Tile Vault
plannedA dated archive of the thumbnails of the best islands, so you can see what changed the day their curve turned around.
What this tool would do
- Captures the thumbnail of every tracked island each time a change is detected.
- A timeline per island, each thumbnail set against the player curve.
- Filters by genre, to read the visual codes of a row before producing your own.
- A direct hand-off to Vortex Thumbs to produce a variant against a reference.
What it needs to exist
- The Archive tool for curve inflections and change detection.
- Dated image storage, keeping the original URL and the capture date.
Why nobody does it today
Epic has offered thumbnail A/B testing for free since May 2025. So the gap is not measurement, it is material: knowing what works today in your genre and being able to produce two genuinely different variants. No tool keeps Discover's visual history.
