Hundreds of questions, every week

Looking for the questions that decide.

Every dot is a question a buyer asks AI. We run them all, across eleven engines, and show the ones that lead to you and the ones that lead to a competitor. Hover over it.

How we choose the questions
Full screen ↗
02 · Periscopy

It is not a dashboard. It is an agent working for your brand.

Every week, without anyone asking: it measures, reads, explains, decides what matters and prepares the pieces. Ten systems cross-read into one reading.

01 · Measure

Eleven engines, two modes, every week.

Citation, share of voice, share of recommendation and position, with full history. Model memory and live search, read separately.

PeriscopyDemo · fictitious brand and data
Fact checking

What AI states, against the facts.

Prices, addresses and terms checked against the record. Every mismatch becomes a fix before a buyer reads it.

Personas and funnel

Measured the way the buyer asks.

Every question carries the framing of a persona and a funnel stage: the decision-maker, the technical lead, the local buyer.

Cited sources

The sites AI reads, question by question.

Which domains each engine cites when it searches, question by question, and which ones repeat across engines. That is where your content needs to be.

Choice, not just mention

Appearing is not being recommended.

We separate a brand named in a list from the brand the answer picks. That is share of recommendation, next to share of voice.

Commerce observatory

Shopping carousels, seen from the inside.

Title, merchant, price, rating, position and sponsored badge, item by item, as the buyer sees them.

Alerts

When the brand drops out, you know the same week.

A fall in citation, share of voice or position against the week before, and the week it stopped being named, engine by engine.

The architecture · Signals, brain, products, action

One system. Not a list of loose services.

Everything we measure feeds a single brain, the SINAL method, and everything it decides becomes a product you use and an action we carry out. Top to bottom, no black box.

05 · What to demand

Seven questions for any GEO provider.

Ask them of us too. Every answer of ours has public proof.

Do they measure with their own technology, every week?
●Periscopy, 11 engines and surfaces.
Third-party tools, or one-off measurement.
Is the method published?
●SINAL, 8 dimensions, in the playbook.
Internal method, rarely published.
Do they produce primary research?
●Our own studies and datasets, public.
They quote studies from other markets.
Do they monitor forums and community?
●Reddit, Hacker News, forums and social.
Out of scope in most proposals.
Do they show the AI crawlers on your site?
●GPTBot, ClaudeBot, PerplexityBot.
As a rule, not even measured.
Does every action have a before and after?
●Action date and citation before vs after.
Reports of what was done, not of what changed.
And if you leave?
●You keep the work, the documentation and the history.
It varies. Ask before.

“Common practice” describes the market pattern, not any specific vendor. There are exceptions. And if you find one that fills the whole column, compare us line by line.

of mentions become a choice when you ask for the best Portuguese brands. Being named is not being chosen.

16 questions about the best company in each sector, 10 AI assistants, 616 answers read one by one. In supermarkets, 96% of mentions are choices. In banking, rewording the question reorders the ranking. Open data, published method.

See also the Portuguese B2B SaaS study (45 companies: 56% recommended by no assistant), the Google against AI barometer (251 B2B companies: 41% invisible in AI despite strength on Google) and the measured cases.

Our own software

We do not promise visibility. We measure it.

It is no longer just the text AI writes. It is the products it shows with prices and stars, the Amazon assistant that picks for you, the press, reviews and forums all of it comes from. We measure that whole layer with our own software, every week, and we do the work that changes the answer.

We run your buyers' questions where they actually ask them: assistants, the products AI shows with prices, maps and reviews. You don't get a report. You get the fixes shipped, measured week over week, and the models that anticipate the next answer.
