TransOne - AI Translator

About this app

<p>TransOne brings AI translation to your menu bar. Instead of relying on a single ordinary engine, it lets you translate with today's most capable AI models, for results that are natural, context-aware, and true to meaning, not just words.</p>
<p>Powered by AI you trust.<br />
Translate with today's leading large language models, alongside classic engines such as DeepL, Google, and Microsoft. Enable as many as you like, compare results side by side, and set the best one as your main translation with a click. Care about privacy? Apple's built-in offline translation (macOS 15+) runs entirely on your Mac, no internet required. On Macs with Apple Intelligence (macOS 26+), you can pick it as your on-device engine instead. Prefer local AI? Connect models running in Ollama or LM Studio.</p>
<p>Translate the way you work:<br />
• Type or paste in the quick translation window<br />
• Select text in any app and translate it with a shortcut, or replace it in place with the translation<br />
• Press ⌘C twice and the copied text is translated instantly<br />
• Capture a screen region to translate or copy the text inside it<br />
• Overlay translations directly onto an image, right where they belong</p>
<p>Smarter than a dictionary.<br />
For single words, AI and the built-in dictionary add phonetics, parts of speech, and real example sentences. For names and terms, TransOne shows a short encyclopedia summary. A natural voice reads any result aloud, and a one-click Polish refines your own writing without changing its language. Words you look up can be saved and synced to your Eudic or MaiMemo wordbook.</p>
<p>Built for privacy.<br />
TransOne runs fully sandboxed and collects no analytics. Your text is sent only to the AI service you configure, and your API keys are stored safely in the Keychain, never in plain text.</p>
<p>Make it yours.<br />
Set your preferred languages, choose where the window appears, pick a color theme, and assign your own shortcuts. Every translation is saved to a searchable history, and you can star the ones you love.</p>
<p>Try it free for 7 days. Unlock the app for good with a single one-time purchase, no subscription.</p>
