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?
Nice work!
Built this over the weekend because I subscribe to too many newsletters (Lenny's, Tomasz Tunguz, Data Driven VC) but never read them.
It's a Python/FastAPI backend that accepts forwarded emails, processes them with Gemini 3 (using its large context window), and stores results in Supabase to generate a structured Sunday briefing.
Right now it's an MVP. I'm looking for feedback on the summarization quality vs the original emails.
You can try it here: https://sunday-dashboard.streamlit.app/ (It generates a unique email address for you to forward newsletters to).
