Preuve AI Review (2026): Real Feedback, Pricing, Pros and Cons

I built Preuve AI (formerly TestYourIdea). So yes, this review is biased. I'm telling you that upfront.

What I can do is show you exactly what's inside, share what real users say (with sources you can check yourself), and be honest about where it falls short. You decide whether Verdict or Founder is worth paying for.

What is Preuve AI? Preuve AI is a startup validation tool that scans 40+ live data sources and generates a viability report with a 0-100 score, sourced competitor data, market sizing (TAM/SAM/SOM), risk assessment, and a fix playbook. Every claim in the report links to a verifiable source.

What's Inside a Preuve AI Report?

I built the pipeline to pull from 40+ live data sources: Crunchbase, Google Trends, Reddit, Product Hunt, G2, Capterra, Hacker News, and more. A free scan takes about 60 seconds. The full sourced deep scan takes around 5 minutes.

Here's what you get:

Viability score (0-100)

One number that summarizes market readiness. I designed the Preuve AI scoring to be skeptical. More than 4,000 ideas are now in the benchmark set, and 81.7% score below 70. If your idea scores well, it earned it.

Competitor landscape

Real company names, real pricing, real funding data. Not "you may face competition from similar startups." I wanted the report to show you exactly who's in the market, with links to their sites.

Market sizing (TAM/SAM/SOM)

With sources. If the report says your market is $1.5B, you can click through and see where that number came from. I wrote a full guide on how TAM SAM SOM works.

Demand signals

Search volume trends, Reddit threads, community discussions. Is anyone looking for what you're building? This is where Preuve AI differs from tools that guess demand. I pull real signals, not predictions.

Risk assessment

Specific blockers ranked by severity. Not generic warnings. Something like "Easy to copy (6.4/10)" with an explanation of why and what to do about it.

Fix playbook (paid only)

Step-by-step actions for every blocker. This is the main reason people upgrade from the free scan.

Niche and Pivot Coach

Same feature, two modes. Niche Coach refines your positioning within your market. Pivot Coach suggests alternative angles with projected score impact. Free users get 1 iteration with limited data. Paid reports guarantee 3 full iterations. 67% of founders who use it see their score go up.

Why I Built It This Way

Every number links to a source

This was the first design decision I made and the one I'm most stubborn about.

If the report says "CPC is high" or "competitor raised $2M," you can click through to the source. Google Trends chart. Crunchbase profile. Reddit thread. Product Hunt page.

I did this because the main failure mode of validation isn't missing data. It's building on assumptions you didn't notice were assumptions. Most validation tools run your idea through an LLM and return confident-sounding analysis. The problem: LLMs hallucinate. They invent competitor names, fabricate market sizes, and generate pricing that doesn't exist. You can't verify what isn't real.

I made the scoring skeptical on purpose

A good validator should say "not ready" most of the time. If it tells every founder their idea is great, it's a marketing funnel pretending to be a research tool.

Preuve AI Reviews From Real Users

I could write marketing copy all day. What matters more is what people say when I'm not in the room. These are Trustpilot reviews, Product Hunt reviews, and direct messages I received from users.

Trustpilot and direct feedback

4 reviewsRead all reviews

"I do not regret any cent spent. Much different from ChatGPT or Claude. I keep coming back to my report."

Michal found the tool on Betalist. What caught my attention: he specifically called out the difference from ChatGPT output. His full review mentions the competitor section and the one-time pricing as reasons he paid.

"The data are on point and the recommendations are accurate. I even discovered a copycat of my idea that launched weeks ago!"

This is the reaction I hear most often. Founders don't know what's already out there. The report surfaces competitors they never would have found on their own.

"I tried a lot of market search and validation tools. This is the best in its category."

Direct messages I received

"Your SaaS helped me structure my fundraising materials. The investor panel responded strongly, and the project moved forward thanks to the clarity your tool gave me."

Kapriel told me he "could have paid more." He used the competitor and market sizing sections to prep his fundraising deck. I didn't build the tool for that use case, but founders keep using it that way.

"The tool helped me confirm key hypotheses and gave me actionable input for my post-MVP roadmap."

This is the use case I didn't expect. Jacob wasn't pre-launch. He was post-MVP and used the report to pressure-test assumptions he'd already built on. More founders do this than I anticipated.

"Fast, reliable feedback without awkward asks. Skip friends-and-family bias and get real market insights in minutes."

This one resonates with me personally. Asking friends "what do you think of my idea?" gets polite lies. I built the tool to give the answer your friends won't.

Why I Priced It This Way

The core validation offers are one-time purchases because most founders are making a specific build-or-pivot decision, not shopping for another SaaS seat. Verdict exists for founders who want the full sourced analysis without pivots. Founder is the higher-conviction buy if you want help improving the idea, not just judging it.

Free vs paid: what's the difference?

Who I Built It For

• 1.Solo founders choosing what to build next. You have 2-3 ideas and limited time. The report tells you which one has the best market signal, with evidence you can verify.
• 2.Indie hackers comparing ideas fast. Instead of 10 hours of manual Google Trends, Reddit, and competitor research, you get a structured deep scan in under 5 minutes.
• 3.Agencies qualifying startup leads. I built a white-label widget that embeds on your site. Founders get a free analysis, you get a pre-qualified lead with a score.
• 4.Pre-seed founders preparing for investor conversations. The market sizing and competitor sections give you numbers you can defend in a pitch. With sources.

Is Preuve AI Worth Paying For?

Pay when you're choosing between ideas and need a tiebreaker with real data. Pay when you want competitor names, pricing, and weaknesses you didn't know existed. Pay when you need numbers you can put in a deck without making them up. If you just want the full sourced analysis, Verdict at $14.99 is the cheaper entry point. If you want pivots and unlimited Starter Scans, Founder at $29 is the better buy. If you're earlier in the process, start with my step-by-step validation guide, then come back and run a scan.

When You Shouldn't Pay

• ✗If you're not willing to talk to customers after. I built a research tool, not a replacement for customer conversations. The report sharpens your questions. You still need to ask them.
• ✗If you want certainty. No tool can guarantee your idea will work. Mine included. It shows you what the data says and where the risks are. That's it.
• ✗If you're just browsing. The free tier handles that fine. Save $29 for when you're actually deciding what to build next.

Where It Falls Short

I know what's wrong with my own product. Here's my honest list:

• ✗Niche markets get thinner data. If your idea targets a hyper-specific vertical with minimal online presence, my sources surface less. The report still runs, but the competitor section will be lighter. I'm working on this.
• ✗No unlimited plan. If you're testing 20+ ideas a month, the per-report cost adds up even with packs. I chose this model because the API costs are real, but I know it limits serial testers.
• ✗No integrations. No Notion export, no API, no Zapier hooks. You get a shareable link. I know people want more here. It's on the roadmap, but not shipped yet.
• ✗You still need to do the work. The report finds problems and gives you fixes. But you're the one who has to execute. I built a research tool, not a magic wand.

What I Think I Got Right

• ✓Sourced data you can verify. Every key number links to where it came from. Click through. Check it yourself. I haven't seen another validation tool do this consistently.
• ✓Fast. A full Preuve AI deep scan takes under 5 minutes across 40+ sources. The manual equivalent takes hours.
• ✓Honest scoring. Only 18.3% of ideas earn a go verdict. I didn't build the tool to inflate results.
• ✓Iterate without paying again. 3 pivot coaching sessions included per paid report. Most founders find their angle in 2-3 tries.
• ✓Multi-language. Full support for 7 languages including Arabic with RTL. I built this for founders everywhere, not just English speakers.
