Readable vs Dubbah

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.

Dubbah dubs videos into 14 languages locally on your Mac without shipping files to the cloud. Drop an MP4 or MOV, pick target languages, and the app translates dialogue, clones the speaker's voice tone, and lets you edit every line before export.

Cloud dubbing services charge per minute and keep copies on remote servers. Dubbah runs on macOS 13+ for Apple Silicon and Intel, works offline after setup, and stays free with no subscriptions or per-minute metering according to the product site.

Creators, educators, and indie filmmakers use Dubbah when they need multilingual cuts for social clips, training videos, or client deliverables while keeping sensitive footage on the machine. There is no account signup; download the app and start dubbing immediately.
