Citations, now verified against the page

Every quote Sift returns is re-checked against the source PDF before it reaches you. If the text can’t be found on the page, the citation is dropped rather than guessed.

Notion and Drive connectors

Team notes now sit alongside papers in the same index. Permissions follow the source, so Sift only answers from what you could already open.
