Stem Splitter is an AI audio tool that processes or generates sound — separating stems, cleaning up recordings, or producing new audio — using open-source audio models. It runs free on Free.ai with no sign-up required to get started.
Stem Splitter is built for musicians, podcasters, and editors who need studio-style results without studio software. It covers vocal removal, mastering, format conversion, and other audio production tasks — pick this tool when that’s what you need.
Provide the source — paste it, upload it, or link it — and Stem Splitter converts it to the target format, ready to download.
Yes. You get 2,500 free tokens per day with no account at all, or 30,000 tokens/day with a free account. Stem Splitter draws from that daily pool; if you need more, token packs start at $1.
Stem Splitter delivers audio as WAV by default, which you can convert to MP3 or other formats with any audio tool. Sample rate and channel layout are preserved from the source where applicable.
Feed Stem Splitter the cleanest source you have — less background noise in means better separation and clarity out. For multi-step work, process one stage at a time and listen before continuing.
Yes. Audio you produce with Stem Splitter is yours to use in videos, podcasts, and other commercial work. The underlying audio models are open-source with permissive licenses.
No. Use Stem Splitter immediately as a guest. A free account doubles your daily tokens to 30,000, saves your history, and unlocks larger inputs — but it is optional.
Audio you send to Stem Splitter is processed on our servers and is not used for model training. Files are not retained beyond the share window unless you save them while signed in.
Stem Splitter runs on best-in-class open-source AI models on our own infrastructure — no third-party API keys, no per-call surcharge. We update the underlying models as better ones are released.
Yes. Stem Splitter works in any modern mobile browser — the layout adapts to your screen, so you can use it on a phone or tablet with no app to install.
A lot. Beyond Stem Splitter, Free.ai bundles vocal removal, mastering, format conversion, and other audio production tasks alongside hundreds of other free AI tools — chat, images, audio, video, code, and more — all sharing the same daily token pool. Browse the categories to find your next one.
