Open toolWhy we build free tools
The best way to understand a thinking tool is to use one. Every tool here solves a real problem on its own — map an idea, prioritize a day, study for an exam, clear a cluttered mind — with no account and nothing to install.
They also share a philosophy with OmniCanvas: your thinking should be visual, connected, and yours. When a quick tool isn't enough — when you want your work synced across devices, organized into folders, linked together, and waiting for you next time — that's what OmniCanvas, the infinite spatial second brain, is for.
Put it all on one infinite canvas
Capture everything, link anything, and visualize your thoughts on a canvas that never ends. Free to start — no credit card.
