Show HN: Lightrail – use GPT-4(V) to ask questions and edit code across apps

I've been working on Lightrail for a couple months now, just added gpt-4-vision-preview support and figured it was as good a time as any to do a Show HN. It's still very rough around the edges, but I'm hoping it can provide a compelling alternative to siloed per-app AI assistants. So many of my favorite AI workflows involve working across apps, so I wanted to build something that made those workflows easy -- and that can support a community of new integrations and workflows/actions that are simple to throw together. Would love to hear feedback & happy to answer any questions!
