Show HN: A $25 DIY alternative to $159 AI voice recorders – BYOK or local

A maker has launched Zeph, a $25 DIY alternative to $159 AI voice recorders, offering push-to-talk voice input into any app system-wide with bring-your-own-key or local operation. The device keeps audio and state on-device by default, encrypted with no cloud round-trip required, and displays agent signals such as rate limits, CI status and approval requests on an always-on face. Zeph ships with one SDK for sandboxed WASM apps portable across every Zeph board, with team features including bulk provisioning, SSO and policy listed as coming soon.
