BrainGrid

About BrainGrid

BrainGrid is an AI app-building platform whose entire pitch is the step most of its competitors skip. Its argument is that tools which jump straight from a prompt to code leave you debugging an application whose intended behaviour was never written down, so BrainGrid writes the specification first, gets your explicit sign-off on it, and only then builds. After building it verifies that the result does what the spec said, then runs the app live and hands over a product you own. The named starting points on the homepage describe the realistic use cases well: build a SaaS product, build an internal tool, ship a feature inside an existing repository, build an AI-powered app, build a marketing site, and — tellingly — rescue a vibe-coded app, which is the situation a lot of teams are actually in after a year of prompt-first building. It works against your own repository rather than only greenfield projects, and it runs on multiple underlying coding agents rather than being tied to one. Collaboration on plans and specs before a build starts is a paid feature, which fits the plan-first model: the review step is the product. Pricing is per seat and credit-metered, and there is a meaningful discount for annual billing.
