## What its pages say

Quoted word for word from grammarly.com's own pages.

- In their own words: “Grammarly is built on a simple belief: anyone can communicate effectively and persuasively with the right tools. Clear communication fuels results that speak for themselves, whether in a winning sales pitch, an essay that makes the grade, or a message that strikes exactly the right tone. Our linguists and researchers work at the frontier of natural language processing and generative AI, with one goal in mind: to help people write with more clarity, more confidence, and a voice that's entirely their own.” (https://www.grammarly.com/about)
