Get started in 3 steps

  1. Pick the chat app you already open every day; Telegram bots are the quickest to create and test.
  2. Lock the bot to your own user ID so it only answers you, and keep API keys out of the chat itself.
  3. Start with one command (a summary, an alert or a search) and add more once it runs reliably.

Have an AI answer your phone and waste scammers' time

Fed up with scam calls, a developer diverted his mobile to a Telnyx number where an OpenAI live voice agent answers. A classifier labels each call as spam, scam or genuine and steers the bot: scammers get strung along, sales calls get a polite no, and real callers get a message taken. He can steer the bot from Telegram mid-call.

Let Claude search your personal WhatsApp chats from a server in your own Cloudflare account

A developer wanted Claude on his phone to read his WhatsApp messages without WhatsApp Business or a server running all day, so he built a small MCP server that runs on Cloudflare Workers. You link it once like WhatsApp Web; it syncs when asked and once a day into a SQLite Durable Object in your account. It can read and search chats but cannot send anything, and it pulls contact names from Google so search works by name.
