About Decosa
Decosa makes AI tools that each do one real job and show their work.
Tools, not a chatbot
Each tool does one job a professional already does by hand: digest a deposition, write the visit note, appeal a denial, fill a form. You can try every one on a sample without signing up.
Open models
The tools run on open-weight models whose names, versions and licences are listed on each tool's page, so you can run the same models yourself. One exception: if our own model fails, the site guide (Ask Decosa) may be answered by Anthropic's model, as Where your data goes says. No tool depends on it.
A signed record of every result
Each result is signed with what went in, what came out and which model produced it, so you or your auditor can check it later.
Measured in public
Every tool shows its time per task, cost per task and accuracy on a test set, with the caveats, and the date each was measured. A scheduled check re-runs the hosted tools on their samples, and each tool page shows its latest result, pass or fail. Where something isn't measured yet, we say so.
Hosted, or on your own hardware
Use a tool here, or run the same thing on your own server or Mac so your documents never leave. Self-hosting is in early access.
