Transcribes voice messages directly inside WhatsApp Web chat bubbles, letting you read audio without playback. Zapleu, built by Thiago Dalle Dias de Paiva, is a Chrome extension that hooks into WhatsApp Web and shows in-bubble transcriptions while keeping processing on your machine. Key capabilities include local Whisper-based transcription, automatic mode for open conversations, and a searchable history. It fits professionals and meeting attendees who need quiet, text-first access to incoming voice notes.

What the extension does inside chats

Zapleu inserts transcribed text directly into the existing WhatsApp Web interface, presenting each transcription in the same chat bubble where the audio appears. It attributes messages to senders, including in group chats, and offers an automatic mode that walks through audios from newest to oldest in an open conversation. Supported languages include Portuguese, English, and Spanish, plus an automatic language-detection option.

How it behaves on typical hardware

The extension processes audio locally using the Whisper model and can use the computer's GPU to accelerate transcription when available. On first use it downloads a model package of roughly 250 MB that the extension stores in the browser. Because audio never leaves the device, transcription latency depends on local CPU/GPU performance rather than remote servers.

What it does for privacy and discreet use

Zapleu captures incoming audio before playback so you can read messages without sound, which the extension documents as a silent transcription workflow. Processing occurs entirely on the user's machine via the Whisper AI model, so audio files are not sent to external servers. The extension also keeps a searchable history and lets you export transcripts as a .txt file for later reference.

Compatibility and where it fits in a workflow

Available for Chrome and other Chromium-based browsers, Zapleu integrates with WhatsApp Web and complements a browser-based messaging workflow rather than replacing phone apps. The in-bubble presentation and history search suit users who prefer scanning text, while the extension's local model download and optional GPU use align it with users comfortable running AI tools inside the browser.

Clear tool for discreet, text-first consumption of voice notes

Zapleu is a focused extension that helps users read voice messages instead of listening to them; it targets people who need quiet, searchable access to audio content during work or meetings. The extension narrows WhatsApp Web toward text consumption rather than broad messaging management, so it suits users who accept a single-purpose enhancement rather than a multi-feature communication overhaul.
