EchoFox is an AI transcription service that operates as a contact inside WhatsApp. People who receive long voice messages forward them to EchoFox and get the text back in the same chat, along with an optional summary. There is no separate app to install; the company says anyone with WhatsApp and an internet connection can use it.
The product was created by a founder named Fran, who describes receiving long voice messages every day and often having to listen twice to understand them. EchoFox was built to transcribe and summarize those audios so they can be understood and searched quickly. The company says more than 700 users rely on it.
Setup follows four steps. A user subscribes to a plan, adds EchoFox to their WhatsApp contacts, and sends or forwards a voice message to the contact. The transcription then arrives as a reply in the conversation.
If the message is long or hard to follow, the user can request a summary, which EchoFox says it uses to detangle audios longer than a minute. Most transcriptions are delivered within 10 seconds, and the company says delivery typically ranges from a few seconds to two minutes depending on audio length and server capacity.
On privacy, EchoFox states that it encrypts transcriptions, does not store the voice messages themselves, and keeps transcriptions for 24 hours so they can be summarized before deletion.
The core feature is transcription of WhatsApp voice messages, with automatic language detection across 90+ languages. EchoFox is optimized for English, Spanish, German, French, Portuguese and Italian at 95%+ accuracy, and supports up to 98 languages at 90%+ accuracy. These are the company's own figures.
Beyond voice notes, EchoFox accepts most popular formats, including ogg, mp3 and wav, and can process recordings with several speakers, though it is tuned for single-speaker messages. It also applies noise reduction for recordings made in loud places.
Transcriptions are searchable, so users can find key details without replaying audio. The Pro plan adds video transcription, and YouTube link transcription is listed as coming soon.
