Telegram AI Assistant with Rate Limiting & Auto-Reset via Google Sheets

This workflow implements a robust Telegram AI assistant that tracks user interactions via Google Sheets to enforce rate limits, preventing excessive API usage and service abuse. The main flow triggers on Telegram messages, logs counters per user (chat ID in Column A, count in Column B), uses switch logic to check limits (default: 3 messages), and routes to AI processing or block/warning responses. A separate scheduled reset flow clears all counters at configurable intervals (e.g., daily, hourly).

Key benefits include precise cost management for AI APIs, fair access enforcement, and scalability for demos, trials, customer service, or educational bots. It solves unlimited interaction issues by silently blocking over-limit users or sending warnings, ensuring sustainable operations without built-in platform limits.

Ideal use cases: Cost-controlled demo bots, trial-period AI assistants, anti-abuse measures in public bots, or quota-based customer support. Setup requires Telegram bot token, Google Sheets API credentials, and an AI model; customize limits and reset schedules via node conditions and cron expressions for production readiness.
