DeepL Write

I'm currently testing both Grammarly and Microsoft Editor — both integrated on my web browsers (via extensions, available for all browsers) as well as Microsoft Word. Grammarly has a slight edge over Microsoft Editor when correcting/suggesting grammar in English; Microsoft Editor, on the other hand, supports many, many more languages besides Grammarly — and it's totally free (at least for now).

DeepL Write is — at the time of writing this review — still in its infancy.

While DeepL's translation abilities are legendary, which makes DeepL Write a rather interesting choice (it certainly outperforms Grammarly & Microsoft Editor), for now, it's only available either on a plain old web page, or via their extensive API. Both are free to use for a certain number of times per month; their tapped knowledge is not exactly cheap, but worth considering if you're a professional writer. However, you'll get far less than with Grammarly — for the time being.

Unless, of course, you're a developer yourself, wishing to compete with Microsoft and Grammarly, and having the necessary skills to write browser extensions and word processor plugins — in which case connecting to DeepL as the back-end tool would give you a complete, professional solution able to compete with Grammarly & Microsoft.

But for the common user? Well, we'll have to wait until DeepL launches — at the very least — an extension for Chromium-based browsers (and possibly adds a few more languages, too); in that case, they could come closer to Grammarly & Microsoft in providing a 'complete solution', so to speak, and would be more easily compared (or at least comparable).
