In their own words
Jenova UI/UX Prototype Generator
Jenova UI/UX Prototype Generator turns natural-language descriptions into visual prototypes for iOS, Android, and web apps. It can create connected screens for flows such as onboarding, navigation, dashboards, settings, and edge states. Generated designs draw on iOS Human Interface Guidelines, Material Design, and modern web conventions. Users can provide brand assets or describe a visual identity, then refine layouts, colors, typography, and other details through follow-up messages. Persistent memory carries design language across sessions, and conversation history and memory sync across web, iOS, and Android. Sketch or image input and clickable prototypes are supported. The generator is also available through the Jenova API, and the listed platforms include Android, API, iOS, Linux, macOS, web, and Windows. Its output is visual prototypes rather than code repositories or production design files. A free plan offers core features with limited usage. Plus costs $20 a month, billed monthly, with higher usage limits and specific AI model selection. Jenova’s privacy policy says chat history and uploaded files are not used to train its own AI models.
pen.dev
pen.dev is a canvas for building software and a vector design tool integrated with development environments. Its editor works with components, variables, themes, scripts and shaders, and can import Figma files and HTML. It can export to HTML, CSS and Tailwind, as well as PNG, JPEG, WEBP and PDF. Users can work with its integrated agent or connect external agents through MCP; the available plans specify how many agents can run in parallel. Documented integrations include Claude Code, Codex, Gemini CLI, Antigravity, OpenCode, Kiro and Claude Desktop. Integrated provider options include OpenAI, Anthropic, Google Gemini, Cursor, GitHub Copilot, xAI, OpenRouter and other API-key providers. Its.pen design file is open JSON with an open schema. Tools include a Chrome extension for importing webpages, IDE extensions and an npm-installed CLI requiring Node.js 22.19 or later. The pricing page says pen.dev stays free until plans launch. The Free plan is free; Pro is $16 a month; Ultra is $48 a month.
