  ChatHawkOct 2025 · chathawk.co · ▲13

  I kept pasting the same question across several AI platforms to make sure I got the best answer. I found this process time-consuming, and difficult to compare the answers between platforms. So I built ChatHawk. It's a tool that lets you ask a question and have it answered by all the flagship AI models at once. These models are currently Gemini 2.5 pro, GPT-5, Grok-4 and Claude: Sonnet 4. ChatHawk also uses AI to get the best parts from each response to provide a 'Best of All Models' answer. I've found it useful for these use cases: 1. When you want to make sure the answer is right. E.g. for…

  I built an LLM chat app because we shouldn't need 10 AI subscriptions2025 · prismharmony.com · ▲58

  I'm lost between ChatGPT vs Claude vs Gemini... which subscriptions to take? With Cursor and all these specific AI tools, I just wanted one simple chat app where I can use any model and pay only when I use it. Couldn't find one, so I built one. Pay only for what you use. Your prompts and docs, knowledge bases work with every model - no more copy-pasting between apps. Started as a personal project, but thought someone else might benefit from this too. https://prismharmony.com/chat What do you think?

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
