Show HN: Hidden Signal – Newsletter digest with web dashboard and scheduling

I built this to solve my own newsletter overload problem. Turns out there are similar tools that I found after I basically launched (Meco, Mailbrew), but turns out mine is a bit simpler and less opinionated about how you consume content.

Core features:

- Three ingestion methods: auto-forward from Gmail, manual forwarding, or sign up with your dedicated email address

- Web dashboard to browse all newsletters in one place

- Scheduled email digests (configurable times, skips if nothing new)

- Save/star functionality for read-later

I've been using it for a few weeks, and it's really helped me. I set mine to arrive at 8am and 1pm. The save feature is nice, too.

Tech: Django, OpenAI for summarization, hosted on Hetzner. Email parsing is surprisingly gnarly—lots of edge cases with different newsletter formats. Free for now, likely paid tiers eventually. Feedback welcome!
