Show HN: Textyle Is a Universal Web Annotator Based Around Groups and Channels (textyle.io)

Hi everyone! My name is Kyle, and I built Textyle originally as a way of adding my own business and engineering context on top of the online documentation that I used every day. I was using the Amazon CDK documentation often and thought it would be useful to mark it up to avoid my and my team's repeated questions by opening up question threads directly on the source of truth.

Annotations are made on a layer on top of the web and are anchored there by matching XPath and text. They are organized into groups similar to Slack workspaces and Discord servers and are also separated into channels.

After having built the product, candidly, I'm not sure what the best use case for a tool like this is, but I thought I would show it to you!
