# The Browser-Discovery Tax Every time an agent re-drives a website's interface, it pays a tax that produces nothing reusable. A browser-first agent that checks the same dashboard a hundred times performs the same DOM parsing, the same element lookups, the same retries, and the same language-model reasoning a hundred times. The published research calls this the browser-discovery tax: the recurring cost of rediscovering a workflow that has not changed. None of that work is saved for the next run, so the hundred-and-first visit costs exactly as much as the first. This matters because agent workloads are repetitive by nature. The same small set of tasks (read this inbox, list these events, fetch this price) runs over and over across many agents, and a browser-first design pays full price each time. Removing the tax does not require a smarter model; it requires not redoing solved work. Unbrowse exists to collect that solved work once and hand it back cheaply, which is the subject of the next page. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.unbrowse.ai/start-here/the-browser-discovery-tax.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
