Show HN: Telechat – Self-hosted Claude on Telegram/WhatsApp/Slack, no cloud relay

Short summary

Telechat is an open-source, self-hosted Claude AI bot that connects to Telegram, WhatsApp, Slack, and web chat from a single Node.js/Python process. Key features include smart model routing (Haiku/Sonnet/Opus based on query complexity, ~60% cost savings), per-user budget caps, a Desktop Bridge for remote tool-call approvals via push notification, and SQLite-backed persistent memory. Messages never touch a relay server — only the Anthropic API for inference.
