Serpaix vs Plaud
A recorder captures the room. Serpaix remembers the work.
Plaud sells dedicated AI voice recorders — Plaud Note, NotePin and Note Pro — that transcribe through a cloud subscription (a free tier covers 300 minutes a month, Pro is $17.99/mo and Unlimited $29.99/mo). It is hardware-first and cloud-processed. Serpaix uses the machine you already own, transcribes locally with offline Whisper, and keeps the resulting memory on your device instead of behind a subscription.
In short: Serpaix and Plaud 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 meeting and voice capture to become part of a private, searchable knowledge base on your own PC, without buying a device or paying per transcription minute. Choose Plaud if: you want dedicated hardware for in-person recording — a pendant or card you can wear — and you are happy with cloud transcription and a monthly subscription.
