In their own words
AIVoiceSeparator
AIVoiceSeparator separates songs into vocal and instrumental stems for backing tracks or clean vocals. Its Studio pipeline combines BS-Roformer, Mel-Roformer, and MDX23C, then applies EBU-R128 loudness normalization. The maker reports an SDR of 12.97 dB and says this is roughly 3 dB above the open Demucs baseline. The web app accepts audio and video files up to 100 MB and 20 minutes in formats including MP3, WAV, M4A, FLAC, OGG, WebM, Opus, and MP4/MOV. You can submit YouTube or SoundCloud links; TikTok clips must be saved and uploaded. Optional Whisper transcription returns SRT, LRC, and TXT files and adds about 30 seconds to processing. A REST API accepts a URL or upload and returns both stems. The free plan allows three songs per month when signed in; pay-as-you-go credits cost $0.50. The maker says uploads and results are deleted within 24 hours and audio is not used to train AI models.
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.

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.
