Sanity-Check

The cure for AI sycophancy. Submit your precious idea and receive a brutally honest but genuinely insightful critique. No cheerleading. No sugar-coating. Just the truth.

Everybody's got an idea: yours is almost certainly terrible. Let's make sure.

Sanity Check is an AI-powered consultant and confidant that delivers brutally honest, structured assessments of whatever you're cooking up — business plans, startup pitches, hot takes, life decisions, investment theses, or creative projects. Think of it as a consultancy review written by someone who genuinely doesn't care about your feelings.

Your friends, family, and colleagues will lie to you. Your favorite chatbot will lie to you. We won't.

HOW IT WORKS

Type in your idea with a title, description, and category. Tap submit. Within seconds, you'll receive a multi-section critique covering strengths, weaknesses, market reality, and more - capped off with a verdict and a score out of 10.

THREE VERDICTS

DEMOLISHED — Your idea has been laid to rest. SHAKY — Proceed with extreme caution. SURVIVED — Against all odds, this might not be terrible.

Every critique ends with a sharp one-liner summary you'll either frame on your wall or try to forget.

SHARE THE DAMAGE

Got demolished? Share it. Survived? Prove it. Every critique generates a shareable link so your friends, co-founders, or enemies can see exactly how your idea held up. Public critique pages live at sanity-check.app — no app download required to view.

THE GRAVEYARD OF IDEAS

Every critique you've ever received lives in the Graveyard tab - a monument to your folly. It's your personal archive of ideas that have been tested, judged, and laid to rest. Revisit old critiques, track your scores over time, and see if your ideas have improved with the passage of time (they have not).

PRICING

• 1 free trial critique — no credit card, no commitment, no quarter. • Pro: $4.99/month for 30 critiques • Booster Pack: $1.99 for 15 extra critiques (never expire)

WHY SANITY CHECK?

Most AI tools tell you what you want to hear. Sanity Check tells you what you need to hear. It's the friend who actually says "that's a terrible idea" before you quit your job to open a blockchain restaurant. Except this friend has read every business book, studied every market failure, and has zero emotional investment in your ego.

Whether you're a founder pressure-testing a pitch, a creative seeking honest feedback, or just someone who wants to know if their hot take holds up — Sanity Check is the reality check you didn't know you needed.
