Work in motion · Est. 2026

The core distinction

Two modes, one brand

Everything we publish is tagged for the mode you are actually in. Blur them and you get a listicle that gets someone hurt.

Driving

Driving mode

You are responsible for the vehicle. Voice-first, glance-safe, interruption-tolerant. Grok, CarPlay, Android Auto, phone over Bluetooth.

Think out loud, capture, rehearse, dictate
No reading, no typing, no lists to choose from
Supervised autonomy still means supervision

Riding

Riding mode

Camera on, keyboard out, headphones in
Constraints are bandwidth, privacy, motion sickness
Where the tooling is thinnest and the upside largest

The test: are you legally the driver right now? If yes, you are in driving mode. There is no third option and no partial credit. Read the full split →
