What Is Preuve AI?

This Preuve AI review examines an AI research tool that scores a startup idea out of 100 and backs each finding with a source. Preuve AI behaves like a small analyst team, not a chatbot. You give it an idea, and it returns demand data, competitor data, pricing data, and a viability score.

According to official documentation on the Preuve AI site, ten AI agents pull live data from 60+ sources including Crunchbase, Google Trends, Reddit, Product Hunt, and G2. The report opens the underlying page behind every claim. That makes checking a funding round or forum thread a short task instead of a blind trust exercise.

Preuve AI was built by Vincent Forat, a B2B growth marketer in Paris. He states that in a July 2026 benchmark, only 17.5% of over 6,000 anonymized ideas cleared the launch-ready bar. That strict rubric matters because the tool is designed to catch weak ideas before you commit months to building them.

The tool is not an AI meeting coach that transcribes calls. Preuve AI also does not write your launch copy, so pair it later with a content generation tool once the idea passes.

Key Features That Matter

10 AI Agents Pulling From 60+ Live Sources

Preuve AI deploys ten research agents instead of one model guessing. Vendor screenshots show source links attached to individual claims. You click from a claim to the original Crunchbase profile, pricing page, or Reddit thread.

Deep Report With Up to 20 Sections

A deep report covers demand, competitors, pricing, risks, and launch planning in up to 20 sections. The output works as an audit trail, not a skim page. One AppSumo buyer, Kivo U., says in French that the tool adds structure and clarity to an idea rather than returning a binary answer.

Competitor Map With Funding and Threat Levels

You get up to 15 competitors, each with funding, pricing, and a threat level. This matters when you need to price before you build. If you already have messy competitor spreadsheets, a data scraper like Texau can clean them before you add the findings.

Smart Pivots

Smart Pivots show expected gain, effort, what changes, what you keep, the evidence, and the trade-off. You can run quick starter scans on new angles before spending a deep report. This is useful when your first viability score falls below the launch-ready bar.

MVP Kit for Coding Agents

The tool exports AGENTS.md, PLAN.md, and documents covering buyers, scope, competitors, pricing, and risks. You can open the kit in Claude Code, Cursor, Codex, or Antigravity. You can also connect the research to Claude, ChatGPT, and other tools through MCP access.

Once research says go, you may also want to secure a matching domain.

First 100 Customers Launch Plan

Preuve AI can draw a launch plan from the same report. The plan maps early customer channels before you spend on product. That turns validation into an actionable acquisition starting point.

White Label and Agency Mode

Tier 4 adds a branded client intake form, client share controls, white labeling, and a commercial license. Agencies can screen prospects with a score and fit label before the first call. You choose which report sections clients can see.

Pricing Tiers (starts $59)

The $59 Tier 1 gives you 3 deep reports and 25 starter scans. Tier 2 raises that to 10 deep reports and 100 starter scans. Tier 3 offers 25 deep reports and 200 starter scans.

Tier 4 includes 80 deep reports, unlimited starter scans, white label, and a commercial license. All plans are lifetime purchases covered by AppSumo's We Got Your Back guarantee.

Pros and Cons

Pros

• Deep reports cite live sources for every major claim.
• Up to 20 sections cover demand, pricing, competitors, risks, and launch plan.
• Smart Pivots show expected gain versus effort before you commit.
• MVP kit exports AGENTS.md and PLAN.md into AI coding tools.
• One time pricing starts at $59, no monthly subscription.
• Strict scoring fails weak ideas before you waste build time.
• Tier 4 adds white label features for paid client work.

Cons

• Tier 1 only allows three deep reports and one Smart Pivot.
• No subscription means future feature updates may require a repurchase.
• Public data sources miss private market, sales, and insider data.
• Output is report based, not a live chat for follow on questions.
• Lower tiers lack white label and commercial license for client delivery.
• AppSumo listing shows only 8 reviews, so external feedback is thin.

Who Should Use Preuve AI?

Solo founders who want a strict viability check

If you are about to spend weekends coding, Preuve AI gives you a score and evidence before you write a line. You learn if demand exists and what competitors charge. That alone can stop a bad six month build.

Agencies selling validation as a service

Tier 4 is built for client work. You can screen prospects with a branded intake form, hide specific sections, and deliver white label reports. The tool becomes a paid deliverable, not just an internal research aid.

Indie hackers using AI coding agents

If you work in Claude Code, Cursor, Codex, or Lovable, the MVP kit drops research directly into your workflow. You can follow PLAN.md milestones instead of guessing what to build first. The research and build loop stays connected.

Skip Preuve AI if you need unlimited deep reports every month, want private market data, or prefer a live AI chat for follow up questions. If you only need a general assistant, a tool like Geminiprime AI covers a different use case.

Alternatives to Consider

ChatGPT handles open ended brainstorming and general research. It is flexible but does not package a scored, sourced report with competitor threat maps and an MVP kit.

Perplexity returns fast cited answers for direct questions. It is strong for search but not built for white label client reports or Smart Pivot suggestions.

VentureKit targets similar founder research workflows. Preuve AI currently competes on its lower lifetime entry price and its AppSumo refund window.

Final Verdict

Preuve AI's strongest advantage is that it forces your idea to face sourced evidence, not vibes. The $59 entry price is low for a validation report that can stop a bad six month build. The tier limits are real, but the 60 day AppSumo refund window gives you room to test a deep report before committing further.

If you are a founder or an agency that sells validation, Preuve AI is an easy lifetime tool to justify.

Frequently Asked Questions

Does Preuve AI have a free plan?

No. Preuve AI does not have a free plan. The AppSumo deal is refundable for 60 days, so you can test a deep report and request a refund if it underperforms.

How does Preuve AI compare to ChatGPT?

ChatGPT is general and conversational. Preuve AI runs ten research agents, returns a scored report with citations and a competitor map, and generates an MVP kit. ChatGPT does not produce a strict viability score with source labels in the same way.

Can I cancel anytime?

This is a lifetime purchase, not a subscription. You pay once and there is nothing to cancel. You can request a refund within 60 days through AppSumo.

Is Preuve AI worth the price?

For a founder testing one idea, $59 is cheap insurance before months of build work. For agencies, the Tier 4 price makes sense if you deliver multiple client validation reports. The right tier depends on how many deep reports you need.

How does Preuve AI review my startup idea and score it?

The tool sends ten AI agents across 60+ live sources to collect demand, competitor, pricing, and risk data. It grades the idea against a launch-ready bar and adds a source link for each claim, so you can verify the score.
