About this project
A Chrome extension that adds a second chat column showing only the Twitch messages worth reading. ibai, 74,000 viewers, recorded 2026-09-19, played at 3x. Helpful, then Questions, then Funny. You need Chrome and a TypeSafe key. No account with us, no build step. Unzip it. You get a folder called extension. Turn on Developer mode. The switch is in the top right. Open any live Twitch channel. Click the gear in the Jev Chat column on the right. (You can also use Details, then Extension options.)

Highlights
- Intent chips filter live chat into Helpful, Questions, Funny, Feedback, or Everything meaningful without rewriting messages.
- Install is an unpacked developer-mode load; key testing and intent switching happen inside the added column.
- Spending stops at a configurable hourly cap, and switching intents re-sorts cached messages at no extra cost.
- Key stays in browser-local storage and is sent only to the Jev endpoint; host permissions cover Twitch and the API only.
Watch out
Chrome only with no Firefox build, one channel at a time, and relevance scores do not establish factual truth. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
Message text and usernames from the watched channel plus channel name, page title, and recent message context go to the Jev endpoint under your own TypeSafe account; video is never sent.
The author measured about 504 input tokens per message, with an hourly spend cap that pauses calls and says so in the column instead of silently falling back to a local heuristic.
That warning is expected for any extension loaded unpacked outside the Web Store; this project has no store build yet, so developer mode is the documented path.
Assessment is rate-capped by default, emotes render as text, and Twitch may change its IRC endpoint or limits at any time since the read-only connection is the same one web chat uses, not a contract.
Download the latest release zip, unzip it into a folder called extension, open chrome://extensions, turn on Developer mode in the top right and choose Load unpacked. Open any live channel, click the gear in the Jev Chat column on the right, paste your TypeSafe key and click Test key, which should report a model id and a round trip in milliseconds. Then reload the Twitch tab and pick an intent chip. Zero dependencies, no build step, Node 22 for development.
Measured on a live channel on 2026-09-19 with jev-1.13.0, a 20-message batch used 10,075 input tokens, about 504 per message, at $0.042 per million. That puts a 2 messages per second channel near $0.15 an hour, and a 50 per second channel at $0.76 an hour under the default 10 per second assessment cap, which the default $0.50 cap stops after roughly 40 minutes. Raising the cap to 50 per second runs about $3.81 an hour.
Chrome only, no Firefox build, and one channel at a time because the column follows the tab you are on. Install is developer mode until it reaches the Chrome Web Store. Emotes render as their text with no Twitch artwork shipped. Twitch can change its IRC endpoint or limits at any time, since the read-only connection used here is the one web chat uses rather than a contract. MIT licensed, and a relevance decision is not a claim of factual truth.
