Feature
In the tools your teams
already use.
Nobody switches apps to check a sentence. WriteX comes to the text: Office add-ins, browser extensions, Google surfaces, a Windows desktop app, and an SDK for your own systems.
Surfaces
One engine, nine surfaces.
Microsoft Word
A full task pane from AppSource: proofread the whole file, Correct All, double-click an error to jump to the word.
Get the add-in →Microsoft Outlook
Check emails before they leave. The same categories and style guide as the editor.
Get the add-in →Microsoft PowerPoint
Decks carry your brand as much as documents do. Proofread slides in place.
Get the add-in →Chrome & Edge
Every text box on the web, from CMS to social dashboards. Rated 4.9 on the Chrome Web Store.
Chrome Web Store →Google Docs & Gmail
Native support for the Google surfaces many teams live in.
Workspace Marketplace →Windows desktop
System-wide checking in any application, including Teams.
Web editor
The full workbench: corrections, transformers, agents, entities, dictionaries, analytics.
Open the editor →API & SDK
Two script tags embed WriteX in your own portals and systems; a REST API serves the pipeline cases.
For developers
Embed the engine in an afternoon.
The SDK initializes with a client ID and attaches to your editors; the API takes text and returns classified corrections. Both respect the same style guides your admins manage in the app.
<script src="https://app.lisan.ai/sdk/lisan-sdk.js"></script>
<script>
LisanClient.initialize({ clientId: "YOUR-CLIENT-CODE" });
</script>The live SDK: two tags and every text field on the page is checked. Client IDs come with institutional plans.
Frequently asked questions
Where do I install the Office add-ins?
From Microsoft AppSource, or directly inside Word, PowerPoint, and Outlook via the built-in add-in store. Search for Lisan, sign in, and the task pane is live.
Is there an API for batch or pipeline use?
Yes. The REST API takes text and returns classified corrections; the JavaScript SDK embeds live checking in your own web systems. Both are available on institutional plans.
Every word your institution writes, checked.
Official letters to social posts, Arabic to English to Spanish. One assistant that proofreads, enforces your style, and explains every correction, wherever your teams write.
