### 5/5 — Love this tool

*2026-08-05, version 1.2.3*

Next to Grammarly, this is the best grammar program out there. It has one advantage of Grammarly. It doesn’t hold your hand in is a better program if you’re trying to learn how to ride on your own so go for it if that’s what you want is to improve on your writing skills. This is your app, although I’ve heard another writing app that may be better for your writing, although it’s not good all around it’s probably two hands off. Or something like that may be better, but this is the best all-around her.

### 1/5 — Save Your Moneyy

*2026-07-09, version v8.21.1*

I paid for the premium version after kicking its tires. It worked for a few months and then stopped. Now it doesn't catch anything in picky mode. Basic typos go unnoticed. Support wasn't terribly helpful. 

This is embarrassing, even if LT was some sort of half-assed open source project. Sad that the company does so little testing.

I decided to build a better mousetrap myself with Claude.

### 3/5 — Auf IOs unbrauchbar?

*2026-06-19*

Für den PC super. Auf dem iPhone und iPad pro mit Magic Keyboard unbrauchbar buggy, bei mir zumindest. Es geht auch immer durch den ganzen Verlauf einer E-Mail beispielsweise und hängt sich dann manchmal auf. Ziemlich nervig.

### 5/5 — Un Bescherelle au bout des doigts

*2026-05-14*

Je suis un maniaque de l'orthographe, mais ayant souvent la tête dans la lune, il m’arrive de ne pas faire attention. Grâce à cette extension clavier, je peux me corriger à la volée et en prime, ça m’explique la raison de mes erreurs. Cette application devrait être intégrée dans chaque clavier virtuel et c’est carrément incompréhensible que ce ne soit pas le cas !

### 5/5 — Really handy

*2026-04-28, version 1.2.3*

Im loving it

### 1/5 — Horrible.

*2026-03-28, version 1.2.3*

I honestly do not like this because when I try to sign up, it takes me to a reCAPTCHA page. And when I check the box it doesn’t even load. It makes me redo it over and over again just for me to not ever use the app. Please fix this.

### 1/5 — Première correction : une ÉNORME faute !

*2026-03-15, version v8.21.1*

Après avoir galérer une éternité à installer cette application, avoir eu des difficulté et des bogues à chaque micro-étape, me voilà enfin dans Word. Je lance la correction de texte et que vois-je ??? Il veut me corriger cette phrase : Une personne qui marche vite, qui semble pressée… par « Une personne qui marche vite, qui parais pressée... ».
Parait avec un S ! Oui, oui, cette chose insiste comme première correction pour mettre un S. Une personne qui PARAIS ? Pardon ? Suggérer « paraît » (avec un "s") pour s'accorder avec « une personne qui semble... », c'est une faute de grammaire flagrante. C'est gênant pour un correcteur.

### 1/5 — Ruim

*2026-03-05*

Não consigo me cadastrar para usar o app, porque fica abrindo a página da web que fica toda branca. Horrível

### 1/5 — Only works if you’re native to US

*2026-02-24, version 1.2.3*

Like the title implies. If you live in Australia, the editing keeps reverting back to US keyboard. Frustrating as ****

### 5/5 — Excelente

*2026-02-11, version 1.2.3*

Mágico
