Automatically triage & improve Todoist tasks with GPT-4.1-mini

How it works (high-level)

This workflow automatically triages new tasks created in Todoist in the last 5 minutes. It improves the task description, assigns a priority (P1–P4), and sets a realistic due date based on your current workload.

Main flow steps

  • Schedule Trigger — runs at a chosen interval.
  • Get many tasks (Todoist) — fetches all tasks created in the last 5 minutes.
  • AI Agent (LLM) — receives the new task plus clear rules to:
  • Rewrite the task description in an imperative style.
  • Score and set the priority (1–4) using Impact × Urgency × Risk.
  • Schedule a due date that respects workload and avoids overbooking.
  • get_open_tasks — provides the agent with the full list of open tasks to check daily capacity.
  • update_task — applies the improved description, chosen priority, and due date back into Todoist.

Setup steps Time required: ~5-10 minutes.

  • Configure Todoist credentials (API token) and OpenAI credentials in the respective nodes.
  • Adjust the Schedule Trigger to how often you want the system to check for new tasks.
  • Optionally, fine-tune the scoring and scheduling rules inside the AI Agent system prompt.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/7938/7938.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
