Stop juggling tabs and guessing which AI model is best. Nexim AI Playground puts Gemini, OpenAI, and OpenRouter (Llama, Claude, DeepSeek) into one simple workspace. You can tweak system prompts and temperatures side-by-side to see real-time results. Best of all? Your API keys stay local to your browser, so your data stays private. It tracks tokens and speed for you, making prompt engineering feel less like a chore and more like a breeze. It’s AI testing, but actually organized.
Hey Product Hunt! 👋
I built Nexim AI because I was tired of the "guess and check" game with prompts. Real prompt engineering is about more than just the text—it’s finding that sweet spot between the model, system instructions, and temperature.
Most tools make you switch tabs to compare. With Nexim, you can run a temperature split test (0.2 vs 1.2) or see how Gemini handles a prompt vs. DeepSeek side-by-side. It’s fast, your API keys stay safely in your local storage, and OpenRouter support means you can test almost anything.
Give Compare Mode a spin and let me know: what parameters should I add next? 🚀
