One Tool, Many Formats

criei.ai isn't a one-size-fits-all design tool. Each format type has its own canvas, frame, layout engine, and AI prompts specifically tuned for that medium. Here's what each one does and when to use it.

Mobile App

Generates iPhone-style screens with proper touch targets, navigation bars, tab bars, and mobile-first layouts. Ideal for app prototypes, pitch decks, and development references.

Best for: App prototypes, UI mockups, investor presentations

Web App

Creates full-width desktop layouts with sidebars, toolbars, data tables, and dashboard components. The designs are responsive and follow modern SaaS conventions.

Best for: Admin panels, SaaS dashboards, internal tools

Landing Page

Produces scrollable section-based layouts — hero, features, pricing, FAQ, footer. Each section is designed to stand alone while maintaining visual consistency.

Best for: Product launches, marketing sites, conversion pages

Logo

Generates multiple logo variations including wordmarks, icons, and combination marks. Each variation explores a different visual direction for your brand.

Best for: Brand identity, startup branding, concept exploration

Ad Creative

Optimized for advertising dimensions — Instagram feed and stories, Facebook ads, and Google Display Network sizes. Each creative includes proper safe zones and text placement.

Best for: Social media campaigns, paid advertising, A/B testing

Thumbnail

Designed for YouTube and video platform thumbnails with bold typography, attention-grabbing compositions, and proper aspect ratios (16:9).

Best for: YouTube channels, video content, course thumbnails

Social Media

Creates content for stories, reels, and feed posts across platforms. Each post follows the conventions of its platform (Instagram's square feed, vertical stories, etc.).

Best for: Content calendars, social campaigns, brand consistency

Not sure which format to pick? Start with the one closest to your end goal — you can always create another project in a different format later.
