Honest market reads

Tell us what you're selling. We'll tell you if the market wants it.

Three questions, answered from live market data. Will it sell? If it's already out, what's holding it back? What do you fix first? Every answer graded by how much evidence stands behind it, never by what you want to hear.

Your first read is free. No card, just a free account.

What you get back

Three lenses, always moving.

Most tools tell you what you want to hear. MarkLens is built to disagree with comfortable assumptions. When the evidence is thin, it says so and scores lower, rather than guessing.

Three overlapping circles, labelled consumer, market and business, sit in a row with MarkLens on the point where they meet. Activating the diagram narrows them into lens elements that line up and focus an incoming signal onto one point, and MarkLens moves to that focus. Releasing it returns them to overlapping circles. The business lens is drawn with a broken edge because only the public part of a company's execution can be read from outside.ConsumerMarketBusinessmarklens.
At rest

Move over a lens, or tap one, and they line up to take a read.

Demand

Is anyone actually asking for this?

Live consumer signal across your category: what people are actually asking for, right now. Not a survey. Not last year's trend. Real conversations, grounded in sources you can trace.

Competition

Who else is already selling it?

Who is already there, at what price, and how crowded the shelf is. What is blocking a sale isn't always the thing you are selling. Sometimes the field is full and the price is in the wrong place.

Your position

How do you actually stack up?

What's publicly visible about your execution: distribution, listing presence, market visibility. And an honest flag when your own numbers are the only thing that can complete the picture.

The answer

The one thing to fix first.

The three come together into one answer: the real reason things aren't where you expected. The answer that stings is usually the right one. Grounded in sources, and honest about how sure it can be.

How a read works

One line in. A straight answer out.

Start with one line.

One line is enough: what you sell, what you're testing, and roughly where. "Oat milk, $5, DTC US" or "A boutique branding service, $4k/project" both work.

We check the live market.

We scan live consumer conversation and market data across your category, and run all three angles over it. Reasoning powered by Claude

You get a straight answer.

The constraint, the evidence, and the one move, in plain language. Act, don't agonise.

Divergence diagram. One question enters at the left and three muted paths curve away from it to three defaults a general AI model falls into: it encourages you because it is trained toward agreement, it answers from training rather than the live market, and it follows the framing of the question. A fourth path, drawn in green, runs to an answer grounded in what was actually found, searched first and then answered. A closing line notes MarkLens runs on the same models and changes the defaults rather than the intelligence.

You have ChatGPT open right now. Here is why that might not be enough.

We are built on Anthropic's models, so we will not pretend the general ones are weak. The gap is not intelligence. It is three defaults.

Usually the cause was legible in the signal beforehand. It just wasn't read.Jul 6, 2026The honest answer to “will it sell?”Confidence that outruns evidence isn't an answer: it's a guess wearing a suit.

What a MarkLens read doesFour scattered sources of market signal sit on the left, across a dashed baseline. Lines run rightward from each and converge, arriving at one verdict. The ring around that verdict is only partly filled, with the remainder left dashed, because the confidence it carries is limited to what the evidence supports.SCATTERED SIGNALONE GRADED VERDICT
