Thinkr

PRD to prototype

An interactive prototype. From your spec.

Prototype generates a working, clickable prototype from your PRD. Multiple pages, real components, real flows. The Product Manager produces something the design team can react to in the same hour the spec is finished.

Before & after

From a spec the design team has to imagine to a prototype they can click.

Before Thinkr

  • The spec describes screens in prose; everyone pictures something different.
  • Design starts from a blank canvas days after the PRD is done.
  • Feedback waits until there is something to click — usually weeks later.
  • The Product Manager has no way to test the flow before engineering builds it.

With Thinkr

  • A working, multi-page prototype is generated straight from the spec.
  • Design reacts to something real in the same hour the PRD is finished.
  • Click through the flow and catch the gaps before anyone writes code.
  • Click through it in the browser — no build, no deploy, no waiting.

It plans before it builds

Prototype maps the whole structure first — every screen, every flow, every interaction — then builds the pages in parallel. You see the plan and can edit the page list before a single screen is generated.

  • Plans every screen and flow before building
  • Builds all pages in parallel
  • Edit the page list before generation runs

Refine via chat

Describe the change. "Add a confirmation modal after submit." "Change the CTA copy to ‘Continue.’" The prototype updates immediately.

  • Natural-language refinement of components, flows, copy
  • Only the affected pages are regenerated, not the whole prototype

Interactive preview

Click through the prototype in-browser. Test the flow before the design team picks up the spec. Test the spec before engineering picks it up.

  • Browser-based interactive preview
  • Multi-page navigation
  • Real component interactions (modals, forms, transitions)

Questions

Frequently asked

Can AI build a prototype from a PRD?
Yes. Prototype plans every screen and flow first, then generates a clickable, multi-page HTML prototype straight from your spec — something the design team can react to in the same hour the PRD is finished.
How is this different from v0 or Lovable?
Those build from a fresh prompt. Prototype builds from your finished, critiqued PRD — the same spec the rest of Thinkr works from — so the result reflects the actual requirements instead of a new guess.
Can I change the prototype after it is generated?
Describe the change in chat ("add a confirmation modal after submit") and only the affected pages regenerate. Click through the result in the browser to test the flow before engineering picks it up.
