Sing2Notes review
A flexible vocal transcription tool with mobile access and practical notation exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sing2Notes is an AI-powered transcription tool from Klangio GmbH for singers, musicians and creators who want vocal recordings converted into written notation. It supports automatic vocal melody transcription as well as vocals alongside other instruments. Users can upload audio, paste a YouTube link or record directly, then review notes through a piano-roll display and edit the transcription in the browser or mobile app. The product is available on the web, iOS and Android, with synchronized access across platforms.
The free plan provides unlimited demo transcriptions, but each song is limited to 20 seconds and the generated sheet music is available for preview with PDF download. Sing2Notes Pro raises the limit to 15 minutes per transcription and includes 50 full transcriptions per month, unlimited demo transcriptions, full PDF downloads, MIDI and MusicXML exports, and browser-based editing tools. The monthly plan is $14.99 per month, while annual billing is shown at a $6.24 monthly equivalent. This makes the free tier useful for short trials, while regular transcription work is centered on Pro.
Sing2Notes fits workflows that move between recorded audio and digital notation. Its supported inputs include MP3, WAV, MP4, MIDI and FLAC, and it accepts links from YouTube, Instagram and TikTok. Quantized and unquantized MIDI exports provide different levels of rhythmic interpretation, while MusicXML supports notation-focused workflows. Choose Sing2Notes if vocal melody capture, editing and mobile synchronization are priorities. It is less suitable for users who need unrestricted full-song transcription on a free plan or more than 50 full transcriptions per month.
