AI localization software: what they are and who makes them
developer-first string platforms, open source and self-hosted systems, broad localization management suites, language professional environments: Tolgee, Localazy, Lokalise through LILT.
Types of AI localization software
Developer-first string platforms
Tolgee, Localazy, Lokalise and Lingo.dev connect to code repositories, CLIs and CI, and treat translation as part of the build. They fit web and mobile teams that ship often and want new strings drafted by AI, with people reviewing only what a score flags.
Open source and self-hosted systems
Weblate is free to run on your own servers under GPLv3+, and Tolgee sells an on-premises licence. They suit projects with community translators or strict data rules, and the cost is that your own team runs, patches and backs up the instance.
Broad localization management suites
Crowdin, LingoHub and POEditor combine an editor, translation memory, glossaries and connectors for design tools, CMS platforms and stores. Pricing models vary from word counts to strings to flat plans with credits, so compare them against your own volume before choosing.
Language professional environments
translate5, memoQ, LILT and Gridly serve agencies and corporate language teams with licences for project managers and linguists, terminology tools and human routing. They fit document work more than app strings, and most of them require a sales conversation or a yearly licence before any use.
