Coolso

Coolso develops wearable gesture-recognition technology. Using patented sensing that detects muscle-vibration signals processed through its own AI model, Coolso recognizes individual finger movements and strength levels with low-latency response, from a wrist-worn device or an ordinary smartwatch's accelerometer and gyroscope without dedicated hardware. Founded by Sheng-Kuei Hsu, Wei-Lin Lee, and Jack Wu and based in Cambridge, Massachusetts, the seed-stage company is backed by 500 Global and Alchemist Accelerator and targets AR/VR interaction, with potential expansion into medical rehabilitation and sports equipment. Coolso publishes no public API, SDK, or developer portal at this time.

Coolso is profiled on the APIs.io network. Tagged areas include Company, Wearables, Gesture Recognition, Artificial Intelligence, and Sensors.

Coolso’s developer surface includes engineering blog, support, and 2 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/coolso: open an issue to ask a question, or submit a pull request to add artifacts.
