What they did

Open-source customer support platform with customisable AI agents and a chat widget for your website or app.

How it went

Self-host it and plug in your docs so the agent answers from your own knowledge.

Step by step

  1. Open the GitHub repo and read the README (setup changes over time).
  2. Clone it: git clone https://github.com/cossistantcom/cossistant
  3. Open the folder in Codex or Claude Code and ask it to walk you through setup and the config file.
  4. Add your own API keys as the README describes, then run one small test before real use.

Watch out for

Read what the code does before running it with your accounts; start with test data.
