Free study videos
Is there a free AI that makes a short narrated video explaining a concept?
Updated by the Vidi team
Your first 15-second video is free. No credit card required.
Several AI tools can turn a concept into a short narrated video. They differ a lot in what free actually means. Some give you one video for life, some a few credits a month, and some only a watermarked or link-only video.
This guide covers the free options that suit studying, what a good study video looks like, and how to check the result so you don't learn something wrong. Tool details can change, so confirm the current free limits on each tool's own site before you rely on them.
How it works
How to make a short study video with Vidi
Paste what you're studying
Paste the chapter, your lecture notes or the question in your own words, and say how long you want the video. Choose the narration language first, because the script is written in it. A free account gets one 15-second vertical video, so keep it to one concept.
Check the script
Vidi drafts the script scene by scene. Read every line against your notes or textbook and fix anything wrong or unclear before it is animated. AI drafts can be wrong, so treat it like a first draft from a teaching assistant.
Watch it, then watch it again
Vidi narrates, animates each scene and adds captions, so it works with the sound off. Download the video and replay the part that confused you on your phone or laptop. Then test yourself without the video.
Which free options suit studying
Start with tools that build the video from your own material, because that keeps it close to your course. Google NotebookLM's Video Overviews use the sources you upload and make narrated slides, pulling in images, diagrams, quotes and numbers from your documents. Google says the format is effective for explaining data, demonstrating processes and making abstract concepts more tangible. You can pick Explainer for a fuller overview or Brief for the core ideas, and tell it your level and what to focus on. If you want to study a concept for free from your own documents, it is a good first thing to try.
Scholarly is built for students and accepts typed or handwritten notes. Its free tier is one 2-minute video at 720p with no card, but it is branded and link-only, and MP4 download needs a paid plan.
For programming, the Explain Video Generator by Scrimba, listed in ChatGPT, says it makes code walkthroughs and is free to start. SlideSpeak lets you make your first explainer from slides or a PDF for free.
General video makers may fit studying less well. Fliki's default script is hook, problem, solution, call to action, and OpenArt says a full explainer usually needs at least 100 credits, from $14 a month.
What makes a good study video
Keep each video to one concept. If you need to understand three things, make three short videos rather than one long one. Aim for something short enough that you would happily rewatch it the night before a test.
Give it a simple shape: a question you want answered, a few clear steps, and one takeaway at the end. Put one idea in each scene, with a picture and a spoken line that match. Captions let you follow along with the sound off.
Tell the tool who you are. NotebookLM lets you describe your learning goals and audience, for example "I know nothing about this topic; help me understand the diagrams in the paper." In any tool, try saying your year level and what you already know, so the script is pitched at the right level.
Feed it the exact section you are stuck on, not the whole course, so the video stays on the one thing you need to understand. It also makes the script quicker for you to check.
Check it before you study from it
An AI video can sound confident and still be wrong. Google's own help page says Video Overviews, including voices and visuals, are AI-generated and may contain inaccuracies or audio glitches. Vidi also says its scripts are AI drafts that can get things wrong, so treat every tool here the same way.
Check every definition, number, formula and diagram against your lecture notes or textbook. Look closely at any simplifications and analogies, and make sure they still match what your course says. If the tool lets you read the script before it renders, as Vidi does, fix mistakes there rather than after.
Then do something active. Watching is not the same as remembering. Close the video and explain the concept out loud, write three questions about it, or make flashcards. Scholarly itself suggests making flashcards or a quiz from the same material after the video. Rewatch only the part you got wrong.
Common mistakes to avoid
Thinking free means unlimited. Scholarly gives one video for life, Fliki gives 3 credits a month, and Vidi gives one 15-second video. Plan what you will use the free credit on.
Spending a one-shot credit on a broad topic. Narrow your notes to one concept first.
Leaving it to the last minute. Google says a Video Overview can sometimes take more than 30 minutes to generate, though it runs in the background.
Following old tutorials. Some older guides say NotebookLM video is web-only, but Video Overviews have since come to the Android and iOS apps. Google's help page also now refers to Gemini Notebook, so the name you search for may have changed.
Assuming you can keep the file. Scholarly's free video is link-only and Fliki's free export is watermarked 720p. Check download rules before you start if you need an offline copy.
Submitting an AI video as your own work without checking your course rules.

Limits worth knowing
- AI-made videos can be wrong. Google warns its Video Overviews may contain inaccuracies, and Vidi's scripts are AI drafts too. Check every fact against your course material before you study from it.
- Free tiers are small. Vidi's free account makes one 15-second vertical video with a small logo; longer videos up to 5 minutes need paid credits. Other tools limit free use in similar ways.
- A video does not replace active recall. You still need to test yourself, explain the idea in your own words and practise questions.
- Tool names, limits and features change. We could not confirm NotebookLM's free daily limits or download options, so check each tool's current terms before you rely on it.

Is NotebookLM Video Overviews really free?
Video Overviews rolled out to all NotebookLM users in English in July 2025. One article mentions a two-video daily limit for the Cinematic format, but we could not confirm free limits for other formats. Some extras are paid: Google says co-creating with producer notes is only for Google AI Ultra subscribers. Check the current name and limits.
Can I use my own lecture notes or handwritten notes?
Yes, with the right tool. NotebookLM builds the video from documents you upload. Scholarly accepts typed or handwritten notes as PDF, Word, image or pasted text. Vidi lets you paste your notes or a chapter and edit the script before anything is animated. Using your own material keeps the video close to your course.
How long should a study video be?
Aim for one concept per video, short enough to rewatch before a test. Build it as a question, a few clear steps and one takeaway. Vidi's free video is 15 seconds, enough for one idea; paid Vidi videos go up to 5 minutes. Scholarly's free video is up to 2 minutes.
Can I get the video in another language?
Often, yes. Make Tech Easier reports that Google added access to up to 80 new languages for NotebookLM's Video Overviews, and your sources can be in English while the video is in another language. Vidi narrates in 74 languages, including Spanish, Hindi, Arabic, Japanese and Vietnamese. Choose the language before you create the video.
Can I make and watch these videos on my phone?
NotebookLM's Video Overviews are now in the Android and iOS apps, with playback-speed controls, though older guides say web only. Vidi's free videos are vertical 9:16 with captions on by default, so they fit a phone screen and work without sound.
How long does it take to generate a video?
It varies by tool. Google says a NotebookLM Video Overview can sometimes take more than 30 minutes, and it runs in the background while you do other things. Start early rather than the night before an exam, and leave time to check the result.
Can I hand in an AI-made video for an assignment?
Check your course and school rules first, because policies on AI-generated work can differ. Even where it is allowed, check the facts and say how you made it. Vidi says you own your scripts and may use the videos it makes for you under its terms of service.
