SAN FRANCISCO, May 7 — Ask Claude a factual question on a paid plan from this week on and the answer will usually arrive with sources attached. Anthropic turned on integrated web search by default Wednesday for Claude.ai subscribers on the Pro and Team tiers, the company told Consumer Tech Wire.
The move puts search-augmented chat in the base product rather than in an add-on, the position ChatGPT and Perplexity already occupy. What Anthropic is emphasizing is less the feature than the rules around it: citations by default, and a registry that lets publishers say yes or no.
For people using Claude
The practical change shows up in ordinary queries. A question Claude would previously have answered from its training data alone will now typically come back with two to four citations to current web pages. When a response draws on a search result, it carries an inline citation, and the cited URL is listed at the foot of the response.
Two limits apply. Search is not part of the Free tier in this rollout, and Anthropic would not say when, or whether, free users will get it. And the switch-on is gradual: the company said every eligible account will have it within 72 hours.

For publishers
Here the release adds work. Publishers who manage AI crawlers will now track three Anthropic user agents instead of two, and a single opt-in/opt-out registry governs all of them:
| User agent | What it does |
|---|---|
Claude-Web | Browses on behalf of a user during a conversation (existing) |
ClaudeBot | Collects training data (existing) |
Claude-SearchBot | Crawls pages for the search index (new) |
The registry decides whether a publisher’s content can appear among the citations in Claude search results. Anthropic first used the same pattern in 2024 for the ClaudeBot training crawler, and it is extending that approach rather than inventing a new one.
“The defaults matter,” an Anthropic spokesperson said in a written statement. “We want Claude search to be useful to readers and useful to publishers in roughly equal measure. Citation-by-default is the floor on that for the foreseeable future.”
How it compares
Anthropic is the third of the big assistant makers to make search a baseline. OpenAI enabled ChatGPT search by default in late 2024, and Perplexity launched its Pro Search tier in April. OpenAI’s crawler expansion drew publisher objections, which we covered in OpenAI Expands SearchGPT Crawler, Drawing Publisher Pushback.
Against that backdrop, an analyst at a consumer-publishing trade group described Anthropic’s combination of default citations and an opt-in registry as the most explicit publisher-facing policy framework so far.
“We’ve been telling members for a year that AI search is going to happen with or without their input,” the analyst said. “Anthropic’s framing is the first one that gives a publisher a clear yes-or-no choice and a transparent set of consequences for either answer. That’s a meaningful step.”
What to watch
Three questions remain open after the launch: when the Free tier gets search, how many publishers opt in once the registry covers citations as well as training, and whether citation-by-default holds up as answers get longer. Earlier in the year Anthropic shipped Claude Opus 4 with extended thinking on by default; search is the second default change to Claude.ai in 2026.
