Every launch asset, from one logo

Asset Asserter turns one icon and one logo into every image and every word your launch needs.

75 image sizes

One upload becomes every size the App Store, the web and seven social networks require.

129 text fields

Copy is checked against each platform's real character limits before you paste it anywhere.

19 platforms

Export the whole bundle as a zip, named the way each platform expects.

Every platform, with its real numbers

Each platform is one file of Zod schemas describing what it needs. Nothing is guessed at export time.

Bring what you have

An Icon Composer bundle, a square profile picture, an SVG logo, an SVG wordmark. Any one of them is enough to start, and whatever is missing is reported rather than faked.

No model calls, by design

Copy comes from deterministic templates over your brand brief. If you want an AI to write it, connect your own client to the MCP gateway: it reads each brief and writes the words back, and every value is still checked against the platform's own limits.
