Phrase is an enterprise localization platform. Polylens is the quality gate for the files you already ship.
Phrase (formerly PhraseApp and Memsource) is an enterprise-grade localization suite: TMS, machine translation orchestration, analytics, and translator tooling. Powerful if localization is a department, heavy if it is a folder of JSON files.
Polylens reads that folder of JSON or YAML, scores every language, lists every mechanical failure, and breaks your build when quality slips. First score in under a minute, no SDK, no migration.
Phrase manages the translation process. Polylens verifies the result that actually ships. Many teams need only the second one, and it starts at $0.
