Pick a provider, paste a key, Save. Each has a default model that can read photos. The sheet says the plain thing: a Claude Pro or Max plan cannot pay for another app, only an API key can, and it links to where you make one. Or add Yui inside Claude or ChatGPT and your plan pays.
The MVP is done and Yui is in alpha, open to anyone with an iPhone on iOS 26. Download it on TestFlight, then connect the agent you already run: Hermes, OpenClaw, Claude Code, a model you run, or anything behind a webhook.
Yui is open source under Apache 2.0. Star the repo, open an issue, or send a pull request.
Spare tokens on Claude or ChatGPT Codex? Your agent can pick a card off our backlog and open a pull request. Yui@home, like SETI@home.
