HarmonAI
Pros
- + Genuinely free and permissively licensed — all three repositories are MIT, so commercial use of Dance Diffusion tooling costs nothing and carries no usage caps.
- + sample-generator's Colab notebooks made training a generative audio model on your own samples accessible without a local ML setup — 1,116 stars and 168 forks reflect real community use.
- + The Stable Audio lineage it started is alive and open: Stable Audio 3 under Stability AI (MIT, Hugging Face checkpoints, 433M-param small-music model, 120-second max length) is the maintained continuation.
- + The lab published early and substantively — Stable Audio's documented benchmark (95 seconds of stereo in under a second on an A100, 800,000+ training files) was serious work, not a demo.
- + Small, readable codebases (three repos total) are easy to audit and fork for research or product prototyping.
Cons
- - The project is dormant: my GitHub API check on 24 October 2026 showed no repository push since April 2024 across the whole organization.
- - There is no hosted product, no UI, no VST, and no inference API — the only entry points are Google Colab notebooks aimed at ML engineers.
- - No support channel exists: no Discord, no email, no committed issue triage; questions go into a void.
- - harmonai.org is a static page that never updated to reflect the move of Stable Audio to Stability AI, and its marketing slogan oversells what is a code drop.
- - Colab notebooks built against 2023 dependency versions will hit compatibility friction with today's runtimes before generating anything.
Krisp
Pros
- + Two-way noise cancellation held up against a mechanical keyboard and street noise in my test — far side reported clean audio
- + Works under Zoom, Teams, Meet, Discord and phone calls as a virtual device with no meeting bot
- + On-device processing for noise cancellation; fully private on-device transcription at Enterprise tier (krisp.ai/pricing)
- + Core at $8/user/month billed annually includes unlimited noise cancellation and an unlimited bot-free note-taker
- + MCP integration (Claude, ChatGPT, Cursor, custom) makes meeting data queryable from AI clients
Cons
- - No ongoing free plan — a 7-day trial only, then $8-16/user/month depending on billing (krisp.ai/pricing, Scribbl)
- - 8-12% CPU during active calls in my testing — noticeable on older hardware alongside video and screenshare
- - Action-item extraction produced generic entries without owners or dates in my sessions
- - Storage caps of 10GB (Core) / 60GB (Advanced) will bind heavy recorders
- - Accent conversion (1 hr/day on Core) is technically impressive but ethically loaded — enable it deliberately
