You upload PDFs, ask whatever you need to know — a specific figure, a definition, the gist of a chapter — and the assistant responds using only the contents of your documents. The distinguishing feature is citation: each answer is backed by a clickable reference to the page it came from, with the relevant passage highlighted, so you can verify claims instead of trusting the model. Search works across multiple uploaded documents, which is what makes it practical for literature reviews, contract comparisons and multi-file research. Beyond question answering, the site positions the tool for generating study material: summaries, study guides and presentation outlines built from the source PDF. Translations are supported across more than 90 languages, which helps when the source document is not in your working language. Organisation features include tagging documents and then chatting with groups defined by those tags, keeping separate projects from bleeding into each other. The site states it is trusted by over 500,000 researchers and professionals and offers a free entry point, with 'Try for Free' as the primary call to action on the homepage. The product is operated by Pearl Labs. Because a free tier is advertised but published price tiers are not shown on the homepage, check the signup or pricing flow for the exact limits on file size, document count and advanced features before relying on it for large workloads. **Pricing & Plans:** The site advertises a free way to start via 'Try for Free'.
