# Bender

> Bender is an AI mobile app UI generator built so the output doesn't look AI-generated: it produces a complete, themed, clickable set of mobile screens (real HTML and Tailwind, not static mockups) and refuses the common AI tells like the floating glass tab bar, gradient text, and Lorem-ipsum filler. It has built-in synthetic user testing that walks AI personas through the flow to surface usability friction before a real user or client sees it. Edit by chat, re-theme in one move, and export clean code.

Bender: Mobile app designs that don't look AI-generated, pressure-tested before you pitch. Bender's differentiator is output that does not read as AI-generated: it refuses the common AI tells (the floating glass tab bar on every screen, glassmorphism, gradient text, colored glow, the navy-and-gold fintech reflex, Lorem-ipsum and John Doe filler) so a screen set reads as authored by one team. Bender sits upstream of code generators (v0, Bolt, Lovable) and native app builders (Rork, Expo): it is the design-and-triage layer where a mobile app concept gets generated, themed, and pressure-tested before anyone writes production code. Its signature capability is synthetic user testing: AI personas tap through a clickable prototype, attempt real tasks, and return a usability report with friction pinned to the exact screen where the flow breaks. This is triage that surfaces usability problems early, not a substitute for testing with real users.

## What Bender does
- Generate a full set of themed mobile app screens from a text prompt, built to avoid the common AI tells (floating glass tab bar, glassmorphism, gradient text, colored glow, Lorem-ipsum and John Doe filler) so the set reads as authored by one team
- Consistent design tokens and theming across every screen
- Re-theme an entire screen set in one move
- Edit any screen by chatting with it; generate A/B variants and run a design critique
- Synthetic user testing: AI personas tap through your flow and pin friction to the exact screen where it breaks
- Clickable prototypes and a layers inspector
- Loading, empty, and error states generated for every screen
- Export clean HTML + Tailwind code from any screen
