mytesla.io vs Hey Grok
Grok lives in the car for questions and navigation; mytesla.io lets any AI run your Tesla's climate, charging, and security remotely. How they differ and why they work together.
Tesla now ships Grok in the car — say "Hey Grok" and you can ask questions and set navigation without touching the screen. That's a real step forward, and it raises an obvious question: if my Tesla already has an AI, why would I use mytesla.io? The short answer is that they solve different problems, and they work well together.
mytesla.io is an independent service and is not affiliated with, endorsed by, or sponsored by Tesla, Inc. or xAI. Grok's capabilities change with each software update — check Tesla's release notes for what's live on your car.
What "Hey Grok" does
As of 2026, Grok in the car is primarily a conversational co-pilot:
- Answers questions ("how far to the next Supercharger?").
- Sets and adjusts navigation by voice.
- Lives in the vehicle, tied to your car's AI hardware.
Tesla has said deeper Full Self-Driving voice control is coming. But Grok is built around the driving experience, from the driver's seat.
What mytesla.io does
mytesla.io connects your car to the AI assistant you use everywhere else — Claude, ChatGPT, Cursor — so it can run real commands remotely and compose them with the rest of your life:
- Pre-condition climate before you leave the house.
- Set charging to hit a target by a departure time, on off-peak rates.
- Check status, locks, and windows from your laptop or phone.
- Combine the car with your calendar, the weather, and your smart home in a single request.
It's a Tesla MCP server exposing 40 Fleet API tools — climate, charging, access, security, navigation sharing, software updates.
Side by side
| Hey Grok (in-car) | mytesla.io | |
|---|---|---|
| Where it runs | Inside the vehicle | Anywhere your AI is — laptop, phone, desktop |
| Main job | Questions + navigation while driving | Running the car remotely + automations |
| Climate / charging control | Not the focus today | Core feature (40 tools) |
| Calendar / weather / smart-home logic | No | Yes — composed by your assistant |
| Which AI | Grok only | Claude, ChatGPT, Cursor, any MCP client |
| Works before you get in the car | No | Yes — that's the point |
They're complements, not competitors
The natural setup: Grok for in-car voice and navigation, mytesla.io for everything you want to happen before and after you're in the seat.
- On the couch: "Claude, make sure the car's charged to 90% and warm by 7 AM." → mytesla.io.
- In the driver's seat: "Hey Grok, take me to the office, avoid the highway." → Grok.
Neither one replaces the other, and using mytesla.io doesn't disable anything Tesla ships.
Why not just wait for Tesla to add all of this to Grok?
Maybe it will. But mytesla.io works today, works from outside the car, works with the AI you already pay for, and composes with your other tools — calendar, weather, Slack, smart home — which an in-car assistant tied to Tesla's stack isn't positioned to do. If your day runs through Claude or ChatGPT, that's where you want your car too.
FAQ
Does using mytesla.io interfere with Grok? No. They're independent. Grok is Tesla's in-car assistant; mytesla.io is an external MCP service. Both use the car through official channels.
Can Grok pre-condition my car from home like mytesla.io? Today Grok is centered on in-car questions and navigation. Remote climate and charging automation composed with your calendar is what mytesla.io is for.
Do I need a specific Tesla to use mytesla.io? Any Tesla that supports the Fleet API and Vehicle Command Protocol (roughly 2018+ Model S/3/X/Y) — Grok's newer-hardware requirement doesn't apply.
