Introducing Mosaic Space.
Your journal should be private, personal, and become something you can actually see.
Mosaic is fully native in Swift and uses Apple’s Foundation Models entirely on device. No accounts. No analytics. No data collected. Your journal stays yours.
Write about a moment, a thought, or your whole day. Mosaic reflects on each entry locally, understands its mood, and maps it to a color-driven tile.
Every entry adds another tile. Over time, they become an evolving visual record of your life.
The on-device model is intentionally quiet. It isn’t there to turn journaling into a chatbot. It reads between the lines, surfaces themes and reflections when there’s something worth saying, then gets out of the way.
But journaling isn’t only about looking back.
Mosaic also gives you a way to visualize the things ahead of you. A trip. A birthday. Graduation. Anything you’re waiting for. Instead of another date on a calendar, you can actually see yourself getting closer.
A way to appreciate where you’ve been and feel excited about what’s next.
Because everyone needs something to look forward to.
This is the way.
Reading this felt oddly familiar. I built an app around the exact same experience and shared it on Nostr five months ago.
Private, on-device journal reflection with Apple’s Foundation Models. No data collected, no accounts, fully native in Swift.
In my version, each journal entry’s mood is analyzed and mapped to a color-driven tile in an evolving mosaic.
Beyond that, the only difference is the paywall.
Mine is free.

Sharp changes in compute are exactly what the difficulty equation accounts for. A fork that isn’t popular will be too far behind the majority consensus by the time they mine 2016 blocks and are able to stabilize a 10m block time, but overloading the network with compute will only allow for faster block discovery over small epoch as it adjusts accordingly in the opposite direction too. Truly a masterpiece.
