  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?

  Access Gemini Pro, Claude Pro, ChatGPT Pro models and more for $8/month. Is it another AI/LLMs wrapper? Yes. So why should I use it? Honestly right now there are a lot of other alternatives. But here's why I think it's useful enough to release it in early access: 1. Clear & transparent pricing model. Usage rates is the same is providers api rates + 10%. 2. LLMs responses don't rely on the client connectivity. We use Convex. It's super stable. You can even run multiple chats in parallel. 3. Use it if you like the design :) 4. We have a very clear roadmap. What's next? A desktop app…

  Another LLM Chat App to avoid having 10 different subscriptions and MCP2025 · donsir.com · ▲18

  This is like ChatGPT but simpler, with less features (for now). It offers unlimited access to o3, Claude Sonnet 4 and other models for the pro plan. It offers access to o4-mini and the like for the free version. Requests are unlimited up to rate limits that we hope apply to less than 2% of users (they're transparent and can be seen on the account page). I was sick of having these like t3.chat or abacus.ai that give you very few messages for the $8-$10 / month subscription, so wanted to create something closer to Cursor's new pricing but transparent. Image generation will come soon, I…

  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…
