Tethr.

A voice in the passenger seat, for the drives that feel longer.

A warm voice companion for tired drives. Tethr keeps you mentally engaged, checks in on how alert you're feeling, and helps you notice when it's time to pull over.

Tethr is a companion, not a safety device. It does not detect drowsiness and cannot prevent accidents. If you feel unsafe to drive, pull over. Always. Read the full disclaimer.

How a drive with Tethr feels.

  1. 1

    Tell Tethr how long the drive is.

    It shapes the conversation around your trip and your pace.

  2. 2

    Talk about whatever you want.

    Your day, your shift, the people in your life. Tethr keeps the conversation alive.

  3. 3

    Check-ins, not interruptions.

    Every ten or fifteen minutes, Tethr asks how alert you're feeling on a scale of one to ten, where ten is wide awake and one is fighting to keep your eyes open. You answer with a number. That's it.

Get on the list.
