The following localization management platforms all offer powerful translation tools but excel in different areas. Here’s how they match up:

1. Crowdin AI Localization – Best Overall

Crowdin is our current top pick for best AI localization software. The online solution streamlines the process of handling multilingual content, including web, mobile, and desktop applications. As well as games, websites, marketing materials, and documentation.

Its AI suite excels at deep context harvesting (prompt, file, segment-level), quickly understanding the intended meaning, tone, and culture for high quality translations.

The AI learns from your corrections, and you can even fine-tune models with your own Translation Memory, which gives you a strong ownership over your AI translations and data privacy.

Crowdin’s powerful and yet user-friendly editor has built-in AI assistance and features like AI Proofreading Agents, automated QA checks and Agentic AI (currently in Beta) for consistent quality.

2. Locize – Best for JavaScript Projects

Locize is a cloud-based localization management platform designed to help businesses and developers efficiently manage translations. It suits any software project, such as mobile apps, websites, video games, and more.

It is designed to work seamlessly with the i18next JavaScript internationalization framework, making it our top pick for JavaScript-based projects.

All it takes is one line of code and Locize’s user-friendly web interface is ready to efficiently translate content.

By creating and managing custom glossaries, you also ensure that specific terms and phrases are translated consistently.

The review workflow feature lets you manage the quality and accuracy of translations before they are published, and you can add versions to projects to stay on top of changes.

Locize makes it easy for users to collaborate in real-time, and its tenant feature supports the management of translations across different projects or brands.

You can try Locize for 14 days and the scalable pricing model starts from just $5/mo.
