SDIT Tools · Free & Open Source

Tools built for the age of AI.

Free software from the San Diego Institute of Technology — simple instruments for attention, understanding, privacy, and taste.

No cost. No tracking. No lock-in.

The ToolsFive Apps

Simple instruments, plainly made.

Each tool does one thing well, costs nothing, and keeps nothing of yours. The source for every one is public.

Focus

One button, a calm countdown, a daily goal that compounds into deep work. Discipline over motivation. iOS & macOS.

Shade

See what your phone gives away, harden it, keep sensitive files in an encrypted vault, and — for members — route traffic through a no-logs VPN. On-device, no account. iOS.

The Gallery

Your television becomes an art gallery: one spotlit work at a time, music from the moment it was made, and the full story on a placard. Apple TV.

Roadmap

More are coming.

These five are the beginning — each made for the same reason: a person should meet the computer in a way that strengthens the mind rather than dissolves it.
