Let AI Search, Read, and Work on Web Pages

Cumbersome has three web tools. Web Agent keeps a visible browser attached to the active chat for work that takes several steps. Local Web Search finds pages through DuckDuckGo, Bing, or Baidu. Local Web Browser reads one URL and can run one JavaScript action first. Requests come from your device, and the conversation shows what each tool did.

The answer can cite pages opened after a search.

Why run it on your device

Server-side search and browsing usually come from shared data-center IP addresses. Sites often answer that traffic with CAPTCHAs, rate limits, or outright blocks. Cumbersome sends the request from your own network and a real WebKit browser on your iPhone, iPad, or Mac. The site sees your network's IP address and the browser characteristics of an actual device instead of a generic cloud crawler.

It's private by architecture. Your device connects directly to the search engine or website. Folding Sky never proxies the request or receives the query, URL, or page contents through a backend. The search engine or site still sees the request, and your selected AI provider receives the result snippets or extracted text it needs to answer.

Keep one browser open with Web Agent

Web Agent keeps the current page and browsing history with the active chat. You can watch the page, scroll or type yourself, take over when a site needs human input, and then let the model continue from the same page.

The browser uses a nonpersistent WebKit data store. Closing Web Agent, disabling it, or leaving the chat discards that session. This limits what remains on the device afterward. It does not stop a website or your selected AI provider from receiving information while the session is open.

Search the web

Local Web Search takes search terms and returns result titles, URLs, and snippets. Choose DuckDuckGo, Bing, or Baidu as your Preferred Search Engine in Settings. Cumbersome tries it first for every search.

If it times out or returns an unusable results page, Cumbersome tries the others. Each gets up to eight seconds. Baidu stays last unless you choose it first. The tool row names the engine that worked and tells you when Cumbersome used a fallback.

Open and read a page

Local Web Browser starts with an exact URL. It opens that page through your device and returns readable page text to the AI. It works whether Local Web Search is on or off.

When a page needs an interaction before its content appears, Local Web Browser can run JavaScript once after loading and before reading the page. This works in visible and headless modes.

Choose the browser mode that fits the work

Use Web Agent when the work takes several steps or you want to interact with the page. Local Web Search and Local Web Browser start fresh for each request and can run without an open browser window. With both enabled, the model can search first and read the useful results instead of relying on snippets.

Headless mode can handle up to three independent searches or page loads at once. Web Agent stays sequential because each action depends on the state left by the one before it.

  1. 1Enable Web Agent, Local Web Search, Local Web Browser, or the combination you want in Settings.
  2. 2If search is enabled, choose DuckDuckGo, Bing, or Baidu as the Preferred Search Engine.
  3. 3Ask Cumbersome to work through a site when you want Web Agent. Ask for a search or provide an exact URL when one request is enough.
  4. 4Watch and interact with Web Agent, or expand a local tool row to inspect search results, extracted text, or a JavaScript result.
  5. 5Check the linked sources before relying on a time-sensitive answer.

Keep the tool trail instead of hiding it

Each search, page open, and extraction appears as a tool event. The result is easier to audit because you can see which sites contributed to the answer. This is especially useful for research that requires several sources rather than a single opaque search summary.

Searches, page loads, and extraction steps stay visible in the conversation.
Search and page browsing are separate tools. Turn on either one or both.

What to know before you use it

  • Web Agent, Local Web Search, and Local Web Browser require iOS 26, iPadOS 26, or macOS 26.
  • Search engines and other sites can block automated requests, require a login, or render content the extractor cannot read.
  • Search snippets and extracted page text are sent to the AI provider you selected so it can answer.
  • When Web Agent is signed in, the model can receive page data read from that session. Watch the current domain and actions, and avoid highly sensitive accounts.
  • A cited source can still be wrong or out of date. Open important sources and verify them.
