Deep Dive: Switching from Saner.AI to Atomic
Trade-offs, installation & data architecture
What you trade away
It covers capture, links, and cited chat, but its mobile capture, integrations, and overall polish are less mature than Saner.AI's managed workspace.
How to deploy Atomic
Download the macOS/Windows/Linux desktop release, use Atomic Cloud, or self-host its three-service Docker Compose stack
What it takes to run
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
Why fork Atomic instead of vibe-coding a Saner.AI clone?
The visible AI personal knowledge loop is buildable, but a credible replacement needs more than the first screen. Saner.AI earns its keep through polish, sync, importers, so expect a weekend or multi-day build and a narrower personal scope.
