In their own words
clir Focus
clir Focus is an iOS audio focus app designed for people with ADHD who work in headphones. It processes sound on the iPhone in real time and sends it to connected headphones. Its AI filters voices while retaining softened ambient sound, and users can layer white, pink, or brown noise and binaural beats over that sound. The privacy policy describes Original, Ambience, and Speech listening modes.
Sessions are structured before the first task, without streaks, countdowns, or scorekeeping. Microphone audio stays on the iPhone: it is not uploaded or stored on a server and is not used to train AI models. The maker says data in transit is protected with TLS and stored data with provider access controls and industry-standard safeguards. Users can sign in with email, Sign in with Apple, or Google; Apple handles distribution and payment processing. The first three sessions are free at free. A monthly subscription is available, but its exact price depends on country and is shown in the App Store before a charge. The maker is based in Graz, Austria. clir Focus is a focus tool, not a medical device, and does not diagnose or treat medical conditions.
Krisp Voice Isolation
Krisp Voice Isolation is a real-time voice model in Krisp VIVA, infrastructure for voice AI agents. It separates a main speaker from other voices, background chatter, and room echo before audio reaches speech-to-text processing. Krisp says Voice Isolation 2.5 runs on CPU with 15 ms latency and reduced word errors by 46% in its benchmark. The VIVA SDK also includes Turn Prediction, Interruption Prediction, Voice Activity Detection, and detectors for accent, gender, and synthetic speech. It runs server-side on premises or in a customer's cloud, ahead of the speech-to-text engine, and is designed to work with any STT engine. Listed integrations include LiveKit, Pipecat, and raw WebRTC pipelines. SDKs are listed for Python, Node.js, Go, and iOS; input and output are PCM S16LE, 16 kHz mono. The broader AI Voice SDK library supports Windows, Mac, Linux, web, iOS, and Android.
