Duni - Canvas for ChatGPT

Turn your ChatGPT conversations into a visual canvas. Instead of scrolling endlessly through a long thread, Duni places each response on an open canvas as a block you can move, arrange, and connect — so you can see the whole shape of your thinking at a glance. WHY DUNI Long ChatGPT conversations become hard to navigate. Important answers get buried, related ideas drift apart, and you lose the thread of where things branched. Duni gives your conversation a spatial layout: a mind-map view where structure becomes visible and nothing gets lost in the scroll. WHAT YOU CAN DO - Visual canvas — Each ChatGPT response becomes a block on a free-form canvas. Drag blocks anywhere, zoom in and out, and pan across your whole conversation. - Connect your ideas — Draw connections between blocks to map how thoughts relate, build branches, or trace a line of reasoning across the canvas. - Add your own notes — Drop sticky notes onto the canvas to capture your own thoughts alongside the conversation. - Highlight what matters — Mark and emphasize the parts of a response you want to find again. - Import & export — Save your canvas to a JSON file and bring it back later. Your work is portable and stays in your hands. - Light and dark themes — Switch the canvas to match how you like to work. PRIVACY FIRST Duni runs entirely on your own machine. Your canvas — blocks, notes, connections, and layout — is stored locally in your browser using IndexedDB. Nothing is ever sent to any server. No accounts, no tracking, no analytics, no telemetry. Duni only reads the conversation on the ChatGPT page to build your canvas, and it works on a single site: chatgpt.com.
