My most common use case is telegram integration via bot API - adding mobile controls to services that otherwise don’t have acceptable (for me) UI. I’ve also tried their LLM integration and tool node to create a simple agent that reaponds directly to messages, but for now it can only save links to my linkwarden instance. I found it acceptable and plan to add more tools. Basically, i want it to automatically decide what to do with stuff that i send to chat.

I can’t think of a use case, that couldn’t be realized in Bash instead.

Well, everything can be done in bash (or in python, more probably), but n8n makes it easier to tweak. With “batteries included” many stuff can be done without prior research and without external dependencies. They even added built-in databases in recent release.
