Where Cosmos is better
- Discovery and community. Cosmos shows you other people's collections.
- It is on your phone.
- Search by visual similarity, which folie does not have.
- You can start free.
folie is Mac only, has no phone app, does not sync between machines, and needs either your own Claude API key (about a tenth of a cent a capture) or a model running on your Mac.
Where folie is different
- It captures anything on your Mac's screen, not just images on the web.
- It is made for interface design: a capture is filed as a nav, a hero or a pricing table.
- With the Chrome extension, the real typefaces come from the page.
- Your files stay on your Mac. No account.
Which one to pick
If you want a social, image-led moodboard you can open anywhere, Cosmos. If you want a private library of interface screenshots on your Mac that you can search by what is in them, folie.
