DeepL vs Grammarly
DeepL scores 25 to Grammarly's 25 on public evidence for grammar, tone & editing, and they rank #1 and #2 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
DeepL
Neural machine translation praised for natural output in European languages, plus DeepL Write for editing.
+ Translations read more naturally than Google Translate for German, French, Spanish and other European languages, and it translates whole documents with formatting intact.
− Covers far fewer languages than Google Translate and the free tier caps document size.
Grammarly
A writing assistant that checks grammar, tone and clarity everywhere you type and rewrites or drafts text on request.
+ Works in nearly every text field on every platform, so corrections and tone suggestions follow you into Gmail, Slack and Word.
− Suggestions can flatten a distinctive voice and the premium nag prompts in the free tier are constant.
