Choose Plan

Score your idea out of 100, sharpen it with Smart Pivots, and turn the research into an MVP kit

Check the market before you bet six months

  • Put ten AI agents on your idea: they research it across 60+ live sources, from Crunchbase and Google Trends to Reddit, Product Hunt, and G2
  • Open the source behind each claim in a report of up to 20 sections, from a funding round to a pricing page or forum thread
  • See up to 15 competitors with funding, pricing, and a threat level on each, and read how to beat them
  • Get a viability score out of 100 from a strict grader, and see if your idea clears the launch-ready bar
Check the market before you bet six months

Spot a sharper version hiding in your idea

  • See what’s limiting your score in one sentence drawn from your report’s evidence
  • Compare your Smart Pivots, highest impact first: each shows its expected gain, effort, what changes, what you keep, the evidence, and the trade-off
  • Apply one and see how far your idea can climb: a new deep report tests that version and rescores it
  • Run quick starter scans on new angles before you commit a deep report to one
Spot a sharper version hiding in your idea

Hand your coding agent a plan backed by research

  • Download a kit made from your report: an AGENTS.md, a five-milestone PLAN.md, and docs on your buyers, scope, competitors, pricing, and risks
  • Pick your coding agent: open the kit in Claude Code, Cursor, Codex, or Antigravity and work through PLAN.md one milestone at a time
  • Or start in Lovable in one click from the same report, and bring your research into other AI tools with MCP access
  • Map out your first 100 customers with a launch plan drawn from your report

Turn validation into paid agency work (available in Tier 4)

  • Screen prospects before the first call: ideas sent through your branded intake form land in one dashboard with a score and a fit label, top leads first
  • Choose what each client sees: hide any section of a report, and your own notes and internal analysis never reach the client link
  • Show your name, logo, colors, and font on client links and the intake form, export reports as Markdown or JSON, and use them under a commercial license

Why I built Preuve AI

I spent 5 years in B2B growth marketing. Over and over, founders asked me to fix the marketing on a product nobody had asked for. The marketing wasn't the problem. Nobody had pressure-tested the idea before it got built.

Now anyone can build an app in a weekend with Claude Code or Cursor, so that mistake got faster, not rarer. I built Preuve AI so the pressure test happens first. Ten AI agents pull live data from Crunchbase, Reddit, Google Trends, Product Hunt, G2 and dozens more, and the report links its claims to their sources. It is strict on purpose: in our July 2026 benchmark, only 17.5% of 6,000+ anonymized ideas cleared the launch-ready bar. A weak verdict alone helps nobody, so every report also shows what to change, and hands your coding agent a plan once the idea holds up.

I'm building this alone from Paris, bootstrapped, to the standard I'd want before betting my own next six months: real data, a source for each claim, and a verdict that does not flatter.
