Second Brain Keeps a Memory in Your Inbox
An email-based personal archive that saves articles, notes, and forwarded messages, then answers questions from the record you build.
Field notes
The service accepts articles, notes, and forwarded email as its archive input, then returns brief replies to requests for recaps, connections, or a second view. Its record is described as readable, exportable, and arranged like a small personal vault rather than a proprietary dashboard. Signup starts by emailing signup@secondbrain.email with a description of the intended use. The visible pricing offers ten lifetime messages free, followed by $8/month for 150 messages per cycle or $25/month for unlimited messages.
