How it works

Plug in. Talk. Done.

Four steps, and three of them happen in about a second.

  1. 1

    Plug it in

    The built-in USB-C connector goes straight into your phone. Lightning iPhone? Use the cable in the box.

  2. 2

    It connects

    Automatically. Your phone powers it, so there is no battery and no Bluetooth to pair.

  3. 3

    Open the app

    Pick your languages in the PlumCat app and choose a mode.

  4. 4

    Talk

    Hold to talk, release to translate. Look at the person, not the screen.

The honest bit

PlumCat plugs into your phone and your phone powers it, so it needs your phone and the PlumCat app. Online languages and AI features need internet. The 30 offline languages work without signal.

The mic

Built for loud places.

An independent noise-cancelling mic, built with DNN single-mic voice extraction and computational auditory scene analysis. It is designed to filter background noise and pick up clear speech in markets, lounges, outdoors, exhibitions and restaurants, with 4 m pickup.

Design

From sketch to capsule.

One small aluminium-alloy capsule, drawn part by part, then shaped to wear as a pendant, a bracelet or clipped on. The connector sits in the capsule, so it plugs straight into your phone.

A6

Record it. Mark it. Read it later.

Press the button while recording to mark the last 10 seconds. The A6 turns the recording into text, with marked passages in purple, then pulls out key points, to-dos and a mind map.* It also translates Word, PDF and Excel files and keeps the formatting.

*Transcription, AI summary and mind map include 300 minutes per month each.
