BrainGrid

BrainGrid is an AI product planner designed for software development. It helps you go from a basic idea to a structured plan that AI coding tools can execute. You describe what you want to build—a new feature, a bug fix, or an entire app—and BrainGrid asks clarifying questions to uncover edge cases and hidden complexity. The output is a detailed specification with goals, architecture, and acceptance criteria, all broken down into small, actionable tasks.

The tool stands out by focusing on the planning phase that often gets skipped when using AI coders directly. Instead of a back-and-forth chat that might miss important details, BrainGrid creates a solid foundation. It generates the kind of clear, structured prompts that coding agents need to work reliably. You can then send these tasks to your preferred tool, such as Cursor, Claude Code, or OpenAI Codex, via MCP, CLI, or simple copy-paste, avoiding vendor lock-in.

BrainGrid is ideal for non-technical founders, indie hackers, and developers who use AI assistants but struggle with scaling prototypes into production-ready software. It's useful for planning new features without breaking existing functionality, turning a vague concept into a well-defined project, and ensuring that the final code meets the original requirements. It addresses the common problem of AI-generated code that works in a demo but fails at scale.
