Turn plain-language chat like “Tomorrow 9 AM: write blog post” into neatly organised Todoist tasks with GPT-4o and n8n—zero code.

🪄 Ultimate Personal Todoist Agent

Turn natural-language requests into perfectly-organized Todoist tasks—all on autopilot inside n8n.

“Add Finish quarterly report by Friday afternoon ” → the agent creates the task, sets the due date & priority, and even drops it into the right project. ✨

🌟 Why this workflow rocks

• All-in-one Todoist super‑powers – create, update, complete, move, archive… every major Todoist endpoint is wired up (tasks, projects, sections, labels, comments).
• LLM‑powered intent detection – an OpenAI model interprets plain-English (or emoji‑filled!) messages so you don’t have to remember slash‑commands.
• Minimal setup – just two credentials and you’re live.
• Battle‑tested building block – use it as‑is, or plug the Todoist Agent node into your own agents & chatbots.

🧩 How it works (under the hood)

[Trigger / Chat message]
        │
        ▼
[🗂️ Orchestrator Agent]  ← OpenAI Chat Model + Short‑term Memory
        │                 ↳ Parses intent & entities
        │
        ▼
[🤖 Todoist Agent]       ← 15+ Todoist endpoints
        │                 ↳ Executes the right call (create, update, complete, etc.)
        ▼
[Done ✅  ]

The Orchestrator is an example. In production you can drop it and simply expose the Todoist Agent as a tool for any other agent workflow.

🎛️ Customising & extending

Idea	How to do it
Notion / Sheets sync	After the Todoist Agent node, add a Notion or Google Sheets node to log completed items.
Voice commands	Swap the chat trigger for a Speech‑to‑Text node (e.g. Whisper).
