FAQ

Questions about Trello + OpenAI.

How does GPT triage Trello cards?
New Card → OpenAI returns list, labels, due → Trello Update Card with predicted fields. Add "ai-triaged" label to prevent re-firing.
Can GPT expand a Trello card into a checklist?
Yes. Prompt: "return JSON array of checklist items needed to complete this card". Loop and Trello Add Checklist Item. Useful for one-line ideas → structured execution.
How do I auto-generate Trello card descriptions from a title?
Trello Card Created with empty description → OpenAI generates structured description (context, goal, success criteria) → Trello Update Card writes back.
Can GPT summarize Trello comments?
Yes. Get card comments → OpenAI summarizes in 2 sentences → pin as a comment so anyone arriving at the card gets the latest state.
How do I auto-move Trello cards based on text signals?
When a comment is added, OpenAI judges if it indicates card is complete. If yes, Trello Move Card to Done list. Reduces friction for teams that comment "shipped!" but forget to move.
Which model for Trello automation?
gpt-4o-mini for triage and classification (cheap). gpt-4o for description expansion. Don't over-spend on advanced models for card-level operations.
