Criei

Criei turns natural-language prompts into designs for mobile apps, web apps, landing pages, logos, ad creatives, thumbnails, and social media posts. Users describe a design in plain language, watch screens appear on a canvas in real time, then download PNG files or refine screens with follow-up prompts. Listed export formats also include SVG, Expo, and website ZIP. The service supports prompt-to-UI generation, multi-screen generation, and code export.

The Standard Plan costs $19 a month, billed at $19/month. It includes 50 UI credits and 100 API credits per month, unlimited projects, and rollover of unused credits; each screen generation or regeneration uses one credit. The plan also includes one-click deployment to a custom subdomain and REST API access to generate, deploy, and manage designs. Terms grant generated designs a full commercial license without attribution requirements or additional fees. Criei is available on the web, iOS, and through an API. Users must create an account with Google OAuth and be at least 18. The terms say generated designs may have imperfections or need manual refinement, and specific results are not guaranteed.

Criei offers prompt-based design generation with multiple export options, credits, deployment, and API access in its Standard Plan. Users should allow for credit use and possible manual refinement of generated results.

Criei may suit people who want to turn written prompts into app, web, or marketing designs. Its API access and deployment option may also fit users managing design generation programmatically.

Criei turns plain-language prompts into designs for apps, websites, logos, ads, thumbnails, and social posts. It is best suited to solo creators and small businesses that want a quick starting point they can refine or publish. Its mix of screen generation, export formats, deployment, and API access is useful, but the monthly credit budget makes it a poor fit for unlimited iteration.

Overview

Users describe a design in natural language, watch screens stream onto a canvas, then download PNGs or refine screens with follow-up prompts. Multi-screen generation and code export extend the workflow beyond a single static mockup, while the homepage lists PNG, SVG, Expo, and website ZIP exports. The range is broad enough to cover both app interfaces and marketing assets; the service does not guarantee specific results, and generated designs may need manual refinement.

The Standard Plan adds one-click deployment to a custom subdomain and REST API access to generate, deploy, and manage designs. Generated work carries a full commercial license without attribution or extra fees, a useful provision for client and business projects.

Key features

• Prompt-to-UI generation: Natural-language instructions create screens, with multi-screen generation suited to projects that need more than a single concept.
• Streaming canvas and follow-up prompts: Screens appear in real time and can be refined conversationally. Each generation or regeneration uses a credit, so repeated changes draw down the monthly allowance.
• Exports and deployment: PNG, SVG, Expo, and website ZIP exports support different handoff needs; Standard also enables one-click deployment to a custom subdomain.
• REST API: Standard subscribers can generate, deploy, and manage designs through the API, making the plan relevant to workflows that need programmatic access.
• Commercial rights: The license allows commercial use without attribution or additional fees.

Pricing

Criei has no free plan. The Standard Plan costs $19 a month, billed $19/month, and includes 50 UI credits plus 100 API credits each month, unlimited projects, and rollover of unused credits. One credit covers one screen generation or regeneration. Unlimited projects therefore do not mean unlimited design attempts; the credit allowance is the practical constraint for frequent iteration.

Standard is the clear fit for users who need deployment or API access as well as a monthly design workflow. Those who only want to explore the generator must pay rather than start on a free tier. Subscription payments are processed through RevenueCat, and partial billing periods are not refunded.

Platforms

Criei is offered on web and iOS, with API access for programmatic use. The service requires account creation through Google OAuth, and users must be at least 18 years old.

Who it's for

The service presents use cases across real estate, restaurants, contracting, fitness, education, e-commerce, SaaS, and small businesses. It suits people in those fields who need generated design concepts or screens and can refine results when needed. The commercial license also makes it viable for paid work. It is less suitable for anyone who needs guaranteed design outcomes or expects to generate screens without watching credit consumption.

Pros and cons

• Pro: One workflow covers app and web screens as well as logos and marketing graphics, which broadens its use beyond UI mockups.
• Pro: SVG, Expo, and website ZIP exports, plus custom-subdomain deployment and REST API access on Standard, provide several routes from generation to delivery.
• Pro: Commercial use requires neither attribution nor extra fees.
• Con: There is no free plan, so trying the service requires a paid subscription.
• Con: Every screen generation or regeneration costs a credit, limiting how much iteration the monthly quotas support.
• Con: AI output can have imperfections and may need manual refinement; specific results are not guaranteed.

Alternatives

For a broader comparison, browse AI UI Design Generators. Choose UXPin if a free plan matters: after its 14-day trial, its Free plan offers two prototypes and 50 AI credits. Figma Make is an option for web and macOS users who want a Starter allowance of 150 AI credits per day and 500 per month, or a Professional Full seat with 3,000 monthly credits for $16 a month.

Relume may suit users who want a free forever starting tier with one project, one page, and read-only sharing. Paper offers a free tier with unlimited viewers and editors and 100 MCP tool calls per week. UX Pilot is another free-to-start option, with the first design free.

Visily is worth considering for a free monthly allowance: its Starter plan includes 300 AI credits, standard AI design, and limited boards and elements. artique offers a free tier and paid monthly plans. Banani has a free plan with 12 monthly credits and three daily credits, making it an alternative for users who want to begin without paying.

Verdict

Criei is a strong fit for small businesses and creators who want prompt-driven design across screens and marketing assets, then need export, deployment, or API access. Its broad output options and commercial license are compelling; the main reason to look elsewhere is the lack of a free plan and the finite screen-generation credits. Choose it when those paid workflow features matter more than unrestricted iteration.
