Private Translation, Spell & Grammar Checker Tools

Private alternatives to Google Translate, Grammarly, Microsoft Translator, vetted against our public criteria.

The text you paste into a translator is often the most sensitive thing you handle: contracts, medical notes, private messages, and the big free services log it to train their models. These translation and grammar tools get you the meaning without keeping your words. Some even run entirely offline.

Why translation is a privacy problem

People paste genuinely private text into translators and grammar checkers without a second thought, and the mainstream free ones retain it. That text can include names, health details, legal language, and trade secrets. A privacy-respecting tool either does not log what you submit, or processes it on your own device so nothing is sent at all.

What to look for

A clear no-logging or no-retention policy, an offline mode so sensitive text never leaves your device, open-source engines where possible, and the option to self-host for full control. Offline translation is the gold standard: there is nothing to log because nothing was ever sent.

Translation and grammar both

The same logic covers grammar and spell checkers, which see every word of your drafts. Prefer one that runs locally or promises not to retain your text, especially for anything you write that you would not want sitting on someone else’s server.

Frequently asked

Is the quality as good?
For most languages the gap is small, and for some pairs the alternatives are excellent. Since the text you translate is often sensitive, slightly different phrasing is a fair trade for not handing it over.
Can it work offline?
Several options run entirely on your device with downloadable language packs, which is the most private setup possible: the text never leaves your machine. It is also handy when you are travelling without a connection.
Do they keep what I translate?
The privacy-focused tools here either do not log your text or do not retain it, and the self-hosted ones never send it anywhere at all. That is the whole reason to switch, since translated text often contains exactly what you would least want stored.
