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 content as you browse. Install it on Chrome, Edge, Safari, Firefox, or Opera, then get AI summaries for YouTube videos, Google results, Twitter posts, Gmail threads, PDFs, and any open webpage.

The extension runs on models including GPT-4o, Claude 3.5, and Gemini Pro. You can summarize full-length pages and videos, chat with page content, translate pages side by side, and use built-in writing help for emails and drafts. Glarity also offers Felo AI Chat with access to multiple models, a large context window, and image generation.

It suits readers who work across languages, researchers who need quick page and video digests, and anyone who wants ChatGPT-style tools inside the sites they already use. The core extension is free and ad-free; paid Glarity membership plans add higher token limits and advanced query allowances.
