Anthropic Settlement Portal Goes Live: Authors Can Now Search and File Claims

The landmark $1.5 billion Anthropic copyright settlement has reached a critical milestone with the launch of its official claims website. Authors whose books may have been pirated to train Anthropic’s AI systems can now search a newly released database of eligible works and file claims directly through the online portal.

How It Works

The site allows rightsholders to search by title, author, publisher, or ISBN. If a match is found, the search tool provides the book’s U.S. Copyright Office registration number, which is required to submit a claim.

A detailed FAQ explains how the massive list of allegedly pirated works — estimated at 7 million downloads from Library Genesis (LibGen) and PiLiMi — was narrowed to 482,460 titles that qualify for settlement payments.

The breakdown is striking:

• Roughly 3 million files were duplicates.

• 2.5 million works were in languages other than English, and most lacked U.S. copyright registration.

• That left 1.5 million English-language works, many of which were not registered or failed to meet the required registration timelines.

Why the List Differs from LibGen Searches

The FAQ notes an important distinction between this official database and other publicly available LibGen datasets, such as the one compiled by The Atlantic. Anthropic’s downloading activity stopped in July 2021, while LibGen has continued to evolve, adding many titles since then.

Filing a Claim

Authors ready to file will need to provide contact information — including an email for their publisher. However, the FAQ does not clarify who exactly should be listed as the publisher’s point of contact, and further guidance is expected from class counsel.

The launch of the claims portal represents a tangible step forward for authors seeking compensation after years of litigation. For many, it’s the first time they’ll be able to verify whether their work is directly tied to the historic settlement.

Thank you for contacting Class Counsel about the Anthropic settlement. We’re pleased to share that on September 25th, the Court granted preliminary settlement approval. Preliminary approval means the Court has preliminarily found the proposed settlement to be fair, reasonable, and adequate, has authorized official notice to the Class, and has allowed the settlement website and claims process to begin.

The settlement website is now live at www.AnthropicCopyrightSettlement.com. There you can read more about the settlement (including a detailed FAQ), review the Court-ordered notice regarding the settlement, and search the Works List. If you are a Class Member, you can submit a Claim Form online. The “Works List” is the database of books included in the settlement; for each work it includes the title, author(s), publisher, an ISBN and/or ASIN, and the U.S. copyright registration number. You can look up your book on the site to see if it is included and, if so, file your claim.
