Zalcro is the pre-build planning tool for AI app builders. Jumping straight into prompting usually leads to a doom loop where the AI loses context and breaks your app. Zalcro solves this by mapping out your architecture before you begin. It generates a build-ready plan so your AI knows exactly what to do. Whether you use Lovable, Replit, Cursor, or Claude Code, Zalcro gives you step-by-step prompts you paste directly or connect via MCP. Build better. Plan before you prompt,

Hey Product Hunt 👋
I'm David, founder of @Zalcro After 10+ years in product management, I’ve seen the exact same pattern repeat. When you skip planning at the beginning, things falls apart near the finish line.
Today, AI lets anyone build. But jumping straight into building usually leads to that frustrating wall where things go wrong, and you break three features trying to fix one tiny bug. You burn through credits and you're tempted to start all over.
I built Zalcro to fix this. It plans your app from the start and provides you a blueprint your AI can actually follow.
How it works
Describe your idea. Just explain what you want to build in plain language
Answer a few questions: Zalcro gives you suggestions to easily nail down the requirements.
Get your blueprint: It generates your architecture, a visual diagram, and a Prompt Pack with step-by-step prompts.
Copy, paste, and build: Paste the prompts into your AI tool one after the other. Happy building!
Zalcro also fits right into your existing stack. It connects directly via MCP to Cursor, Claude Code, and Codex, and you can export all your blueprints to your computer or Google Drive.

I'd love to hear from you! What has been your biggest headache when trying to build a product with AI coding agents?
I'll be hanging out in the comments all day to answer questions and hear your feedback!
To answer your question, my biggest headache is the AI forgetting a decision I made twenty prompts earlier and quietly rewriting something that was working fine. I gotta say the idea of handing it an architecture diagram plus prompts in order sounds like it would stop a lot of that. Curious how it holds up on a messy idea instead of a clean todo app.
@founder92 Thanks Nela! That memory gap is the root cause of so many build failures. Zalcro fixes it by giving the AI a stable reference point before you write a single line of code.
On messy ideas, it starts with clarifying questions to figure out exactly what you’re building, then gives you options with recommendations before generating anything. Try it with something totally half-baked, no login required, just drop your idea on the home page and see what comes out. Would love your take!
@davidoduk this looks to be a great way to increase success and accuracy of the build. Do all the planning and specification design upfront to guide the agent down the path you want. Best of luck with the launch.
