Attach files with the + button in the composer, or paste — a screenshot on your clipboard pastes straight in. Pasting is not gated by analyst: paste an image while Dave is selected and he’ll say he can’t read it — switch to Deb and ask again. Then ask against them the way you’d hand a document to an analyst: “from this 10-K, what changed in segment reporting?”
PDF, CSV, TXT, Markdown, and XLSX with every analyst. Quantesta extracts their available text for Dave, Sam, and Deb. JPEG and PNG attach when the analyst with image vision — Deb — is selected. See Analysts.
Quantesta extracts the complete available text; there is no separate 100,000-character file cap or 200,000-character message cap. If the full request would reach the context boundary, the turn is refused before the analyst runs instead of silently cutting or skipping an attachment. For very long filings, scope the question (“the risk factors section”) or start a fresh chat.
Attach several documents to one message — a set of quarterlies, or a filing plus your own notes — and ask across them. Quantesta extracts every supported document; their combined text remains subject to the same context boundary as the rest of the conversation.
