If you want to research across many sources, NotebookLM is the stronger tool. If you want to be taught, taughtful.ai is built for that.
NotebookLM helps you research your sources; taughtful.ai teaches them to you, out loud and live, with a video that changes when you ask a question.

You bring a YouTube video, a PDF or other document, or a topic, and one tutor teaches it to you out loud, section by section, generating the lesson's video in real time.

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 is built around that one-to-one tutor, teaching you rather than answering queries. (Bloom, "The 2 Sigma Problem", Educational Researcher, 1984)
- People learn more deeply from words and pictures together than from words alone, which is why taughtful.ai generates the lesson's video live, in step with the tutor's voice, instead of only reading a summary aloud. (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 taughtful.ai tutor checks in and asks you questions as it teaches. (Roediger & Karpicke, "Test-Enhanced Learning", Psychological Science, 2006)
