Online music studio with synthesizer, effects, and recorder. Play a virtual keyboard, apply reverb/distortion/delay, and record your sessions. All in the browser. Effects chain in real time rather than on export, so you hear the reverb or delay while still playing.

Collaborative virtual whiteboard with a hand-drawn feel. Open-source Miro/Figma FigJam alternative — real-time collaboration, offline support, and end-to-end encrypted rooms.
