About
Flat is a powerful yet beginner-friendly music notation platform that brings professional composition tools into the browser. Whether you're writing a full orchestral score or a simple guitar tab, Flat provides an intuitive interface that keeps the focus on your music rather than the software. At the heart of Flat is real-time collaboration — multiple users can write and edit the same score simultaneously across web, iOS, and Android devices, with changes syncing instantly. Its complete notation suite covers chamber scores, solo tabs, and everything in between, with customizable layouts, styles, templates, and 180+ instruments including 90+ high-quality studio-grade sounds. Flat supports offline composing with automatic sync when you reconnect, PDF import, YouTube/SoundCloud/MP3 audio uploads, and advanced playback controls for part volumes and reverb. Users can explore over 100,000 community-created scores, join monthly challenges, and get feedback from a global musician network. Flat also offers dedicated products for education (Flat for Education), Google and Microsoft tool integrations (Music Snippet), and website embedding for interactive sheet music. A REST API and Import API extend its utility for developers. It's ideal for students, educators, hobbyist musicians, and professional composers looking for a collaborative, cloud-native notation experience.
