Brand voice

Writer is focused on business writing. The extension will work on any website and mailing service to help your employees stick to your tone of voice.

Different guides for different departments

You can create several organizations, write different guidelines for each of them, and choose the necessary one from a drop-down menu.

Google Documents support

Writer Chrome Extension works with Google Document the same way it does with other text editors on other websites and pages.

Spelling and grammar checker

Besides general spell checking, Writer supports custom guidelines and terms to personalize your company’s writing style.

Development Challenges and Solutions

How our team coped with a range of development challenges

Working with Google Documents


Google Documents’ editor is far from usual. It has complex logic and structure. Besides, the Google Documents service is going to use canvas instead of HTML, and it makes text processing even harder.


We are adapting the Chrome extension to canvas to facilitate spell checking.

Working with Google Documents

Highlighting mistakes


Writer Chrome Extension calculates the positions of wrong words and phrases by their coordinates. When the words’ positions are changing or new text appears, the coordinates need to be recalculated.


We created an algorithm that completes this task and now our team is working on its upgrade.
