Linguix: Free Writing Assistant (in dev.)

Brand Story

Linguix is Free Writing Assistant. It’s a SaaS product with Russian-originated founders dedicated to the improvement of the writing capabilities of its users all over the world.


Build a smooth, high-quality & stable mobile application based on AI-algorithm the service is using currently. The one interesting point is that the final solution should be not the regular app, but a utility application vastly connected with the user keyboard.


Build quality mobile applications from scratch using the existing AI-based backend & combine everything smoothly in utility keyboard application for App Store & Google Play.

We kicked off the process with technical specification development for the product, outlining priority functionalities & parts of the product, working on the design of the service, clearly setting up the environment for the development & focusing on the most important parts of the product development.

Native iOS & Android development languages — Swift & Kotlin respectively — were chosen for the development of the application — since it’s a keyboard utility app with certain platform-specific functionalities.

Backend API was provided from the client’s end since they already had a web-based product built — so we were just implementing that.


The service is in the development at the moment — we’re finishing some parts of it & polishing the whole product to respond to quality standards of the service — at the end of the day, Grammarly is the main competitor of the company.

Product Plans

Future plans are clear & simple — improvement of a current version of the application, iterative process of gathering user feedback & market response in order to beat the competition & gain a foothold on the market.
