CLICK ANYWHERE. GO DEEPER.

The bottleneck moves from building to choosing.

When software becomes easier to produce, the scarce skill is knowing what deserves to exist. VidPrep keeps the insight connected to the speaker's exact words.

FAQ

Questions before you begin.

Is VidPrep another AI summary tool?

No. A summary is only the map. VidPrep helps you choose an interest, explore it, take notes, and trace every important idea back to its source.

What happens when a video has no captions?

Free processing does not subsidize ASR. You can connect your own OpenAI API key to transcribe it and continue.

Do two videos have to be in one playlist?

No. You can submit two completely unrelated video links and review the total duration before processing.

Which languages are supported?

VidPrep pairs English with Chinese, Japanese, Korean, Arabic, French, Spanish, German or Portuguese.

Find what sparks your curiosity.

Learn it in your language. Go as deep as you want—and never lose the path back to the source.
