Answer support questions from your docs with Telegram, OpenRouter and pgvector

## AI Support Agent With Human Handoff Answers customers from your own docs, and hands off to a human instead of guessing. ### How it works 1. A customer messages your Telegram bot. 2. The knowledge base is searched and the best match is scored. 3. If the match is strong, an AI agent with chat memory answers from your docs. 4. If the match is weak, or the agent is unsure, the customer is told a human will reply. 5. Your support chat gets the question. Your answer goes to the customer and is saved as a new FAQ, so next time the AI knows it. 6. Every question, answer and error is logged in Postgres. Use it with Sync Google Drive docs to a Postgres pgvector knowledge base with change detection.
