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.

Extensive support

Writer works with many services and apps: Google Chrome, Figma, Microsoft Word, and Contentful.

Spelling and grammar checker

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


A snippet lets you insert big frames of text with a simple shortcut. If you need to write repetitive texts like introductory emails, this function is for you.

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.

Work with Google docs

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.

Hightkighting mistakes



When we were working on the highlighting feature, there were no detailed instructions on how to correctly implement it in the documentation.


We studied TypeScript’s definitions for the Figma API and experimented with several options that can potentially work.
