Idea Tiles
Brainstorm on-device, private
Free · Designed for iPad. Not verified for macOS.
Start with one thought and expand the space around it with on-device intelligence. Each tap sketches six new directions. Merge, filter, export; explore concept space.
Turn one idea into a map of everything around it.
Idea Tiles is a hexagonal brainstorming canvas 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 holding a single thought. Every tap pushes outward from there, expanding the conceptual space around your idea until the canvas holds its whole neighborhood: the obvious next steps, the odd angles, the connections you wouldn't have found staring at a list.
Four verbs do the work:
• Expand: tap any tile and the on-device model 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, JPG, SVG, or JSON, or pick up where you left off across sessions.
Private by default on iPhone and iPad.
On supported devices (iPhone 15 Pro, iPhone 16 and later, or an M-series iPad with Apple Intelligence enabled), tile expansion runs on Apple's on-device Foundation Models. Your prompts and ideas never leave the device. There is no cloud fallback: if the model isn't available, the app says so instead of quietly sending data elsewhere. No accounts, no analytics SDK, no tracking IDs.
Share a board.
Boards live on your device. When you want one out in the world, export it as a PNG, JPG, or SVG image, or as JSON, straight from the share sheet: AirDrop it, message it, save it to Files.
Built to feel fast.
Smooth pan and pinch on the canvas, undo/redo for every move, keyboard shortcuts for the iPad-with-keyboard crowd, and proper accessibility labels for VoiceOver.
Requirements:
• Tile expansion needs Apple Intelligence (iOS 26 or later) on eligible hardware.
• Everything else (canvas, merge, star, filter, export) works 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.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
Apple Intelligence detection is far more reliable: the app no longer reports it unavailable while the model is still warming up after a reboot or system update, and it re-checks automatically whenever you return to the app.
Template customization now runs on-device, matching every other generation path on iPhone and iPad: your prompts never leave the device.
New: export boards as JPG, alongside PNG, SVG, and JSON.
Refreshed app icon and splash screen. Feedback welcome: luke@lukesteuber.com.
