- Listen to audio messages at 1.5x, 2x, & 3x speed to save time
- Have audio messages and voice notes transcribed so you can listen while you read them
- Search through audio messages
- Use your voice and tone to convey your meaning so it's not lost in translation

Finally! What a time saver

I just hate writing texts and having to correct them. Now all I do is record and they are transcribed for me
