What they are
Fireflies
Fireflies is an AI meeting assistant that deploys a bot named Fred into your Zoom, Google Meet, Teams, or Webex calls to record, transcribe, and summarize conversations automatically. It builds a searchable archive of your entire meeting history, extracts action items, and on Business plans pushes notes directly into Salesforce or HubSpot. The free tier is usable for light testing, but the 800-minute storage cap and limited AI credits make it impractical for daily professional use.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
