These tricks are a little too much for me. I'd rather just write the code myself instead of opening 20 tabs with different LLM chats each.

However, I'd like to mention a tool called repomix (https://repomix.com/), which will pack your code into a single file that can be fed to an LLM's web chat. I typically feed it to Qwen3 Coder or AI Studio with good results.
