🪄 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.

🛠️ What you’ll need

Credential	Where it’s used	How to set it up
OpenAI API	Orchestrator & LLM nodes	Paste your OpenAI secret key into an OpenAI credential in n8n.
Todoist OAuth2	Todoist node and HTTP Request node	Log in Todoist from your browser to set up credential in n8n.

> That’s it—no webhooks, no extra secrets. > Tested with gpt‑4o‑latest – the fastest & most accurate model in our trials.

⚡ Quick‑start (5 minutes)

Import the JSON template (hit ▶️ Try it out on the n8n template page or drag‑drop the file into your canvas).
Select your credentials in the two credential dropdowns.
Click Test workflow. In the sample Function node, tweak the message field (e.g. “Tomorrow at 9 am: write blog post”). Run → watch your new Todoist task appear.
(Optional) Swap the Function node for your favourite chat trigger (Telegram, Slack, WhatsApp, Discord, you name it).

Boom—your personal Todoist genie is alive! 🧞‍♂️

🧩 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).
