Ask HN: Programmable inbox with natural language rules

Hi hackers,

I’m building a tool that lets you tell your inbox what to do (once) and have it just work.

The idea is simple: instead of manually filtering, labeling, or replying to emails, you write a few natural language rules like:

### User - All emails from Cal.com with “Onboarding” in the title @read - All emails from a potential user inquiry @reply @doc("most-faq")

### Support - All emails from current users asking for help @reply @doc("support-guide")

The AI reads your inbox, learns from your rules, and applies them to every new email.

You can think of it like a personal scriptable inbox. No need to dig through settings or click filters, you just describe what you want, and the system handles the rest.

Curious what do you think about this? Will it be something helpful and people would pay for?
