Hi HN! I built LLM OneStop (https://www.llmonestop.com), a unified interface for accessing multiple AI language models in one place. The main problem I wanted to solve: constantly switching between different AI platforms, managing multiple subscriptions, and losing conversation context when comparing outputs across models. Key features:

Switch between GPT-4, Claude, Gemini, Llama, and other models mid-conversation Compare responses side-by-side Single interface instead of juggling multiple tabs/subscriptions Free tier available to try it out (no credit card needed) "Connect" plan lets you bring your own API keys for unlimited usage

I built this because I found myself constantly copy-pasting prompts between ChatGPT, Claude, and other platforms when I wanted to compare responses or find the best model for a specific task. You can try it right now with the free tier - would love to hear your feedback on what works, what doesn't, and what features you'd like to see!
