## What is Knowcast?

Drop links, PDFs, EPUBs and long articles into Knowcast, and it automatically turns them into podcasts, written explainers, comics and notes. On your commute, a walk, or before bed, you can listen and actually absorb the content.

Knowcast is an AI knowledge tool that turns complex content into easier-to-understand formats.

You can import web links, PDFs, EPUBs and TXT files, or paste a long passage directly. The app converts source material into content suited for reading, listening and review: podcasts, written explanations, comics and key notes.

Great for:

- Finding a long article but not having time to read it now
- Saving many web pages, PDFs and ebooks without getting through them
- Making professional content simpler and easier to understand
- Learning by listening during commutes, walks, or before sleep
- Highlighting key passages while reading and turning them into notes
- Asking follow-up questions about any part you do not understand

Core features:

[Source Library]
Import links, files and text, and keep web articles, PDFs, EPUBs and long passages in one source library.

[One-Tap Conversion]
Turn source material into podcasts, written explanations, or comics. Choose the format that fits how you understand best.

[Listen Queue]
Generated content goes into your queue, where podcasts, text and comics are managed together so you can keep reading or listening anytime.

[Read While Listening]
View the transcript while audio plays. Important passages can be highlighted so you can really understand what you hear.

[Notes]
Highlights saved while reading and listening are gathered into notes for review, sharing and later reference.

[AI Q&A]
Ask follow-up questions around the current content without copying the context again, so your understanding can go deeper.

[Free to Use]
All core conversion features are currently free. Sign in only when you want account sync and cross-device recovery.

Knowcast is not just a bookmark folder. It helps you actually digest what you save.

Give it the content you meant to read but never finished. Try a different way to understand it with Knowcast.
