Who it’s for
Four friends deciding which startup idea to pursue together.

Four friends, one fair scoreboard.
For four friends deciding which startup idea to pursue together. They argued over ideas without shared criteria. So each person rates every idea on the same four things, on their own, and a sealed second opinion waits until the humans have had their say.

Pick your seat
Four friends share one room and one final scoreboard.
Draft your idea
The other three have drafted theirs. Edit yours, or keep the suggestion.

Review the ideas
Score the business, not the speaker. Each friend submits one rating per idea. Keys 1–5 set the focused row.
Idea scorecard
On stage
Presentation order is randomised, so nobody picks the slot after the strongest pitch.
The council review is sealed
A sample council has already read all four drafts. It stays sealed until every idea has been presented.
A simulation, not the app. The three friends, their ideas and their ratings are sample data, and the council review is a sample written for this page: in the real app five advisor calls, five anonymous peer reviews and a chairman run on my laptop. Nothing leaves your browser.
What it’s for
Four parts, plainly.

By hand, until now
They argued over ideas without shared criteria.
03
What I built
A shared session where friends draft ideas, rate each one on four criteria on their own, and present them in a random order. The human scoreboard is then compared with a sealed AI council review that stays hidden until someone reveals it.

Where it is
Live, for the friends it was built for; public repository (named Startup_war).
Rough edges
The small print.
- The councilThe AI council runs through a worker on my laptop.
- Sharing a roomRooms only sync between devices when a Supabase database is set up; otherwise they stay in one browser.
The council follows the LLM Council method credited in its README.
Honest line: the four criteria, the stage names, the random order and the council’s structure are the app’s own. The friends, their ideas, their ratings and the council’s words are samples.
