Problem
Users already live in chat, but most business software asks them to open another app or dashboard. uiless lets a builder connect a signed API once and expose that system inside chat channels — so users can book, track and pay in the conversation.
What shipped
- Multi-tenant AI gateway that routes conversations to each builder’s connected API.
- Signed API connectors that expose a builder’s system inside chat.
- Channel adapters for WhatsApp, Telegram, LINE, Instagram, Messenger and Web.
- Auth — API calls run as the real user; the model can’t impersonate them.
- Usage billing per conversation.
- OpenAI-style tool calling that maps a chat request onto the right connector API call.

- Marketplace where builders list apps and users bind them in-chat.
- Connector setup in about an hour. Free to start, billed per conversation.
- Hosted models built in, so builders don’t need a separate LLM key.
