Brief

Hook

Tell me how you feel. I’ll find the music.

One-Liner

AI-powered mood-to-music matching — describe your vibe, get the perfect Spotify playlist.

Problem

You want to listen to music that matches your mood, but Spotify’s browse page is overwhelming. You scroll through “Chill Vibes,” “Focus Flow,” “Happy Hits” — none of them feel right. You just want to say “I’m tired but need to power through work” and get something perfect.

Who has this problem? Anyone who listens to music while working, relaxing, exercising, or just existing. That’s… everyone.

Solution

Vibe Check is a single-page app where you type how you’re feeling in plain English. AI interprets your mood and finds matching Spotify playlists instantly.

1. You type: “chill but focused, it’s raining outside”
2. AI extracts: low energy, instrumental, ambient vibes
3. App returns: 3-5 perfectly matched playlists
4. One click: opens directly in Spotify

No account needed. No setup. Just vibes.

Target User

Primary: Vibe coders, remote workers, students — people who live in headphones and want music that fits without the friction of searching.

Secondary: Anyone who’s ever said “I don’t know what I want to listen to.”
