CimmichThe private memory layer for Immich
Live · Open source
Your photo library stores images.Cimmich remembers what they mean.
Your archive holds the people, places and stories only you can recognise. Give those connections a home, then use them to find your way back to the photos that matter.
Community preview. Self-hosted with Docker beside an existing Immich photo library.
- Matching that improves
- Confirm who someone is, refresh, and Cimmich uses what it learned to find the next possibilities.
- Find the intersection
- Combine people, places and events to find the photographs that connect them.
- Take the knowledge with you
- Export your decisions and linked documents without copying the original media.
Your original media and Immich database stay untouched, on infrastructure you control.
VirgilAI learning manager
Live · Open source
Stop collecting things to learn.Start knowing what to do next.
Articles, courses and saved tabs become a backlog faster than they become knowledge. Virgil turns them into a learning plan and prepares a lesson for the time you have.
Self-hosted Chrome extension and web app. Requires your own Google Cloud project and model credentials.
- Keep the useful part
- Pin a passage or page to a course, question or deadline. Its source stays attached.
- Check what stuck
- Use a recall check to find what you understand and what needs another look.
- Let progress change the plan
- Answers, missed questions and deferrals change what Virgil prepares next.
Your words can overrule its assumptions. Correct what Virgil thinks you know and the next lesson uses your correction.
