DontBuildThis

The core feature drops your idea into a roasting machine powered by a model tuned for blunt, funny criticism. It dissects the pitch the way a skeptical investor might, calling out vague claims and crowded markets. The tone is entertainment, but the substance points at real gaps. No mercy, and no filler.

Rather than a random vibe check, ideas are judged against a rubric covering market, moat, monetization, and similar dimensions. Each factor carries weight, so the final score reflects a structured read on the concept. You get a number that's easier to compare across ideas than a paragraph of opinion.

Each roast ends with a tier label and, for strong ideas, a survivor badge. The site says only around 15% of submissions clear the bar, so a badge becomes a small signal of quality. It's a game mechanic, but it gives the feedback a clear pass or fail shape.

Alongside the roast, the tool returns a damage control section with suggestions such as pivoting, narrowing the audience, or reworking the model. It turns a joke into a concrete to-do list. Higher plans add recovery reports and in-depth trend analysis.

You can make an idea public so others can roast it too, and strong entries land on a leaderboard of ideas that survived. It adds a social layer and lets you see how your concept stacks up against a crowd.

The Free plan gives 3 roasts and 1 recovery report a month. The Monthly plan at $19 unlocks unlimited roasts and reports, and the PRO plan at $49 adds in-depth analysis plus access to partner tools through the FullKit.ai bundle. Payments run through Stripe.
