Quadrats let researchers sample organisms within defined areas, making abundance estimates more consistent across a habitat.

Supporting excerpt: “Quadrats define repeatable sample areas for estimating organism abundance.”

How to chat with a PDF

To chat with a PDF, sign in to GoodOff, upload the document to your library, and ask questions in plain language. Sage retrieves relevant excerpts from the uploaded source, answers from that context, and shows the source excerpts used with the response.

PDF to Chat FAQ

Can I ask multiple questions about the same PDF?+

Yes. After the PDF is processed in your library, you can ask follow-up questions in the same Sage conversation.

Are the answers based on my PDF?+

The grounded chat workflow retrieves relevant excerpts from your uploaded source and instructs Sage to answer from those excerpts. If the retrieved source does not contain the answer, Sage is instructed to say so.
