Strengths, limits and who it suits, in full
Strengths
- One-time pricing Founder products are single payments with no subscription, and Sentinel does not renew or charge after three months.
- Claims link to sources The vendor says sourced claims link back to their source and estimates are labelled as estimates.
- Free first check The Reality Check gives a score, market size and two competitor previews for 2 scans with no payment.
- Reachable from AI chat A remote MCP server and an HTTP API let Claude, Cursor, Codex or ChatGPT start scans on the same account.
Limits
- Score method is closed Factor weights, thresholds and agent prompts are unpublished, and the vendor says the score is a snapshot, not a guarantee.
- Narrow free tier The free check is limited to 2 scans, each viewable for 7 days, with 2 competitor previews and no pivots.
- Narrow refund The 14-day guarantee is a rerun first, once per customer, and not after Build with AI or an export; Lifetime plans and the Investor Package are excluded.
- English-first, no legal or financial advice The vendor lists legal or financial advice, logos and brand kits and ad copy as out of scope.
- Official pages differ The terms list the top 5 competitors in the free check, the pricing page says 2 previews, and the pricing table shows no guarantee for Lifetime while the terms allow a rerun.
Who it suits
- First-time founders choosing between ideas Unlimited Starter Scans with a Founder Report let you pre-screen several ideas before a full report.
- Vibe coders and solo builders Build with AI hands the competitors, go-to-market and plan to a coding agent such as Claude Code or Cursor.
- Founders preparing to raise The Investor-Ready Package adds a deck, memo and financial model, built from your report and reviewed by the founder.
- Not for agencies serving clients on Lifetime The terms limit Lifetime plans to your own ideas and point client work to a Consultants plan or the API.
- Not for people who need legal or financial advice the reports are AI-generated research, and the vendor lists legal and financial advice as out of scope.
How much does Preuve AI cost?
Prices confirmed · checked
Regional prices: Prices are in US dollars on the pricing page; taxes may be added where required and payments run through Stripe.
Every founder product is a one-time payment, and the only recurring plan the vendor lists is a program for agencies and accelerators on request. The 21-section report and the included Sentinel apply to Founder Reports bought from 1 October 2026; the earlier $29 Founder Report has 19 sections and no Sentinel. Each Founder purchase also adds 200 bonus credits, which never expire and pay for extras such as extra pivots; credit purchases are final. Regional offers exist for some countries and are not covered here. Third-party sites still quote a $29 report and a $19 monthly Radar Pro; the vendor says these are no longer current.

How far does it go?
- Testing several ideasFive separate Founder Reports cost $295, against $199 for the 5-Report Pack ($39.80 each). Lifetime Pro at $499 equals 8.5 single reports at $59, so it pays back after the ninth full report, or after the thirteenth against pack pricing. It gives 5 deep scans a month, up to 60 a year, without Sentinel. Arithmetic on published figures, not a statement by Preuve AI.

