Scored by a Toolio reviewer after real useOur verdict
Glarity is an open-source extension that summarizes YouTube videos, Google search results, webpages and PDFs using ChatGPT, with summaries generated across more than a dozen languages. Translation runs alongside that, with a choice of four engines and side-by-side mirror translation for reading two languages at once. It also handles email drafting help and lets you chat with a PDF or webpage's content directly, all built on ChatGPT rather than a mix of independent models.
