Idea Tiles

View ideas as tiles, then expand, merge, and share them using the on-device intelligence on supported iPhone models. No cloud, no account, no tracking.

Use onboard intelligence to turn one idea into a whole canvas.

Idea Tiles is a hexagonal brainstorming app for anyone who thinks in fragments — writers chasing a stuck chapter, designers mapping a flow, indie product folks scoping the next feature, students breaking a topic into pieces. You start with a single tile. From there, four verbs:

• Expand — tap any tile and the AI sketches six related directions around it. Branches keep their context, so the third ring still knows what the first tile was about. • Merge — drag two tiles together and the app synthesizes a new one that captures what the pair share. • Star — mark key themes and filter the canvas to just those threads when the board gets dense. • Export — save a board as PNG, SVG, or JSON, share a link, or pick up where you left off across sessions. • EXPERIMENTAL: Link your canvas between devices and collaborate with others.

Private by default on iPhone and iPad. On supported iPhones (iPhone 15 Pro, iPhone 16 and later, or an M-series iPad with Apple Intelligence enabled), tile expansion uses Apple's on-device Foundation Models. Your prompts and ideas never leave the device. There is no cloud fallback on iOS — if the model isn't available, the app tells you instead of quietly sending data elsewhere. No accounts, no analytics SDK, no tracking IDs.

Built to feel fast. Smooth pan and pinch on the canvas, undo/redo for every move, keyboard shortcuts for the desktop and iPad-with-keyboard crowd, and proper accessibility labels for VoiceOver.

Requirements. • AI tile expansion needs Apple Intelligence (iOS 26 or later) on eligible hardware. • Other features — canvas, merge, star, filter, export, snapshot share — work on any supported iPhone or iPad. • If your device can't run Apple Intelligence, you'll see a clear message instead of a confusing failure.
