### How it works

Usually, webpage scripts can’t call methods or functions of browser extensions.

The Grammalecte API is injected within your webpage, with methods launching events that Grammalecte is listening. When Grammalecte receives one of these events, it launches the requested tasks. Results may be sent via events on webpage nodes.

For information purpose only, here are the layers of code explaining with you can’t access directly to the grammar checker:

    <> Grammalecte API (injected by the content-script, callable by the webpage script)
    <> Content-script (injected by the extension, not callable by the webpage script)
    <> Background script (extension core)
    <· Worker running the grammar checker on a different process
