Do you want to change Charles by asking Claude Code in plain words?
Self-tune or Claude Code?
Self-tuneIn every Charles
Charles adjusts its own settings: one small, tested step at a time. Undo it, or switch it off.
Claude CodeOn the 4 GB server
You change whatever you like, in plain words: new rules, new cards, your own ideas.
The server is billed by DigitalOcean and a Claude plan by Anthropic, not by us.It runs on your own server: about $6 a month, paid to DigitalOcean.

Claude Code
Change Charles in plain words. Claude Code, on your own server, reads the code and makes the change. It needs a bigger server, about $24 a month.
Fetch, live on bitcoin.
Fetch is an add-on that watches one market trade by trade and says what it's waiting for. It's separate from Charles's own plan, which checks once a day and holds for weeks. Every dot is a real trade by someone in the market.
Any Charles can turn Fetch on. It trades practice money: no real money moves, and nothing here is a result or advice.
