What it is
A bring-your-own-key Chrome extension for Twitch viewers. It reads a channel's live chat over the anonymous IRC WebSocket and adds a second column showing only the messages matching a chosen intent: Helpful, Questions, Funny, Feedback, or Everything meaningful.
How it uses Jev
Jev makes one category Choice per chat message, sent in batches of 20. State includes the message text, username, channel name, page title, and the last 12 message texts as context. Results filter the second chat column; clicking a row shows the full probability distribution, category and model id.
Primitives:choice
Technique worth stealing
Batch 20 messages per Jev call; switching intent re-sorts results you already have, at no extra cost.
Try it
Download the release zip, Load unpacked the extension folder, paste your TypeSafe key, reload the Twitch tab, pick an intent chip.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
