CoreAI is a free AI chat app with more than 300 AI models in one place. Talk to models from OpenAI, Anthropic Claude, Google Gemini, Meta Llama, xAI Grok, DeepSeek, Mistral, Qwen and Perplexity without installing five different apps or paying for five subscriptions.

New models appear in CoreAI automatically as providers release them, usually the same day. If you keep hearing about some new AI and want to try it, it is probably already in here.

WHAT YOU CAN DO

AI chat
Pick a model and start asking. Replies stream in as they are written, and you can switch to a different model mid-conversation without losing the thread. Sign in and your chat history follows you across devices.

Search the live web
AI Search Mode answers with current information from the internet and lists its sources under every answer. Good for news, prices, sports and anything newer than a model's training data.

Compare AI models side by side
Send one prompt to several models at the same time and read the answers next to each other. It is the quickest way to find out which AI is actually good at your kind of question.

Ask about your files
Attach photos and PDF documents to any chat. CoreAI reads them and answers questions about what is inside: contracts, receipts, homework, lecture slides, reports.

Use 33 built-in AI tools
Each tool is a small workspace tuned for one job. Deep Research writes long, sourced reports. AI Writer drafts essays, emails and posts. Code Assistant explains and debugs code. Summarizer shortens long documents. AI Translator covers 100+ languages. Problem Solver works through math step by step. There are also tools for legal documents, nutrition, taxes, hiring, real estate, farming and freight.

FREE TO START, NO ACCOUNT NEEDED

Open the app and use it as a guest. You get free AI chat every day, and watching a short ad adds more messages. A free account is only needed if you want your chats synced across devices.

Pro, Premium and Max plans remove ads and unlock every AI model and every tool, with higher usage limits. Prices are always shown in your local currency before you commit to anything.

PRIVACY

Your conversations stay on your account and are never sold. Guest mode works with no sign-up at all, and Google or Apple sign-in is there when you want it.

Students use CoreAI as a homework helper, developers as a coding assistant, writers as a second pair of eyes, and plenty of people just ask one question to three models and see who gets it right. It is the one AI chatbot app that has every model.
