Use Kimi K3 in Chrome
Moonshot AI calls Kimi K3 the first open 3T-class model, built for long-horizon coding, knowledge work, and reasoning. One shortcut on any page, your own OpenRouter key, provider prices.
Get it for $49What Kimi K3 is good at
Three jobs it does well from the launcher, and what comes back when you run them.
Why code does what it does
Open a repository page and ask why the code there does what it does.
What it can read
Each tool only reads or calculates. History and copied text start off.
Research pages in one pass
Summarize a long research page and keep the method, the results and the limits apart.
Threads in another language
Translate a long thread written in another language in one request rather than message by message.
What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
OpenRouter lists Kimi K3 at $2.70 for a million input tokens and $13.50 for a million output tokens. A page of text is a few thousand tokens, so most of what you do in a browser costs cents, not dollars.
At list price a $20 month buys about 1,300 long-article summaries. You are not buying a month, though. You pay for the tokens each job uses, and the rest of your OpenRouter balance just sits there.
The extension asks OpenRouter for the fastest route, which can be a faster route at a higher rate than the one this receipt is priced on. When that route wins, the same three jobs cost about 1.7x what you see here, and your OpenRouter activity page shows what you were actually charged.

Kimi K3, answered
Is Kimi K3 available in UtilEngine today?
Yes. It is in the list as kimi-k3 and calls moonshotai/kimi-k3 through OpenRouter with OpenRouter's :nitro speed routing.
What does Kimi K3 cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists Kimi K3 at $2.70 per million input tokens and $13.50 per million output, which puts a page summary under two cents, and Moonshot AI's own route lists $3 and $15. The extension routes for speed, so a faster route can serve the request at up to $4.50 per million in and $22.50 out. Each reply shows the tokens it used, not counting web searches.
Do I need a Moonshot AI account?
No. Your OpenRouter key covers Kimi K3 and the four other Kimi models in the list, and the credit lives in your OpenRouter account.
Can I use Kimi K3 for one command and a cheaper model for another?
Yes. Each AI command stores its own model, so Kimi K3 can run Translate To while Fix Spelling and Grammar stays on the cheap default.
Does the AI act on pages?
No. Every tool it can call reads, from page text and your selection to your tabs and the web, and each call shows as a chip in the answer. It never clicks, types or submits a form.
Kimi K3, one keystroke away
Chat, Ask AI, and your own commands on any page, in a launcher with 50+ built in.
One-time payment. 14-day refund, no questions asked.
