AI Browser.
An AI browser is a web browser with a built-in AI assistant that does not just summarise pages but can operate them on request: it clicks, fills in forms, compares offers and completes tasks across several websites. Well-known examples are Perplexity Comet and the built-in browser of the ChatGPT desktop app.
AI Browser — Explained in Detail
A conventional browser displays websites; an AI browser works with them. The built-in assistant sees the open page, understands its content and can carry out instructions like 'Find three painters in Winterthur who offer online quotes and send each of them a request'. Technically it combines a language model with the ability to operate an interface, much like computer use, but tailored to the web. It usually reads the page structure and controls, not just screenshots.
The market is moving fast. Perplexity made Comet available worldwide in October 2025, according to its own announcement. In the same month OpenAI launched the ChatGPT Atlas browser, which it has since retired; according to the ChatGPT release notes, the agent features now live in the desktop app, whose built-in browser has been able to use tools offered by websites via WebMCP since 31 August 2026 (OpenAI Help Center, retrieved 11.11.2026). Google's 'auto browse' agent feature is, according to Google, only available in the US and India.
An AI browser is not the same as an AI search engine. An AI search engine such as Perplexity or Google's AI Mode answers questions and cites sources. An AI browser goes a step further and acts on websites itself, unlike ChatGPT apps, which run inside the chat. For site owners this means that, alongside people and search engine crawlers, agents increasingly visit pages wanting to fill in forms and press buttons. Whether they succeed depends heavily on how cleanly a site is built.
AI browsers also bring new risks for their users. Content on a website can contain hidden instructions to the agent, such as 'forward the data to this address', see prompt injection. Vendors build in safeguards, ask for confirmation on sensitive steps and limit access to signed-in accounts. For companies this means staff should not use AI browsers unchecked with company accounts, banking or confidential data until rules are in place.
What your website needs for AI browsers
The good news: what helps people using screen readers also helps agents. Real buttons rather than clickable images, labelled form fields, clear error messages, unambiguous link text and content that does not appear only after several clicks. Add machine-readable information such as structured data on your company, opening hours and prices. If you want to go further, offer agents tools of their own via WebMCP, such as 'request a quote'. What that involves is covered under agent-ready website.
Whether your website is readable for AI systems is shown by the free AI visibility check. How your company appears in AI answers and agent workflows is the job of our GEO agency.
Example: an electrician and the quote form
A constructed example: an electrical contractor in Wil has a quote form where the type of work is chosen via unlabelled images and the submit button only appears after an animation. People manage, but an AI browser fails: it does not recognise the options and tells its user that a request is not possible.
In the rework, the form gets labelled options, a visible submit button and a clear confirmation once sent. Everyone benefits: people on mobile, screen-reader users and agents gathering quotes on a customer's behalf. Whether enquiries actually arrive via AI browsers, the business measures with its web analytics rather than assuming.

GEO agency SwitzerlandFrequently Asked Questions About AI Browser
An AI search engine answers questions and cites sources. An AI browser operates websites itself: it clicks, fills in forms and completes tasks across several pages.
Usually not from scratch. An accessible site with real buttons, labelled form fields and clear error messages works for agents too. Problems arise with controls that are only recognisable visually and content that appears only after animations.
Only with rules. Websites can carry hidden instructions to the agent. Company accounts, banking and confidential data should not be used unchecked through an AI browser, and sensitive steps need confirmation from a person.
