Not just a score.
A strategy.
IdeaRoast doesn't just tell you if your idea is good or bad. It dissects where your idea is strong, where it's weak, and what to do about it — so you only build what's worth building.
Building is easier than ever. Succeeding isn't.
We're living in an incredible moment. Tools like Replit, Lovable, and Bolt have made it possible for anyoneto go from idea to working product with just a prompt. You don't need to be a developer. You don't need funding. The barrier to building has never been lower — and that's amazing.
But here's what nobody talks about: most of those products never find users. People build fast, launch fast — and then face silence. No signups, no traction, no customers. Not because the product was bad, but because the idea wasn't validated.
That's why we built IdeaRoast. Our mission is to make idea validation as easy and accessible as building itself. We help you identify your idea's strengths, expose its weaknesses, and tell you exactly what to do next — whether that's pivot, refine, or go all in.
Five steps. Sixty seconds.
In plain language, tell us what you want to build. No pitch deck needed — just the core concept, who it's for, and what problem it solves.
Our AI searches the live web for competitors, funding rounds, market trends, and timing signals relevant to your specific idea.
Your idea is scored 0–100 across 8 research-backed criteria. You'll see exactly where it's strong, where it's weak, and why.
Strengths, risks, market intel, and a brutally honest recommendation — plus a two-line roast that doesn't pull punches.
Score 40+? Generate a platform-optimized MVP prompt. Paste it into Replit or Lovable and start shipping — with confidence.

100 points. 8 criteria. Zero fluff.
Every criterion is weighted based on why startups actually fail — not theory, but data from CB Insights, Y Combinator, and Bill Gross's research across 200+ companies.
Is there proven, measurable demand? Based on CB Insights finding that 42% of startups fail from no market need.
Is the market ready NOW? Bill Gross showed timing is the #1 success factor across 200+ companies.
Y Combinator's 'hair on fire' test — is this a painkiller or a vitamin?
Does the product get better or cheaper as more people use it? Network effects matter.
Peter Thiel's monopoly test — if Google copied this tomorrow, would users still pick you?
Can you explain who pays, how much, and why in one sentence?
Can you reach your first 1,000 users for under $10K with a clear channel?
Can 2-3 engineers ship an MVP in under 6 months with today's tech?
Your roast becomes a build-ready MVP spec
When your idea scores 40 or above, IdeaRoast generates a platform-optimized prompt you can paste directly into Replit or Lovable. Not a vague description — a real spec with database schemas, feature priorities, user flows, and design direction.
Technical spec with DB schema, feature list, user stories, and stack recommendations.
Design-focused brief with user flows, aesthetic references, and interaction patterns.
Weak moat? The spec addresses it. Strong demand? The spec leads with it.
