Its recorded strengths include Translation, Writing, Localization, Document translation, and the current platform coverage is web, ios, android, desktop, api. Before making it a core tool, test it with real source material, representative edge cases, and the output format your team expects to review.

For teams, the review should also cover privacy terms, account administration, export options, repeatability, and whether the workflow still works when a quota, model, or pricing plan changes.
