Short-Form Video Editor
Background music for a vertical clip
“A one-line mood was enough to get background music that matched the cut. I switched off the vocal and had two options to try under the edit.”
Listen to real songs, then start from their lyrics and style.
A live request usually takes 30–90 seconds. Playback and download start when the audio files are ready.
Start from a one-line idea or your own lyrics. Two complete songs come back in about a minute or two.
In Simple mode, describe the genre, mood, and instruments in one sentence. In Custom mode, add a title, your lyrics, the styles you want, and any styles to avoid.
Pick an automatic, female, or male lead vocal, or switch to Instrumental for music without singing. The current cost is shown before you click Generate.
Each run returns two different songs with a title, cover art, and lyrics. Play both, keep the one you like, and download it as an audio file.
Create
Turn a short brief or a finished lyric into songs for gifts, videos, brand cues, and songwriting demos.
Name the genre, mood, and instruments. The AI writes the lyrics, melody, and arrangement for you.
Paste lyrics with [Verse], [Chorus], and [Bridge] tags, set the style, and hear how your words sound as a song.
Switch off the vocal to create background music for videos, podcasts, ads, and presentations.
Every generation returns two different songs from the same brief, so you can pick the stronger one.
What it is
An AI song generator creates a complete song from a written description or from lyrics you provide. It returns finished audio with vocals, melody, arrangement, and mix, rather than a loop you still need to build into a track.
On GPTProto, the generator runs Suno's Chirp v6 music model. In Simple mode you describe the song in a sentence and the model writes the lyrics and the music. In Custom mode you control the title, the lyrics, the styles, and the styles to avoid.
Every run returns two different songs from the same request. Each one comes with its own title, cover art, and lyrics, so you can listen to both and keep the better take.
Better results
A specific brief gives the model a clearer target than a vague one.
Name the genre and the mood: “Warm indie pop about late summer, acoustic guitar and soft drums” is easier to follow than “a nice song”.
Describe sounds, not artists: Prompts that name a real recording artist are rejected. Describe the genre, tempo, instruments, and vocal tone instead.
Mark the song sections: In Custom mode, tags such as [Verse], [Chorus], and [Bridge] show where each part of your lyrics belongs and which lines repeat.
Keep the style list short: A genre, a feel, and two or three instruments are usually enough. Use Exclude styles for sounds you do not want.
Choose the vocal on purpose: Pick a female or male lead when it matters to the song, or choose Instrumental for background music.
Compare both songs: The two results can differ in melody, structure, and length. Listen to both before deciding to change your brief.
Choose a mode
Both modes create complete songs. They differ in how much of the song you write yourself.
| Dimension | Simple Mode | Custom Mode |
|---|---|---|
| What you provide | One description of up to 500 characters | A title, lyrics of up to 3,000 characters, styles, and styles to avoid |
| Who writes the lyrics | The AI | You, or a starter template you edit |
| Control over structure | The AI decides verses and choruses | You place [Verse], [Chorus], and [Bridge] tags |
| Best for | Quick ideas, moods, and background music | Finished lyrics, gifts with names, brand jingles, and songwriting demos |
Start with Simple mode to explore a sound. Switch to Custom mode when the words matter.
Before you publish
A generated song still carries rights and disclosure responsibilities.
Use lyrics you have the right to use: Write your own words or use lyrics you have permission to adapt. Do not paste protected lyrics from another song.
Do not imitate real artists: Describe a sound instead of asking for a specific singer or band.
Check the terms before commercial use: Review GPTProto's terms and the model provider's terms before releasing a song commercially.
Label synthetic vocals when appropriate: Do not present an AI vocal as a performance by a real person, and follow the disclosure rules of the platform where you publish.
From birthday songs to background music, creators use the AI Song Generator to hear an idea as a finished song without booking a studio.
