About
The thinking canvas that lets you outwin.
Outwin is a fast, frictionless whiteboard for engineers who work with AI — sketch your system, then export a diagram Claude or ChatGPT understands instantly. It runs entirely in your browser, costs nothing, and never asks you to sign up.
Why we built it
Engineers think on a canvas. We sketch boxes, draw arrows, jot the messy version of an idea, then talk it through. But the moment you want help from an AI, the canvas falls apart: every other tool hands you a flat PNG. The model sees pixels, not your system — so it can't reason about the architecture you just drew.
Outwin fixes that. An export isn't a screenshot; it's plain, open HTML that carries a machine-readable description of every box, link, and note. Drag it into Claude or ChatGPT and the model sees the whole picture — ready to generate Terraform, review the design, or write the docs. The same export still renders as a clean diagram for humans, so one file works for your teammate and your model alike.
Who it's for
Outwin is built for the people who sketch a system one minute and hand it to a model the next.
Forward-deployed engineers
Walk into a customer's stack, map it on the canvas in real time, and leave with an artifact your AI tooling can pick up where the meeting left off.
AI engineers
Diagram the agent graph, the RAG pipeline, the tool-calling flow — then drop the export straight into a prompt so the model reasons about the system you actually designed.
Solutions architects
Reach for 1,100+ official AWS, Azure, and GCP icons to draw cloud architecture that looks right in a review and reads right to an LLM.
Anyone who diagrams, then hands it to an LLM
If your workflow ends in a chat box, Outwin meets you there. No format wrangling, no "describe this image for me" — just a diagram the model already understands.
What makes it different
AI-readable by default
Every export is something an LLM can read directly — open HTML with a structured description of each box, link, and note. No converting, no screenshots, no plugins.
A real icon library, built in
1,100+ official cloud icons — 302 AWS, 628 Azure, 216 GCP — plus 660 tech and brand logos. Type /aws, /azure, /gcp, or /brand to drop in the exact one you need.
Frictionless to use
Press / for a command menu — text, boxes, lists, code, icons, link cards, images. Ghost-suggestion pills branch one idea into ten, and smart auto-layout keeps everything from overlapping as it grows.
Private by design
No account, no server. Outwin runs entirely in your browser and your boards live in local storage — nothing is uploaded, ever. After the first load it even works offline.
Free
No trial, no paywall, no catch. Open the canvas and start drawing.
By the numbers
How a session goes
From blank canvas to something a model can act on takes about three moves.
-
1
Open the canvas and start drawing
No setup, no sign-in. Press / and drop in boxes, lists, code, or cloud icons. The board saves itself to your browser as you go.
-
2
Branch the idea
Ghost-suggestion pills offer the next box or note; accept the ones that fit and the smart auto-layout reflows everything so nothing overlaps. One idea becomes ten without you fighting the canvas.
-
3
Export and hand it off
Save AI-readable HTML for Claude or ChatGPT, or a crisp PNG for the deck. Same diagram, whichever audience is next.
The name
Outwin lives at outw.in, and the wink is on purpose: winners win, legends outw.in. The "O" is an eye — a thinking canvas that's watching the idea take shape with you.
Local-first, on purpose
Because Outwin runs in your browser with nothing uploaded, your napkin-math architecture stays yours. Clear your storage and it's gone — no copy on a server, no telemetry trailing behind it.
