How it works
From Messy Idea to Working Code, Fast
Tired of AI misinterpreting your ideas and breaking things? There's a better way.
02
Get prompts that work
BrainGrid analyzes your codebase and crafts well structured prompts that include:
- Codebase context
- Scope and constraints
- Task dependencies
- Detailed implementation steps
- Acceptance criteria
- Spec'd test cases
03
Improve your app
Feed prompts to your coding agent and automatically review its code against your spec.
Works seamlessly with:
Cursor
Claude Code
Codex
Replit
Lovable
Any Agent
The AI Productivity Drop-off
AI coding moves fast, until it doesn't
AI coding agents are great for starting new apps, but extending or maintaining them is another story.
I Don't Know What I Don't Know
You can't plan for details you don't know exist. Without guidance, it's easy to miss edge cases that cause failures later.
AI Misinterprets What I'm Doing
Short prompts turn into big assumptions. You asked for a tweak, and got a redesign instead.
I'm Stuck in the Fix Loop
A small bug becomes a late-night spiral. Every fix breaks something else, and you end up further from done.
The Unfair Advantage
Less Back-and-Forth. More Building.
BrainGrid helps you plan, prompt, and ship with confidence. You get clear specs, perfectly scoped tasks, and precise prompts so your coding agent builds it right the first time.
Turn ideas into buildable requirements
Stop wrestling with vague prompts. BrainGrid helps you capture your thoughts in plain English and turn them into AI-ready requirements so your coding agent knows exactly what to build.
Use Anywhere
Feed tasks into any coding agent through MCP, CLI, or a simple copy and paste. BrainGrid works wherever you build: Cursor, Claude Code, Replit, Lovable, and more.
Engineering-grade prompts for your coding agent
Break features into structured tasks with goals, context, and acceptance criteria so your agent knows what to do next.
Automatic reviews for peace of mind
Ensure that your agent's code meets your requirements and does exactly what you meant it to.
What AI Coders are saying
It Just Works Better
Over 2,000 builders combine their vision and domain expertise with a proven AI coding workflow that delivers real, working results.
From broken to working in one rebuild
“I rebuilt a broken feature with BrainGrid and it worked this time. The quality of the product requirements it spits out is just fantastic. I make very few edits and it gives me a lot more confidence that I'm building thoughtfully and sequentially.”
Kaleen C.Pilates Entrepreneur and Builder
Thoughtful and structured approach
“I was really impressed with the thoughtfulness of it, the structure of it. It worked really lovely. I was really happy with how it ingested the PRD and went through with the first step of the tasks.”
Paul C.Supply Chain Exec Turned Builder
80% faster, one day to ship
“My second project went probably 80% faster than my first one. I basically had that one up and running in one day. For me and the way I was working, it was definitely a game changer.”
