Capture thoughts without filing them first. Rediscover what matters through search, review, and optional AI organization.
Knowlume is a local-first knowledge inbox for thoughts, lessons, links, and small tasks.
Capture an idea immediately without choosing a folder. Organize it later with types and tags, find it through full-text search, or let daily review bring an older note back into view.
Free features:
- Fast text capture
- Manual types and tags
- Full-text search, favorites, and archive
- Daily knowledge review
- JSON data export
Knowlume Pro adds:
- AI summaries and tag suggestions for individual notes
- Suggested connections
- A brief generated from up to 12 recent notes
AI output is always presented as a suggestion. Nothing is added to a note until you choose to accept it.
Your library stays on device by default. Only content clearly shown for the current AI task is sent to a third-party AI service after your consent. AI output can be inaccurate and should be reviewed before use.
Knowlume contains no ads, third-party analytics, or cross-app tracking.
