  • How Machines Hear and Understand Us
    It’s about value—saving time, money, and effort. Traditional transcription services charged $1-2 per audio minute. Imagine needing 10 hours transcribed—that’s $600 to $1,200, just to get your words on paper. With tools like Assembly AI charging $0.015 per minute (that’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 / 10 months ago

    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: over 2 years ago

  • Building a self-creating website with Supabase and AI
    Creating AI speech isn't that difficult thing to do, however it is a bit challenging to find an API that doesn't cost you your kidneys. Luckily I ran into Unreal Speech which has some pretty generous free monthly tier. However it will not suffice for us to run the site generations for a over month, so I'll need to do some tricks here and there to keep things running (or just open up my wallet). - Source: dev.to / over 1 year ago
