- (2025-01-05) Paul McHardy (Head of Enterprise SEO): Kinda bloated unfortunately. Almost 40 MB of browser task memory.
- (2024-07-01) Jennifer Bessert: I have tried Grammerly and Outwrite. Both are helpful, but in operation and learning oppurtuities I found Outwrite to be a far better tool. It not only flags my errors but gives me suggestions in real time on how to fix the error and alternative ways to achieve the point I am trying to make. This has assisted me greatly in learning to write better.
- (2024-06-11) Melinda Bowman: I love outwrite! If you are having a hard time figuring out how to use it/access everything, play around with ti. That's what I did and now I love it. I can't imagine why anyone would say it doesn't work. Plus, it's a lot less expensive then some of the other spell checker type apps.
- (2024-05-17) Amelia: I tried it out on a few sentences and it didn't even fix my spelling or grammar. It did underline some things and say "This suggestion is only available to pro users" so it managed to be useless and annoying.
- (2023-08-11) Louis Barnett: Been using Outwrite now for 6 months, I've got to say i'm not very impressed. Many of the suggestions it offers don't make any sense. I left Grammarly which I had used for years and I've got to say i'll be returning to Grammarly asap. The UX / UI are great but functionality doesn't feel like it's improved the whole time I've been using it.

- (2023-06-03) Samuele gg: Ottimo per usare la formattazione dell'editor, non molto precisa, invece, la correzione dei testi, nel complesso il risultato si è dimostrato inaffidabile, non ha riconosciuto alcune parole. L'estensione è inutile, è solo un collegamento alla pagina intera che viene aperta in un'altra scheda. Great to use the formatting of the editor, not very precise, however, the correction of texts, overall the result proved to be unreliable, it did not recognize some words. The extension is useless, it's just a link to the whole page which is opened in another tab.
- (2023-06-02) Jessica S. (darkocean): Thank you for letting people try out your extension without sign up! The free version is just a spellchecker, that doesn't show me how useful this tool is when it comes to correcting *grammar* issues. (I might be wrong here!) Well, from what it flagged for me, anyway. It just occurred to me there might not be any grammar issues to correct in that chapter.... xD :P Give free uses like 1-5% grammar corrections (even if it's only for 30 days) to let us see how smart this thing is! For example the Grammarly app/program has become downright moronic with its corrections so, we need reassurance that your's isn't just another clone. Thanks for listening to the feedback, it's appreciated. <3

- (2023-04-24) Lorenza Holloway: I am liking this app very much! I am currently using it to check my Spanish grammar in my essays for my Masters program. One feedback I would give, is that I wish the same options to improve, shorten or expand the sentences was offered in the other languages (Spanish).

- (2023-02-26) Anonymous Z: A l'époque actuel ou la langue Française ce meurt de en plus en plus, notamment à cause de l'éducation National laxiste, de parents qui n'éduquent que très peu leurs enfants ,du Rap qui ne sait pas conjuguer 2 mots sans faire de fautes et ou les Jeunes ne connaissent même pas le Bescherelle si ce n'est que pour "caller" leurs lit … Ils ne lisent plus de livres ;seul compte "leurs" Tik-Tok; c'est pour dire le niveau .. ça fait plaisir et redonne de l'espoir au jeunes qui veulent s'instruire un minimum car grâce à ce genre d'extension, petit à petit ils parviendront à écrire correctement et a enrichir leurs vocabulaire . Il reste de l'espoir grâce à de telles initiatives ; Un Grand Bravo et au Nom de nôtre Belle Langues Française un Grand Merci à Vous :)
- (2023-02-09) Max: Incredibly slow support in the event of the application not working correctly, 4-5 day reply times with completely copy pasted information that is not specific to your issue.

- (2023-01-16) Shailesh pathak: For the past three months, I have been utilizing Outwrite as a writing tool and I must say, I have been thoroughly impressed. I used to believe that an extension's worth was solely based on its popularity and high rating, but I have come to realize that it is not the number of users that determine its value, but rather how well it can be utilized. Outwrite has proven to be a valuable asset in my writing journey, not only by helping me make my writing grammatically correct, but also by providing me with the tools to improve my writing style and all of this for free. I am truly grateful to the Outwrite team and cannot express enough love and appreciation for their hard work and dedication. Thank you, Outwrite!

- (2022-09-20) D Gardner: What happened? Outwrite was amazing. It's grammatical corrections helped and the readability statistics were spot on. But something changed and now it isn't accessible and is no where near as helpful.

- (2022-07-07) Wesley King: Wonderful :thumbs_up: I use it all the time. The Google Docs extension is extremely useful and the fact that it can proofread anything you write anywhere you write it is just great. Very well done, Outwrite team! You have created a product I'd actually pay for if I had money :). I especially like that it still tells you that you did something wrong, even when you're using the free version and don't have access to the fix. I'm usually able to just improvise until it stops yelling at me. I've shared this with my friends and they use it as well. I would personally continue using this over Grammarly, especially with the statistics bar on the side.

- (2021-11-14) Darcy Irvine: This is my absolute favorite writing app. It is incredibly useful and has helped me with my paper and essays in school. Not only does it correct my punctuation and spelling, but it suggests different ways to word a phrase or choose a better word to use. Outwrite is absolutely amazing, 10/10 I would absolutely recommend this app to everyone.
