In short. The new Claude experience removes the toggle because Claude decides when web search helps.
Definition: The missing web search toggle is part of Claude's new conversation interface. In that interface, Claude decides when web search helps and invokes it automatically, while the earlier interface lets a person turn web search on or off.
Key facts
- Anthropic's web search help says the new Claude experience has no web search toggle and that Claude searches the web when it helps.
- Claude's new experience documentation says chat and Claude Cowork are merged into one conversation, with no mode to choose.
- Anthropic's release notes place the new experience rollout on 16 September 2026 and say it is rolling out gradually to Pro and Max plans on web, desktop, and mobile.
- In the older interface, a person can select Web search from the plus button and turn it off again from the same menu.
What changed in the new interface?
The new Claude experience combines chat and Claude Cowork in one conversation. Claude's documentation says that a person can ask for a quick answer or a larger task without choosing a mode first. Web search is one of the capabilities Claude can select as it handles the request.
The rollout is gradual. Anthropic says it began with Pro and Max plans on web, desktop, and mobile, and that more plans will follow. If the message box still shows separate “Chat” and “Cowork” options, the account remains on the earlier experience. Once the account moves to the new experience, the separate options cannot be restored, according to the same documentation.
How does automatic search work?
Claude's web search help says that Claude invokes a search tool when a question benefits from current information. It processes multiple sources and returns a conversational response with direct citations and source links. During a search, the interface shows an indicator that Claude is searching the web.
The help page also documents a prompt-level instruction for cases where web search should be used:
Search the web
The same page says that a prompt can ask Claude not to use web search. Search and web fetch count toward usage limits, and search availability can vary with connectivity. These controls affect a conversation's request; they do not restore the missing toggle in the new interface.
How can you identify which interface is active?
Look at the message box. The Claude Cowork and chat documentation uses the presence of separate “Chat” and “Cowork” options as the marker for the earlier experience. Their absence indicates the new experience. The older web search workflow places a Web search item in the plus-button menu, where a checkmark appears when the feature is enabled.
For a website owner, the relevant distinction is how Claude may reach current pages during a conversation. The help page says that web search responses include citations and source links. It also says that, when Web search is toggled on in the older interface, Claude can retrieve the content of a page supplied by direct URL through web fetch.
