Linguix Reviews

I have purchased numerous tools on AppSumo, and this one stands out as one of the best of 2025. It significantly enhances my writing, especially in languages other than my native tongue. While it continues to improve, it does experience occasional issues with my native language. Nevertheless, I am optimistic about its future development and growth.

I originally contacted Linguix after my lifetime plan showed as expired—even though I had redeemed multiple codes through AppSumo and made additional upgrades directly. I sent several emails with all the proper documentation, but support never responded beyond one vague message.

Eventually, my account was reactivated—but I was never notified or acknowledged. No confirmation, no follow-up, nothing.

I'm glad access was restored, but the experience left me frustrated. The tool itself is solid, and I’ve used it for years. But if something goes wrong, you might be left guessing whether your issue is even being looked at.

Works really well with no apparent bugs. Helps me correct grammar and spelling. But most useful is the ability to rephrase and rewrite content, that is much improved. Great app, thank you!

There is a perpetual loop when installing the app on iOS. After reviewing another user's question here, the founder claims that:

"It supports, but we were not able to update the app for the latest iPhones due to the focus being on the browser extension as our main product."

Had I known it was intended to be a browser extension only, I would have never purchased.

Absolutely unusable. I have tested it extensively in a business context. The browser add-on hangs constantly, sometimes it works, sometimes not and shows inexplicable reactions on some pages. The grammar check for non-English speakers is poor. Translations, every other program on the market is better. I am very dissatisfied.
