Clean little extension that actually respects your workflow.
Love that it's open source and uses my own API key.
Beats scrolling through giant PDFs looking for one fact.
UI is super basic but gets the job done.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Your question is answered using the content of the page you have open, so results stay grounded in the source you are reading rather than the open internet.
Instead of matching keywords, it locates the passages that actually relate to your query and uses them to build the answer.
The retrieved snippets are turned into a readable answer by an OpenAI GPT model, giving you a sentence or two rather than raw excerpts.
You connect your own OpenAI key, so you control usage and cost and the extension has no separate subscription.
The extension's code is public on GitHub, so you can inspect how page text is handled before installing it.
Sloth Search solves a narrow but constant problem: you have a long page open — a Wikipedia article, documentation, a report — and you want one specific fact out of it. Rather than scrolling and using the browser's text finder, you ask a question in plain language and the extension answers from the page content itself, showing which snippets the answer was built from.
It works through the extension's own pipeline: the page text is extracted, the parts relevant to your query are identified, and a short answer is composed by an OpenAI GPT model. This means answers stay anchored to the open page instead of pulling in unrelated knowledge from the wider web, which makes it useful for text-heavy sites where the answer is definitely somewhere on the page but not where you expect.
Sloth Search is free and open-source, published by an independent developer, and it requires you to supply your own OpenAI API key — the extension itself does not bundle model access. It is a small, single-purpose tool rather than a full AI browsing assistant, and it is best suited to people who already have an OpenAI key and want a faster way to interrogate long documents.
Pull a specific number, date, or definition out of a lengthy Wikipedia entry or report without scrolling through it end to end.
Ask what a page says about a function or configuration option and get a direct answer from the documentation text.
Turn a dense reading into quick comprehension checks by asking targeted questions about the page you have open.
Get to the relevant figures inside long reports faster by asking about them directly instead of skimming.
