Human questions. Practical software.

Our projects

Four ideas, one belief: software should meet people where they actually are.

ADaHaD

Understand more.
Judge less.

ADaHaD turns what caregivers observe into calm, evidence-grounded next steps — never a diagnosis, never a label. Every suggestion is cited to a clinical source, so support stays trustworthy instead of guesswork.

CKare

From learning to living.

SharpTong

Ask the elegant witch.
Get the truth, unsugared.
