The tool songwriters have been asking for is here.
Features unlike any other songwriting or audio production app.
SonoArc is the all-in-one studio for musicians and songwriters. Analyze live audio, capture pristine 16-bit takes, craft chords, lyrics and modes — and lean on The Wizard, a free AI mentor that runs locally, works offline, and never ships your voice to a cloud.

free AI mentor
One studio, everything in it
A toolbox that thinks with you
Deterministic theory tools you can trust instantly, a real recorder for real takes, and an AI mentor woven through it all — not bolted on.
Realtime analyzer
A 32k FFT analyzer watches your microphone live and locks onto key, mode, BPM and chords — no manual pitch-drop required.
Track Recorder
Capture uncompressed 16-bit WAV at your mic's native sample rate. Real recording, not a preview — clean takes you can actually use.
Chord, scale & Circle of Fifths
Instant music-theory lookup: build progressions, find borrowed chords, and navigate the Circle of Fifths with zero ambiguity.
Vocal Wizard
Find the range a voice actually lives in and the key that lands a chorus with power, not strain — producers use it to dial in an artist before the session even starts.
Rhyme Vault
Perfect and slant rhymes on demand, so a line keeps momentum across the bar line instead of waiting on a forced rhyme.
Mode Forge
Recast any progression into Dorian, Phrygian, Mixolydian and more — a fast way to reinvent a cover or catch an ear with one raised note.
The Wizard
A warm, slightly mischievous AI mentor who blends theory, song history and craft. Free to use, no per-message limits, on every plan.
Band projects
Shared sessions, members and an async version timeline so a whole band works the same song without stepping on each other's takes.
Real exports
Get your song out of the studio and into the world with MusicXML, MIDI and PDF export from every plan.
Video examples
See it in action
Short, real walkthroughs of the moments that matter — finding your key, recording a take, and recasting a whole section.
Why SonoArc is different
Private, powerful, honest
Four commitments that make SonoArc unlike any studio you've used.
Local-first privacy
Your projects, lyrics and recordings live in your browser's local database on your own device — never on our servers. We have no copy to lose or leak.
Free AI that stays home
The Wizard runs an AI model locally alongside the app — no third-party cloud, no token counters, no uploads. Unlimited and usable fully offline.
Deterministic when it should be
Chord Wizard, Rhyme Vault, Mode Forge and the Circle of Fifths are precise music-theory engines — instant and consistent, no black-box guessing.
Real recording, real export
Capture uncompressed 16-bit WAV and push your work into the world with MusicXML, MIDI and PDF. From idea to shareable demo in one session.
Reviews
Songwriters are already home
A 4.8 / 5 average across the studio's first 128 reviews.
“I spent ten years poking at DAWs that fight you. SonoArc found my key in seconds and the Vocal Wizard told me why the chorus was straining. My best song this year wrote itself in here.”
“The deterministic theory tools are a breath of fresh air — no guessing. The Wizard is a genuinely good weird advisor. It's like having a music professor with a very specific aesthetic on speed dial.”
“Our three-piece used to trade audio files over text and lose the plot every week. The async version timeline on Band means the song steadily gets better and nobody clobbers anyone's take.”

SonoArc DAW
Outgrown the app? Go pro.
The same SonoArc you already know, expanded into a full professional studio: a real multitrack timeline, a complete mixing console, and a plugin & instrument rack — built for people who want to finish the record here, not just start the song.
- Non-destructive multitrack recording and editing, unlimited tracks
- Full mixing console — per-channel EQ, sends, pan, and metering on every track
- Smack It! — one-click analog tape saturation on the master bus, no plugin shopping required
- A patch bay you actually label — visual, user-named routing instead of a hidden signal chain
- 192kHz / 32-bit float I/O with a 64-bit float summing engine
- Auto-detects your audio interface and configures the best supported sample rate
A separate purchase from the SonoArc app and its Single/Band plans — buy it directly on this website, no app store required.
Coming soon
Built to compete, not to copy
Pro Tools-grade editing and Studio One-grade workflow, then we add what they don't have — Smack It! and a patch bay built for humans, not engineers.
One purchase, no upsells
$99/yr gets the whole studio. No per-plugin paywalls, no separate mixer tier, no "upgrade to Ultimate" trap waiting six months in.
Made for the songs you already started
Every take, chord, and lyric from the SonoArc app carries straight into the DAW — you're finishing your song, not starting over in new software.
