How this works
This workflow automates the prioritisation of your Todoist inbox tasks, helping busy professionals maintain focus by filtering and ranking daily to-dos without manual effort. It scans your inbox each morning via a scheduled trigger, uses OpenAI to analyse task urgency and importance based on descriptions and due dates, then updates priorities directly in Todoist for quick action. The key step involves OpenAI's intelligent evaluation, transforming a cluttered list into an organised schedule that aligns with your goals.
Use this workflow when you receive a high volume of tasks and need consistent, AI-driven sorting to tackle the most critical ones first, such as in project management or personal productivity routines. Avoid it for simple lists without descriptive details, as OpenAI relies on context for accurate filtering; manual review suits low-volume or highly subjective prioritisation better. Common variations include adjusting the cron schedule for weekly runs or integrating email notifications for priority shifts.
