The Apps

Two Helpers for One Busy House.

Both are still being built. Here is what each one is meant to do.

Coming Soon to Mac

Paper Butler

Meet Filbert. He uses AI to read every bill, letter and form you scan, gives it a proper name, and suggests the right folder. He tells you when he isn’t sure, and he never moves a thing without asking.

  • Reads your papers on your Mac by default
  • Clear names like “2026-10 Electric bill”
  • Says if he is Certain, Fairly sure or Guessing

In Development · Coming 2027

Mirai Canvas

Turn a tablet or spare screen into the family’s home base. Calendar, weather, chores, dinner and photos, big enough to read from across the kitchen.

  • Everyone’s day in one place
  • Runs on screens you already own
  • AI helpers for the family plan are being explored

Our Promise

Built Like We’d Want It for Our Own Family.

Your Stuff Stays Yours

We keep your family’s information on your own devices wherever we can. We never sell it.

Easy for Everyone

If a grandparent can’t figure it out in a minute, we haven’t finished the design.

No Ads, No Tricks

No ads and no surprise upsells. You always know what you’re paying for.

The Company

Made by C9 Mirai.

Our apps are made by C9 Mirai LLC, a small family company in Pennsylvania. “Mirai” means “future” in Japanese. We want the future at home to feel a bit calmer.
