Highlights

What you get

Proof / status

Dex is where Hastie & Co tests careful companion-app patterns in public.

Dex is shared as a public experiment, not a commercial product. It stays deliberately cautious around source material and ownership.

Point of trust

Structural trust, not vibes.

Public pages say what is real now, how to get help, and where the edges are. No vague fog, no pretending unfinished things are finished.
