Attach a keyword export or an analytics report to a message — the assistant parses the table and can come back to it later.
A paperclip appeared in the input row: you can attach .xls, .xlsx or .csv files to a message. The file is parsed and its contents go into the conversation's context.
Files then became a proper part of the chat. Every upload is stored with a short summary, and the full text is injected only into the first message — in later turns the assistant knows the file is there and can pull it back in full when it needs the data again. That way a long conversation with a large table doesn't run into the context limit.
Anyone working with exports: Wordstat keyword sets, analytics reports, crawler page lists.
Click the paperclip in the input row, pick a spreadsheet and ask about it — "take a look at this keyword export", for example. Several messages later you can say "go back to that file" and the assistant will open it itself.
