Semantic search
Find anything in plain language — "sunset on the coast," "red dress, indoors." No tags required; the model understands the pixels.
Private, local AI media library
Your photos & video, understood — on your own machine.
Private, local AI for your whole library: semantic search, faces, places, video scenes, captions. No cloud, ever.

Everything, understood
One private library, six ways to find what's in it.
Faces & people
Group every shot of a person locally. Face vectors never leave your machine — no cloud face database, ever.
Places & events
Cluster by location and time into trips and moments, from EXIF you already have — no account, no map provider phoning home.
Video scenes & transcripts
Split clips into scenes, pull keyframes, and transcribe speech so video is as searchable as your stills.
Auto-tagging & captions
Every asset gets structured tags and a written caption from local vision models — browsable, filterable, yours.
Personalization
Learns your keep / reject taste over time and surfaces the frames you'd actually pick. It adapts to you, not the other way around.
How it works
Three steps. No cloud in any of them.
- 01
Point it at your library
Pick folders of photos and video. Nothing is uploaded — indexing runs on your machine.
- 02
It understands everything
Local AI tags, captions, finds faces and places, and splits video into scenes — all offline.
- 03
Search & rediscover
Ask in plain language, filter by person or place, and let it learn what you keep.
Private by architecture, not by promise.
Your media stays on disk. There's no server to trust, no account to delete, no breach to fear — because we never receive your library in the first place.
Pricing
Free forever. Pro once, if you want more.

FAQ
The short version.
Does anything leave my machine?
No. Indexing, search, faces, and captions all run locally. There is no telemetry and no account. The only optional network call is if you choose to bring your own compute key for a faster remote model — and that is off by default.
What does it cost?
The Free edition is $0 and open source under AGPLv3. Pro is a one-time $29 purchase — perpetual for that major version, no subscription.
Will it run on my computer?
If you have a reasonably modern Mac, PC, or Linux box with ~8 GB of free RAM and ~10 GB of disk for models, yes. The first run downloads about 3.5 GB of local models, then works fully offline.
