First & only · AI scores the chanting

Know every word before you walk up.

Your child hears the cantor, chants it back, and sees exactly what to fix — every word scored the instant they sing it.

The real challenge

The hard part isn't the day — it's the months before it.

$1,000–3,000
A private tutor
6–18 months
Of weekly lessons

Months of preparation come down to a few minutes on the bima. A tutor takes time and money — and even then, nerves can undo it. The lesson was never the hard part. It's the daily practice in between — alone, with no one to catch the word that slipped.

How it works

Practice that tells them exactly how they're doing.

1

Hear it.

Listen to a cantor chant your exact verse, words highlighting as they're sung.

2

Chant it back.

Record right in the app — private, judgment-free, as many times as it takes.

3

Watch it light up.

Instant, word-by-word feedback on melody (trope) and Hebrew — green for what they nailed, flagged for what to drill.

Every other app records it and sends it off for a person to grade by hand — so you wait. RoboRebbe's AI scores it the second they sing it.
Why it works

Built on how chanting actually sticks.

Two things make a skill stick: daily repetition and instant, specific feedback. RoboRebbe runs both — every day.

Chant it back, out loud

Recalling the verse from memory sticks deeper than reading it or hearing it again — and the trope's steady tune makes it stickier still.

A little, every day

Short daily reps, spaced out — the study method research rates highest across hundreds of studies.

Instant, honest feedback

Every word scored on melody and Hebrew, calibrated to expert judges — so "you nailed it" means they did.

Your cantor still gives the final sign-off. RoboRebbe just makes sure the reps in between are done right.

Works with your cantor

The daily practice between lessons.

RoboRebbe doesn't replace your cantor or tutor — it frees their time to perfect, not correct. Every word that needs work becomes a one-tap drill: hear it slowed down, repeat, lock it in.

Tap בראשית: הָאָרֶץ — hear it slowed down
Repeat until it locks in
Then your cantor gives the final sign-off.
Built so they actually practice

Practice that doesn't feel like practice.

At the Bar Mitzvah, the congregation showers them with soft candy the moment they finish. In the app, every verse they master earns another — so the daily work quietly builds toward the real throw.

Questions

The honest answers.

It happens to everyone, and it's smaller than it feels — every synagogue has a gabbai right there to quietly give the word, and the service flows right on. What builds the calm to walk up is daily practice that catches the words that slip, so there's nothing left to trip on. That's exactly what RoboRebbe drills between lessons. Read the honest answer →
Yes — all 54 portions and every haftarah are in the app, taught verse by verse. Pick yours and practice it as often as you need.
RoboRebbe teaches one trope melody. The best way to check the fit is to hear your first verse free before you subscribe — so you know it works for your family before you pay. (More melodies are on the roadmap.)
Its AI scores every word on melody and Hebrew, calibrated against expert human judges, and it comes from the team behind Wizer.me (10M+ learners). Think of it as a tireless practice partner between lessons — your cantor still gives the final sign-off.
RoboRebbe teaches traditional cantillation and is a practice coach, not a religious authority. It's built to work with your clergy, not around them.
That's what the candies, streaks, ranks, and weekly leagues are for — short daily sessions that feel like leveling up, not studying.

The countdown breaks the portion into daily verses paced to your real date, so it adapts to whatever runway you have. The honest answer: start today.
The core loop is hear-it-then-chant-it-back, so a student can start without fluent reading. Verses are bite-sized, self-paced, and private — master one phrase before moving on.
