The agent uses OpenRouter, memory, Google Calendar tools, and Todoist tools to answer questions or manage events and tasks, then replies back in Telegram. Separate scheduled branches send calendar reminders and Todoist summaries, while webhook and error-trigger branches send Telegram notifications for external events and failures.\n\n### Setup steps\n\n- Configure Telegram bot credentials for the trigger and all Telegram send/get-file nodes, including the destination chat IDs.\n- Add OpenRouter credentials for the AI agent model nodes and select the preferred models.\n- Add a Groq API key or authorization header in the audio transcription HTTP request node.\n- Connect Google Calendar OAuth credentials and confirm the target calendars used by both the agent tools and scheduled reminder branch.\n- Connect Todoist credentials and verify the projects, task filters, and tool permissions used by the agent and summary branch.\n- Set the schedule trigger times for calendar reminders and Todoist summaries.\n- Configure the webhook URL consumers and switch conditions for the routed Telegram notifications.\n- Enable the error workflow and point its Telegram alert node to the desired admin chat.\n\n### Customization\n\nYou can adjust the AI agent prompt, model choice, memory window, Todoist and Calendar tool permissions, schedule timing, webhook switch routes, and the formatting code used for daily summaries or reminders."
