I kept rebuilding my vibe coded projects from scratch. So I built a tool to fix the actual problem.

I'm not a developer. I build agentic platforms and internal tools at my day job using AI coding agents. Same tools as everyone here

Claude Code, Replit , etc. And I kept hitting the same wall: great first few days, then everything falls apart because there was no real plan behind the prompts.

The fix was always the same: write an actual spec first. But most of us skip that step because we either don't know what a good spec looks like or we just want to start building.

So I built kaisho.ai — an AI-powered spec generator that takes your rough idea and produces a structured, build-ready spec optimized for AI coding agents. Think data models, user flows, edge cases, acceptance criteria, architecture assumptions — everything the agent needs to stay on track and stop hallucinating random decisions.

Three tools live right now:

• Idea to Spec — Turn a rough concept into a full implementation-ready specification

• Clone Spec — Paste any public URL and get a reverse-engineered spec of that product. Good for competitive research or "build something like X but better"

• Feature Spec — Generate a spec for a new feature based on your existing project spec. It understands your current architecture, data model, and patterns so the new feature actually fits instead of breaking everything

That last one has been huge for me personally. Once you have a base spec, adding features becomes way less chaotic because the AI has full context on what already exists.

You get free credits to generate your first spec so you can see the output quality before spending anything. I'm a solo founder building this with the same vibe coding tools you all use, so I genuinely want feedback from this community.

What's useful? What's not? What would you want from a tool like this?

Building in public, happy to share anything about the process.
