Chrome extensionSEO, GEO and AEO
Lumi GEO shows what AI crawlers really read on a page, what they miss, and gives you the code to fix it.
Demo · 26 seconds
One full analysis of a fictional demo site: the robot view right on the page, the score, then the code to copy.
The problem
They only read the HTML sent by the server. Whatever a site adds afterwards with JavaScript does not exist for them: they can’t understand it, so they can’t cite it.
That’s where I come in: I read the page like they do, then I show you what they miss.

On the fictional demo site shown on this page, 70% of the text only appears after JavaScript runs.
How it works
No account, no setup: Lumi GEO works on the page you are looking at.
I tell you each step as I go: no black box.
On any page, in Chrome. The side panel opens for this tab only, then you start the analysis.
Like an AI crawler: the raw HTML, robots.txt and the structured data. About three seconds.

Analysis finished: 75/100
A score out of 100, the priorities with the points they are worth, and the code to copy.

Robot view
Lumi GEO downloads the raw HTML of the page and compares it with the page on your screen.

The score
Each problem fits on one line, with what fixing it is worth. One click opens it: what it means, how to fix it, and the code to copy.
Very good foundation! Most important: 70% of the text is invisible to AIs.

AI crawlers
For each AI crawler (search, on-demand browsing, training), Lumi GEO tells you whether it can read the site and the page, with the exact robots.txt line that decides.
Blocking training crawlers is a legitimate editorial choice: it costs no points.
A blocked search crawler can’t cite the site. A blocked training crawler? That’s the site’s call.
robots.txt
User-agent: *Allow: / User-agent: GPTBotDisallow: / User-agent: PerplexityBotDisallow: /Line 8: “Disallow: /”. It cannot cite the site.
An editorial choice: no points lost.
Lumi reads the pagePro
With the AI built into Chrome (Gemini Nano), which runs on your computer:
An answer only counts if the quoted sentence really exists on the page: the AI cannot invent anything.
InfoRequires a compatible computer (requirements set by Chrome). Otherwise, everything else works normally.
Lumi reads the pagePro
« Du mardi au dimanche, de 6 h 30 à 19 h 30. »The page does not answer it: an idea for the FAQ.
No quote, no answer. That’s my golden rule.
The code
I never fill a blank with a guess: you’ll see “TO COMPLETE” instead.

Yes, up to 5 full analyses a day: the 4 pillars, the robot view, the AI crawlers and the code to fix it. Re-analysing a page already analysed today is free, and past 5 pages, new pages still show their score and their 4 pillars. Lumi GEO Pro (€9.99 per month, no commitment) adds unlimited analyses, Lumi reading the page with Chrome’s AI, score tracking for each page and the PDF report. Your first PDF audit is on the house.
Two reports from the same analysis. The client audit carries your brand (name, logo, client): the current score and the score once everything is fixed, a summary, an action plan in steps with the effort and the points of each fix, the detail of every fix with its code, and annexes (AI crawlers, Google preview, structured data, speed, trust signals, glossary). The fix plan is for you: every fix in order, with the code and a ready-made prompt for ChatGPT, Claude, Cursor or Copilot. Everything is made in your browser and saved as a PDF by Chrome.
GEO (generative engine optimization) helps generative AIs like ChatGPT, Perplexity, Claude or Gemini understand, trust and cite a page. AEO (answer engine optimization) is about giving clear, direct answers to the questions people ask. Lumi GEO checks both, along with classic SEO and what AI crawlers see without JavaScript.
No. The score is an indicator of Lumi GEO, not a Google or AI metric. It shows what helps AIs read and understand a page, and what to fix first; nobody can guarantee a citation.
Yes: any web page open in Chrome, yours or not. Chrome does not let extensions read its own pages (chrome://…) or the Chrome Web Store. Lumi GEO only reads the page you click on, when you click.
No browsing data is collected: the analysis runs entirely in your browser, with no telemetry and no ads. Pro subscribers: only the license key is checked with Lemon Squeezy, the payment provider. No analysis result is ever sent.
It uses the AI built into Chrome (Gemini Nano), with requirements set by Chrome: Chrome 138 or newer on Windows, macOS or Linux, 22 GB of free space, and a graphics card with more than 4 GB of memory or 16 GB of RAM. The first time, Chrome downloads its model. On other computers, everything else in Lumi GEO works normally.
Not necessarily. llms.txt is a community proposal, not an official standard, and it does not guarantee being cited by AIs. Lumi GEO checks it as a bonus, without counting it in the score.
You pay securely with Lemon Squeezy, the payment provider. Your license key arrives by email: paste it in Lumi GEO with the Pro button. The subscription costs €9.99 per month, with no commitment, or €89 per year (3 months free).
Chrome 116 or newer on a computer, and Chromium browsers compatible with Chrome’s side panel. The interface is in English and French, following Chrome’s language.
