Ship a prototype before the spec doc.
Test ideas with real users in hours, not sprints. No design ticket, no engineering pull, no slide deck.
Engineering says 'next quarter.'
You need a validated answer this week. The roadmap doesn't move just because your hypothesis is hot.
Figma is a still image.
Click-through prototypes lie. Real flow exposes real friction. braincell gives you a working URL.
Spec docs are written from guesses.
Write the spec after the prototype, not before. Numbers from real users beat opinions in a Notion doc.
Every capability your buyer asks for.
From doc to URL in 60 minutes
Paste your PRD into the prompt. The agent stands up a working flow before lunch.
Real telemetry
Ask the agent to wire PostHog, Plausible, or custom events into the prototype. Test the funnel you actually care about.
Share with real users
Every prototype deploys to a public URL. Need a closed test? Ask the agent to add auth or a password gate.
Snapshots = perfect A/B history
Variant A and variant B as separate snapshots. Roll back, fork, compare side-by-side.
Common questions.
Reach out at sales@braincell.sh for anything beyond this list.
The output is real working code, not a mock. Engineers can clone the project and continue from where the prototype left off, no rewrite required.
Ready when you are.
