Comparison
Preuve AI vs IdeaProof
Both tools validate startup ideas with AI. The difference is where the data comes from and whether you can verify it.
TL;DR: Preuve AI scans 40+ live sources and links every claim to its origin. IdeaProof generates analysis from LLM models without external source verification.

Feature comparison at a glance
The core difference
The fundamental difference: where does the data come from?
Live source scanning
- AI agents search 40+ sources in real-time
- Competitors found on Crunchbase with real funding data
- Demand signals from Reddit, forums, review sites
- Every data point links back to its source
- You can click any claim and verify it yourself
- If a competitor launched last week, we find it
LLM-generated analysis
- AI models from 2024 (Claude 3.5 + GPT-4) generate analysis
- Competitor data comes from model training data
- Claims "89% accuracy" without citing methodology
- No source links - claims are unverifiable
- Analysis quality depends on model knowledge
- Looks comprehensive but can't be fact-checked
The real test
Does the tool ever say no?
A validator that tells every founder their idea is great isn't validating anything. It's a feel-good machine.
~78
average score
AI-generated analysis with no live data to disagree with. High scores feel good but don't mean much.
~50
median score
6 scoring frameworks against 40+ live sources. 90% of ideas score below 70. If your idea scores well, it earned it.
A low score isn't a rejection - it's a fix list. The gap between a 48 and a 72 is usually 2-3 fixable problems.
Fair assessment

Why Preuve AI
What Preuve AI does differently
Live source scanning
40+ sources searched in real-time, not from training data. Crunchbase, Google Trends, Reddit, Product Hunt, G2, and more.
Verifiable claims
Click any data point to see its source. No trust required. Every competitor, funding round, and demand signal links back to where we found it.
Honest scoring
We tell founders when their idea needs work. 90% score below 70. Six scoring frameworks mean the data pushes back when the numbers don't add up.
Investor-ready deliverables
$299 package with pitch deck, investment memo, 18-month financial model, and competitive teardown. Built for due diligence, not just brainstorming.
Interactive dashboard
Shareable link with 13 interactive sections. Filter competitors, drill into market data, and share specific sections with co-founders or investors.
Competitor intelligence
Real competitors with real funding data, real pricing, and real traction. Not a list of names from an LLM's training data.

Fact-checking IdeaProof's marketing claims
“89% accuracy”
IdeaProof cites this on every page - their compare page, feature matrix, and CTAs. We searched ideaproof.io for the methodology behind this number. No source, no study, no explanation of how it was measured. If a startup put an unverifiable accuracy claim in a pitch deck, investors would flag it immediately.
“Real-time Data Sources”
Their feature matrix gives IdeaProof a green checkmark for “Real-time Data Sources.” Their analysis is generated by Claude 3.5 and GPT-4 - both released in 2024, now two generations behind. These models use training data with knowledge cutoffs. LLM inference on outdated models is not the same as querying live APIs.
“$0 per validation / 100% free forever”
Their feature matrix lists “$0 cost per validation” and “100% free forever.” Their pricing page shows three paid plans at EUR 19, EUR 49, and EUR 99. The free tier includes 70 credits.
“Claude 3.5 + GPT-4”
IdeaProof lists these models as a feature. Both were released in 2024 - in AI, that is a generation behind. Preuve AI runs the latest 2026 models. We don't publish which ones to prevent copycats, but every analysis uses the most capable models available at the time of your scan.

FAQ
Common questions about Preuve AI vs IdeaProof
Is IdeaProof accurate?
IdeaProof claims 89% accuracy but doesn't cite the methodology behind this number. Without source links, there's no way to verify individual claims in their reports. Preuve AI takes a different approach - every data point links to its source so you can verify accuracy yourself.
Which tool gives real market data?
Preuve AI pulls from 40+ live sources (Crunchbase, Google Trends, Reddit, Product Hunt, G2) and links every claim to its origin. IdeaProof uses multi-model AI to generate analysis without external data verification. The distinction matters when you need to trust the numbers.
Can I try both tools for free?
Yes. Preuve AI offers a free viability scan (score + risks + 2 competitor previews). IdeaProof offers 70 free credits (approximately 3 validations). Try both and compare the outputs.
What is the best startup validation tool in 2026?
It depends on what you need. If you want evidence-backed analysis with verifiable source links, Preuve AI is the only tool that delivers this. If you want brand identity and marketing assets bundled with validation, IdeaProof offers that at higher tiers.
Does IdeaProof offer investor packages?
As of March 2026, IdeaProof does not offer dedicated investor deliverables. Preuve AI offers a $299 Investor Package with pitch deck, investment memo, 18-month financial model, and competitive teardown.
