Questions & Answers

As answered by people managing WhittleOS and Comapi.

What makes your product unique?

WhittleOS's answer

It's deliberately kill-biased and it shows its work. Instead of grading an idea you type in and flattering it, WhittleOS can source real candidates from public sources itself, checks that a documented problem sits behind each one, and computes the 0–100 score in code from a fixed weighted rubric — the model rates each area but never sets the total. When a market is genuinely weak it returns nothing, honestly, rather than a feel-good score. Every problem it cites links to the page it was read on.

Why should a person choose your product over its competitors?

WhittleOS's answer

Most idea validators grade an idea you bring and skew encouraging. WhittleOS does two things they don't: it sources the ideas itself across real markets, and it's built to find the reason an idea should die early. The verdict is bound to your founder profile — the same idea reads differently for a solo founder than a funded team — and it's auditable: you can see which check produced it. It won't claim accuracy no one can prove; it shows the evidence instead.

How would you describe the primary audience of your product?

WhittleOS's answer

Solo and indie founders — technical or not — who want a blunt, evidence-backed decision before spending months building. It assumes one person with limited time and budget, a no-call sales style, and a subscription-shaped product. Not for accelerators, agencies, or teams wanting a pitch-deck generator.

What's the story behind your product?

WhittleOS's answer

It started from a simple observation: most idea-validation tools are feel-good machines that tell founders what they want to hear, and a solo founder can lose months building on that. WhittleOS was built to be the opposite — a decision engine willing to say no, that sources its own evidence and computes the verdict in code so it can't talk itself into a pass.

Which are the primary technologies used for building your product?

WhittleOS's answer

Next.js and TypeScript on Vercel, with a Postgres database. The analysis runs on large language models (Claude and GPT) behind a fixed rubric and decision matrix — the models supply the ratings and evidence, but the weighting, scoring and gate are code.
