Constraint-Aware AI Prototyping for Product Design Teams

A visual prototyping tool that lets designers modify interfaces directly while AI handles bounded implementation work in the background.

The Problem

Product designers using prompt-driven builders often receive prototypes that are only 70 to 80 percent correct. Repeated prompting is slow and unpredictable: changing one button can alter unrelated screens, while long generated outputs still require careful review. Designers therefore continue moving pixels and editing copy manually in Figma despite the potential time savings from AI.

Potential Solution

Build a Figma-connected prototyping product centered on direct manipulation rather than a blank prompt box. Designers select an element, specify the intended change through contextual controls, and preview a constrained patch that preserves locked components, layout rules, and established design tokens. The first version should focus on reliable copy, component-state, and localized layout changes rather than generating entire products.

Why Now?

Teams are experimenting with AI prototyping, but current prompt-first tools frequently produce incomplete or overly broad changes. Growing frustration with chatbot-style interfaces creates an opening for AI that operates invisibly inside an established design workflow.

You’re comfortable delivering the right artifacts at the right time using modern, AI-enabled tooling, from translating Figma designs into functional prototypes or production-ready code, to leveraging tools like Cursor, Claude, or similar systems to accelerate design and development workflows.

AI+PO/BA - what are you doing besides analysis with AI?
I quite like setting up HTML prototypes because they work really well for gathering feedback. I've also connected Claude to Figma for generating static wireframes, which cuts the early-stage design loop significantly. I create interactive prototypes using Claude design. You can then deploy them on something like Railway so that people can see them online. Beyond prototyping, AI is instrumental for all sorts of documentation in Confluence/google docs etc. A lot of previously manual work now is completely out of the picture - PRDs, SOPs, meeting minutes, - the best part is that it doesn't only create new documents, but can also keep the existing documents up to date, which previously was a particularly hard job to do. I like to think about AI as a competent junior who needs precise instructions. The quality of output scales directly with the quality of the brief — which, it turns out, is just good BA practice applied to a new tool. You already know how to write clear requirements; that skill transfers almost directly. What I'm curious about: are people keeping their prompts/briefs somewhere reusable, or rebuilding them from scratch each time?

The Best AI Prototypes Are Designed to Prove You Wrong

Most product teams treat prototypes as miniature success stories. The demo works. The model responds. The interface looks convincing. Everyone leaves the meeting feeling like the idea has momentum. But that can be exactly the wrong outcome. A useful AI prototype shouldn't just prove that something *can* work. It should expose the assumptions most likely to make the product fail. That's the more disciplined view [Goji Labs](gojilabs.com/.../from-idea-to-ai-prototyp...) takes in its recent discussion of AI prototyping: a prototype should test whether the product is worth building, not simply whether the technology is capable of producing an impressive output.  **The First Question Shouldn't Be About the Model** A surprising amount of AI product work still starts with questions like: * Which model should we use? * Should this be an agent? * Do we need retrieval? * Can we automate this workflow? * Should we build a chatbot? Those are implementation questions. The more important question is: **What user or business outcome are we actually trying to improve?** If that answer isn't clear, the prototype can become technically interesting without proving much of anything. **Every AI Idea Has a Weak Point** Maybe users don't actually want the feature. Maybe the data is incomplete. Maybe the model isn't reliable enough. Maybe the workflow can't tolerate uncertainty. Maybe the economics are terrible. Maybe the system requires so much human review that the automation doesn't save any work. Goji's recommendation is straightforward: identify the riskiest assumption and design the prototype around testing that first. That's a much better use of prototype budget than polishing the UI around an unanswered fundamental question. **Test the Workflow, Not the Screenshot** AI demos tend to focus heavily on output quality. Does the answer look good? Does the recommendation sou...
