Hi Folks,
I kept running into the same problem while using ChatGPT. I was writing a prompt, then end up pasting it into multiple LLMs to compare responses.
So I built an app that does that for you—one prompt in, multiple LLM models respond to your query, side by side in real time.
What is it?
A tool for anyone who wants to compare outputs across different LLM models and quickly see results of all LLM models.
I have added following ChatGPT, Gemini and Claude for now, will add more models if users demand for it.
How it works?
- Enter a prompt, hit Submit, and watch responses stream in side by side.
- Save, edit and pin conversations.
- Full‑text search across all past prompts and responses.
- Bring your own API keys: add keys from each provider’s developer portal inside the app.
I originally built this for personal use, but I’m opening it up now.
If you try it, I’d love feedback—especially on the UX, missing models and features you’d want next.
Happy Prompt‑Maxxing!
