KofAI Note is an AI second brain for people who save more information than they can manually organize.
When you find a useful post, article, video, or discussion, share it into KofAI Note. The app captures the source content, then uses AI to generate a structured note that is searchable, editable, and ready to ask about later.
Core features:
- Share extension capture from browsers, social apps, and any app that supports sharing text or URLs
- AI-generated title, summary, tags, key insight, and record type
- Five record types: decision, idea, backlog, worklog, and note
- AI chat over your saved knowledge
- Offline-first local storage
- Cloud sync after sign-in
- Data export to Markdown zip or JSON
- In-app account deletion
Usage limits:
The free release includes a daily AI allowance that resets the next day.
KofAI Note Pro Subscription:
Upgrade to Pro for unlimited AI analysis and AI chat:
- Monthly: US$1.99 / month
- Yearly: US$14.99 / year (save ~37%), billed in your local currency
Subscriptions auto-renew through your Apple ID and can be cancelled anytime in Settings.
Free users can also watch an optional rewarded ad to extend their daily AI quota — ads appear only when you choose them.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Get started with your own content or try a sample. Subscription plans now show local store prices with clearer purchase and restore status. Your input stays in place if analysis fails, making it easier to retry. We also improved English text, large text, and small-screen layouts.
