A voice AI tutor for any YouTube video

taughtful.ai is a free AI tutor that teaches you any YouTube video out loud, the way a teacher would. Paste a YouTube link and the video plays right on the page. taughtful.ai reads the transcript, splits the video into sections using its chapters, and a voice tutor walks you through it, pausing the video where you need to think and generating the lesson's video in real time as it explains. Interrupt at any moment by voice to ask why, and the tutor answers, re-teaches that part, then picks the video back up.

Paste a YouTube link into taughtful.ai and a voice tutor watches it with you, pausing wherever you are stuck to re-teach that part out loud before the video carries on.

Which videos can it teach?

• Any public YouTube video with captions, in any language
• Lectures, tutorials, talks, explainers, and news
• Long videos: YouTube chapters become the lesson's sections; videos without chapters are split into sections automatically
• Paste a full link or just the video ID

It can't teach videos with captions turned off; private, removed, or region-restricted videos; or songs, gaming, and ASMR, which give a tutor nothing to teach.

A lesson video, generated while it teaches

As the tutor teaches, taughtful.ai generates the lesson's video live: diagrams, code, charts, and motion drawn in step with the voice. When you interrupt, it changes too, so the next thing you see is an answer to your question, not the next frame of a fixed clip.

How does a video lesson work?

1. Paste a YouTube link.
2. taughtful.ai reads the transcript and the chapters and builds the lesson's sections.
3. The voice AI tutor teaches section by section, pausing the video and generating the lesson's video in real time as it explains.
4. Speak whenever you are stuck. The tutor answers, then the video continues.

Tap any chapter to jump the tutor there. Select text shown in the video, like a formula or a line of code, and send it to the tutor to explain.

How is this different from a YouTube summarizer?

Summarizers turn a video into notes you read instead of watching. taughtful.ai teaches the video: it walks through it in order, explains it out loud like a teacher, pauses on the hard parts, and checks in with you. It does not help you skip the video; it makes sure you understood it.

Who uses it?

Students who want an AI to explain a lecture or tutorial video to them, self-learners working through a course on YouTube, and anyone who has watched a video and still didn't get it.

Why teaching this way works

• One-to-one tutoring is the most effective form of instruction ever measured: in Bloom's studies the average tutored student performed about two standard deviations above a conventionally taught class, better than 98 percent of those students. taughtful.ai puts that kind of tutor on any YouTube video you bring. (Bloom, "The 2 Sigma Problem", Educational Researcher, 1984)
• People learn more deeply from words and pictures together than from words alone, which is why the tutor generates the lesson's video as it explains instead of only talking you through the video. (Mayer, Multimedia Learning, Cambridge University Press)
• Retrieving what you just learned makes it stick far better than going over it again, which is why the tutor checks in and asks you questions as it goes rather than only summarizing the video. (Roediger & Karpicke, "Test-Enhanced Learning", Psychological Science, 2006)

Frequently asked questions

Which YouTube videos work?

Any public video with captions, in any language. Lectures, tutorials, talks, and explainers work best. Videos with captions turned off, private or removed videos, songs, gaming, and ASMR can't be taught.

Does it work with videos in other languages?

Yes. It uses the video's captions in any language, and prefers English when several are available.

Does it work on long videos?

Yes. YouTube chapters become the lesson's sections, and videos without chapters are split automatically, so an hour-long lecture is taught in parts.

Do I have to go through the whole video?

No. Tap any chapter and the tutor jumps there.

Can it read what's on screen?

Yes. Select text shown in the video, like a formula or a line of code, and send it to the tutor to explain.

Is the lesson video pre-made?

No. taughtful.ai generates it in real time as the tutor speaks, and it changes when you interrupt.

Is it free?

Yes to start: 10 voice minutes a day and 25 a week, no card needed. Pro is $15 a month or $144 a year, and Max is $39 a month or $372 a year, so annual billing saves 20 percent.
