AI tools for streamlining various stages of SDLC

A lot of tools have come out for streamlining the development stage of SDLC (e.g. Github CoPilot, Tabnine, etc.) which have gained extensive adoption. I want to know if there any similar AI tools for streamlining other parts of the lifecycle (like planning, testing, deployment, etc.) which you/your team has found useful.

PS: I'm working on a devtool for making API testing autonomous (i.e. should work end to end with minimal human intervention). It's still very early, but please take a look if it sounds interesting to you and any feedback is appreciated!
