The Real Problem

Not a code tool.

Lovable, Cursor, Claude Code — they all answer the same question:
"How do I build it?"

Bulup answers a different question:

  • What should I build?
  • How should it work?

Think before you build.

Idea Workshop

From idea to product architecture in minutes.

Describe your product in plain English. Bulup returns a structured product architecture — features, user roles, flows, and a scoped MVP — ready to hand to your team.

  • Brief Builder for founders who don't know where to start
  • Confidence indicators — see what Bulup assumed vs. understood
  • Feature priority matrix — visual, draggable, scope-ready

UX Flow Builder

Every screen. Every state.
Before Figma opens.

Bulup maps your entire product as a connected flow diagram — screen by screen, state by state. Onboarding. Core actions. Error handling. Edge cases. All of it. Generated from your product architecture.

  • Infinite canvas — pan, zoom, click to expand any screen
  • Community templates — real product patterns, ready to use
  • Export as Figma-ready spec sheet
See the Flow Builder
Design System Studio

A real design system. Not a color palette.

Bulup generates complete token architecture, typography scale, component specs, and export-ready CSS, Tailwind, and Figma variables. In one generation.

  • WCAG contrast audit built in — AA pass/fail per color pair
  • Dark + light mode generated together
  • One-click export: CSS / Tailwind / Tokens JSON / TypeScript

Product Brain

Your product has a memory now. Every decision, revision, and "why we chose this" stored, searchable, and available whenever you need context.

  • Auto-logs every Bulup generation
  • "Ask your product" semantic search

Handoff Center

Everything your team needs. Without the meeting. PRDs, UX specs, design tokens, dev docs — exported in formats your team can use immediately.

  • No Bulup account needed to view
  • Generate shareable links instantly

Not a code tool.

bulup doesn't compete with Cursor, Lovable, or Claude Code. It feeds them. You use bulup to think clearly. Then hand the output to your tools and your team.
