Editing from your computer
Typing lyrics with your thumbs is a punishment. So Eutepio does the opposite direction too: the phone starts a small server, and a computer on the same Wi-Fi gets a full editor for your library in its browser.
There is no cloud and no account in this. The data stays on the phone; the computer only borrows it over the local network.
What it is for
- Typing up five songs from paper in one evening, on a real keyboard.
- Building a setlist on a big screen where you can see the whole thing at once.
- Printing a song or a whole setlist.
- Pulling in a song from a URL, or from a file sitting on your computer.
Turning it on
- On the phone, open the Connect tab → Editing from your computer and switch it on.
- The phone shows a QR code and an address like
http://192.168.0.42:8770/?k=…. - Scan the QR code from the computer, or type the address into the browser by hand.
- Confirm that computer on the phone. For every new computer the phone speaks up, shows its address and offers Allow, Deny or Turn editing off. Until then the page says "Confirm the connection on your phone".
The address can differ from one session to the next. Always use the one the phone is showing right now.
After 30 minutes of inactivity editing turns itself off. You do not have to think
about it when you close the laptop and walk away.
While it runs, the phone keeps its screen and Wi-Fi awake using the same service a band session uses. If sync is running at the same time, both features share that service, so your battery does not pay twice.
What the page can do
The page is a single file with no external dependencies — it loads nothing from the internet, because the phone serving it may not have any.
| Area | What you get |
|---|---|
| Library | Song list, search, filter by tag |
| Editor | ChordPro syntax highlighting, live preview beside the text, find and replace |
| Chords | Chord suggestions for the song's key, transposition |
| Setlists | Create, rename, reorder songs, event date and venue, start time, breaks |
| Attachments | PDFs, MusicXML and photos — not just viewing, but uploading, rotating, reordering and deleting |
| Notation | Switch between ChordPro and chords above the text; since 0.4.2 back again without changing the song |
| Import | From a URL, or from a file on disk (up to 4 MB) |
| Export | Save one song as ChordPro |
| Printing | Ctrl+P |
A song you are in the middle of survives F5 — the draft stays in the page, so closing the tab by accident does not cost you the work.
Changes reach the phone immediately. It works the other way too: edit something on the phone and the page notices on its own, with no refresh.
Printing
Ctrl+P prints whatever you have open. The page carries its own print layout, so what comes out of the printer is the clean song text, not the editor interface.
Security
ℹ
The server runs on your local network only. It has no public address, goes through no relay, and cannot be reached from the internet.
Two things guard access.
A six-character key. It is in the QR code and in the address, and the browser sends
it with every request. Without it the server does not answer. The key persists between
launches — neither switching off nor restarting invalidates it, only the New key
button.
Confirming the computer. The key alone is not enough: every new computer has to be
let in from the phone. Switching editing off revokes the computers you allowed, so
it asks again next time. The key itself stays valid.
What that means in practice:
- On home or rehearsal-room Wi-Fi you are fine.
- Be careful on public Wi-Fi in a club or a hotel: you are on a shared network and the connection is not encrypted. Unlike a band session, it cannot be locked with a password. Neither the key nor the confirmation helps against somebody listening to that network — they will see what you send. Better not to turn this on there.
- If the key has leaked, press New key. Switching off is not enough.
What actually travels over the network is detailed in the Privacy Policy.
Limits
- It is a library editor, not the stage. Auto-scroll, the metronome, annotations and backing tracks are not driven from here.
- The phone and the computer must be on the same network. Mobile data is not enough — the phone would have an address the computer cannot reach.
- File import is capped at 4 MB.
- If the phone puts the screen fully to sleep or switches to another Wi-Fi, the connection drops. The page will not reconnect on its own — refresh it.
When the page will not load
| Symptom | What to do |
|---|---|
| The browser says it cannot connect | Check that the phone and the computer are on the same Wi-Fi. A phone on mobile data will not do |
| The page asks for a key | The ?k=… in the address is missing or wrong. The phone shows the key below the address — type it in, or scan the QR code again |
| The page says "Confirm the connection on your phone" | Pick up the phone and tap Allow. It asks once per new computer |
The QR code shows a 10.x or 172.x address | That is fine — the app picks the address that matches how your network is built |
| It works for a while and then drops | The phone most likely put the network to sleep. Keep it on a charger with the screen on while you work |
| Last time's address does not work | It may have changed. Use the one the phone shows now, or scan the QR code |
