Before Linguix, Grammarly had been correcting me since 2013. So, I have seen Grammarly at their early stage and when they started, they were not even close to where Linguix is today. Linguix is in a notably advantageous position at an early stage. Linguix offers features that aren't even present in Grammarly even after years. Grammarly grew up just because it got our support this is what Linguix is looking for from us. I have Microsoft 365 subscription; I can use Microsoft Editor, but I choose Linguix for the following reasons.
1. Deal price!! You are getting three subscriptions at $49, that makes it around ~$16 each licence. (You don't even get a single month Grammarly subscription at this price, so comparing it with Grammarly would be very unfair)
2. Snippets: this one is my favourite feature. I often have to do repeated texts to my clients and team members. Before Linguix I'll have to paste it from the Windows Clipboard or the sticky notes but now getting them right into my text editor is just a shortcut away.
3. Secret Mode: We often share our account/computer with our friends and family, if you use the secret mode you won't have to be worried about anything that is auto saved and left in your account.
4. Beautiful UI and choice of colours, colours are energetic and eye catching. Overall, I find UX amazing. No matter what I see Synonyms, Style, Statistics all are easy on the eye. Dashboards are beautiful and informative; they give writing insights about everything that makes you feel confident.
6. Templates: IMHO this feature alone is worth the price I have paid, I often search for email templates, and read them all and design one for each occasion and it consumes a lot of time. Linguix comes here for the rescue with their cool templates feature, you can use and customize existing templates or create your own that can be inserted anytime right from the Linguix.
7. In my knowledge, I think Linguix is the only writing assistant that not only focuses on writing but also your writing productivity and who doesn't like productivity tools for their team?

I have talked a lot about the Pros, it doesn't mean that Linguix is perfect. It has Cons too which you want to consider before buying this deal
1. Not as good as Grammarly but again it is not a fair comparison(I strongly believe if they got the right audience with the right feedback and our support, one fine day they may become better than Grammarly).
2. No plagiarism checker, but I saw in the roadmap that they have planned it for November. (Fingers Crossed)
3. Linguix app is SPA (single page application), but not the dashboard.
4. My native language Hindi (~322 million native speakers in the world) is missing from the list in the settings.
5. No markups in the document editor, this is something I feel is very important. Please consider adding it.

Verdict: To Be Continued...
