Karaoke for your Tesla.
Real Spotify, word-by-word on the big screen. No cover bands, no fixed catalogs. Just you, your playlist, and the open road.
Not affiliated with Tesla, Spotify, or Apple Music.
Not a lyrics viewer. A karaoke machine dressed up for the Model S.
Your music. The real recordings.
Belter hooks directly into your Spotify library — the originals, with the artists you love. No re-recordings, no fixed catalogs, no compromises. If it's in your Spotify, you can sing to it.
Word-by-word, lit up.
Each word brightens on the beat. The same effect as Apple Music Sing on iPhone — finally on your Tesla's 15-inch screen.
Drive Mode · Party Mode.
In motion? Minimal, calm, passenger-friendly. Parked at a charger? Big fonts, album-art washes, confetti on the chorus.
Duet split-screen.
Shallow. Summer Nights. Don't Go Breaking My Heart. Left side, right side — nobody trips over whose line is next.
K-pop, J-pop, reggaeton.
Romanization for every non-Latin script. Sing Korean without reading Korean. (Premium.)
Works on every Tesla. Zero install.
Model S, 3, X, Y, Cybertruck. Open the browser on your Tesla, type the URL, start singing. No app store to wrangle. No software update to wait for. If Tesla's browser can load a webpage, Belter works.
Everything your Tesla has. Plus everything it's missing.

We show the lyrics. We don't touch the audio.
Belter doesn't process or remove original vocals — that'd be out of scope and honestly, worse quality than what Apple already ships. On Apple Music, enable Apple Music Sing on your iPhone (Settings → Music → Sing) and cast via Bluetooth — you'll get vocal attenuation for free. On Spotify, the vocals stay as-is. You're singing with the song, not over it.
Sing free. Or don't stop.
For the casual singer-along.

Frequently asked.
Yes. Belter syncs to your currently-playing Spotify track in real time, which requires a Spotify Premium subscription — free Spotify accounts don't support real-time playback state via the API. Apple Music support is planned for a future update.
Belter has a built-in Drive Mode that activates automatically when your car is in motion — minimal text, dimmed styling, passenger-friendly by design. You'll see a safety confirmation on first use. Party Mode only activates when parked.
No. Belter is a web app. You open your Tesla's browser, go to belter.pro, log in with Spotify, and start singing. Nothing to download, nothing to update.
All of them with a browser — Model S, Model 3, Model X, Model Y, and Cybertruck. Requires MCU 2 or newer (any Tesla from 2018 onwards).
Everything except word-by-word highlighting, unlimited songs, and translation. You get 5 songs per day (with a 25-per-week cap so power users can't stretch it) with full Spotify support at launch and both display modes. It's genuinely usable forever. No trial pressure — the free tier is permanent.
Belter displays lyrics beautifully — it doesn't process audio. If you want to lower the vocals on Apple Music, enable Apple Music Sing on your iPhone (Settings → Music → Sing) and play via Bluetooth. For Spotify, the vocals stay as-is. You're singing with the song, not over it.
Private beta is open now to waitlist members. Spotify ships first — we'll email you the invite when it's ready. Apple Music support is planned for a future update.
