Anthropic rolls out Claude search across all paid tiers, with publisher-citation defaults

SAN FRANCISCO, May 7 — Anthropic enabled integrated web search by default for Claude.ai users on its Pro and Team subscription tiers Wednesday, the company told Consumer Tech Wire, joining OpenAI and Perplexity in offering search-augmented chat as a baseline feature rather than a paid add-on.

The rollout ships with two policy choices that distinguish it from the earliest waves of AI search products. Claude responses that draw on a search result include an inline citation to the source by default, with the cited URL surfaced in the response footer. And publishers can opt into a registry that controls whether their content is eligible to appear in Claude search citations — a pattern the company first established with its ClaudeBot training-data crawler in 2024.

“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.”

The Free tier of Claude.ai does not get search in this rollout. Anthropic declined to disclose timing for a Free-tier rollout.

For publishers, the registry change means three operational surfaces to track instead of two: the existing Claude-Web user agent for browsing on behalf of a user, the existing ClaudeBot user agent for training-data collection, and a new Claude-SearchBot user agent for search-index crawling. The same opt-in/opt-out registry covers all three.

The May rollout follows OpenAI’s enablement of ChatGPT search by default in late 2024 and Perplexity’s launch of its Pro Search tier earlier in April. Of the three, Anthropic’s citation-by-default plus opt-in registry is the most explicit publisher-facing policy framework so far, an analyst at one consumer-publishing trade group said.

“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.”

For users, the search-by-default behavior changes Claude.ai’s response surface in routine queries. A factual question that previously prompted Claude to answer from training data will now typically include 2-4 citations to current web sources. Anthropic said the change will roll out to all eligible accounts over the next 72 hours.
