Cosmos vs Pinterest vs Kelu for Inspiration
Two of these are feeds you scroll; one is a library you keep. That single distinction settles most of the choice:
- Pinterest — the biggest discovery feed, now heavy with AI content and ads.
- Cosmos — a tasteful, ad-free discovery feed with an “keep your feed human” identity.
- Kelu — not a feed at all; a private library for what you save, wherever you found it.
Pinterest and Cosmos compete for the same job (discovery). Kelu does the other job (keeping) that neither really solves.
Pinterest: reach, with a catch
Pinterest still has the largest volume of visual inspiration anywhere, and it added an AI filter under Settings → Refine your recommendations. But the controls only reduce AI content, the “AI modified” label shows only after you open a pin, none of it applies to ads, and there’s no control for AI video. For a lot of creatives the feed stopped being trustworthy — the backdrop to the whole Pinterest exodus.
Cosmos: the tasteful feed
Cosmos is the polished anti-Pinterest: ad-free, no likes or comments, curated, with an option to hide AI-generated imagery. After a 2026 redesign it made collaboration free and leaned further into a social feed. Two honest caveats: the no-AI stance is a show/blur/hide setting, not a ban; and your saves live in Cosmos’s clusters, on Cosmos’s platform. App Store reviews also flag occasional slowness and crashes. It’s a lovely place to find things.
Kelu: the library you own
Kelu isn’t trying to be a feed — it has no discovery by design. It’s a private, tag-first library for screenshots and references you save from anywhere, including Pinterest and Cosmos, synced across iPhone, Mac, and the web, searchable in your own words, first 2,500 items free. No AI slop, because the only things in it are things you put there. It solves keeping, not browsing.
How they compare
| Cosmos | Kelu | ||
|---|---|---|---|
| Discovery feed | ✅ Huge | ✅ Curated | ❌ By design |
| AI content in feed | Reduced only | Hide setting | ✅ Only your saves |
| Ads | ✅ Yes | ❌ | ❌ |
| You own the library | ❌ | ❌ | ✅ |
| Your own tags + search | Boards | Partial | ✅ Core model |
| Cross-device sync | ✅ | ✅ | ✅ iPhone/Mac/web |
| Price | Free (ads) | Free / $8 mo | Free 2,500 items |
Bottom line
- Pinterest if you want maximum reach and can tolerate the AI-and-ads feed.
- Cosmos if you want a tasteful, ad-free place to discover.
- Kelu for the half neither solves: a library you own for the references you actually keep.
The healthiest setup is to pair them — discover on a feed you like, keep the results in Kelu so they’re yours. More on that habit in curation vs collecting.
