Glotera AI

Glotera AI approaches translation as an input-layer problem rather than a document-processing one. Its core inline mode works like this: you write in whatever language comes naturally, append a trigger such as @en or #ja, and the tool immediately swaps your original text for the translated version in the same field. Double-tapping the space bar triggers the same action, so the translation happens without leaving Gmail, X, Discord, WeChat, WhatsApp, TikTok or any other input box on the system.

Beyond inline typing, Glotera offers a selection translation mode that works system-wide: highlight text in a desktop app or on a web page and get a floating translation window. A screenshot translation feature, mapped to Shift+Option+S by default, uses AI text recognition to translate text inside images, diagrams and photos, and supports follow-up questions about what it read. A newer Translation Copilot mode targets WhatsApp specifically, reading incoming messages and translating them into your language while translating your replies back into the sender's language, without any manual trigger. The company advertises support for more than 100 languages and claims over 95% accuracy, with context-aware phrasing.

The app is built for macOS only at present, with other platforms described as in development. It is deliberately small — under 5MB — and runs on cloud AI, so an internet connection is required. Glotera states that translation data is encrypted in transit and that it does not store personal information or translation content, keeping your material on your device. The site also publishes comparison pages against Google Translate, DeepL and Grammarly for people deciding between tools.
