Der KI-YouTube-Summarizer von Summio macht aus jedem Video eine strukturierte, redaktionell aufbereitete Lesung in der gewünschten Tiefe: kurz, mittel, lang oder detailliert. Gratis fürs iPhone, in 27 Sprachen — und nach der Zusammenfassung kannst du mit dem vollständigen Transkript chatten, Zitate suchen oder unklare Stellen klären.

Common questions

Is there a maximum video length?

Practically no — Summio handles videos up to several hours. Very long lectures may take a minute or two to process.

Does it work with playlists?

Yes. Paste a playlist URL and Summio creates a collection where each video is summarised individually with cross-links.

What if the video has no captions?

Summio generates a transcript automatically using audio when YouTube captions are missing. Accuracy depends on audio quality.
