## 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

## Output

Output is a music technology brand rather than a single app. Founded by musicians and producers, the company builds a catalog of virtual instruments and effect plugins designed to fit straight into major DAWs such as Ableton Live, Logic Pro, FL Studio, Pro Tools and Cubase. Its range covers everything from cinematic textures and granular engines to practical mixing and creative distortion tools.

Alongside software, Output publishes expansion packs and sample content that extend its instruments, so the catalog grows over time rather than being a fixed set of products. Titles such as Arcade, Portal, Thermal, Exhale, Substance and Rev are aimed at different jobs — melody and loop creation, generative texture processing, heavy creative effects, and vocal or bass design. Licensing is handled per product, with perpetual licenses for individual plugins and subscriptions for content-driven products, and the store frequently runs sales that discount large portions of the catalog.

The site is primarily a product store and resource hub: each plugin has demo audio, walkthrough videos, system requirements and compatibility notes, and there is an education/student offering as well as bundles. Because pricing varies by product and by current promotion, buyers should check the live store page for accurate figures.

**Pricing & Plans:** Freemium and paid mix: individual plugins are sold as perpetual licenses and content products like Arcade run on subscription, with frequent store-wide sales, bundles and educational discounts. Exact prices change with promotions, so the live store page is the source of truth.

- **Creative effect plugins:** Tools such as Portal and Thermal deliver granular, textural and distortion-based effects for shaping sound in unusual directions.
- **Virtual instruments:** Sample-based and synthesis-driven instruments cover bass, vocals, pads, keys and cinematic textures.
- **Loop and sample content:** Expansion packs and sound libraries extend the instruments with new material for songwriting and scoring.
- **DAW integration:** Plugins run as VST, AU and AAX formats so they slot into the major production environments.
- **Bundles and educational pricing:** Product bundles and student or education offers make larger parts of the catalog accessible at a lower cost.

**Strengths:** Broad catalog covering instruments, effects and sample content; Plugins work across the main DAWs via VST, AU and AAX; Strong reputation for creative and cinematic sound design tools; Frequent sales and bundles reduce the cost of building a toolkit

**Limitations:** Catalog is split across many separate products, which can add up in cost; Some products rely on a subscription rather than a one-time purchase
