A 3D cork board in your browser — pin photos, notes, clippings and fingerprints, then tie them together with living red string that sags, swings and settles like real yarn. Every case stays on your device.

Drop in any image — it becomes a glossy printed photograph with a white border, a pin, and a shadow. It never leaves your machine.
Handwritten scraps in four colors, with folded corners. Double-click to scribble.
Typewritten suspect, location and note cards with red-ruled headers — stamped like the real thing.
Torn newspaper headlines for the morning the story broke.
Procedurally-whorled print cards, no two alike.
Full undo/redo across moves, pins, edits and string. Boards save locally, automatically.
Most tools draw connections as flat lines. Redstring simulates every thread as a chain of ~50 particles under gravity — so it sags between pins, whips when you fling a photo, swings past its mark, and settles like a real thread on a real board. Drag anything and watch the whole web react.
Writers plotting novels, TTRPG game masters running mysteries, true-crime enthusiasts, researchers mapping sources, product folks tracing dependencies — anyone whose thinking looks like “things on a wall, connected by string.”
Yes. Redstring is a static page — there is no server. Photos and notes are stored in your browser only. Nothing is uploaded, ever.
Pro is verified directly on-chain in your browser: send ~$24 of ETH on Base (an Ethereum L2 — fees under a cent, confirms in seconds) or Ethereum mainnet, paste the transaction, done. No processor, no account, nothing stored about you.
It's WebGL — any reasonably modern laptop or desktop runs it at 60fps. The physics sleeps threads that aren't moving, so big boards stay smooth.
