ThunderPhone
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…

ByePhone- An AI assistant to automate tedious phone callsFeb 2026 · byephone.io · ▲5I have a bit of phone anxiety, and have a ton of dread around making phone calls to restaurants, banks, doctors, and so on and on. I thought: AI could do this with a web form turned into a prompt. Stack started out simple -> using 11labs for voice + claude + twillio, but it actually got rather complex (even though I tried vibe coding most). First off, finding the phone numbers quickly is hard. This is done by scraping the web with some basic duckduckgo search and structure with openai calls. Second, collecting the right information. I’m still struggling a bit with this but the architecture…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
