Write a Song with AI for Free

Bring a lyric draft, story, mood, or scene. Wsong.ai turns it into two playable songs with melody, vocals, and instrumentation. The system supplies the first takes; you decide what belongs in the song.

Write a song

Three input paths

Choose the right starting point for your song

Start with the information you already know. An idea needs creative direction, finished lyrics need arrangement direction, and an instrumental needs a clear musical role. These examples show what to enter and what to check first.

Simple Mode

Write a song from an idea or scene

Describe the subject, emotional turn, musical character, and vocal perspective. Wsong.ai develops that brief into lyrics, melody, vocals, and instrumentation, so use this path when the concept matters more than exact wording.

Best when: You have a story, mood, title, theme, or visual scene but no fixed lyric draft.
Example input: “Cinematic indie-pop about leaving a hometown before sunrise; intimate female vocal, restrained verses, and an open final chorus.”
Check first: Does the hook express the central idea, and does the verse-to-chorus energy follow the story?

Write from an idea

Custom Mode

Turn your own lyrics into a song

Paste the lyric lines you want the vocal to follow, keep verse and chorus labels visible, and describe the sound separately. This path gives your wording priority while the model interprets phrasing, melody, voice, and arrangement.

Best when: Your verse, chorus, hook, or full lyric draft should remain recognizable in the result.
Example direction: “Warm acoustic soul, close male vocal, unhurried verses, fuller harmony in the chorus, and a short piano outro.”
Check first: Listen for pronunciation, crowded lines, section breaks, and whether the chorus receives enough contrast.

Use your lyrics Draft lyrics first

Instrumental

Create music without a lead vocal

Choose instrumental and describe the musical role, arc, palette, pace, and ending. Do not add lyric lines unless you want vocal content; the useful detail is how the track should function and develop.

Best when: You need background music, a score-like cue, a writing bed, or a track with no lead vocal.
Example input: “Nocturnal lo-fi instrumental for a quiet study scene; brushed drums, muted electric piano, soft bass, no lead vocal, and a resolved ending.”
Check first: Confirm there is no lead vocal, then compare structure, energy changes, instrument balance, and the ending.

How to write a song with AI in 3 steps

1
Describe what should stay recognizable
Name the lyric, scene, story, mood, or sound at the center of the song. A few concrete details give the model a clearer task than a list of broad adjectives.
2
Choose vocals, lyrics, and musical direction
Choose a vocal song or instrumental, then guide the genre, instruments, pace, energy, and voice. Use Custom Mode when exact lyric lines need to remain in the song.
3
Keep what works, then change one variable
Listen for the melody, phrasing, rhythm, or arrangement worth keeping. If neither take lands, revise one instruction instead of replacing the whole brief.

What one Wsong.ai generation includes

Before you start, know what a generation returns, how long a track can run, and which files paid plans unlock.

Two takes from one brief

Both results begin with the same prompt, lyrics, style, and model. The differences come from interpretation, giving you a concrete basis for the next edit.

AI song writer questions

What is an AI song writer?

An AI song writer is a tool for turning written musical intent into audio. With Wsong.ai, you supply the part that matters—the lyric, story, mood, scene, or instrumental role—and the system builds a first musical interpretation you can hear and judge.

Can I use Wsong.ai to turn lyrics into a song?

Yes. Paste your lyric draft into Custom Mode, keep the section labels visible, and describe the sound separately. Wsong.ai will sing those words with melody and accompaniment; you can then revise a lyric or change one musical instruction.

How many song versions does one generation create?

One generation creates two versions from the same lyrics, prompt, and style direction. Compare the melody, voice, pacing, and arrangement before choosing which result to continue.

Is Wsong.ai free?

Yes. The Free Plan starts after sign-in. Free songs are public by default and available for online listening. Downloads, private generations, and commercial usage rights depend on the paid plan and current license terms.

What can I do after I generate a song?

Keep the stronger version, revise one instruction and try again, or move into a focused tool. Wsong.ai can extend a section, make an authorized cover, remove vocals, split six stems, or convert a clear melodic part into a MIDI draft.

Can I download and use a Wsong.ai song commercially?

Paid plans include MP3 and WAV downloads, but downloads and commercial rights are different. Only eligible annual Starter and Plus generations receive the royalty-free commercial grant described in the License Agreement; Free and monthly-plan results do not.

Write your first song

Start with the detail that matters most. Wsong.ai gives you something concrete to react to; the final call stays yours.
