It seemed pretty clear to me from the description that this thing will let scripts read from Chrome to, e.g., pull in names from what you are looking at on LinkedIn and also make web requests.

But OP and Text Blaze should take your question as great feedback: by simplifying to "programmable snippets", it sounds like just a dumb automation tool to reduce typing. We saw that stuff yesterday on HN with people using AutoHotKey and similar.

Make it more clear what you offer!
