Track Forge
Free Suno prompt builder. Pick the vibe, lay the structure, copy a clean prompt. No timestamp trap.
Pick a genre and a mood. Pick a tempo descriptor. Pick instruments and a vocal style. Then tap section chips in order to lay out the song structure: Intro, Verse, Chorus, Bridge, Outro. Track Forge emits a clean prompt with bracketed section tags and a natural style paragraph. Copy it, paste it into Suno.
Suno reads "at 20 seconds" as a length cap and clips the song short. Painful when you have a four-minute idea and Suno hands back twenty seconds. The fix is bracketed sections instead of timestamps. Track Forge enforces that by design.
- 01Pick one or two genres in the sidebar. Then a mood or two. The prompt preview updates live.
- 02Pick a tempo descriptor (slow ballad, mid-tempo, driving, etc). Pick instruments and a vocal style.
- 03In the Structure section, tap the section chips in song order: Intro, Verse, Chorus, Verse, Chorus, Bridge, Outro.
- 04Click Copy Prompt. The clipboard now has bracketed sections plus a natural-language style description, ready to paste into Suno.
- 05Save the recipe with Save Preset if you'll want it again. Every Copy auto-snapshots a Recent thumbnail you can restore from.
- Track Forge is an independent third-party tool. It builds the prompt string for you to paste into Suno yourself. Not affiliated with Suno, Inc.
- Section chips emit bracketed tags Suno parses well: [Intro], [Verse], [Chorus], etc. No seconds, no minutes, no length traps.
- Tempo is descriptive, not numeric. "Driving" and "slow ballad" land cleaner than "120 BPM" or "at 90 seconds".
- Nothing leaves your machine. Presets save to localStorage. Refreshing the page restores your last build.
Is Track Forge free, and is it affiliated with Suno?
Free. Independent third-party tool, not affiliated with Suno, Inc. It builds the prompt string for you to paste into Suno yourself.
Why does Suno cut my song to 20 seconds when I prompt 'at 20 seconds'?
Suno reads 'at N seconds' as a length cap, not a section marker. That's the timestamp trap. The fix is bracketed section tags ([Intro], [Verse], [Chorus]) instead of seconds-based instructions. Track Forge enforces bracketed structure by design — you can't even add a timestamp.
How do I write a better Suno prompt for full-length songs?
Pick a couple of genres, a mood, a tempo descriptor (descriptive like 'driving' or 'slow ballad', not numeric like '120 BPM'), instruments, and vocal style. Then lay out sections as chips in song order. Track Forge emits a clean style paragraph + bracketed structure that Suno parses well.
What section tags does it use?
[Intro], [Verse], [Chorus], [Bridge], [Outro], and a few variants. All bracketed because that's what Suno's parser expects. No timestamps, no minute markers, no length caps disguised as structure.
Why descriptive tempo instead of BPM?
Suno responds better to feel words than numbers. 'Driving' and 'slow ballad' land cleaner than '120 BPM' or '90 seconds in'. Same reason it ignores most numeric directions.
Can I save prompts I like for re-use?
Yes. Save Preset names a build and keeps it in localStorage. Every Copy Prompt also auto-snapshots a Recent thumbnail so you can restore from a casual session without naming it.
Does Track Forge generate the music itself?
No. It builds the prompt; Suno (or any other prompt-driven music tool) generates the audio. The point is Track Forge takes the friction out of writing a prompt Suno actually understands.
Where do my prompts go?
Nowhere. Presets save to your browser's localStorage. No account, no upload, no server.
