Nice! Just took a look. It seems we are attacking the same beast (newsletter fatigue) but maybe with different flavors.
I went down the route of using Gemini 3 specifically to generate 'strategic briefs' rather than just a feed. Curious what stack/models you're running for Hidden Signal?
It’s Django with a similar custom email that you can forward emails to or sign up through that email. And then uses open AI mini for summarization and nano for categorization. Then it sends you a digest with the summaries on your schedule.
