Company
Textly Inc.
Linguix is developed by Textly Inc. and targets professionals, sales teams, marketing departments, and customer support agents who need to write efficiently and consistently across digital channels. The product positions itself in the productivity software segment, offering both a free browser extension and paid business plans with team management capabilities.

Linguix distinguishes itself from general grammar tools by combining multilingual support, a content quality scoring system, reusable shortcuts, and corporate style guides in a single platform.
