Readable vs Glarity

Readable translates PDF files into Japanese while keeping the original layout intact, including tables, figures, and images. Built by NextLab Inc., it targets researchers reading academic papers and business teams working through manuals, reports, and contracts without rebuilding documents by hand.

The reader shows original and translated text side by side so you can scan a translation and jump back to the source line when something needs a closer look. Premium users can register custom dictionaries so product names, abbreviations, and field-specific terms translate the same way every time.

Readable runs in the browser and through a Chrome extension for quick file translation. Pro Standard focuses on English-to-Japanese PDFs, while Pro Premium adds 200+ source languages, larger file limits, and optional ChatGPT-based translation engines.

Glarity is a free browser extension from Felo Inc. that summarizes and translates pages as you browse. Install it on Chrome, Edge, Safari, Firefox, or Opera to get summaries for YouTube videos, Google results, Twitter posts, Gmail threads, PDFs, and any open webpage. It runs on models including GPT-4o, Claude 3.5, and Gemini Pro, and the core extension is ad-free.

Most standalone chat tools make you copy URLs into a separate window. Glarity embeds summaries, side-by-side translation, and page Q&A directly in the sites you already use, including an open-source extension repo on GitHub. Compared with default ChatGPT limits, Glarity membership advertises unlimited-duration YouTube summaries and PDF handling for roughly 300 pages versus four-page caps on the free ChatGPT side.

It suits readers working across languages, researchers who want quick digests of pages and videos, and anyone who prefers AI helpers inside Google, YouTube, and Gmail rather than switching tabs. Paid Glarity Standard, Pro, and Plus plans add higher monthly token limits and advanced query allowances when the free tier is not enough.
