Telegram AI Bot Starter — Claude-powered chatbot (Node + Express)

About this tool

A production-ready starter kit for building Telegram bots powered by Claude (Anthropic). Drop in your API keys and have a natural, context-aware AI chatbot running in minutes. Includes per-chat conversation history, typing indicators, rate limiting, prompt caching to cut API costs, and an Express health-check endpoint for easy deployment on Railway, Render, or any Node host. Clean, fully commented code designed to be customized and shipped.

Good to know

This is a starter template, not a hosted service. You supply your own Telegram bot token and Anthropic API key, and Anthropic usage is billed to your own account. Conversation history is kept in memory, so it resets when the bot restarts (swap in Redis or a database for persistence — the code is structured to make this easy). No database or paid services required to run.
