Preuve AI

Every AI validator tells you your idea is brilliant. You know it's lying.

Preuve tells you the truth, with the sources to prove it (Preuve is French for proof). Paste one sentence. In 60 seconds, free, no card:

✅ A viability score and a clear go / no-go verdict
🔗 Every claim linked to its source: the Reddit thread, the funding round, the G2 review
🏢 Real competitors with pricing, funding, and weak spots
📈 Demand signals from Google Trends, Reddit, Quora, and Product Hunt
⚠️ The one risk most likely to kill the idea before you build it

9 out of 10 ideas score below the launch-ready line. Better to know now than after six months of building.

🚀 Founder Report: the full picture
19 sections localized to your market, including a 2-minute Audio Pitch: TAM / SAM / SOM from real data, up to 15 competitors, your first customer and positioning wedge, a go-to-market plan, and 3 pivots built on your idea's actual weak spots.

🧭 Founder Fit: no other validator does this
A separate score for how well YOU fit the idea: founder-side risks with real figures, a "what breaks you first" timeline, and the pivot that fits your situation.

🗣️ Proof of Demand
Real people on Reddit who already described the pain your idea solves. Your first conversations, found for you.

⚡ How it works
10 specialized agents scan 60+ live sources (Crunchbase, Reddit, G2, Product Hunt, Google Trends). A cross-validator fact-checks every claim. If scoring runs disagree, Preuve reruns until the verdict is stable. Powered by Claude Opus 5.5.

👥 Built for founders, indie hackers, and agencies validating client ideas, before or during the MVP.
