## Harmonai

Harmonai describes itself as "a Stability AI Lab releasing open-source generative audio tools to make music production more accessible and fun for everyone." The project's stated mission is to hand creative control back to artists: instead of locking generative music behind closed services, Harmonai publishes its models and code so that producers, sound designers and developers can run them locally, remix them, or build entirely new instruments on top.

The lab is best known for generative audio work in the dance and electronic music space, including models that generate original loops, textures and sample material from text or audio prompts. Its output is aimed at the practical side of making music: filling out a track with sounds that fit a genre, generating "infinite" custom sample libraries, or exploring unexpected timbres during sound-design sessions.

Because everything is open source, Harmonai is as much a community as a product. Musicians and ML engineers gather in its Discord to share generations, report issues and collaborate on new models, while the GitHub organization hosts the model code and weights. There is no paid tier — involvement means joining the community, testing tools and contributing back.

**Pricing & Plans:** Harmonai is free and open source. The project releases its generative audio models and code publicly at no cost; there are no subscription tiers or paid plans, and the main cost of use is your own compute if you run the models locally.

- **Open-source generative audio models:** Downloadable model code and weights for generating music, loops and sound textures, released publicly so anyone can run, inspect or fine-tune them.
- **Custom infinite sound libraries:** Generate original sample material on demand instead of hunting through fixed packs, building a personal library of sounds tailored to your genre.
- **Practical music-production focus:** Tools are designed by and for musicians, targeting real workflows such as beat-making, sound design and electronic production rather than novelty demos.
- **Community and collaboration:** An active Discord and GitHub organization where producers and researchers share results, file issues and co-develop new audio models together.
- **Backed by the Stability AI ecosystem:** Developed as a Stability AI lab, giving the project access to research infrastructure while keeping its audio tools openly licensed.

**Strengths:** Completely free and openly licensed, with no subscription or credit system; Models and code can be run locally, giving full control over your audio and workflow; Focused on real music production rather than gimmicky one-off demos; Active community on Discord and GitHub for support and collaboration

**Limitations:** No polished end-user app or web editor — you may need technical setup to run models; Documentation and tooling assume some familiarity with Python and ML environments; Local generation requires a capable GPU, so results depend on your own hardware

## Moises

Moises began as one of the best-known AI vocal removers and has grown into a complete creative suite for musicians. Its core stem separation engine isolates vocals, drums, bass, guitar, piano, keys, winds and strings, supporting up to 27 stem types with high-fidelity models. You can mute or solo any part, drop the tempo, transpose the key and loop tricky passages to practice them slowly.

Beyond practice, Moises adds composition and performance tools. A chord finder detects the harmony of a track, lyric transcription writes out the words, and a built-in metronome and speed changer help you stay in time. Moises Studio lets bands, producers and co-writers arrange, record and edit the same session together in the browser in real time, with no file handoffs. Video recording tools capture performances with studio-quality audio.

Moises runs as a web app in any browser and as native apps for iPhone, iPad, Android, macOS and Windows, so you can practise on the bus or produce at your desk. It is trusted by Grammy-winning artists, music schools and millions of hobbyists alike, and the company states it never trains on your personal audio.

**Pricing & Plans:** Freemium. The free tier includes a limited number of uploads per month and a subset of features. Paid subscriptions unlock unlimited uploads, higher-quality separation models, longer tracks and advanced tools. Check the official pricing page for current tiers.

- **AI stem separation:** Split any track into up to 27 isolated stems including vocals, drums, bass, guitar, piano, keys, winds and strings.
- **Practice controls:** Slow the speed without changing pitch, transpose the key, loop sections and mute or solo your part while you play along.
- **Chord detection and lyrics:** Automatically detect the chords in a song and transcribe lyrics so you can learn songs faster.
- **Moises Studio collaboration:** Arrange, record and edit the same session with bandmates or producers in real time, right in the browser.
- **Audio mastering:** Polish your own recordings with AI-assisted mastering to get a louder, more balanced finished track.

**Strengths:** Excellent separation quality across many instrument types; Available on web, mobile and desktop so practice fits any setting; Chord finder, lyrics, tempo and key tools cover the whole practice loop; Free tier is genuinely usable for casual learners

**Limitations:** Free tier is limited by monthly uploads and feature access; High-quality models and unlimited uploads require a paid subscription; Separation artifacts can still appear on dense or low-quality mixes
