Kaption AI

People who get a lot of voice notes on WhatsApp and would rather read than listen are the obvious audience for Kaption AI.

Kaption AI is an audio-to-text and transcription tool that turns WhatsApp audio messages into written text, and it works on WhatsApp Web.

That suits a busy workday, a noisy commute, or any moment when playing a clip out loud is not an option.

The tool also produces AI summaries of chats, so you can catch up on a long thread without scrolling through all of it.

Kaption AI adds a privacy mode and passkey locks to WhatsApp Web as well, which matters if you use a shared or office computer.

The company positions it for both personal and professional use, including people who handle client conversations on WhatsApp.

The focus is narrow: it does one job inside one messaging app, and that is its main appeal and its main limit.
