Everything for the perfect night
Built for the whole room
TesseractDJ turns any room into a karaoke bar, a video night or a request line — no apps to pass around, no waiting on one person's phone.
Find the right version
Search by song or artist across every genre and era — and land on a clean, singable karaoke version instead of digging through a pile of duplicate re-uploads.

Karaoke or music videos
Not everyone wants to sing. A full music-video catalog sits beside the karaoke one — browse it by genre or theme, or paste in a playlist link — and both share a single running order, so a video and a song can go back to back. When the last video is up, the rotation pulls a related one and keeps going instead of parking the TV on a board.
The room joins in
Cheers and emoji rain down the edges of the video while someone's mid-song, with the sender's name along for the ride. There's a soundboard, post-song awards, Karaoke Roulette, trivia rounds between singers and a raffle you enter by taking part — and guests' selfies land on the big screen.

Every finished party becomes its own private page — setlist, photos, trivia scores and who sang what — at a link that's yours to keep or send on.

Run a real karaoke show
On Mac, TesseractDJ becomes the whole production. Plug into your TV or projector and it drives the night — so you can actually sing too, instead of babysitting a playlist.
-
Seamless transitionsEvery song plays to its real ending, then hands off to the next singer — no dead air, no scrambling for the next video.
-
A live info boardBetween songs the big screen shows who's up next and your own shout-outs — a branded board, not a paused YouTube tab.
-
Trivia roundsRun multiple-choice trivia between singers. Guests answer on their phones; the answer count and leaderboard update live on the TV.
-
Transition musicDrop in your own playlist to fill the gaps between performers, so the room never goes quiet.
-
Latecomers scan in mid-showThrow the join code up over whatever's on screen — a song, the board, a slideshow — so someone who just walked in gets in without you cutting away.
New · for DJs
Not karaoke tonight? Take requests.
Flip TesseractDJ into request mode and the crowd becomes your request line. Guests scan a code, search any song, and send it to your booth — and the requests drop right into the set you're already spinning.
-
Requests from every phoneGuests scan a QR and search a massive catalog right in their browser — no app to install, no shouting song names over the speakers.
-
Straight into your crateEach request is matched against your own Serato library, so you drop it into your queue in a tap — or wave it off. Your set, your call.
-
Read the roomRequests get an "on vibe / off vibe" read based on what you've already played, so you can keep the floor moving instead of guessing.
-
Tips & shout-outsPut your Venmo on the big screen for tips, and let guests send shout-outs that rotate on the board — with light moderation so nothing weird makes the TV.
-
Your own request boardA branded screen shows the scan-to-request code, a live request feed, guest photos and trivia — a real display for the room, not a Notes app on a TV.
DJ Pro · Mac
Your Mac is the booth.
Everything above runs from one Mac window, plugged into the TV and the PA. This is the half that isn't a party app — a real audio chain, real levels, and the unglamorous things that keep a paid gig from falling over.
iPhone and iPad host a party just fine. The Mac runs a business.
01
A real audio chain
- Level Match YouTube turns loud tracks down and never turns quiet ones up, so an under-mastered upload sits several decibels below the rest of your night. One switch sets a constant per-song boost — measured from where the music actually starts, so a long spoken intro can't fool it — and arms a safety limiter with it.
- Analog VU meters Switchable between the feed going into the show and the output going to the PA, reading against the limiter so you see the overs your own effects add.
- An Audio Unit rack Four inserts, your own plugins, editor windows and saved presets. Off until you switch it on, because scanning every installed plugin is a cost paid at show start.
- Live key control Shift any song up or down in real time to fit whoever just grabbed the mic — no octave jump mid-song.
02
Show control
- One lineup, karaoke and music videos Search both catalogs from one pane, drag either kind, and the order you set stays set instead of being re-derived under you.
- Smart Shuffle Re-deal everything still waiting at a ratio you choose — two videos for every song, say — leaving whatever is on air exactly where it is.
- Hand-offs paced by the song that's ending A karaoke track plays its outro out under the board; a video just stops. The show finds where the audio really ends and cuts there rather than playing out somebody's silent tail.
- Intro skip Skits, stories and film-style cold opens get cued past. Confident marks apply themselves; anything less certain is only ever offered, because clipping the first bar is the worse mistake.
- Boards you design Lay out the between-songs screen yourself, and throw the join QR over anything that's live — song, board or slideshow — without cutting away from the show.
03
Venue-proof
- Connection Check Measure the venue's link before doors and get one concrete recommendation you apply in a tap. Never automatic, and it asks first if a show is already running.
- Offline videos Pre-download the night and play from disk — the answer to a venue whose Wi-Fi can't be trusted.
- Low Data Mode Every bandwidth lever on one screen in the order you'd reach for them, plus an uplink readout that tells you when you're on a hotspot and should go find a cable.
- Lookups run on your Mac Video search, playlist expansion and intro detection happen on your machine rather than from one server address shared by every gig at once. If your own link is the weak point, a switch hands the work back mid-gig with no restart.
04
The business end
- Every party recaps itself Setlist, timeline, trivia results, guests, shout-outs and photos render into a private keepsake page the next morning — ready to send to whoever booked you.
- Requests land in your crate Each one is matched against your own Serato library, so it's one tap to queue it or wave it off. Your set, your call.
- Tips and shout-outs on the big screen Your Venmo on the board and guest shout-outs in rotation, with light moderation so nothing weird makes the TV.
- The night is archived every ten minutes Closing the laptop without pressing End Party doesn't cost you the recap.
- Safe for the family gigs Guests are asked their age once, and anyone under 13 sings and queues like everyone else while their photo, last name and notifications are simply never collected.
