Yes, I vibecoded small personal apps from start to finish with it. Planning mode, edit mode, mcp, tool calling, web searches. Can easily switch between Gemini, ChatGPT, Grok or Claude within the same conversation. I think multiple agents work, though not sure.

All under one subscription.

Does not support upload / reading of PDF files :(

> Can you agentic code with it?

Yes, definitely. I use it mostly in Agent mode, then switch to Ask mode to ask it questions.

> How's the autocomplete?

It works reasonably well, but I'm less interested in autocomplete.
