What you save actually comes back.
Share posts, articles, and YouTube talks into KofAI Note. AI turns them into a stack of cards — weeks later, search and chat bring them back when you need them.
How it works
Share it in
Tap share in any app and pick KofAI Note. No copy-paste, no deciding which folder it belongs to first.
AI turns it into cards
Title, summary, key insight, and tags are generated for you; the original text and source are kept. AI proposes — what it means is still your call.
Ask it back later
Weeks later, when a similar question shows up, search or chat brings it back — with its source and context.
Four ways things come back
Saving is just the entrance. What KofAI Note is really built for is bringing old content back when you need it.
Search
Keywords across everything you ever saved.
Chat
Ask in plain language; answers cite your own records.
Related records
Save something new and the related old records surface on their own.
Weekly review
What you never searched for comes back once a week.
A real use case
YouTube talk → study cards
Paste one link and 30 seconds later it is a stack of cards you can flip back through: a summary, key points, quiz questions.

Saving takes one second. Coming back is the hard part — that is why this product exists.
Read: read-later is the most polite way to delete somethingWho it isn't for
Said honestly up front, to save you a download.
- People who only need a one-off summary — a browser or a general AI tool is enough; no need to maintain another database.
- People who never revisit old content — the value is in retrieval, not in collecting.
- Teams that need collaboration and permissions — it is one person's second brain, not an enterprise knowledge base.
