CONTENT CREATION
On-demand Trello card narration requested from Slack
A teammate posts a Trello card link in Slack, and the workflow fetches that card, narrates it with ElevenLabs, archives the MP3 to Dropbox.

What it does
Gives anyone a self-serve way to turn a specific Trello card into audio without opening the board. A teammate drops a card URL into a Slack channel; the workflow resolves the card, builds a spoken script with OpenAI, voices it with ElevenLabs, stores the MP3 in Dropbox, and replies in the same Slack thread with a ready-to-play link.
When to use it
Use it when audio requests are ad hoc rather than every card — for example, a teammate wants to listen to one dense card before a meeting. Keeps the action in chat where the request already lives.
How it works
- 1A Slack message containing a Trello card link is posted in the watched channel (trigger).
- 2A logic step parses the card ID from the URL and ignores messages without one.
- 3Trello returns the card's title and full body.
- 4OpenAI shapes the content into a clean narration script.
- 5ElevenLabs synthesizes the MP3.
- 6The MP3 is archived to a Dropbox 'On-Demand' folder.
- 7The workflow replies in the Slack thread with the Dropbox audio link.
