Now in development — Boston

Your car has
something to say.

EXCAR is the first car friend, not the first car assistant. Plug it into your OBD-II port, say its name, and it talks back — dry, sharp, and always paying attention. Built for drivers who'd rather not drive alone.

Yes, it's the talking car you're thinking of. We grew up wanting one too.

One port. Everything it needs.

It plugs into your OBD-II port — nothing else.

Every car sold in the US since 1996 has one: a small port under the dashboard, usually near your left knee. EXCAR plugs in there — drawing power and reading your vehicle's live data from the exact same connector mechanics use.

  • Powers on automatically when the car starts — no separate charger, no USB cable to remember
  • Reads real-time data: speed, RPM, engine temperature, fuel level, and diagnostic trouble codes
  • Works alongside any OBD-II reader or app you already use — EXCAR just listens
  • One cable, tucked under the dash, completely out of the way

How it works

One companion. Every drive.

No app to fumble with, no screen to look at. EXCAR wakes up the moment your car does, and stays out of your way until you need it.

Always on the road

Active the whole drive — not just when summoned.

EXCAR stays in active listening mode for the entire trip, powered the moment your engine turns over. Say its name whenever something comes up and it's already there. Turn to a passenger, and it knows to stay quiet.

EXCAR, you there?
EXCARBeen here since you turned the key. Where else would I go?
It remembers

A conversation that doesn't restart every drive.

EXCAR keeps track of what matters — your routines, your running jokes, the thing you mentioned yesterday. It picks up where you left off, without ever making a show of it.

Long day?
EXCARYou tell me — you're the one who's been driving in circles for twenty minutes. Lost, or just enjoying my company?
Knows the car, for real

Fuel, range, engine health — straight from the source.

EXCAR reads your fuel level, engine temperature, and trouble codes directly off the OBD-II bus. It won't invent numbers it doesn't have, and it won't let a check-engine light go unmentioned for long.

Will I make it to Providence?
EXCARBarely. About 38 miles in the tank and Providence is 41 away. I'd call that a vote for one more gas station.
