Cost
$0 / forever (Open Source)
License
MIT
Hosting Model
Local or hosted (your machine or their cloud)
Platforms
desktopmobilewebself-hostedextensionone-click install
Installation
Download the macOS/Windows/Linux desktop release, use Atomic Cloud, or self-host its three-service Docker Compose stack
Operational Setup
The desktop binary installs cleanly, but first-run setup cannot finish without an embedding and generation backend, either an API key or Ollama plus downloaded models
Where Your Data Lives
Knowledge is stored as Markdown 'atoms' plus tags, chunks and sqlite-vec embeddings in Atomic's local/server data directory; cloud users keep that database on Atomic's hosted service, and cloud-model calls send relevant text to the provider
The Catch / Trade-off
It covers capture, links, and cited chat, but its mobile capture, integrations, and overall polish are less mature than Saner.AI's managed workspace.
