Local-first spatial canvas

Think in space.

Features

A canvas that works the way your brain does

Everything you need to map, structure, and ship your thinking — nothing you don't.

∞

Infinite spatial canvas

Pan, zoom, and arrange freely — or snap to a grid with automatic overlap resolution. Free-form and grid modes, one tap apart.

↝

Fluid connections

Draw living bezier lines between cards. Connections inherit the source card's color, so relationships read at a glance. Tap again to unlink.

◈

Color as meaning

Five card themes with an editable legend — define what obsidian, terracotta, aubergine, gold, and void mean for your system.

✦

AI Synthesis (BYOK)

One tap sends your board's structure to DeepSeek and returns an executive synthesis: hierarchy, blind spots, next actions. Bring your own API key — you pay the provider directly, we never see it.

⇩

Export everything

JSON (re-importable), human-readable TXT, a copy-paste AI constraint prompt, and PDF export of syntheses. Your data is never locked in.

☾

Built for real life

Dark mode, autosave, undo history, live Markdown in cards, and full touch support — drag, pinch-zoom, and swipe on any phone or tablet.

How it works

From noise to structure in three moves

01

Capture

Add a card for every thought, task, or fragment. Write in Markdown — bold, lists, headers render live as you type.

02

Connect

Drag lines between related cards and color-code by meaning. The shape of the problem emerges from the map itself.

03

Synthesize

Run AI Synthesis for a structured brief of the whole board — or export JSON, TXT, or a ready-made AI prompt.

FAQ

Questions, answered straight

Where is my data stored?
Entirely on your device, in your browser's local storage — and only after you accept the storage notice. Nothing is uploaded to us; there is no server, no account, and no analytics. Export JSON backups anytime.
Is Pro really a one-time payment?
Yes. You pay once, get a license key instantly, and unlock unlimited cards on that device. No subscription, no renewal, no locked features appearing later.
What does AI Synthesis cost?
MindCan uses a bring-your-own-key model with DeepSeek. You create a key at platform.deepseek.com and pay DeepSeek directly for usage (typically fractions of a cent per synthesis). Your key is stored only on your device and sent only to DeepSeek.
Does it work on phones and tablets?
Yes — MindCan is built mobile-first: touch drag, two-finger pinch-zoom, swipe-to-dismiss panels, and a dock that adapts to small screens. It works in any modern mobile browser.
Can I move my work between devices?
Yes. Export your canvas as JSON on one device and import it on another — spatial layout, colors, and connections are fully preserved.
What's your refund policy?
Purchases follow the refund policy of the store you buy through (Stripe or Gumroad). If something's broken, contact support and we'll make it right.
