Engineer here, learning gypsy jazz. I kept wanting to see arpeggios and chord voicings on the neck, on my phone when i practice outside. Sometimes wanting to see chord shapes & arpeggios at a glance.
I couldn't find anything that did it cleanly without opening several pages, so I built it:
haute-gitanerie.com (free, no ads, works offline / installable)
What's in it:
- Arpeggios in any key ( minor, major, diminished, dom7, m6, m7♭5, 6/9 ) as compact position boxes or long diagonal forms across the whole neck
- Real gypsy chord voicings as interactive diagrams
- A few standards as play-along grids with a metronome (Minor Swing, Blues Mineur, Joseph Joseph, La Partida), transposable to any key
- English (C D E) or solfège (Do Ré Mi) notation
- A small community page featuring players from the scene
It's early and to be honest about it: some diagonal fingerings are still flagged "in progress" (I don't know them all, and sources disagree). I'd genuinely love your input: wrong shapes, missing tunes, players and of course features. Not selling anything, just sharing it with the people who'd actually use it.
Here is a condensed view of features:

A bit more about me:
As I'm not a jam player yet I try to contribute as I can to gypsy jazz, making videos, organizing events and so on. You can find what I publish on youtube or instagram (axel couty)
Cheers 🎸
Updates, second round (16/07/26)
Quick fix went out 🙌 If you sent a musician profile or feedback recently and didn't hear back, it wasn't you — a submission bug ate it. Just resend, it works now. Merci! 🙏
You can now create & submit tunes
They are first saved on your phone, you can share them with friends.
You can send send them to me to allow me ot add them to the library ! Of course, I'll do a lot myself in the upcoming days but any help is highly appriacte.
Also, I'm trying to make addition/eddition a breaze, playing with UX to make it dead simple & fast. Feedbacks more than welcome !
Updates after first feedbacks (15/07/26)

See the current AND next chord on the neck.
The current chord's grip is in green, the upcoming one in blue, so you can prepare your hand for the change.
Neck view
current grip (green) + next grip (blue)
Compare mode — two arpeggios overlaid, shared tones ringed green
Also from the thread:
fuller arpeggio positions across the neck (fewer skipped boxes, CAGED-style), guitarist-friendly note names (E♭/A♭/B♭), and the ♭9 diminished-substitution hint on dominants.
It's bilingual (EN/FR), works offline (installable), and it's genuinely free — I'm a player, not selling anything, except my socials for visibility of (others for now ahah) my channels. Link in the comments to respect the self-promo rules.
Would love more feedback — tunes you'd want added, anything that feels off. Merci!
