Every tool runs on a pool of free credits that refills daily. No seat licences, no subscription — pay only for the tasks you run.
Active tools
8
Check status first, then decide whether to launch.
Task groups
3
Filter by goal first, then compare I/O and runtime.
Zero-credit entries
1
Already have MIDI? Zero-credit tools are the cheapest path.
GPU workflows
7
Complex separation / transcription typically needs GPU.
Tool workbench
This isn't a marketing showcase — it's the pre-launch decision panel. Each card tells you the scenario it fits, what it produces, how long it takes, and how many credits it costs.
1. Pick a task group first: separation, vocals, MIDI conversion. Don't blind-search across every tool.
2. Check input and output: confirm you're uploading audio vs MIDI, and what you'll get back.
3. Check credits and runtime: for heavy jobs, run a sample first before submitting in bulk.
Task group
Split vocals, accompaniment, or stems first, then move on to practice, mixing, sampling, or further analysis.
Decide first whether you want vocals, accompaniment, or finer multi-stem output.
Separated vocal and accompaniment stems, ready for practice, sampling, or downstream processing
Finer multi-stem output for handling drums, bass, harmony, and more individually
Task group
Convert full audio or single-instrument clips to MIDI — ideal for transcription, teaching, arranging, and quick drafts.
Use multi-instrument transcription for full songs, a piano-specialist model for solo piano, and the zero-credit converter for existing MIDI files.
A multi-instrument transcription draft, ready for further editing, arranging, or harmonic analysis
A lightweight piano MIDI result, good for a quick check of melody and rhythm
A quality-first piano MIDI result, suitable for detailed score editing
Piano MIDI with sustain/soft pedal events for more faithful playback
MIDI output in a different encoding or compatibility format — no recognition or inference involved
Task group
Handle vocals, timbre conversion, and cover workflows — well suited for demos, test takes, and character-voice experiments.
This group cares most about vocal quality and clean source material; confirm the lead vocal is clear before uploading.
How it works
Run real models with free credits. Tasks run on the server; download outputs when done.
STEP 01
New accounts get free credits — no card required. Pick a tool and run a representative sample first.
STEP 02
Submitted tasks join a queue. Credits are billed by GPU time; failed tasks are refunded automatically.
STEP 03
When complete, download stems, MIDI, or converted output directly. No subscription, pay only for what you use.
