GPU development shouldn't require switching between five tools just to understand why your kernel is slow.

RightNow AI is the first GPU-native code editor. It brings real-time profiling, a cycle-accurate emulator, and AI that actually understands CUDA all in one place.Profile without leaving your code. Emulate H100s without the hardware. Ask optimization questions in plain english.

This is really a very great editor, packed with features. Also, the website is pretty cool. I really loved the text animations :)
