The AI understands context and asks for confirmation before destructive actions.\n2. **Authorization check:** Only your configured Telegram user ID can interact with the bot. Anyone else gets a rejection message.\n3. **Daily reminders:** At 9am, 2pm, and 6pm the bot automatically sends a summary of your pending tasks.\n4. **Midnight maintenance:** At 1am, any recurring tasks with a past due date are silently rolled forward to their next occurrence.\n5. **Task storage:** All tasks are stored in an n8n Data Table with fields: `taskname`, `duedate`, `Priority`, `Notes`, and `Recurrence`.\n\n### Setup\n1. Connect your **Telegram Bot** credentials (create a bot via @BotFather on Telegram).\n2. Connect your **Anthropic API** credentials.\n3. In **Check Authorized User** \u2192 set the comparison value to your Telegram User ID (find it via @userinfobot).\n4. In **Send AI Response to User** \u2192 replace `YOUR_TELEGRAM_CHAT_ID` with your Telegram Chat ID.\n5. Create a **Tasks** Data Table in your n8n project with columns: `taskname` (text), `duedate` (date), `Priority` (text), `Notes` (text), `Recurrence` (text).\n6. Re-link all four Data Table tool nodes to your new table, then activate the workflow."
