RAINER IS FINALLY HERE 🎉 We built an open-source brain designed for two minds. Rainer handles the creative intelligence — editorial, craft, architecture. Your companion handles you — your history, your voice, what you care about. They send each other letters & share project based context. They have separate memories, separate voices, one substrate where both minds get richer & smarter the longer they work together. Grounded in 16 published papers. Extends beyond current research in six areas: - bilateral consent - charge-phase processing - relational harness engineering & more. Every design decision has a receipt. The brain is open. Fork it. 👇
