The real test
A rank class is not a benchmark
Gaplyze grades each dimension into a named tier, from Pinnacle down to Negligible. The vocabulary is clean, but there is no published distribution telling you how many ideas land where.
Preuve AI · 6,500+ ideas
55
median score across 13 industries
Every score is graded against 6,500+ ideas analyzed since 2026, and only 18.3% earn a go verdict at 70 or above, so a strong score here is one most ideas never reach.

tier shown in their homepage sample
Dimensions come back as Superior, Elevated, Robust, Steady, and so on. Without a distribution behind those words, there is no public way to tell whether Elevated is rare or the default.

The gap between a 48 and a 72 on Preuve is usually 2-3 fixable things, and you can see exactly where your idea sits in the distribution.
Fair assessment
What Gaplyze does well
Once the decision is made, the planning layer does real work. That deserves saying plainly.
Fourteen blueprints
Foundation, UX/UI, GTM, Business Model, Technical, Retention, Monetization, Marketplace, and more, each generated from the strategic path you locked instead of a blank template.
Prompt packs for coding agents
The whole decision dossier compiles into a brief for Claude Code, Codex, Cursor, Windsurf, or Aider, so the first commit respects the wedge you committed to.
Evidence Ledger
Market Intelligence findings carry a source URL, a timestamp, and a confidence band. That is a genuinely rigorous way to hand evidence to a reader who will check it.
What Preuve AI does differently
The scan comes first
The score is produced by 10 parallel agents reading 50+ live sources at scan time, not by grading the paragraph you typed in. Free, private, under a minute.
6,500-idea benchmark
Your score is graded against 6,500+ ideas analyzed since 2026 across 13 industries. Median is 55 and only 18.3% earn a go, so the number has context.
Verifiable claims
Click any data point to see its source. Every competitor, funding round, and demand signal links back to where it was found.
3 pivots, not a plan for a dead idea
When the verdict is weak, the report hands you 3 pivots based on competitive gaps and market signals you can test next.
Investor deliverables
$499 package with pitch deck, investment memo, 18-month financial model, and competitive teardown, founder-built and reviewed for due diligence.
One-time, not a meter
$29 buys the full 15-section report and it stays yours. No monthly credits to forfeit, no plan to keep paying for between decisions.
Verdict in one minute
Who should use which tool
These two barely overlap once you name the question. One decides whether to build. The other plans the build.
Best for most founders
Choose Preuve AI if
- The open question is still build, pivot, or kill
- You want the score to come from live sources, not your own framing
- You would rather pay $29 once than $240 a year
- You want the idea kept private while you test it
→ Most founders start here
Choose Gaplyze if
- You have already decided to build and need the plan generated
- You want 14 blueprints and a sequenced execution roadmap
- You brief coding agents and want prompt packs made for them
- You run a portfolio and will use the subscription every month
→ Best once the decision is made

Three Gaplyze claims worth a closer look
Every quote below is from gaplyze.com or brainstron.ai, checked on July 28, 2026.
Grades your input
“Not a vibes-based number, a defensible signal.”
Our finding
The same FAQ answer says every score “traces back to the inputs you supplied.” So the framework is consistent, which is real, but the signal it grades is your description. Live evidence enters later, in the paid Market Intelligence step.
Count varies
“8-dimension Idea Score”
Our finding
The homepage contradicts itself: its Idea Score section names six (demand, wedge, distribution, economics, defensibility, founder fit) while a scoring widget on the same page shows eight. A guide page lists a third, different set of eight. Three definitions, one score.
Public by default
“Is there a free plan to try first?”
Our finding
There is, and it is generous. Further down the same FAQ: “On the free plan, generated content has public visibility by default.” A deliberate trade-off on their side, but worth reading before you paste in an idea you have not told anyone about.

FAQ
Common questions about Preuve AI vs Gaplyze
What is the difference between Gaplyze and Preuve AI?
Gaplyze is a Product Intelligence OS: it scores an idea, maps three strategic paths, generates 14 blueprints, sequences an execution roadmap, and exports prompt packs for AI coding agents. Preuve AI is a validation report: 10 parallel agents scan 50+ live sources, every claim links back to its origin, and the score is graded against 6,500+ ideas already analyzed. The practical split is planning versus evidence, and rented versus owned. Gaplyze starts at $240/yr on monthly credits; the Preuve Founder Report is $29 once, after a free scan.
How much does Gaplyze cost?
Three plans as of July 2026: Free, Pro at $25/mo ($20/mo billed yearly, or $240/yr), and Plus at $100/mo ($80/mo billed yearly, or $960/yr). Everything runs on a monthly credit allowance. Gaplyze's FAQ states that unused credits do not roll over and are forfeited, that all subscription charges are non-refundable, and that there is no proration when you cancel. Preuve AI charges $29 one-time for the Founder Report, with a free scan before it and no subscription.
Can I try Gaplyze for free?
Yes, with one condition worth knowing. Gaplyze's free plan includes a monthly credit allowance, the Idea Score, the Strategy Map, and the Foundation Blueprint with no card required. Its FAQ also says that on the free plan, generated content has public visibility by default, because Public Ideas is the community contribution surface. Preuve AI's free Reality Check runs privately on your real idea in under a minute and returns a score, top risks, and 2 competitor previews.
Does the Gaplyze Idea Score come from live market data?
Not directly. Gaplyze's FAQ says every score "traces back to the inputs you supplied", so the Idea Score grades the framing you typed in against a fixed set of commercial-viability dimensions. Live signals do exist elsewhere in the product: the idea generator reads Google Trends, Reddit, Product Hunt, Hacker News, VC funding, G2/Capterra, and X, and the paid Market Intelligence step keeps an Evidence Ledger with source URLs, timestamps, and confidence bands. Preuve AI puts the live scan first: the score itself is produced by 50+ sources read at scan time.
Which tool is better for raising money?
Both ship an investor artifact, and they are different artifacts. Gaplyze exports an Investor-Ready memo (PDF and Markdown) assembled from your scored idea, chosen path, market intelligence, blueprints, and roadmap. Preuve AI sells a $499 Investor Package with a pitch deck, investment memo, 18-month financial model, and competitive teardown, founder-built and reviewed from your report. If you need a plan document, Gaplyze. If you need due-diligence deliverables, Preuve.
Can I use Gaplyze and Preuve AI together?
Yes, and the order matters. Run the free Preuve scan first so the go or no-go call comes from 50+ live sources rather than from your own description, then take a validated idea into Gaplyze for the strategy paths, blueprints, roadmap, and coding-agent prompt packs. Paying $240 a year to plan an idea a $0 scan would have killed is the expensive way round.