Key features
| Feature | What it does | Watch out |
|---|---|---|
| Viability score: 0-100 across six factors (market size, demand, competition, moat, business model, regulatory and execution risk), with a verdict at 40 and 70 (how-it-works page) | — | |
| Evidence trail: ten agents query 60+ live sources such as Crunchbase, Reddit, Product Hunt and Google Trends, and sourced claims link to the source while estimates are labelled (agent reference) | — | |
| Founder Report: up to 15 competitors, sourced TAM/SAM/SOM, scored risks, 3 pivots, pre-mortem, first-100-customers plan and a business plan PDF (pricing page) | — | |
| Sentinel: re-runs one idea at day 30, 60 and 90 and emails what changed, new competitors first; included with reports bought from 1 Oct 2026 (terms) | Reruns the full analysis of one idea at 30, 60 and 90 days and keeps every run as a dated version you can open and export. | You choose one idea to track and the choice is final; it must be activated within 3 months of purchase, and reports on Lifetime plans do not include it. |
| MCP server and Agent API: run scans from Claude, Cursor, Codex or ChatGPT; a starter scan is free, a deep scan uses the paid quota (agent reference) | — | |
| Build with AI: turns the report into a build kit for coding agents or a one-click handoff to Lovable (terms, pricing page) | — | |
| Score scale | Zero to 100, cut at 40 and 70: 0-39 no-go, 40-69 conditional, 70+ go. In the July 2026 benchmark of 6,000+ ideas the median was 54 and 17.5% reached 70. | The weights, thresholds and prompts are unpublished and the vendor calls the numbers model assessments, so the score cannot be reproduced independently. |
| Smart pivots | A paid report carries up to 3 pivots on the same idea, ranked by how much they move the score. | Extra pivots beyond the included ones cost 100 credits on some plans, and a delivered pivot is never refunded. |
What does the $59 report add to the free check?
The pricing page splits the product cleanly. The free Reality Check returns a score, a market-size read, two competitor previews and the main blockers. The Founder Report is where the evidence arrives: up to 15 competitors with enriched data, a sourced TAM/SAM/SOM, demand signals, scored risks with three pivots, a go-to-market plan and a business plan PDF. Unlimited Starter Scans let you pre-screen other ideas at no extra cost, and the agent reference says reports bought from 1 October 2026 carry 21 sections plus three months of Sentinel re-scans.
One wording difference matters before you rely on the free tier: the terms describe the free check as showing the top 5 competitors, while the pricing page and the vendor reference say 2 previews. This profile uses the pricing page figure.
How much weight should the score carry?
The how-it-works page says ten agents read 60+ live sources, cross-check each other and score the idea on six factors, but the weights, thresholds and prompts are not published. Preuve AI states the score rates the idea and its market, not the founder, and is a snapshot rather than a guarantee. Its own July 2026 benchmark puts the median at 54 and only 17.5% of ideas at 70 or above, and the vendor stresses these are model assessments, not startup outcomes.
The terms add that reports are AI-generated, may contain errors or outdated information, and that links should be verified independently. Treat a report as a structured research brief to check, not as a verdict. We did not run a scan, so how well it holds up on a given idea is untested here.
Which purchase fits how many ideas you will test?
All founder products are one-time payments. A single idea fits the $59 report; testing a handful favours the packs, where the fifth report costs $39.80. Lifetime Pro only pays back for people who will run roughly a dozen or more full reports, and it comes without Sentinel. Agencies and consultants running client work are pointed to a separate Consultants plan rather than Lifetime.
How could you check Preuve AI before paying?
Proposed evaluation · not performed yet
Check what the free Reality Check returns for an invented idea, using no confidential idea of your own.
- Create a free account and note how many scans the account shows.
- Paste one paragraph for a made-up idea: a booking tool that fills last-minute cancellations for independent physiotherapists, paid by monthly subscription.
- Record the score, the verdict band, the market-size read and how many competitors are shown, then compare that count with the 2 previews on the pricing page and the top 5 in the terms.
- Open two competitor or demand links in the result and note whether each one leads to a live page that supports the claim.
- Check the free report is still viewable after 7 days.
Accept if the shown competitors match the pricing page and the opened links support the claims. Reject if sourced claims have no working link. No result is recorded here.

Frequently asked questions
Is Preuve AI free?
The Reality Check is free: a 0-100 viability score with a verdict, a market-size overview, two competitor previews and the main blockers. It is limited to 2 scans per account in most countries, and each free report can be viewed for 7 days. The full Founder Report, pivots, go-to-market plan and business plan PDF are paid.
How much does a Preuve AI report cost, and is there a subscription?
A Founder Report is $59 as a one-time payment, with packs of 2 for $89 and 5 for $199. There is no subscription for founders; Sentinel re-scans run for three months and then stop without charging. Lifetime Pro is $499 and Lifetime Business $999, both one-time. Older $29 and $19 a month figures on other sites are no longer current, according to the vendor.
Can I get a refund on a Preuve AI report?
The 14-day guarantee works by email: Preuve AI reruns the report first and refunds it if it is still not useful. It applies once per customer and not after Build with AI or an export. Lifetime plans, the Investor Package, credit purchases and subscriptions are excluded; a Lifetime report gets a rerun or replacement instead.
Does Preuve AI use my idea to train AI models?
The terms say your idea is processed by Google, Anthropic, OpenAI and xAI under enterprise API terms that prohibit training on your data, sometimes through Amazon Bedrock and OpenRouter. Market-data providers receive only broad market and category terms. You keep ownership of your ideas, and Preuve AI says it never shares them publicly or sells them.
How reliable is the Preuve AI score?
It is a model assessment of the idea and its market from public evidence, not a prediction of success or a measure of your ability to execute. The method behind the six factors is not published, and the terms warn that reports may contain errors or outdated information and that sources should be checked. We did not test it, so check the linked sources yourself.
Can I run Preuve AI from Claude or Cursor?
Yes. A remote MCP server at mcp.preuve.ai/mcp works with Claude, Claude Code, Cursor, Codex and ChatGPT, and an HTTP Agent API exists. A starter scan through MCP is free and draws on the starter allowance; a deep scan uses your paid quota, with no separate API fee according to the vendor.

Official pages read on 21 Oct 2026 with plain HTTP requests: pricing page, agent and developer reference (dated 19 Oct 2026), Terms of Service (21 Oct 2026), how-it-works, about page and the homepage description. We did not create an account, run a scan or open a report, and did not review the privacy policy, security, sources or facts pages. Official pages differ in places: the terms list the top 5 competitors in the free check while the pricing page says 2 previews; the pricing table shows no guarantee for Lifetime while the terms allow a rerun or replacement; the pricing page marks a 15-competitor map as limited for the free plan without saying what is shown. Counts of ideas scanned, review totals, testimonials and the vendor's comparisons with other tools were not used. Third-party prices and reviews were not used, and some still show superseded prices. The Google related questions for the product name were generic AI pricing queries.
