The Glippy Extension for Chrome
The Glippy Extension grades any webpage for AI search and agent readiness in a single click. Run 240+ checks across 16 GEO categories, work in 31 languages, and layer on optional LLM-powered content analysis — all without leaving your browser.
What the Glippy Extension does
Install the Glippy Extension, open any page, and click the toolbar icon. In seconds you get a GEO readiness score from 0 to 100 with a letter grade, a per-category breakdown, and prioritized tips for your weakest areas. The score also lands right on the extension icon as a color-coded badge so you can audit while you browse.
- One-click scoring — instant GEO score and grade for the active tab
- Per-category detail — expand any of the 16 categories to see exactly which checks passed, warned, or failed
- Trend tracking — stores up to 50 scans per URL with a sparkline so you can see if your changes are working
- Competitor comparison — scan a rival URL side-by-side across all 16 categories
- Multi-page & bulk-tab scans — audit up to 10 URLs at once, or every open tab
- Exports (Pro) — HTML, PDF, Markdown, CSV, plain text, and direct upload to Google Drive
Privacy first: Glippy analyzes pages entirely in your browser. No page content is sent to Glippy servers — the only network calls are license verification and the optional LLM analysis you configure yourself.
All checks the Glippy Extension runs
Glippy evaluates 240+ signals grouped into 16 categories. Categories 1–10 score technical readiness; categories 11–16 score the content itself. Each category is weighted by its impact on how AI agents and generative search engines discover, understand, and cite your page.

0.5× weightLanguages the Glippy Extension supports
The Glippy Extension interface is fully localized into 31 languages and follows your browser language automatically. Glippy analyzes pages in any language — this list covers the languages the extension UI itself is translated into.
Using the LLM option
By default, Glippy scores the 16 categories with fast in-browser heuristics. The content categories (11–16) — positioning, freshness, information density, verifiability, comprehensiveness, and multimodal — are judgement calls that benefit from a real language model. That's what the LLM option is for.
The LLM option is a Pro, bring-your-own-key (BYOK) feature. When you turn it on and add your own API key, Glippy uses your chosen model to evaluate the content categories more deeply and folds them into your overall GEO score instead of keeping them as a separate Content score.
How to enable it
- Activate Glippy Pro in the extension (the LLM settings are Pro-only).
- Open Settings → LLM Analysis in the extension popup.
- Pick a provider and paste your own API key, then choose a model (a fast default is preselected).
- Click Test to validate the key, then Save. A status indicator confirms LLM analysis is active.
- Re-scan any page — the content categories are now LLM-assessed and counted toward your GEO score.
Supported LLM providers
You bring your own key for any one of six providers, so you stay in control of cost and model choice:
Anthropic Claude
Haiku 4.5, Sonnet 4.6, Opus 4.7 and more
OpenAI
GPT-4o mini, GPT-4o, GPT-5 mini, GPT-5
Google Gemini
Gemini 2.5 Flash & Pro, 3.x previews
Groq
Llama 3.3 70B, Llama 4 Maverick
DeepSeek
DeepSeek V3, DeepSeek R1
Mistral AI
Mistral Small, Mistral Large
Your API key is stored locally and used only to call the provider you select. With the LLM option off, Glippy still scores all 16 categories using its built-in heuristics — the key just unlocks deeper, model-graded content analysis.
