What is the Wynter Message Grader?

The Wynter Message Grader is a free AI message testing tool from Wynter. Fifteen AI-simulated B2B personas read a web page you choose and answer the four questions of the Message Layers framework: whether they understand what you do, whether they think it is for them, whether they want it, and whether they can tell you apart from alternatives. The report names the weakest layer and gives specific edits to fix it.

Is the Message Grader really free?

Yes. There is no card, no subscription and no trial period. You enter an email address to receive the report, and that address is subscribed to Wynter's weekly B2B messaging newsletter, which you can leave at any time. That is the whole exchange.

Are the respondents real people?

No. The Message Grader uses AI-simulated personas, and every report says so. Each persona is sampled in code across role, industry, company size, seniority and buying style, then answers the questions independently. Wynter's paid research uses real people: over 80,000 verified B2B professionals who answer within 48 hours.

What is the Message Layers framework?

Message Layers is Wynter's framework for how B2B buyers read a page, in order. Clarity: can they say what you do? Relevance: can they tell quickly who it is for? Value: do they want it? Differentiation: can they say why they would pick you over a similar option? Each layer depends on the one before it, so the report fixes the earliest failing layer first.

How long does a test take?

Most tests finish in a few minutes. You paste a URL, describe your buyer in your own words, and watch the run. The report link is also emailed to you, so you can close the tab.

What is the Sameness Checker?

The Sameness Checker is Wynter's free competitor messaging comparison. It reads your page and up to four competitors' pages, breaks each into atomic claims, and computes a Sameness Index from 0 to 100: how much of what you say is also on their pages. It also lists what only you say, what everyone says, and how you compare to category leaders across more than 60 B2B categories.

How is this different from paid AI research tools?

Paid tools sell synthetic respondents on a monthly subscription. Wynter gives the AI version away because synthetic research is cheap to run, and makes its money on the human version. The Grader keeps the method honest in code: personas never see the hypothesis, scores come only from constrained verdicts, and every finding links to the simulated answers behind it.

Yes. A report is reachable by anyone who has its link, it is listed in the site's sitemap, and search engines and AI answer engines may index it. The claim-level detail behind your verification code stays private. Reports are deleted after 60 days, after which the link no longer works.

AI-simulated

Find out where your message loses buyers.
Free, in four minutes.

AI-simulated B2B personas read your page and answer the four questions from the Message Layers framework — the same framework behind Wynter’s human panels, built by the people who wrote it. You get the weakest layer, and the edits that fix it.

The four layers

Your message has four jobs. They only work in order.

They don’t care about your value until they get what it is. Miss an early layer and everything after it is wasted.

Clarity

Do they understand what you do?

The gate. If a buyer can’t name your category after reading the page, nothing further matters.

Relevance

Do they think it’s for them?

Buyers rule you out fast. This finds the ones who understood you but saw someone else’s product.

Value

Do they actually want it?

Comprehension isn’t desire. This separates “I get it” from “I want it”.

Differentiation

Can they tell you apart?

Usually the weakest of the four. Most pages never give a buyer a reason to pick them.

How it works

Paste a URL. Get a fix list.

Paste your URL

Homepage, landing page, or pricing page.

Describe your buyer

Role, industry, company size, region.

Specific edits per layer, not a score to admire.

Why free?

Others sell AI panels for $199 a month. We give ours away.

Synthetic research is cheap to run. Charging real-research prices for it is the business model of every “affordable Wynter alternative” — so we removed the price entirely. Run a test, keep the report, pay nothing.

We make the human version. The AI version is yours.

Same science the paid tools claim — with receipts

Trait-sampled personas — Big Five plus buying-style axes — not one prompt asked fifteen times.
Hypothesis-blind: respondents never see what you're hoping to find. Enforced by the software, not a promise.
Scores come only from constrained verdicts, so a page can't sweet-talk its own numbers.
Every finding chains to verbatim answers you can read yourself.

What this is, and isn’t

This is the free version of Wynter. On purpose.

The methodology is real, and it will find a vague headline or an undifferentiated value proposition reliably — for nothing.

What it cannot have is a real budget, a renewal coming up, or a boss asking about this quarter. For anything you’re actually betting on, test with humans who are in-market.

The real thing

Wynter runs the same four layers past 80,000+ verified B2B professionals in your exact target market, in under 48 hours.
