Keryx — Ask & pay creators

Ask Keryx about a question or text you select on a page. Read a cited answer, follow the research trace, and inspect recorded payment evidence. Choose Quick or Deep research, optionally include the displayed page URL, or search scholarly sources. Open the full hosted report, export references in BibTeX, RIS and CSL-JSON, or export evidence CSV. Reopen up to ten recent completed public reports on this device. Questions, submitted selected text and research results are public. Submit only information you want published. An optional account-claim action can save eligible completed anonymous reports to your account; it does not make the published research private. Hosted server admission and sponsorship limits apply. Model and search costs are separate from source spending. The extension contains no wallet signer. Stop watching disconnects the popup and does not promise to cancel server work. Creator registration and account workspaces open on the Keryx website. Privacy policy: https://github.com/tang-vu/keryx/blob/main/docs/extension-privacy.md
