 720p, with Scholarly branding, watched and shared in Scholarly, with “No MP4 download”. Premium is $30 a month, or $15 a month billed yearly, with 15 credits a week; Laureate is $99 a month with 80. Both add MP4 downloads and 1080p. A lecture is 1 credit, plus 1 past 15 minutes or 2 past 30.

Scrimba Explain: best for quick lessons from a question, and for code
Scrimba Explain makes “a sequence of slides with spoken narration”, holding code, diagrams, formulas, images and quizzes, built while you watch. You ask for one on scrimba.com, in ChatGPT and Codex through a plugin, or from Claude and other MCP tools, and can attach files.
- Good for: computing classes, since its slides show real code with the narration pointing into it; quizzes students answer right on the slide; playlists for a whole curriculum and a player you can embed on your class site; and changes you type in plain words.
- Watch out for: Explain writes the lesson from your question and files, and picks the voice. Narration comes in 33 languages, and the length isn’t published. Downloads (an MP4 with VTT subtitles), switching off the watermark and commercial use need Pro.
- Free and price: five explainers with a free account (for life on its plans page, a month on its API page). Pro, with 100 a month, is $49 a month, or $24.50 a month billed yearly ($294). More in Scrimba Explain vs Chasca.

Gemini Notebook: best free option for summarizing your sources
Gemini Notebook, NotebookLM’s new name since July 2026, makes Video Overviews of the sources in a notebook, free within usage limits that refresh every five hours, up to a weekly cap.
- Good for: a quick visual summary of readings you’ve already gathered, at no cost. You pick Explainer, Short (about 60 seconds) or Cinematic, a style such as Whiteboard, a language (80 options for Explainer) and a focus, and you can download the video from most notebooks.
- Watch out for: there are no script, voice or branding options. Choosing a style is for users aged 18 and over, and Cinematic is English only and 18+. A video can take more than 30 minutes to make, Google warns that videos may contain inaccuracies or audio glitches, and its pages don’t mention equations or subtitles. More in NotebookLM video overviews vs Chasca.

Synthesia and HeyGen: when you want a presenter
Synthesia and HeyGen make avatar videos, with a presenter talking to camera rather than a lesson drawn on a board. That’s a different kind of video, so we haven’t compared them here. If students should see you, our course video guide suggests recording welcomes on your phone and letting drawings carry the explanations.
How to choose
- Is it for you or for your class? A summary of readings for yourself: Gemini Notebook, free. A video for students: you’ll want your voice, their language and a download.
- Math on the board? Chasca, Kinoslide and Scholarly’s Manim mode write equations, and in Arabic, Chasca writes them right to left. Check every symbol before class.
- Questions for students? Chasca ends explainers and lessons with a question to recall and makes quiz videos; Scholarly puts question checkpoints in its lectures, and Scrimba Explain’s quizzes are answered on the slide.
- Their languages? Chasca narrates in 79, Scholarly in 70+, Scrimba Explain in 33 and Kinoslide in 11.
- Your own voice? Chasca, on every plan.
- A whole course from your documents? Chasca makes lessons up to 30 minutes, told in chapters, Scholarly up to 45 and Kinoslide up to 15, but keep each video under six minutes where you can (how to make videos for an online course).
- Code? Scrimba Explain.
