AI-powered stress testing for your ideas. Get brutally honest feedback on your startup pitch, product concept, or marketing strategy. Devil’s Advocate is an AI tool that challenges your startup, product, brand, or marketing idea by exposing weak assumptions, failure points, and stronger paths forward.

Hi Product Hunt 👋 I built Devil’s Advocate because I noticed a dangerous pattern: most AI tools are incredibly helpful, but sometimes too agreeable. When you are working on a startup, product, brand, or marketing idea, encouragement is useful — but it can also be dangerous. Sometimes what you really need is someone who says: “Wait. This assumption is weak.” “This market may not care.” “This pricing logic doesn’t hold.” “This idea sounds good, but it may break here.” That’s what Devil’s Advocate does. It stress-tests your idea, exposes weak assumptions, shows possible failure points, and suggests stronger ways to position, validate, or rebuild the concept. It’s designed for founders, designers, marketers, consultants, and creators who want sharper feedback before they invest serious time and money. I’d love your feedback: What kind of ideas would you test with this? And would you prefer a softer critique or a brutally honest one? Thanks for checking it out 🙏

Hi Product Hunt
Tomorrow we re launching Devil s Advocate.
It s an AI tool that stress-tests your startup, product, brand, or marketing idea before the market does.
Most AI tools are designed to help, encourage, and agree with you.
But when you re building something new, agreement is not always what you need.
Sometimes you need a sharper question:
What could kill this idea?
What assumption is too weak?
Why might customers ignore it?
Where could the business model break?
That s what Devil s Advocate is built for.
It challenges ideas, exposes weak points, and helps turn vague concepts into stronger, more realistic plans.
We launch tomorrow on Product Hunt.
I d love your thoughts: would you use an AI that challenges your ideas instead of validating them?
