Multi-AI

Chat with ChatGPT and Gemini in the same room. Ask once and get multiple perspectives at the same time—for study, work, brainstorming, or everyday worries.

MultiAI is a group chat–style AI app that lets you talk with multiple AI assistants—such as ChatGPT and Gemini—in the same room. Ask a question once and get different perspectives at the same time, instead of going back and forth with each AI separately.

Use it for:

Homework and assignments Brainstorming ideas or polishing documents for work Talking about something that happened today Everyday questions like cooking, travel, or life advice ■ Key features Multiple AIs in one chat room

Invite both ChatGPT and Gemini into the same room, together with you. One message from you can trigger replies from multiple AIs, so you can compare answers and think more deeply. Switch between “both / ChatGPT only / Gemini only”

For each room, you can choose: Both (ChatGPT + Gemini) ChatGPT only Gemini only For example: use both for broad brainstorming, then switch to a single model when you just need to refine the final wording. Personalization

Set your profile (age, occupation, background you want AI to know) and response style (tone, role, attitude). e.g. Profile: “I’m a 21-year-old university student.” e.g. Response style: “Please answer as a general/mentor.” Once set, your profile is taken into account across rooms, so you don’t have to repeat the same self‑introduction every time. Message search

Search your past conversations by keyword. When you think “What was that advice again?” you can quickly find the exact message where it appeared. Images and files (for subscribers)

Attach photos or PDFs and ask questions about their content. Useful for things like credit card statements, documents, and long texts you want summarized or explained. ■ Free to try & subscription Free tier

You can send a small number of text-only messages for free. This lets you try the app and see how the AIs respond before subscribing. Paid plan

Monthly subscription with a generous soft limit on the number of messages (designed around roughly 1,200 messages per month with 10 round-trips of history). Enables photo/file attachments and other richer features. You can manage or cancel your subscription at any time from your Apple ID (App Store) settings. ■ Safety and data handling Your conversations are stored on the server so you can continue across devices with the same account. AI responses are generated via APIs provided by OpenAI and Google (Gemini) and are handled according to their privacy policies. AI can make mistakes. The app clearly reminds you of this, and important decisions should always be made at your own discretion. ■ Recommended for Students who want help with homework, reports, and studying Working professionals who need support with brainstorming, drafting, or reviewing text Anyone who wants someone (or rather, multiple AIs) to casually talk to about daily worries People who prefer to compare several opinions at once before making a decision MultiAI is like a group chat where you + multiple AIs are always available. Use it to lighten your mental load, get fresh ideas, and make thinking and deciding a little easier every day.
