Everything starts in the input row at the bottom of a chat. This page walks it left to right — every control, and the keystrokes behind them.
Click + to attach files: PDF, CSV, TXT, Markdown, or XLSX with any analyst. Image files (JPEG, PNG) appear in the picker only when the selected analyst has image vision — Deb.
Pasting works too: a screenshot on your clipboard pastes straight into the composer as an attachment. One honest caveat — pasting is not gated, so you can paste an image while Dave is selected; he can’t read it and will say so, and the fix is to switch the analyst and ask again. Details on file handling in Documents & uploads.
The Cmd button (short for command) opens two groups: Functions — the system functions, /memo (write a document into the side panel) and /sheet (build a spreadsheet into the side panel) — and Skills, holding your saved skills, the built-in starters, and skill creation. Pick an entry and its instruction lands in the composer. What skills are and how to build them: Skills.
The chip showing the current analyst’s name opens the selector. Each row shows the analyst’s credit cost and three small icons: the wrench means live data tools, the eye means native image vision, the brain means deep reasoning. PDFs and other supported documents are extracted to text for every analyst. Dave has no eye — that’s the one to check before an image-heavy session. Who the analysts are: Analysts.
Type /as the first character in an empty composer and Quantesta’s command line opens. It holds, in order: your own skills, the starter prompts (including /skill-creator), the system functions — /memo (write a document into the side panel) and /sheet (build a spreadsheet into the side panel) — and /skill-new.
Keep typing to filter. Arrow keys move the selection; Enter or Tab applies it; Esc closes the menu. /memo and /sheet are the fastest route to a downloadable document — see Artifacts & exports.
Enter sends. Shift+Enter starts a new line without sending. While the analyst works, the send button becomes a stop button — stopping halts the run server-side and keeps whatever was already written.
Hover over any question you already sent and a pencil appears. Click it, and the text returns to the composer for correcting — Enter sends the fixed question and the analyst answers it afresh; Esc abandons the edit. A copy button sits beside the pencil.
The prompt tiles on the home screen are ready-made asks — click one to run it. The same starters live in the / menu, and they can be customized from the Skills page.
