Working from your own material.
WHY THIS MATTERS
When the model works from a document you provided, the answer comes from that text rather than from training data.
That is the most reliable way to use any AI assistant.
WHAT YOU CAN DO
Ask questions about a document Summarise it Extract specific information Compare documents Have it explained in plain language
HOW TO ASK
"Answer only from the document I uploaded. If something is not in it, say so."
That instruction reduces the model supplementing from general knowledge.
USEFUL FOLLOW-UP
"Quote the passage supporting your answer."
Lets you verify immediately.
WHAT AFFECTS RESULTS
Document quality. A poor scan produces poor extraction. Length. Very long documents may need splitting. Structure. Complex tables are handled imperfectly.
WHAT TO VERIFY
Every figure you will act on, against the original.
WHAT NOT TO UPLOAD
Anything you have not established is appropriate to send.
