Meeting & class recording
Record and transcribe, then get highlights, action items, decisions, and study cards.
An AI second brain for students, makers, and teams
Capture lightly. Let your notes swim back with meaning.
KoiNote turns recordings, ideas, photos, and web links into a searchable, connected, reviewable knowledge base. Stop chasing your notes. Let them come back useful.
Four capture modes, one knowledge pool
Turn scattered moments into knowledge you can use again.
Instant ideas
A sentence, image, or link can be tagged automatically and connected to older notes.
Photo OCR
Capture books, whiteboards, formulas, and cards. AI restores structure and turns them into notes.
AI weekly reports
Transform loose records into learning traces, project reviews, and suggested next steps.
From capture to review
Every input gets its own organizing path.
Real product screens show how recordings, ideas, web links, search, and summaries become reusable knowledge.
Recording to summary
Turn live audio into meeting highlights and study-ready notes.
Idea to structure
Speak a quick thought and let KoiNote shape it into title, tags, and next steps.
Web link to note
Drop a link and compress long content into a summary you can revisit.
Useful can still feel playful
A pond of ideas that keeps growing.
The fun is not noise. It is the moment an old note connects to a new idea, a class becomes flashcards, or a weekly report tells you what really moved forward.

Our mission
Everyday knowledge deserves to be cared for.
Important things often begin as a recording, a passing idea, or a whiteboard photo. KoiNote keeps those fragments alive by connecting, compressing, reminding, and presenting them.
