A proofreader for everyday short messages

Grammarly-AI Writing Assistant is a proofreader from Grammarly, Inc. that works in whatever app you are typing in, so it covers email, messaging and social posts without a separate editor. It is filed under Productivity, and its own summary describes it as an English proofreader for grammar, spelling, punctuation, vocabulary and fluency.

The listing names work emails written on the go, LinkedIn posts, text messages and tweets as the situations it is for. Anyone who writes short messages in English on a phone is the person it is pitched at.

Checking spelling, grammar and punctuation as you type

The checker reads each word you type and flags problems with spelling, grammar and punctuation. It also checks tone, so the same pass can catch a message that reads differently from how you meant it.

Because it runs across apps, you do not need to copy text into a separate editor to get the corrections.

Rewriting a message with generative AI

The AI rewrite tool produces new versions of a message and lets you choose between them. You select the style you want, such as more descriptive, more confident or more formal, and the listing mentions further styles beyond those.

The rewrite feature is described as generative AI, so the output is new wording generated from your draft rather than only corrections to the original.

Vocabulary and word choice

The listing says the app helps you enhance your vocabulary and spell-check individual words. This sits alongside the grammar and punctuation checks rather than replacing them.

Suggestions on word choice are aimed at making sentences read more clearly, which the listing presents as the purpose of the whole set of checks.

Using it for email, social posts and texts

The listing names emails, LinkedIn posts, text messages and tweets as typical uses. Since the checks run inside other apps, the same corrections and rewrites are available in each of them.

A person who writes a mix of work email and short social posts would use the grammar checks on both, and the rewrite tool when a draft needs a different tone or level of formality.
