Serpaix vs Omi
A pendant hears your day. Serpaix also keeps your work.
Omi is an open-source wearable pendant that listens continuously, transcribes in 25+ languages online or offline, and syncs to desktop, mobile and web apps. It is a genuinely local-friendly, open-source hardware take on conversation memory. Serpaix is the software counterpart: it captures from the computer you already work on — screen, clipboard, files, voice, notes — and organises it into a knowledge graph you can query and study from.
In short: Serpaix and Omi are both tools for organising what you know, but they optimise for different things. Serpaix is a local-first personal AI operating system — capture, knowledge graph, search and AI chat run on your own Windows PC, with cloud sync, mobile apps and enterprise SSO on the roadmap. Choose Serpaix if: you want your digital work captured and connected — meetings, PDFs, screenshots, notes and web pages — as one private memory on your PC. Choose Omi if: you want hardware that hears conversations wherever you go, including without a computer, and you value an open-source device.
