About this launch
Sentien is a context AI platform that transforms ambient audio into actionable structured data. It detects sound events, identifies the type of scene, infers activities, and provides emotional context—all from a single pass over the audio. Available as an API and web app, Sentien returns results timestamped and tagged with confidence values, enabling products like wearables, AI assistants, robots, and research tools to understand what is happening around users rather than relying on text or tap inputs. Built for real-world EEG and biosignal research, it also serves security systems, smart spaces, and devices that need environmental awareness.

Shopper questions
What is Sentien?
Sentien is a context layer for audio that takes a recording or live microphone stream and returns a structured description of what is happening in it: the sounds that occur, the kind of place the audio was captured in, and the activity going on around it. It is available as an API and a web app.
What can Sentien understand?
Sentien identifies multiple layers of context from the same audio: sound events and when they occur, the type of scene the recording is in, and the activity taking place. Each result includes a confidence value so you can decide how much weight to give it.
Can I use Sentien in my own product?
Yes. Sentien is designed to be called from your own software. You send audio, either uploaded or streamed, and receive context back as structured data such as JSON or CSV, which can feed into whatever your product already does.
What makes Sentien different from a regular audio classifier?
A classifier assigns a clip one label from a fixed set, whereas Sentien returns several layers from a single pass over the same audio, each timestamped against the signal. A sound that is ambiguous on its own can be interpreted against the scene it occurred in.
