Undertow is a desktop app that guides you through your life story and outputs a complete multi-album AI music portfolio. Era by era, memory by memory, song by song — formatted for Suno, Udio, and whatever comes next.
How It Works
Set your musical identity — genres, BPM, guitar style, vocal delivery, atmosphere. This fingerprint flows into every song.
Define your life eras as albums. Each gets its own name, age range, emotional vibe, and musical identity. The sidebar IS your story.
Guided prompts cover 10 categories — people, places, secrets, turning points. Tag by emotional weight. The app helps you remember.
Group memories into song concepts. Find the title moment. Assign the emotional core. Map to song structure. Your life, framed as music.
Full craft layer: structure, metaphors, BPM, key, vocal arc, guitar direction, SFX. Build every song as a complete creative blueprint.
Platform-ready prompts for Suno, Udio, or both. Same song, correct format for each. Copy-paste. Generate. Your albums are ready.
Who It's For
Processing divorce, grief, becoming a parent, empty nest, milestone birthdays. Turn what you've been through into something beautiful.
You've lived a life worth documenting. Guided prompts help you surface memories you forgot you had — and shape them into albums.
Tired of one-off random Suno songs? Build cohesive multi-album bodies of work with real emotional arcs. Structure meets creativity.

Privacy
All your data — your eras, your memories, your song blueprints — lives in a single JSON file on your machine. No accounts. No cloud. No servers. Your life story never leaves your hard drive. Export when you want. Create when you're ready.
Your creative data uploaded to their cloud. Your memories stored on their servers. Your ideas become their training data. You don't know where it goes or who has access. Your life story shouldn't be someone else's product.
