Show HN: Skim – a minimalist open-source email client for Windows (MIT)

I built Skim because I was super dissatisfied with all existing Windows clients.

I mean, it's not a rocket science, there should be some lightweight modern solution, isn't it? So I decided to create a client that just, you know, MAKES SENSE and has design younger than dinosaurs.

Key points:

* Obsessed with installer size: it should be under 5Mb.

* BYOK AI. Cowriter, agentic search, summarization and other AI stuff is powered by your own key for Anthropic/Openrouter, or you can connect your own OpenAI-compatible server (including local)

* No bloat. It should be as contextual as possible: gives you right button when you need it. No menu at all. No integrations. Just email.

* Instant startup, super modest on resources

* Cool warm zine design with paper colors and really calming vibes

It's MIT - contribution and stars are welcome!
