Your chorus app, paid once.
Part tracks, the score, rehearsals, members and dues in one app your chorus owns. One payment for the whole chorus. No yearly bill, no fee per singer.
The first 25 choruses get the install done for them, at no extra cost. Full refund any time before your install.
Learn your part between rehearsals
Part tracks with a mixer
Turn your part up, the others down. Slow it down, change the key, loop the bars you keep missing.
The score follows along
The sheet music scrolls with the track, so nobody hunts for bar 44.
Record a take for the director
Sing it at home, send it when it is ready. Takes stay private until the singer sends them.
Your moves, your cues
Choreography placed on the bars, with who does what: everyone, a part, or named singers.
Tuner and pitch pipe
The live note and how many cents sharp or flat, plus starting notes in the key you actually sing.
Run the chorus from one place
Members and parts
Who sings what, invite links, roles for the music team.
Rehearsals and attendance
Calendar, weekly rehearsals, attendance, set lists for each performance.
Announcements and dues
News to the whole chorus or one section. Dues tracked as paid, unpaid or waived.
Your chorus, your colours
Your logo and colours on every singer’s phone. English and French.
PDF to Tracks
Turns a PDF chart into one learning track per part, on your own Windows PC. Needs your own ACE Studio licence.
An assistant in Admin
Drafts announcements and answers questions. You paste your own key from Claude, OpenRouter or OpenAI, so it bills you directly.
Connect Partwise to Claude
Ask Claude about rehearsals, attendance and repertoire, straight from your chorus data.
You reserve. I install. Your singers sing.
Reserve your spot
$349 once, by card. You get a welcome email with a few questions about your chorus.
Pick an install date
Founding installs start in mid-November 2026, in the order choruses reserved.
I set it up for you
Partwise goes into your chorus’s own free accounts. Your data stays yours, not in a shared app.
Invite your singers
One link. It opens in any phone browser and can sit on the home screen like an app.
Once. Then nothing.
- Every singer, every part, no member cap
- Install done for you (first 25 choruses)
- Every update, including Connect to Claude
- English and Canadian French
- Full refund any time before your install, and for 30 days after it
After the install
Partwise runs on free plans from Supabase and Cloudflare, opened in your chorus’s name. For most choruses that means $0 a month.
Honest limits: the free database holds about 1 GB of files; a chorus with a big track library may outgrow it and pay Supabase $25 a month. A free database also goes to sleep after a quiet week (one click wakes it). The assistant is optional and bills your own AI account; light use runs about $1 to $5 a month. Your costs depend on your chorus.
25 choruses shape what comes next
Founding choruses get the install done for them, a direct line to me while it beds in, and a real say in what gets built next. After 25, the install becomes a paid add-on.
Denis Laflamme, Claude Academy
Do singers have to install anything?
No. Partwise opens in the phone’s browser. Singers can add it to the home screen so it opens like an app.
Who owns our data?
Your chorus does. Members, tracks and recordings live in your chorus’s own Supabase account, not in a database shared with other choruses.
What if Claude Academy disappears?
Partwise keeps running. It lives in your accounts, not mine.
We already have learning tracks from a producer.
Good. Upload them per part and they play in the mixer with the score. Partwise does not replace your arranger or your track producer.
Is it in French?
Yes. Every screen is in English and Canadian French, and each singer picks their own language.
Can we pay by invoice or cheque?
Write to me and we will sort it out.
Reserve your chorus’s spot.
$349 once. Install included for the first 25. Refund any time before your install.
