Questions and answers

Does Do4U rewrite my text?

No. It only fixes spelling, grammar and punctuation. If the AI changes much more than that, Do4U shows a notice with the share of changed words, so you can check every change.

Which languages work?

German, English and Polish are tested. Other languages run as a beta: Do4U detects the language of your text and corrects it in that language, but please read the changes carefully.

How do I see what changed?

Removed text is struck through and added text is underlined, so it does not depend on colours. A list explains each change, and one click copies the corrected text.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?

Results are AI-generated. Please read them before you publish or send them.
