The private memory layer for Immich
Your photo library stores images. Cimmich remembers what they mean.
Connect the people, places and stories you remember, then use those connections to find the photos that matter.
A separate app you self-host with Docker beside Immich. Your connections live in Cimmich's database. It never writes changes back to Immich or your original photos.

01 / Bring the story together
A weekend becomes more than a folder.
Bluewater Weekend brings its photos, journey, people and documents together in one place to return to.
-
02 / Keep the source nearby
Let a document explain the moment it belongs to.
Nora's invitation stays linked to both Nora and her birthday, where it can be found from either.
-
03 / Follow more than one thread
Ask for the event and the place.
Bluewater Weekend plus Bluewater Beach narrows the archive to the nine photos that belong to both.
Matching that learns from your decisions
One confirmation can uncover the next.
You know who belongs in your photos. Cimmich uses the faces you confirm to look for more, and leaves each decision with you.
Review a suggestion.
Confirm the person, choose someone else or leave the photo for later.
Refresh with what you know.
Cimmich rebuilds its matching evidence from your confirmed faces, then searches again.
See what comes back.
Review any new possibilities or doubtful tags. If nothing else is ready, return after adding more evidence.
Face matching needs a local Face-analysis provider and separately installed model files. Stories, documents and other organisation tools work without it.
What about a wrong tag or a difficult photo?
These fictional demo photos show the workflow, not a measure of matching accuracy.
Your knowledge should outlive one install
Move the library without leaving the story behind.
Cimmich reconnects unchanged photos by their contents, not only by where they live today. Move files or rebuild Immich and the people, events, places and documents you added can reconnect after a new inventory.
Your media platform
Immich
Keeps authentication, original media, thumbnails and its own library metadata.

Your memory layer
Cimmich
Keeps the people, stories, decisions and documents you add in a separate database.
Cimmich stores its own organisation. It does not write albums, tags, metadata or media back into Immich.
Edits stay honest
A changed file becomes a new asset instead of inheriting context automatically.
Take Cimmich with you
Export Cimmich's database and linked documents without copying original media.

Bring Cimmich to the library you already have.
Preview 18 requires exact Immich 3.1.0. The guided install has been tested on macOS and Linux Docker hosts; Windows has not yet been tested. Start with a no-change check of your setup, then install when the account, library and scope look right.
Prefer to explore without your own photos? The isolated Cedar House demo runs locally with fictional media. About the local demo.
