Each tool only reads or calculates. History and copied text start off.
Quick grammar fixes
Clean up a reply before you send it, for a tiny fraction of a cent.
Fine print, fast
Summarize page after page for about a twentieth of a cent each.
What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
OpenRouter lists Claude Haiku 5.5 at $0.10 for a million input tokens and $0.50 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 36,000 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 1.1x what you see here, and your OpenRouter activity page shows what you were actually charged.

Claude Haiku 5.5, answered
Is Claude Haiku 5.5 available in UtilEngine today?
Yes. It is in the list as claude-haiku-5.5 and calls anthropic/claude-haiku-5.5 through OpenRouter with OpenRouter's :nitro speed routing, which the extension uses for every Anthropic model.
What does Claude Haiku 5.5 cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists Haiku 5.5 at $0.10 per million input tokens and $0.50 per million output, so a page summary costs about a twentieth of a cent. The extension routes for speed, so a faster route can serve the request at up to $0.11 per million in and $0.55 out. Prompts over 100,000 input tokens bill at a long-context rate of $0.50 in and $2.50 out, up to $0.55 and $2.75 on the fastest route. Each reply shows the tokens it used, not counting web searches.
What changed from Claude Haiku 4.5?
Anthropic says it costs about 75% less on average, runs faster, and scores far higher on its computer-use tests. Haiku 4.5 stays in the list, so a command set to it keeps running on it until you change it.
Do I need a Claude subscription?
No. Haiku 5.5 runs on your OpenRouter key, not a Claude plan. One key reaches it and the other 88 models in the list.
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.
