The reads your idea can takeDemand, the ground under a local service, the marketplace when your idea sells through listings, the name — read together in EN, FR or ES. An axis that cannot apply to you is named, not sold.
No single point of failureCommunity forums, marketplaces, registries, search data — when one API dies, your report doesn’t. A failed source is disclosed: unknown, never zero.

Start here

Start from what you are making

Each path asks for your idea in its own words, and measures what can honestly be measured for it — nothing more, and it says so.

For a SaaS, a tool, an appIs the pain real, or just plausible?

The communities where your users already complain, quoted and verified, with measured search demand behind it.

Measured interest in your topic and where it lives — with what we cannot see named, not hidden.

The spine

Every report answers six questions

The same spine on every idea — each answer built only from what your run measured, each citation opening to its source.

  1. Is there real demand?

    Signals read, pain ratio, measured search volume — with the confidence ceiling explained rather than assumed.

  2. Is anyone acting — or just talking?

    Who says they would pay, who is actively looking, who is coping badly. The words people used, not a forecast.

  3. Who already serves them?

    The alternatives your own evidence names — with the quotes that name them.

  4. Where should you attack?

    Countries ranked by what we could measure there, and the angles that cleared a statistical bar — the ones that did not are kept visible too.

  5. Can you own the name?

    Names checked against the live domain registry. Available means checked, never guessed.

  6. What would kill it?

    Every risk labelled: checkable this week, or the model reasoning. You always know which one you are reading.

How it works

One seed. Four instruments. Every reading cited.

Type your idea once. DemandLens turns it into a measurement run across the places where demand actually leaves traces.

Demand, from real communities

We sweep real communities for your problem space and count only the signals that are actually about your idea — a blind source says so instead of faking a score. Every thread is linked, so you can read it yourself.

Listings, from the marketplace

Competition, price bands and buyer complaints come from actual marketplace listings — never from a projected “market size”.

Domains, verified live

A name is a proposal; availability is a fact. We only call a domain available after a live registry check.

The report

A report that answers your six questions.

  • It opens with the verdict.Score, confidence, the one risk that could kill it, the strongest angle to attack — on the first screen, then every number traces to a thread you can read.
  • Ranked by what people did.The commitment ladder separates talk from action — complaints, workarounds, money already spent — and every register is backed by a verified quote.
  • The case against, included.“What would kill it” and “what to test first” are standing sections — the report argues with you, not for you.

Our refusals

The restraint is the product.

No invented market sizes

If we didn't measure it, it isn't in your report. No “$4.2B TAM by 2030”.

No AI cheerleading

Every report states the case against your idea — “what would kill it” — plainly.

No silent failures

A failed source is disclosed at the top of your report. Missing data is unknown, never zero.

Pricing

Free scan. Full report, $24. That's it.

Transactional, per idea. Reports written in English, French or Spanish — country rankings built from what our sources actually measure, never an invented TAM. No subscription, no account, no upsell emails.

Watch what changed on an idea over time — a diff, not the same report again.

Kept for this alone, and only once you confirm — what we hold is on the privacy page.

Three failures entitle you to a refund — a blind scan, a duplicate charge, a non-delivery. Decided by the engine, not a support queue.

Questions

The honest answers.

How is this different from asking ChatGPT?

A chatbot answers from memory and wants to please you. DemandLens consults sources live during your scan, counts only the signals that are actually about your idea, and shows the verified quote when it checked one — including the case against it.

What does a low score mean?

A measurement, not an insult. The engine returns low scores by design, and the report names what would change the verdict and what to test first — a report that argues with you is worth more than one that agrees.

Why is there no market-size number?

Because nobody can measure YOUR idea’s demand from someone else’s TAM report. We never print a market size — invented or cited. We show what people actually said and did about this exact problem.

Which languages and countries?

Reports are written in English, French or Spanish. Country rankings come from what our sources can actually measure in each country — coverage is stated, never assumed.

What about refunds?

Three failures entitle you to a refund, decided by the engine: a blind scan, a duplicate charge, a non-delivery. Otherwise the $24 report is final — that’s exactly why the free scan and the public sample exist: check the goods before paying.
