Show HN: Exro – I got tired of cleaning up copy/paste between apps

Between Slack, Claude, GPT, and Gmail, I'm constantly making formatting changes: deleting timestamps and Slack's (edited), making API fields inline code, removing weird highlighting, etc.

I tried changing this with prompts, but for things like formatting rules, it didn't get applied consistently.

So I built Exro. It scans the pasted text and applies deterministic changes with no grammar/copy changes whatsoever. You can paste something in and try it directly. Let me know if you have any suggestions!
