Hey HN — solo dev here. Built this because I wanted a private AI assistant on Telegram without paying $20/month for ChatGPT Plus or managing API keys.

For $1.99 you get your own Railway instance with Gemini 3 Flash included free. The gateway handles model routing, conversation memory, and multi-channel support. You can also bring your own key for GPT-4, Claude, Groq, OpenRouter.

The interesting technical bit: setup wizard talks to the gateway via WebSocket (config.get -> config.set -> config.apply) because the HTTP wrapper blocks /setup/* routes when the setup password is cleared post-provision. Took a while to figure that one out.

Stack: Node.js gateway, Railway one-click deploy, automated provisioning (~7 min end-to-end).

Happy to answer any technical questions.
