They're all good products, but none of them did what I needed.
NBot and Syft are close to what I wanted, but NBot only sends notifications inside its own app, and Syft only works on mobile. I needed updates in Slack where my team already works.
Follow is a great RSS reader, but it's still a reader. I don't want to open another app and scroll through a feed. I want updates to come to me.
Tailor and Nuse are more like AI news apps. They pick what to show you. I wanted to choose my own sources and write my own filtering rules.
SignalHub is the only one that lets me do all three: pick my exact sources, set my own AI filter, and get notifications in 10+ channels including Slack, Discord, and Telegram.
