Yes. On the Full version, singers request songs from the web app at https://singer.auto-kj.com/. They can search the songbook, see their place in line, and send a request. They find the show by GPS, a show code, or the venue LAN. They do not install an app from an app store. The Free version is desk-entered only.
Auto-KJ is karaoke host software for a live show. It runs on Windows, macOS, and Linux. Paul Kircher makes it. The host plays song files that stay on the booth computer. Auto-KJ does not include a licensed song catalog. Singer phones are a Full version feature, called cloud singer phones with the Social Engine on the site. Questions go to support@auto-kj.com.
How a singer requests a song
Singers open https://singer.auto-kj.com/ in a phone browser. The site describes that page as a web app (PWA). They do not install an app from an app store. The host app is the desktop download on auto-kj.com.
They reach the show in one of three ways already listed on the FAQ and the pricing section:
- GPS. The phone can find a nearby show. If location access is declined, a show code or a QR code still works.
- Show code. The singer types a show code. The pricing section calls this a 4-letter join code. The singer show code is not the email verification code used to start a trial.
- Venue LAN. The singer joins the local network and uses the phone browser there.
To join, the singer enters a show code or scans the host's QR code, and types a stage name. An account is not required. With the Full version, singers scan the QR code, find a nearby show, or enter the show code. The songbook opens in the phone browser.
From there, singers search the host's songbook and send a request to the booth. The host can review it, or turn on Auto-Approve. Extra songs wait in that singer's personal queue for later turns. Karaoke files stay on the host computer. The songbook stores artist and title metadata for search, not the audio or video.
The Full version also adds a walk-up kiosk and a phone remote. Any spare tablet becomes a walk-up request kiosk. Singers can preview a venue's songbook from home with the show code.
Lineup, wait, favorites, and duets
On the Full version, singers can check their place in line, see an estimated wait, and watch the same list from their phones. Estimates update as the show changes. Signed-in singers can turn on alerts that say when their turn is coming. The Free version does not include singer phones. The host still has the lyrics screen and the rotation screen.
Singers can search the songbook, request a solo or a duet, star favorites, and build setlists. An optional singer account stores favorites. You do not need an account to sing.
When a singer enters a duet or group song, tagged partners receive a push notification on their phones to accept or decline before the request touches the queue. In the rotation, duets wait in a side queue, then fuse into one slot so both names are accounted for. A late arrival takes the first seat that does not push anyone else back. A pause does not take the stage. A skip closes the gap. Changing the song keeps the singer's seat. The host can still drag anyone. Those rules are the Fairness Engine, written up on karaoke host software.
When the venue Wi-Fi is bad
Phone requests still need a network connection: either internet access or the local venue LAN. The Full version can fail over to a LAN in the middle of a show when the venue internet drops: the same rotation rules, local requests, and playback continues. There is no separate offline plan. LAN failover is part of the Full version. Cloud singer requests are not described as working with no network at all.
The host computer can run a local server. Singers connect from the phone browser on a network you control, such as a travel router, and browse the songbook without using the venue's internet. Cloud requests and GPS show finding work when the room has signal. The same show falls back to that local network when it does not. The rig is in karaoke in a bar with terrible Wi-Fi.
Paper slips and the Free version
The Free version is $0. It includes the desktop app, Fairness Engine rotation for songs entered at the desk, your own files, and a dual screen. It does not include singer phones. The download does not require an account. You still collect names and type them.
The paper form for that desk is the karaoke sign-up sheet and request slips. A printed sheet needs no venue Wi-Fi, no login, and no charged phone. The singer at the other end of the bar cannot see it, so the order is your word until you show the clipboard. A skip leaves a gap you close by hand. On the Full version, the slips can stay as a backup while singers request from the phone browser and watch the same order.
OpenKJ hosts who only want phone search
You can keep running OpenKJ and point its request server at Auto-KJ so singers search your songbook from a phone. That hosting is $5 per month or $50 per year on its own, and it is included with the Full version. It stores titles and artists only, and it does not unlock the Auto-KJ desktop app. That path is the OpenKJ alternative. Auto-KJ itself is a separate product. It is not built on OpenKJ, and it is not open source.
How phone requests compare
These rows use claims already published on Auto-KJ pages, plus the ordinary fact that a paper slip is something a person writes and hands to the booth. KaraFun and SongBookDB prices below are the figures on the comparison pages, not a new checkout quote.
| Paper slips | KaraFun Pro remote | SongBookDB-style request tool | Auto-KJ | |
|---|---|---|---|---|
| What the singer does | Writes a name, song, and artist on a sign-up sheet or request slip. The host types the row. | Uses KaraFun Pro's remote queue. The KaraFun comparison lists up to 100 connected. | Sends a request from a separate tool. On PCDJ Karaoki, SongBookDB is that subscription. A singer can send a key change. The host clicks the request into the rotation, or auto-accepts. | Opens singer.auto-kj.com in a phone browser, searches the host's songbook, and sends a request. Full version only. |
| App-store install | None. A pen is enough. No login and no charged phone. | The KaraFun comparison calls it a remote queue and phone request tools. It does not describe an app-store install on this site. | The PCDJ Karaoki comparison lists KaraoQuest as a free iOS app on the feature list. SongBookDB is a separate subscription from the host license. | None. Auto-KJ does not publish an app-store app. Singers use the browser. |
| Lineup the room can see | The sheet stays at the booth unless the host walks it over. A skip is closed by hand. | Not described on the Auto-KJ KaraFun page. | Not described on the Auto-KJ PCDJ page beyond the request reaching the host. | Place in line and an estimated wait, on the Full version. Singers can watch the same list. |
| Bad venue Wi-Fi | Paper needs no network. | The KaraFun page says to check network requirements for phone requests. Pro can sync the catalog for offline playback. | The PCDJ comparison does not describe SongBookDB on a failed venue network. | Full version LAN failover. Local requests continue. Song files stay on the booth computer. Cloud requests are not described with no network at all. |
| Price named on auto-kj.com | The printable sheet is free. The Free version that types those rows is $0. | About $49.99 a month for the catalog rental (US website, 2026, on the KaraFun comparison). | SongBookDB is $19 a month after a 30-day trial, or $15 a month paid annually. The Karaoki page instead says $19.95 a month and does not list the annual price. | Full version is $10 per month for one live show. Phone requests are not in the Free version. |
KaraFun Pro is a catalog rental. Auto-KJ plays the files you bring. Those are different jobs, which is the point of the KaraFun comparison. SongBookDB, on the PCDJ Karaoki comparison, is an extra phone-request subscription beside that Windows host app. Check those companies' own pages before you treat a price as current. The KaraFun page already says app-store prices can differ from the website.
What the Full version costs
The Full version is listed at $10 per month on the pricing section, for one live show at a time. A 60-day trial starts inside the app, with no card and nothing that bills automatically, one trial per account and per computer. Another live show at the same time is an extra $5 per month on the Full version. The Full version, paid once ($500), includes up to four shows at the same time and has no monthly bill.
The Free version remains $0 and does not include singer phones. Host downloads are for Windows, Mac, and Linux: karaoke software for Windows, Mac karaoke software, and karaoke software for Linux.
