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, every surface.

Web editor

The full workbench: corrections, transformers, agents, entities, dictionaries, analytics.

Open the editor

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

Every text box on the web, from CMS to social dashboards. Rated 4.9 on the Chrome Web Store.

Chrome Web Store

Microsoft Edge

The same extension installs and runs in Edge unchanged.

Add to Edge

Firefox

The same extension and engine for Firefox users.

Firefox Add-ons

Google Workspace

Docs, Gmail, Slides, Forms, and Sheets: native support for the Google surfaces many teams live in.

Workspace Marketplace

WordPress

Check posts and pages inside the editor, before anything publishes.

Windows desktop

System-wide checking in any application, including Teams.

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.

lisan-sdk.js

<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 and English alike. One assistant that proofreads, enforces your style, and explains every correction, wherever your teams write.
