Introducing the first version of Reforge Build. Built for product teams, AI prototyping that starts from your product, not from zero. Try it for free here or book a demo.
AI app builders are an incredible new superpower. But most are built for those building from scratch. Yet, most product teams aren't starting from zero.
You have an existing product. Real customers. A design system. Brand guidelines. Strategy docs. Customer feedback.
Using a 0→1 tool for 1→N work, you end up fighting the tool instead of working with it.
Generic prototypes that miss the mark
Describing your brand colors to AI for the 47th time

Reforge Build: AI Prototyping For Product Teams
Today, we are opening up the first version of Reforge Build. It’s AI prototyping built for product teams. It starts from your product, not from zero.
App Builders force you down a workflow of start from scratch → generate an app → deploy + host.
Reforge Build is designed around a product team’s workflow. Start from your product → plan with AI that knows your customers and features → explore multiple variants → collaborate internally → validate with customers.

Prototype From Your Product
https://fast.wistia.net/embed/iframe/iipkpv2ba8
Stop spending hours rebuilding your design with every prototype.
Reforge Build starts from what you already have. Use our browser extension to capture your product in one click or store your design guidelines.
Before: You describe your design system in a prompt, AI generates something generic, then you spend hours manually adjusting colors, fonts, spacing, and components to match your brand.
With Reforge Build: Capture your product screens in one click. Your prototype instantly matches matches your product’s design guidelines —right colors, fonts, and spacing from the start.
AI That Remembers Your Target Customers, Features, and Strategy
https://fast.wistia.net/embed/iframe/p534v23rvk
Your context shouldn't evaporate between prototypes.
Reforge Build captures and stores your customer feedback, target audience, product knowledge, data schemas, and strategy docs at both company and project levels. The AI pulls from this context automatically when building prototypes.
Before: Prototypes a pricing page with random tiers ($9, $49, $99), made-up features, and generic copy that doesn't reflect your actual product or customers.
With Reforge Build: With your context loaded, Reforge Build will generate a pricing page prototype with your actual tiers, real features, customer-specific language, and positioning that aligns with your strategy.
Plan Mode: From Idea To Structured Plan
https://fast.wistia.net/embed/iframe/fi9iixjmmo
Stop randomly prompting your way to clarity.
Plan mode helps you turn a raw idea into a structured, detailed plan before generating anything. It researches your context, brainstorms options, and creates a specification the AI can follow.
Before: You write a vague prompt like "build a dashboard." AI generates something random. You iterate 10+ times trying to communicate what you actually want.
With Reforge Build: Plan mode guides you through a structured breakdown—defining user needs, key metrics, layout priorities, and interactions—before generating. The first output is already close to your vision.
Generate and Explore Multiple Variants
https://fast.wistia.net/embed/iframe/0gucmrdtqa
Stop starting over to explore different directions.
Variants in Reforge Build lets you generate and compare multiple approaches simultaneously. Instead of prototyping one solution and hoping it works, explore several paths at once.
Before: You prototype variant A. To explore variant B, you start from scratch with a new prompt, losing your previous work and context.
With Reforge Build: Generate multiple variants of the same feature side-by-side. Compare them. Cherry-pick the best elements. Iterate from there.
Built-In Collaboration
https://fast.wistia.net/embed/iframe/6y4e2n5ja5
Stop losing context across Slack threads, Notion embeds, and Google doc comments.
With Reforge Build, share prototypes with your team. They comment directly on specific elements. Everyone sees feedback in context. Team members can remix your prototypes as starting points for their own iterations.
Before: You deploy the prototype, share in Slack, collect feedback in three different threads, manually compile notes, then try to recreate what everyone wanted.
With Reforge Build: Share the live prototype. Your team comments in place. You see all feedback in context. Collaboration happens where the work lives.
Reusable Templates
https://fast.wistia.net/embed/iframe/z2ohth3ho8
Stop rebuilding the same foundation over and over.
With Reforge Build, turn any prototype into a reusable template. Build once. Start from that foundation next time.
Before: You build a great onboarding flow prototype. Later, you want to prototype a different improvement, but you have to recreate the entire flow from scratch.
With Reforge Build: Save your onboarding flow as a template. Next time, you start from that foundation and iterate on it in minutes instead of hours.
Validate With Customers (Coming Soon)
Stop juggling prototyping and research tools.
With Reforge Build, you’ll soon be able to seamlessly connect Reforge Research and deploy an AI-interview or AI-survey that collects feedback, synthesizes it automatically, and surfaces key insights on your prototype.
Before: You build a prototype in one tool, manually schedule customer calls, take notes during interviews, then spend hours analyzing feedback in spreadsheets.
With Reforge Build: Send your prototype through Reforge Research. AI interviews users. Feedback comes back synthesized and actionable.
Scale Across Your Product Org (Coming Soon)
Stop siloing prototypes in individual accounts.
Coming soon, Team Accounts will give your entire product organization access to shared workspaces, centralized context, and reusable templates. Load your design guidelines, customer feedback, and product strategy once at the team level and everyone benefits.
Before: Each team member has their own account. They each upload different definitions of the target customer. They end up with prototypes optimizing in different directions.
With Reforge Build: One team workspace. Centralized context. Shared templates. AI operates in the same direction. New team members onboard in minutes. Your team builds from the same foundation.
Built for Product Teams, Not Solo Builders
Reforge Build isn't for everyone. If you're a founder starting from scratch or building a side project, there are some amazing tools for that.
But if you're on a product team with an existing product, real customers, and established goals —we are building Reforge Build for you.
This is the first version of Reforge Build, and it’s getting better every day.
