A listening singing coach · NotSoSure
Antara
find the inner voice.
Singing is taught one-to-one in a gurukul, or not at all. Antara is a mic-first coach that listens in real time, names exactly what your voice did, and turns the long, lonely arc of practice into a wall of earned medallions.
Not a karaoke score. Not a leaderboard. Not a single emoji. A patient, specific, reverent ear: the gurukul, rebuilt as a museum you can sing in.
India-first and global from day one. Hindustani, Carnatic and Western voice sit as first-class equals, with no “world music” sub-menu and no condescension. Just a coach that knows the difference between Sa and a karaoke percentage.
First, it learns your Sa.
Six unhurried screens. You sing a comfortable “Saaa” for five seconds; autocorrelation reads the waveform and finds the true centre of your voice. That note becomes home, and every drone and exercise after it shifts into your key.
Find a quiet room
No headphones, no backing track. Just you and the mic.
Breathe low
One slow breath from the belly, the way a session should begin.
Sing a comfortable Saaa
Hold it for five seconds at the pitch that feels like home.
Autocorrelation listens
Antara reads the waveform and finds the true centre of your tone.
Your tonic locks
That note becomes your Sa, calibrated to your own voice.
Every exercise shifts
From here on, the drone and the sargam live in your key, not someone else's.
Five ways it listens
Every mode is mic-first and reverent. It names what your voice did, then gives one specific next step: the gurukul’s patience, made of code.
A coach that hears the note, not the score
“you're 30¢ flat on Sa, brighten the vowel”
Antara streams your voice over Web Audio in real time and names exactly what it did, in plain, body-grounded language. No karaoke percentage. A specific next step, spoken back to you, the moment you sing it.
- Live mic, WebSocket streaming
- Body-grounded reactions, on-device TTS
- 12-word cap · one exclamation a session
Sargam, across five ragas, in just intonation
“Sa Re Ga Ma Pa Dha Ni”
A scrolling lyric line over a tonic drone, with just-intonation targets, not equal-tempered approximations. Bhairav, Bilawal, Kafi, Yaman, Bhupali, each with its own gravity, each a first-class path beside Western voice.
- 32 exercises across 5 tracks
- Just-intonation pitch targets
- Indian classical and Western, as equals
A tanpura that breathes from your own Sa
“twelve tonics, four voicings, one centre”
A pure Web-Audio jawari approximation: the resonant shimmer of a real tanpura, calibrated to the tonic you set in onboarding. Every exercise shifts into your key, so the drone is never someone else's home note.
- 12 tonics · 4 voicings
- Jawari resonance, synthesised
- Tuned to your personal Sa
The whole practice room, in instrument modes
“guitar, tabla, harmonium”
Beyond the voice: a guitar tuner across five tunings including DADGAD and drop D, ten tabla bols to keep time, and a harmonium tuner with a five-raga pakad library. The gurukul, not the gym.
- 5 guitar tunings · 10 tabla bols
- Harmonium tuner + 5-raga pakad
- One reverent, anti-Smule room
Nineteen models, listening on one backbone
“record four seconds · watch them all fire”
The Model Lab lets you record or upload audio and watch every trained model react in parallel, confidence bars rising together. Nineteen task models on a single shared speech encoder: the ear behind the coach, made visible.
- 19 task models, one speech encoder
- Record 4s or upload audio
- Parallel inference, confidence bars
It speaks like a guru, not a slot machine.
Twelve words at most, so the note stays louder than the talk. One exclamation is the whole session’s budget. No confetti, no fire, no clapping hands. You pick a Carnatic or a Western register, and it stays in that world with you.
This wall fills
as you sing.
Thirty collectible medallions, earned through milestones, not bought. First Note. Seven Sessions. Century. Three Paths. A long, lonely practice, made visible and kept.






























Earned, never bought.
On the wall, each medallion turns to read its unlock story: what you did to earn it, and why it is bronze, silver or gold. A few of the thirty, turned over here.

the very first sung note Antara hears
Before technique, before a single correction: you opened your mouth and a tone came out. Bronze, because everyone starts here, and almost no one keeps going.

seven days of returning to the mic
Not a streak you can buy back. Seven separate times you sat down, set your Sa, and practised. The habit, not the highlight.

one hundred logged practice sessions
A hundred quiet evenings. No audience, no leaderboard, no applause. The medallion is the only witness, and that is the point.

practising Hindustani, Carnatic and Western voice
You crossed every register Antara teaches and treated each as an equal. Gold, because few singers ever leave the one room they were taught in.
4 of 30 shown · 4 bronze, 19 silver, 7 gold in all
Built deep, counted honestly
collectible medallions: 4 Bronze, 19 Silver, 7 Gold, earned across the long arc of practice.
Your practice becomes presence.
No infinite deck of duets. No scoreboard. Just your voice, a listening ear, and a wall that fills, one earned medallion at a time.
