Length-aware Trello audio: full read for short cards, summary for long ones
When a card is labeled 'make-audio', it measures the body length and routes accordingly — short cards get verbatim narration, long cards get an OpenAI summary first.
How it runs
The automated pipeline, trigger to output.

What it does
Produces the right kind of audio for each card. It checks how long a card's body is: short cards are read word-for-word so nothing is lost, while long research dumps are condensed by OpenAI into a listenable summary first. Either path ends in an ElevenLabs MP3 archived to Dropbox.
When to use it
Use it when your cards vary wildly in length — quick notes alongside multi-page pasted articles — and you want a single workflow that handles both without producing 40-minute readings of raw text.
How it works
- 1A card gains the 'make-audio' label (trigger).
- 2A logic step counts the words in the card body and branches on a threshold.
- 3Short branch: the body is passed through as-is with light cleanup.
- 4Long branch: OpenAI summarizes the body into a 2-3 minute spoken script.
- 5ElevenLabs synthesizes the chosen text into an MP3.
- 6The MP3 is uploaded to Dropbox, foldered by the card's source list name.
- 7The Dropbox link and chosen mode (full vs summary) are commented on the card.
