Everything you might want to know about Multi AI Summarizer
You enter one question. We send it simultaneously to several AI models, wait for their answers, then run a synthesis step that merges them into a single response — keeping points the models agree on, surfacing where they differ, and dropping repetition.
On the free tier: Google Gemini, Mistral, and open models served by Groq (such as GPT-OSS). Providers rename and retire models often, so the app auto-selects a current one from each — when a model goes away it simply moves to the next live one, so it keeps working. OpenRouter (DeepSeek and other free models) is an optional extra. Cohere and Nvidia NIM can be added with your own free key from those providers, and premium models — ChatGPT, Claude, Perplexity, and Grok — with your own paid key.
Google's terms don't allow Gemini's free tier to be offered to people in the European Economic Area, Switzerland or the United Kingdom, so we leave it out for visitors there. You can still include Gemini by adding your own Gemini API key under "Use your own API keys".
Yes. The default models run on free-tier AI APIs, and the Service is supported by ads. There is no signup required to use the default models. The Service is for adults (18+).
Free-tier models have usage limits and can stop mid-response. When that happens we build the summary from the models that finished, so you still get an answer.
Often, yes — for factual and reasoning questions. When several independent models converge on the same answer, your confidence should go up; when they diverge, that is your signal to dig deeper. It is the same "ensemble" idea that improves accuracy in machine learning.
If you are not signed in, we do not store your questions or the AI answers — they are processed in memory for your session and are not saved to any database. (A short-lived in-memory cache speeds up repeated identical questions; it is not personal and clears when the server restarts.) Signing in is optional; if you create an account we store your email and basic profile so we can sign you in, handled by Google Firebase. If you are signed in, your conversations are saved to your account (via Google Firebase) so you can return to them, and you can delete them anytime — see our Privacy Policy.
Yes — code questions get syntax highlighting and copy buttons, and the synthesis preserves code blocks from each model.
Yes — attach PDFs, Word/Excel documents, or text files with the 📎 button and they are sent as context with your question.
