Bailey

An open-source AI assistant that runs ready-made solutions: on your own machine, with your own AI key.

Early days. This is release 0.0.1. It installs one command, bailey doctor, which checks that your computer has what the assistant will need. The assistant itself arrives in 0.1.

What Bailey is for

Getting AI to do one real job reliably is still a project. Someone writes the instructions, connects the tools, supplies the documents and the keys, checks that it works, and keeps it working when something changes.

Bailey runs solutions instead: complete, versioned packages for one job, such as answering customer emails, qualifying leads or writing a weekly report. A solution carries its instructions, skills, tools, knowledge and small apps. Bailey installs it in one step and asks only for the keys it needs.

• Your machine, your key. It runs locally and opens in your browser, with the AI provider you choose: Anthropic, OpenAI, or any OpenAI-compatible endpoint, local models included.
• It asks before it acts. Every tool is either read or write, and a write tool asks before it runs: once, always for this assistant, or no.
• Your documents stay yours. Files you add are indexed on your computer, and answers cite the passage they came from.
• Open formats. Skills are Agent Skills, tools are MCP servers, apps speak Postern, and a solution is an Agent Plugins folder, so its parts also load in other clients.
• No telemetry.

Solutions can be free, or bought on Sigrix, where builders sell what they make for Bailey.

Check your machine

uvx bailey doctor

pipx run bailey doctor works as well. It checks, and says how to fix what is missing:

It exits 1 when a required check fails, and bailey doctor --json prints the same answers for a script. It reads your machine only: no network call, no file written.

What comes next
