Beyond regular websites, it can search the text content of your Google Docs documents as well.
Get a response in seconds, even from pages with tens of thousands of words, by letting the model read the text for you.
Available free from the Chrome Web Store, with the developer stating that no user data is collected or misused.
Semantic Search exists to solve a small but constant annoyance: you land on a dense, text-heavy page and just need one fact from it. Rather than scrolling and skimming, you ask. The extension reads the current page's text, combines it with your question, and sends both to ChatGPT, which returns an answer grounded in that page's content.
The extension has evolved through several backend changes. It began with a custom model inference pipeline, moved briefly to banana.dev, and from version 1.3.0 onward has used ChatGPT directly. Later updates added Google Docs support and routed requests through a Cloudflare Worker proxy, and version 1.4.0 upgraded the underlying model to GPT-4o-mini for faster, more accurate answers. Because it relies on ChatGPT's servers, context length is capped around 11,000 words per query.
Semantic Search is offered free by independent developer Luke Sutor and reflects a focused, single-purpose design: parse a page, answer a question, get out of the way. It suits readers, researchers, and students who frequently need to pull answers out of long documents without leaving the tab.
A student on a long Wikipedia or article page asks a question and gets a direct answer instead of skimming for the key sentence.
A developer opens technical documentation and queries it for a specific configuration detail without leaving the page.
A reader working inside Google Docs uses the extension to pull specific answers out of their own long documents.
Anyone who frequently reads dense material gets the relevant sentence fast, improving focus and cutting wasted scrolling.
