TranslateAir is a macOS application that brings AI-powered translation and OCR directly into your workflow. It offers system-wide integration (menu bar and a floating bar) to translate selected text from any app, while also extracting text from images, videos, PDFs, designs, and even source code via OCR. After translation, you can use the One-Click Polish feature to rewrite the text to be friendlier, more professional, shorter, or more detailed, all within the same workflow. The app supports multiple translation engines (with the ability to switch between them) to balance speed and accuracy. Keyboard shortcuts are customizable for translations, OCR, and the floating bar, and the product claims compatibility with 1000+ Mac apps. Language coverage exceeds 100 languages for both translation and OCR. An offline mode is not available today, but offline support is listed on the roadmap. The pricing model includes a free plan (trial) providing a pool of translations and a yearly subscription plan that totals $29.99/year (expressed as $2.50/month billed annually), with the option to manage subscriptions inside the app. Privacy and data handling emphasize transient processing of translation content and third-party APIs (OpenAI, Google Translate, DeepL, Gemini) with encryption in transit.
