KeywordGraph SEO Browser Extension

What it does

The KeywordGraph extension reads whatever page you’re on and builds an interactive knowledge graph of its keywords. The graph shows the most important keyword combinations, the main topical clusters, and the gaps in the discourse — the topics that should be there but aren’t. It runs on Google results, so you can read a SERP as a topic map instead of ten blue links.

What you can analyze

• Google search results — the collective topic shape of the SERP
• YouTube search results and individual videos (auto-transcribed)
• Articles, newspaper pages, and any web page
• PDF files open in the browser
• Product reviews and ChatGPT conversations

What it surfaces

• Topical clusters. The groups of related terms that structure the page — your map of what a topic actually contains.
• Content gaps. Under-connected areas of the graph: the openings where new content has the highest informational gain.
• Research questions. AI-generated prompts that bridge the gaps, for ideation and briefs.
• Summaries and chat. A built-in model summarizes the page and answers questions against its content.

Supported browsers

• Chrome and Chromium browsers — via the Chrome Web Store
• Firefox — via the Firefox Add-ons store
• Safari (macOS and iOS) — in beta via TestFlight

How to install

1. Install from your browser’s official store.
2. Optional: sign in with your KeywordGraph account or add an API key to unlock saved graphs and extended usage.
3. Open a Google search, video, PDF, or article and click the extension button.
4. Read the topics and content gaps it surfaces on the page.

It works without an account for quick checks; signing in lets you save graphs and push any page into KeywordGraph for deeper analysis. Settings let you change the AI model, move or hide the button, and turn off auto-analysis.
