About
NutifAI is a browser-based AI music transcription tool designed for musicians, educators, and music producers who want to convert audio into readable, editable notation without complex software. Users can upload local audio files (MP3, WAV, FLAC, M4A, AAC, OGG up to 50MB) or paste YouTube and Spotify URLs to instantly extract and process music. The platform uses advanced AI models to analyze tempo, key, harmony, and texture before separating and transcribing individual instrument stems — including piano, vocals, bass, drums, guitar, and more. Transcriptions are exported as PDF sheet music, MIDI files, and MusicXML documents, making them compatible with most DAWs and notation editors such as MuseScore or Sibelius. A standout feature is the stem-aware processing engine, which lets users target specific instruments for isolation and reuse previously generated stems to save processing time on retries. The lyrics and karaoke mode extracts vocals and generates practice-ready mixes. Automatic structure detection helps musicians align sight-reading sessions or ensemble arrangements. NutifAI offers a transparent and privacy-conscious design with sanitized logging and configurable rate limits. A free tier with starter credits is available to all users, with additional credits purchasable for heavier usage. It is ideal for music students, arrangers, producers, and educators who need a fast, AI-driven path from audio inspiration to shareable notation.
