The fast, frictionless whiteboard for engineers who work with AI — sketch your system, then export a diagram Claude or ChatGPT understands instantly. Other tools hand you a flat image; Outwin hands your AI the whole picture.
Press / anywhere on the canvas to add anythingReach toward any block and faint pills fade in along its open edges — a text block, a box, a list, or / for everything else. Click one and a connected child drops onto that side with the arrow already drawn, so you never break stride hunting for a tool. They only surface on open canvas with room to grow, then quietly step aside once a diagram gets dense.
/ for headings, to-dos, code & more1,100+ pixel-perfect AWS, Azure & GCP service icons are built right in — the real ones. Type a slash, grab S3, wire it to a Lambda, and you've got a diagram that actually looks like your system.
/aws, /azure or /gcp to drop a real service iconEvery text block speaks Markdown — headings, bold, lists and checkboxes form as you type. Paste a snippet of code and it drops into a tidy monospace block, ready to reference. Capture the messy thought now; it still reads clean later.
#, - and [ ] become headings, lists & to-dos as you type`code`, bold & italics while you flowHold S and just talk. Your cursor turns into a live listening waveform, your words trail behind it as you speak, and the moment you let go the captured text is held ready to place. Click once and it drops onto the board as a clean text block — no panel, no record button, no fuss. It runs on the browser's own speech engine, so works beautifully in Chrome and any browser that supports speech-to-text.
S and talk — the cursor becomes a live waveformPaste any URL and Outwin turns it into a clean link card — title, site and a tappable link. Park it right beside the flow you're sketching, so the source and the architecture thought it backs up sit on one canvas. They stay where you left them — easy to refer back to, never lost in a tab graveyard.
Hit laser mode and the whole board locks into a presentation. Your cursor becomes a glowing pointer with a fading trail — walk anyone through the system without ever leaving the page or fumbling for slides.
An Outwin export is plain, open HTML — not a locked, proprietary format only one app can read. So you can drop the file right into Claude or ChatGPT and start asking. No converting, no screenshots, no plugins. Attach it and chat.

There's no server, no account, no sync. Every board lives entirely on your own machine — your notes, links and diagrams never touch the cloud. It's the rare tool you can hand your most sensitive thinking without a second thought.
