  • How Machines Hear and Understand Us
    Itโ€™s about valueโ€”saving time, money, and effort. Traditional transcription services charged $1-2 per audio minute. Imagine needing 10 hours transcribedโ€”thatโ€™s $600 to $1,200, just to get your words on paper. With tools like Assembly AI charging $0.015 per minute (thatโ€™s $0.90 for an hour), the cost drops dramatically. For companies dealing with large volumes of audio, this is a game changer. - Source: dev.to / over 1 year ago
  • We Created Something Cool to Help Streamers Grow, What Do You Think? DailyClips.io
    The auto caption is from assemblyai.com, they do a pretty good job. As for manual, you can do `Add Layer` > `Text` from the short-form editor then trim each text layer. Its slow going though. Ideally we will figure out a better interface and build it. For now I recommend using the auto caption, then modifying it to your liking, if there is more than a few words it will probably be faster. Thanks for the kind words! Source: about 3 years ago
