A free tool to compare and combine AI responses
Multi AI Summarizer lets you ask a single question and instantly receive answers from several AI models side by side. On the free tier it queries Google Gemini, Cohere, Mistral, and Llama 3.3 70B (via Groq and Cerebras — Groq switches to GPT-OSS 120B after Aug 16, 2026), with optional Qwen, DeepSeek (via OpenRouter), and GPT-class models (via GitHub Models). Premium models — ChatGPT, Claude, and Perplexity — can be enabled with your own paid key. Instead of opening a dozen tabs, the Service does it for you and produces a single, intelligently combined summary.
Every AI model is trained differently. Some excel at creative writing, others at factual research, and others at programming. By querying several models at once, you get broader coverage, fewer blind spots, and reduced bias. Think of it as an "ensemble" approach — the same principle that makes the best machine-learning models work.
A Gradio frontend provides the chat interface, communicating with a FastAPI backend that dispatches your query to the selected AI provider APIs in parallel. Responses are collected and a summarization step combines them into a single output. The stack runs on Google Cloud Run with Cloudflare for DNS.
Built by an independent developer who prefers to stay anonymous and let the work speak for itself. I'm a software professional working in IT; I use AI tools heavily, on and off work, and that constant use is what gave birth to this idea. It has genuinely saved me time ever since — and if it does the same for you, sharing it with others would mean a lot.
