Audio becomes text
Every audio and video that comes in or out of your WhatsApp becomes a text message in the same chat, in seconds.
You read, you don't listen
Every audio and every video that arrives on your WhatsApp becomes text in the same chat, right below the media, within seconds.
It also works for what you record: the text shows up for you and for whoever received it.
In the chat, on both sides
The text arrives with a visible label, like "Transcription:", so both the sender and the receiver can see that message came from LangZap.
The person on the other side doesn't need LangZap, doesn't install anything, and doesn't pay anything to see the text.
On your phone and on your computer
The transcript is a real message: it shows up on WhatsApp Web and Desktop, the same way it does on your phone.
Copy it, paste it into another app, forward it, or paste it into a conversation with the AI you use to ask for a summary or a reply.
Video too
Video with speech gets the same treatment: the text of what was said shows up in the chat, right alongside the video.
The plan's limits
Each file can run up to 20 minutes. The plan includes 400 minutes of transcription per month. Format and language details are on the Formats page.
