Trancy Air
Trancy Air is a shortcut-driven translation and writing assistant for macOS and Windows. It helps people translate selected or on-screen text, draft and replace text in other languages, dictate content, and practice pronunciation across desktop applications.
Desktop translation across applications
Trancy Air is a shortcut-driven desktop translation and writing assistant for macOS and Windows. It is designed to work across applications: users can select text to translate it, replace text in an input field with a translated version, or dictate text instead of typing.
Beyond basic translation, Air provides word lookup, translation comparison, sentence alignment, grammar analysis, screenshot OCR, natural-sounding AI voices, and translation history. It also connects with the wider Trancy service for saved words, sentences, and pronunciation practice in the Trancy Learning Center. Core translation works without an account, while account-based AI and synchronization features require sign-in.
Core features
Translation comparison and alignment
Send a sentence to as many as five translation engines and compare the results side by side; long passages can be aligned sentence by sentence.
In-place writing assistance
Open a compose window to translate text, or replace text directly in an input field after writing in your own language. AI can flag grammar, spelling, and wording issues.
Voice input and rewriting
Hold a shortcut to dictate text into a field, optionally translate it, remove fillers, and rewrite the result into clearer paragraphs.
Screenshot translation
Drag across images, video frames, or interface text to extract and translate text that cannot be selected normally. Screenshot translation uses screen-recording permission when first enabled.
Language-learning workflow
Save words and sentences, search translation history, and sync saved material to the Trancy Learning Center. Pronunciation practice provides an overall score and per-word feedback.
Practical use cases
Reading foreign-language text
Select unfamiliar text in a desktop application to see a translation immediately, or inspect a single word's pronunciation, definitions, and usage examples without opening a separate dictionary.
Writing messages and documents
Draft a message in your native language and use in-place replacement to produce the target-language version. Grammar, spelling, and wording analysis can help refine the result before sending.
Voice-based drafting
Dictate when typing is inconvenient, then have the text translated, cleaned of fillers, or reorganized into clearer paragraphs for use in an input field.
Translating unselectable screen content
Extract text from an image, video frame, or interface element that does not support normal selection, then translate it through the screenshot workflow.
Building language-learning practice
Save unfamiliar words and sentences, revisit prior translations, and practice reading aloud with an overall pronunciation score and word-level feedback in the Learning Center.

- Combines translation with dictionary detail, grammar analysis, history, saved language material, and pronunciation feedback.
- Can use separate translation, voice, comparison, and OCR engines, including custom engines configured with a model and API key.
Cons
- The source does not specify minimum macOS or Windows versions, installation requirements, or a complete list of compatible applications.

FAQ
Which systems does Trancy Air support?
Trancy Air supports macOS and Windows, with the same features on both platforms. The source does not specify minimum operating-system versions.
Do I need an account to use Trancy Air?
No account is required for the built-in free engine. Selection translation, compare translation, and in-place replacement are available without signing in. An account is needed for AI engines, synchronized saves, and pronunciation scoring.
Why does Trancy Air request system permissions?
Trancy Air requests accessibility permission when it first needs to read selected text or write a translation back into an input field. Microphone access supports voice input, and screen-recording permission supports screenshot translation; these permissions can be skipped if the related features are not used.
What is included in the free version?
Core translation is free. Premium features include AI definitions, grammar checking, voice input, and pronunciation scoring. The pricing page also lists paid plans with additional AI and language-learning features, but it does not provide usable price figures in the source content.
How does Trancy Air relate to the Trancy browser extension?
Trancy Air uses the same account as Trancy's browser extension, sharing saves and settings. The extension is intended for immersive bilingual reading on web pages, while Air handles translation workflows outside the browser.
