The musician's app for stem separation, practice and mastering
Split any track into up to 27 isolated stems including vocals, drums, bass, guitar, piano, keys, winds and strings.
Slow the speed without changing pitch, transpose the key, loop sections and mute or solo your part while you play along.
Automatically detect the chords in a song and transcribe lyrics so you can learn songs faster.
Arrange, record and edit the same session with bandmates or producers in real time, right in the browser.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
