Are you actually allowed to upload this text?
With confidential documents that is not a rhetorical question. Cortility translates directly on your machine. The text never leaves your PC — no upload, no website, no account.
Free: your language ↔ English

The moment of hesitation
There is a paragraph in front of you that you need in another language. You know the translation services, and you know they are good.
And still you hesitate — because that paragraph contains a client's name. Or contract terms. Or a diagnosis.
Usually convenience wins. Sometimes caution does, and you translate by hand. Neither is satisfying.
We are not claiming to be better
The large cloud translators are excellent. They run in data centres nobody fits under a desk.
Cortility runs on your PC. With very long, literary or stylistically demanding texts you will notice the difference.
With everything else — emails, paragraphs, notes, technical texts — you get a translation you can work with. Without anyone else ever seeing it.
The question is not which translator is best. It is which one is allowed to receive the text.
No tab, no website, no login
Straight from the dashboard: one hotkey, one tile.
The translation appears while you are still typing.
One click and the translation is in your clipboard.
Your language and English, free. Nineteen from Pro.
The free version translates between your system language and English — enough to judge whether the quality is good enough for your day-to-day work.
Pro adds 19 languages, free choice of model, and GPU acceleration when a dedicated graphics card is present.
Confidential stays confidential
No website, no account, no upload. The translation happens where the text already is: on your machine.
Cortility Pro costs €29.99 once.
Frequently asked questions
Does translation really run fully offline?
Yes. The model is downloaded once, after that no connection is needed.
How does the quality compare to cloud services?
Good enough for everyday text, weaker with literary or very long texts. The free version exists precisely so you can judge that yourself.
Which languages are supported?
Your system language and English for free. From Pro, 19 languages with free choice of model.
Do I need a graphics card?
No. A dedicated graphics card makes translation faster.
Is the text cached anywhere?
Not outside your machine. There is no server access, not in the background either.
