ThreadRecap vs Letterly
Letterly is a voice app that turns speech into notes, messages and posts. ThreadRecap reads a whole WhatsApp export and writes out every voice message in the place it was sent.
- Photos & videos stay on your device. Audio sent for transcription only if you opt in. If you select a video, your browser extracts and sends only its audio track for transcription; the video and its visual content stay on your device.
Your Own Voice vs a Whole Conversation
Letterly answers: "How do I turn what I just said into clean text?" You dictate or record, and it rewrites the words as a note, an email or a post. It runs on iPhone, Android, Mac, Windows and the web, detects more than 90 languages, and handles recordings up to 90 minutes.
For a WhatsApp voice message, Letterly's own guide works one message at a time: hold the message, tap Forward, then Share to Letterly. That suits the voice message you just received.
ThreadRecap answers a different question: "What was said across this whole chat?" You upload the export once. Every voice message is transcribed where it was sent, beside the written messages, with the sender and the time, and the conversation downloads as one file.
