Reel Thumbnail Variant Generator from Figma
After a Figma reel is rendered, this workflow generates three AI cover-image variants from the frame's hook text, posts them to Slack for a pick.

What it does
Generates and selects a scroll-stopping thumbnail for each reel. Once the captioned ElevenLabs clip is built from a Figma frame, it creates three AI cover-image options based on the frame's hook line, posts them to Slack for a quick pick, and binds the winner to the reel before it goes into the posting queue.
When to use it
Use it when thumbnail quality drives your reel performance and you want fast A/B-style choices without a designer mocking up covers each time. Pairs well with teams optimizing click-through on feed previews.
How it works
- 1A webhook fires when a reel clip finishes rendering from a Figma frame.
- 2The frame's hook text is read to seed cover prompts.
- 3An image model generates three thumbnail variants.
- 4The variants are posted to Slack for the editor to select one.
- 5A logic step captures the chosen variant and attaches it to the reel.
- 6The reel with its selected thumbnail is queued for multi-platform posting.
