AI Insights for Substack Chat: bring your own key, keep your privacy

A one-click summary button I added to my Substack Chat client. Reads your visible feed, sends it to OpenAI / Anthropic / Google with your own API key, returns a structured summary.

I spend a lot of time in Substack chats with hundreds of messages a day. The good ones are dense — three or four traders thinking out loud, names, tickers, theses, half-formed ideas. Catching up after dinner means scrolling through 800 messages to figure out what mattered. That’s not reading. That’s archaeology.

So I added a button.
