The extension supports Gmail, Facebook, and even social media platforms like LinkedIn and Twitter. If you’re a Google Chrome user, you can get the Grammarly extension to check your words as you type. It’s also the best free grammar check software on this list, thanks to its comprehensive free plan.
I found its strongest features to be ease of use, integrations, and accurate results. It offers a robust set of features for individual users as well as for businesses and teams of all sizes. Grammarly is the overall best grammar checker software thanks to its accuracy, wide range of features at a reasonable price, and built-in integrations with popular tools and platforms.
