IconsMint

You'll get 10 AI-generated icons when you sign up for free, and that's pretty much it for AI creation. You can still browse and download from their library of 100k+ icons with a 30 downloads per day limit, but if you need more AI generation you'll have to upgrade to the Starter plan which gives you 40 AI icons per month for $15.

Yeah, that's basically the whole point of their Extend a Set feature. If you generated 15 icons three months ago and now need five more, IconsMint will create new ones that match your original set's exact style and weight. It's honestly one of the most useful parts since you won't end up with mismatched icon families.

You'll probably get results that look similar to what other users are getting. IconsMint works best when you give detailed prompts because every icon is generated uniquely for each user, but vague descriptions kind of defeat that purpose and produce generic-looking sets.

You'll get a commercial license with the paid Starter plan at $15 per month, and there's no attribution required. The free plan doesn't include commercial rights though, so if you're using icons for client work or a product you're selling, you'll need to upgrade.

Yep, you can fine-tune stroke thickness for outline icons from Ultra Thin to Extra Bold completely free without re-generating anything. It's a slider adjustment that works on icons you've already created, which saves a ton of time when you're trying to match different UI weights.

IconsMint exports to SVG and PNG on all plans, but if you're on the Starter plan you also get Icon Font and SVG Sprite formats. The Font Kit export is pretty handy if you're working with web projects that need font-based icons instead of individual files.

Honestly, it depends on your workflow. If you're iterating heavily or working on multiple projects, 40 AI icons per month at $15 won't cut it and you'll hit that ceiling fast. The unlimited downloads from their 100k+ icon library helps, but the AI generation itself is capped.
