Overview

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

Preuve tells you the truth. Paste one sentence. 60 seconds later, free, no card:

✅ A 0-to-100 viability score with a clear go / no-go verdict
🔗 Every claim source-linked: click through to 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 risk that breaks the idea before you build it

Nine out of ten ideas score below the launch-ready line. (Preuve is French for proof.)

🚀 Go deeper: the Founder Report ($29)

10x the depth, localized to your market: 15 sections, market sizing from real data (TAM / SAM / SOM), up to 15 competitors, first customer and positioning wedge, a full go-to-market plan, and pivots based on your idea's actual weaknesses (+10 score on avg).

🧭 Founder Fit - the part no other validator has

Preuve scores how well you match the idea, not just the idea itself: a separate fit score, founder-side risks that cite real figures, a "what breaks you first" timeline, and the pivot that fits your situation.

🗣️ Proof of Demand

Preuve scans Reddit for real people who publicly described the pain your idea solves.

⚡ How it works (for the skeptics)

10 specialized agents scan 60+ live sources (Crunchbase, Reddit, G2, Product Hunt, Google Trends): market analyst, competitor scout, community researcher, financial analyst, news scanner, and a cross-validator that fact-checks every claim. When scoring runs disagree, it reruns until the verdict is stable. Runs on Claude Opus 4.8.

👥 Who it's for

First-time and serial founders, indie hackers, solo builders, and agencies validating client ideas. Especially AI-native and vertical B2B SaaS, before or during MVP.

🧰 Beyond the scan

📦 Build with AI Pack: export your analysis as a context pack for Claude, ChatGPT, or Cursor
📡 Radar: monthly rescans with competitor and demand alerts
🎩 Investor Package: founder-built pitch deck, memo, and financial model
🔌 Agent API and MCP: run Preuve from Claude or Cursor

💸 Pricing

Free scan (no card) · Founder Report $29, 14-day guarantee · Monitoring from $19/mo. 6,000+ ideas analyzed. 5-star rated on Trustpilot.

🎁 Relaunch offer: 15% off the Founder Report with code TAAFT. Ends August 15.

Pramima Mar 2, 2026 v@ initial release

I love it. The data is really accurate and it points out things we didn’t even think about. It also correctly identifies competitors we didn’t even know existed.

Nodus Jan 27, 2026 v@ initial release

Game changer. Fast, reliable expert feedback without the awkward asks. Skip the friends and family bias , get real market insights in minutes.

Julio Jan 25, 2026 v@ initial release

So I tested out Test Your Idea, and it actually works pretty well. You put in your idea, wait a minute, and it shows you the stuff you've been missing. Got some decent pivot suggestions that helped me refocus from a tiny niche to something way bigger. Saved me from probably wasting a few months in the wrong direction if you're actually gonna build something, not just daydreaming about it

Larry Thorne Jan 25, 2026 v@ initial release

On top of the large amount of the data that the tool provided, it helped me identify critical shortfalls in my idea, that I had not previously even thought about despite having developing my idea for a good while now. The tool also offered several suggestions on how to pivot my idea to increase the likelihood of success. For me, one of the suggestions required only a minor amount of work, but in turn allowed me to move from targeting a small niche to a large, proven customer base. This, for me, was the most valuable part of the report.

I would recommend "TestYourIdea" for anyone serious about taking the step from an idea to an actual business. I feel like what I paid is incomparable to the potential hours and money saved by making the necessary changes now rather than later.
