An AI-made explainer can look polished, sound confident and still get a fact wrong. Before you share one with your class, a study group or a teacher, you need to know whether what it says is true. That is a different question from whether it was made with AI.
This guide covers two cases: a video someone else made that you want to pass on, and one you made yourself with an AI tool. The core method is the same in both. List the claims, check each one against sources you trust, and fix, cut or flag anything you cannot confirm.
Low-effort AI videos are not everywhere. One study of biomedical science videos on YouTube and TikTok screened 1,082 videos and judged 5.3% of them to be probably AI-generated and low quality. Still, a single wrong fact in a revision video is enough to mislead you before a test.
How it works
How to make and check an explainer with Vidi
Start from material you trust
Paste your lecture notes, the chapter you are studying or the question in your own words, and say how long the video should be. Starting from your own course material gives you something concrete to check the draft against.
Check the script scene by scene
Vidi drafts the script scene by scene before anything is animated. Compare each line with your notes or textbook. Fix wrong facts, numbers or wording, and soften anything that sounds more certain than your source.
Watch, fix a scene if needed, then share
Watch the finished video with sound and then with the sound off, reading the captions. In explainer videos you can change a single scene with a note instead of starting again. When it is right, download it and say what you checked it against when you share.
Is it AI? and Is it true? are different questions
Many guides about AI video teach you to spot whether a video was made by AI: odd hands, faces, lip-sync or watermarks. That is a different job from checking whether the video is right. One verification guide draws the line this way: knowing where a video came from tells you one thing, but checking each claim is what decides whether its message can be trusted.
For an animated or narrated explainer, visual glitches matter less. You may already know it was made with AI, or you made it yourself. What you need to know is whether the facts, numbers and diagrams are correct.
Detector tools and labels do not answer that. Detectors try to say AI or not AI, and they can get even that wrong: YouTube's automatic system penalised a human-made Kurzgesagt science video as AI-generated junk. A missing AI label also proves little, because labelling relies heavily on creators disclosing it themselves. And remember the reverse: a video made with AI is not automatically wrong, and a human-made one is not automatically right.
Check each claim against sources you trust
This is the step that actually tests accuracy. Pause the video and write down every factual claim: definitions, numbers, dates, names, cause-and-effect statements and anything shown in a diagram. A short explainer with one idea per scene may only have three to five key claims, which keeps this manageable.
Then compare each claim with a source that people have checked. The Indiana University library guide on fact-checking AI recommends comparing what AI says against known, human-verified sources. For school work, your textbook, course notes and teacher are good places to start. An ordinary web search helps with general claims; look at publication dates as you go.
Watch for vague, sweeping statements, and either back them up with an outside source or cut them. If the video names a study, book or expert, look it up. If you cannot find it, the same guide suggests using it as a lead to search for a real source. Until you find one, do not repeat the claim.
Fact-check sites such as FactCheck.org and PolitiFact focus mostly on politics, so they are of limited use for a biology or maths video.
Check who made it and where the pictures come from
If the video is someone else's, find out who stands behind it. Read the channel's About page and the video description for an AI disclosure, and look for YouTube's 'Altered or synthetic content' label. Try to find the earliest posting of the video, and ask whether it came from a known organisation, an official account or a new profile with few followers. Comments from people who work in the field can point out errors.
For images, take three to five clear frames from different parts of the video and run each through a reverse image search, such as TinEye, to see where else they appear. That catches pictures that were borrowed, mislabelled or invented. It will not tell you whether an animated diagram of a cell is drawn correctly; for that, compare it with the diagram in your textbook.
A trustworthy creator is a good sign, but even careful creators can get a claim wrong, so still check the claims that matter. Be wary of a video that makes you feel strongly: AI-made media is often built to provoke a reaction, and a dramatic claim nobody else is reporting is a warning sign.
If you made the video yourself
Checking is easiest before the video is finished. If your tool shows you a script, read it against your notes line by line before anything is animated. Changing words is quicker than remaking scenes.
A few habits help. Keep the video short and give each scene one idea, so each claim is easy to find and check. Give the tool your own notes or the chapter rather than a bare topic, so the draft starts from material you trust. Pay extra attention to numbers, units, dates, names, equations and labels on diagrams, since one wrong figure can change the meaning.
Then watch the finished video twice: once with sound and once with the sound off, reading the captions. Listen for mispronounced terms and for phrases that sound more certain than your source.
When you share it, add a short note saying what you checked it against, for example the chapter of your course textbook. If someone spots a mistake later, fix it and share the corrected version rather than leaving the wrong one up. Check your school's rules on AI-made work before you hand it in.
Ways to check an AI-made video, and what each can and cannot tell you
| What it tells you | Where it falls short | |
|---|---|---|
| Checking each claim against trusted sources | Whether each statement in the video is actually correct | Slow, and only as good as the sources you check against |
| Checking the creator and any AI disclosure | Who stands behind the video and whether AI use was declared | A reputable creator can still get a claim wrong |
| Reverse image search on frames | Whether pictures were borrowed, mislabelled or appear elsewhere | Does not test whether a diagram or animation is correct |
| AI-detection tools | Whether frames or faces look synthetic | Answers AI or not, not true or false, and can be wrong |
| Platform AI labels | Whether the uploader or the platform flagged the video as AI-made | A missing label proves nothing, since labelling relies heavily on self-disclosure |
| Reviewing the script before rendering (your own video) | Lets you catch and fix errors before anything is animated | Only works if your tool shows the script, and you still need a trusted source to compare with |
Limits worth knowing
- Checking claims takes time and is only as reliable as the sources you check against. If your notes are wrong, a video made from them will be too.
- No tool can confirm a video is accurate for you. Detectors and platform labels say at most whether something was made with AI, and both can be wrong or missing.
- Vidi drafts scripts with AI, and AI can get things wrong. Vidi does not fact-check a script you paste in, so you check it. Research with Vidi checks that each quote is really on the page it cites, but not that the reading of it is right.
- Free Vidi accounts get one free vertical 15-second video. Paid plans make videos up to 5 minutes.

Can an AI detector tell me if an explainer video is accurate?
No. Detectors try to say whether a video is AI-made, not whether its claims are true, and they can get that wrong too. YouTube's automatic system once penalised a human-made Kurzgesagt science video as AI junk. To test accuracy, check the claims against trusted sources.
If a video has no AI label, can I trust it?
Not on that basis. Labels such as YouTube's 'Altered or synthetic content' rely heavily on creators disclosing AI use themselves, so a missing label does not prove a video is human-made. And a human-made video can still be wrong. Check what it says.
Are short videos like YouTube Shorts more likely to be low quality?
In one study of biomedical science videos, Shorts made up 34.3% of the YouTube videos examined but 37 of the 47 judged to be low-effort AI slop. It covers one subject area, so do not stretch it too far, but it is a reason to take extra care with short clips.
The video cites a study I cannot find. What should I do?
Treat the claim as unconfirmed. Search for the study by its title, authors or topic. If a real source turns up, check that it says what the video claims. If nothing turns up, do not repeat the claim, and do not share the video without fixing or cutting that part.
What should I do if I find a mistake?
Do not share it as it is. If you made it, fix the script or the scene and check again. If someone else made it, you can skip sharing it, share it with a clear correction, or tell the creator. Telling classmates what was wrong helps them too.
Does Vidi fact-check the videos it makes?
No. Vidi drafts scripts with AI, and AI can get things wrong. You can review and edit the script scene by scene before it is animated, and in explainer videos change a single scene afterwards with a note. For papers, Research with Vidi ties each claim to a quoted page, but you still check the meaning.
