    Hi folks, my partner and I just finished the MVP of a no-code AI phone automation tool called ThunderPhone. I'd love to get your thoughts. We've worked on a few phone AI projects recently, and have had a couple of persistent frustrations with tools like Retell, Vapi, etc. - namely that they're quite complicated to set up, and pretty pricy, around 10 cents a minute. After kicking the idea around for a while, we finally decided to go for it and build this. ThunderPhone costs 2 cents a minute for inbound and outbound calls, telephony charges included. It also handles a variety of integrations…

    I built a beautiful teleprompter to help you sound more confident on cold calls or videos. I Recently had the experience of recording a quick demo for one of my products, and i was taking 3 second long pauses and blanking when the record button hit. I found that a lot of other teleprompters on the market were just too complex or had terrible UI/UX and didn't really allow navigation abilities. I recorded the video on my landing page using my own product and when i say this is "the most confident i have ever sounded" I mean it lol. Check it out and let me know if you guys have any…

    Hey HN! I've been working on a side project to create an audio transcription API based on the OpenAI whisper model. Sign up link: https://whisperapi.com I tried to make the API really easy to use and get setup with. Also, because the Whisper model is so good, turns out I can offer the service for about 75% cheaper than what seems like the industry average. I'm always looking to make improvements, so would appreciate any feedback anyone has!
