# How to add a spell-checker for Crisp messages

*Add a browser spell-checker to the Crisp web app so your team can catch typos and grammar mistakes before sending messages.*

Crisp works well with browser-based writing assistants. If you want extra help while writing replies, the easiest option is to install a spell-checker extension in the browser you use for **https://app.crisp.chat**.

| The tools below are third-party extensions. You can use any spell-checker you prefer, as long as it supports your browser and language.

[Grammarly](https://www.grammarly.com/) is a popular option for English writing. Once its browser extension is enabled, it can review the text you type in the Crisp editor.

# ${color}[#0080dd](Choose the tool that fits your language)

Grammarly and MerciApp are simply two well-known examples. If your team writes in another language, you can use a different browser spell-checker instead.

The main thing to check is that the extension supports your browser and works correctly inside the Crisp editor.
