| Integrations | The remixer page mentions a DAW integration in a testimonial, but does not name a supported DAW integration. | The documented workflow connects Separate, MIDI, Synth, Compose, Mix, and Export tabs so outputs can flow between pipelines; MIDI Out connects to hardware synths via the browser's Web MIDI API. |
| Privacy | Mubert says it does not sell personal information or use uploads, prompts, lyrics, or generated content to train third-party foundation models. | The project says audio stays on the user's computer and no internet connection is required after initial model downloads. |
| What it does | Mubert turns prompts, uploads, lyrics and unfinished ideas into generated tracks, vocals, remixes, stems and music videos. | StemForge is a local GPU-accelerated web workstation that separates stems, extracts MIDI, generates audio, composes songs, converts voices, mixes tracks, and exports files. |

The free plan provides 24 credits per month, with limits of 2 songs and 1 music generation monthly; free output is for personal, non-commercial use. Starter is $9.98 a month, with $14.90 also displayed, and includes 200 credits monthly, 40 songs, a commercial license, and unlimited downloads. Hobby costs $19.97 a month and Professional costs $33.30 a month. Paid outputs receive a commercial-use license subject to the terms. Users must own uploaded audio or have permission to process it.
StemForge
StemForge is a locally run, browser-based audio workstation for separating stems, extracting MIDI, generating audio, composing songs, mixing, and exporting. Demucs and BS-Roformer can separate audio into vocal, drum, bass, other, guitar, and piano stems; spectral analysis informs engine and model recommendations. For MIDI extraction, StemForge uses BasicPitch on instrument stems and faster-whisper with pitch tracking on vocal melodies. Its Synth tab generates text-conditioned audio with Stable Audio Open for up to 600 seconds, with optional audio or MIDI conditioning. Compose uses AceStep for song generation and RVC for voice conversion, with 14 built-in voices and a HuggingFace model browser. Mix combines stems, MIDI-rendered tracks, synth outputs, and composed songs; exports include WAV, FLAC, MP3, and OGG, individually or in a ZIP. The project says audio remains on the user's computer and no internet is needed after initial model downloads. Setup requires Python 3.12, FFmpeg, and FluidSynth with a GM soundfont. The software is free and open source.
