Handwrite and draw straight into Claude — math, equations, and graphs by pen, finger, or mouse. Made for tablets and touchscreens. Summary / short description: Handwrite and draw straight into Claude — math, equations, graphs by pen, finger, or mouse. Made for tablets and touchscreens. Detailed description: Peinard adds a pen to Claude. Some things are easier to write than to type — a fraction, an integral, a quick graph, a chemical equation. Peinard lets you write or draw them by hand and drop them straight into your Claude conversation, where Claude reads them directly. No typing math, no OCR mangling your notation. How it works Open any chat on claude.ai and click the purple Write button. Write or draw on the pad — pen, finger, or mouse. Hit Insert to place it in your message (send when ready), or Insert & send to do both in one tap. Your handwriting lands in the chat as a clean image, cropped to what you drew, and Claude responds to it like any other message. What's inside Pen and eraser, each with its own remembered thickness, plus five ink colors Graph-paper grid you can toggle for plotting and neat work Pinch to zoom; two-finger drag or hand mode to move around the page A big sheet with room in every direction, and an endless canvas that keeps unrolling as you write down the page Undo and redo (Ctrl+Z / Ctrl+Shift+Z) — a slip doesn't mean erasing Snapshot: copy your work to the clipboard and paste it anywhere A movable, resizable, see-through pad, so you can read the question behind it while you work Made for tablets and touchscreens — a Surface, a touchscreen laptop, anywhere you'd rather write than type. Works just as well with a mouse on the desktop. Peinard runs entirely in your browser. It collects nothing, stores nothing, and sends nothing anywhere — your handwriting goes only into your Claude chat, and only when you choose to insert it. Peinard is built by Turbojad.
