Most developers guess why their CUDA code is slow. I wanted answers, so I built RightNow AI.

It’s a GPU-first editor that:

Profiles your kernels live without leaving the editor

Lets AI rewrite and tune them for your exact GPU

Autocompletes based on your hardware, not generic code

Supports multi-GPU setups out of the box

Works with local or cloud LLMs

In tests, we’ve seen up to 180× speedups on the same machine with no manual tuning.

Beta is open now, and we’ll open source it soon once it’s stable.
