A method for providing writing assistance features in a web browser or native application including an embedded web browser, the method comprising:

• detecting that a webpage has been rendered by the web browser;
• analyzing a structure of the webpage to determine a topology of the webpage by accessing a Document Object Model (DOM) of the webpage and traversing the DOM of the webpage to identify nodes comprising the webpage to determine the topology of the webpage;
• construct a model of the webpage based on the topology of the webpage, wherein the model of the webpage is configured to automatically monitor the topology of the webpage and to update the model based on detected changes to the webpage;
• detect, using the model, a change in textual content of an input element of the webpage;
• obtain annotation information associated with the textual content on the webpage;
• and
• render the annotation information over at least a portion of the webpage displayed by the web browser.
