A complete neon music studio AND a private AI that works 100% offline — no setup, no account, no internet, ever.
Make beats on an 8-pad sequencer, play a polyphonic synth, then chat with an on-device AI that ships ready to go the instant you open the app. While other private-AI apps make you download a model first, Neon Synthetics already has one built in. Press play. That's it.
— THE MUSIC STUDIO —
• 8-Pad Beat Sequencer: tap out drums fast on a classic step grid with genre presets.
• Polyphonic Synth: play lead, bass, pluck, pad, organ and bells with rich, warm 80s tone.
• Key + Scale Snap-Lock: lock to any key and scale so every note you play stays in tune.
• BPM, Tap Tempo & Metronome: nail your timing every time.
• Ask the AI for a Beat: tell the on-device AI a vibe and it builds you a starting pattern.
Go further with NEON PRO (one-time unlock):
• Sample Vault: record, import and chop your own sounds.
• Voice & Lyric Lab: capture vocals and write to your track.
• Mixer & FX: balance levels, add color, shape your mix.
• Song Mode + Pattern Library: arrange full tracks and save your patterns.
• Audio Export: bounce your music out to share anywhere.
• Music Visualizer: watch your sound come alive in neon.
Sound School: built-in music-theory lessons, so you actually learn while you make.
— THE PRIVATE AI —
• On-Device AI Chat: a real language model that runs entirely on your iPhone.
• Offline Wikipedia: ask anything and the AI cites a built-in encyclopedia — no signal needed.
• Notes & Lists: capture ideas, lyrics and to-dos.
• Voice Recorder: record memos, riffs and reminders.
Because it all runs locally, it works on a plane, in the subway, off-grid — anywhere.
— FREE vs NEON PRO —
Free forever: AI chat, offline Wikipedia, notes, lists, voice recorder, the 8-pad sequencer, the synth, BPM/tap/metronome, genre presets and "Ask the AI for a beat."
NEON PRO — one-time $2.99, no subscription, ever: sample vault, voice & lyric lab, mixer & FX, song mode, pattern library, audio export and the music visualizer. Pay once, own it.
— YOUR PRIVACY IS ABSOLUTE —
No account. No sign-up. No internet connection required for anything. Your chats, your music, your notes and your voice never leave your device — there's nowhere for them to go. Nothing is uploaded, nothing is tracked, nothing is sold.
Neon Synthetics. A music studio and a private AI, glowing in synthwave neon — fully yours, fully offline.
