OOONA

Web-based subtitling toolkit for localization professionals

Our take

OOONA offers a browser-based suite of modular subtitling tools — Create, Translate, Convert, Review, plus Pro versions — that you license individually or as bundles. It is one of the few cloud platforms genuinely aimed at professional localisation rather than social creators. Freelancers can pick what they need without committing to a full suite.

In depth

OOONA is a web-based subtitling toolkit designed for professional localisation rather than creator workflows. The suite covers creation of subtitles from scratch, translation between language pairs, editing of existing files, conversion between formats, and review for quality control.

Each tool is licensed individually with a small monthly fee — Translate starts at $15/mo or $12/mo annual, with Create, Convert, and Review at similar entry points. Pro versions add shot change indicators, waveform graphing, and professional QC features.

Basic, Pro, and Full bundle packages collapse the individual prices for vendors who use the whole stack. That modular structure suits freelance subtitlers and small localisation vendors who do not want to commit to an enterprise suite but need real professional tools.

Format support is tuned for the audience — EBU-STL, SubRip, WebVTT, TTML, SCC, and the long tail of formats consumer tools omit. Reading-speed indicators, character-per-line enforcement, position controls, and quality validation all match what a professional localisation vendor expects.

The interface assumes professional knowledge — casual creators encountering it will find the terminology confusing and the visual styling functional rather than friendly. There is no animation, no template library, no aggressive word-pop aesthetic. For a freelance subtitler building a localisation career, OOONA is one of the strongest cloud options.
