It serves GPT-5.1, Claude Opus 4.7, Gemini 3 Pro, DeepSeek V4, and Llama — all from a single chat window, with no signup or API key.

It's perfect for comparing model responses, brainstorming, or getting coding help. The curated model selection means you always get the best tool for the task. Visit https://askai.free and start exploring the future of AI, free.
2. Perplexity — AI Search with Citations
Perplexity (perplexity.ai) redefines research by blending chatbots with live web search. Its free tier uses a proprietary model or GPT-4o mini, and you can ask unlimited questions with citations. For power users, the Pro tier adds Claude and GPT-4, but the free version remains generous — no signup required for basic queries. It's ideal for verifying facts, getting source-backed answers, and saving time on deep dives. The only downside: the free tier limits the number of Pro searches per day, but the core search is always free.
3. Claude — Anthropic's Thoughtful Assistant
Claude (claude.ai) offers a free tier that includes Claude Sonnet 4.6 and occasional access to Opus. No signup? Actually, Claude requires a Google or email login, but no credit card. Once in, you get generous daily messages, projects, and artifacts (like code and documents). Claude excels at nuanced reasoning, long-form writing, and safety-conscious tasks. It's great for professionals who need a reliable assistant without hidden costs. The free tier is respectable, though heavy users may hit caps quickly.
4. Poe — Quora's Multi-Platform Chat Hub
Poe (poe.com) from Quora brings together GPT-4, Claude, Gemini, Llama, and countless community-created bots in one interface. It requires an email signup, but no credit card. The free tier gives you daily credits (e.g., around 3000 points) that refresh each day, allowing you to try many models. Poe's strength is variety: you can compare responses side by side or use niche bots for specific tasks. It's ideal for explorers who want to test different AIs without juggling multiple accounts. However, the credit system can be limiting for heavy use.
5. Groq — Blazing Fast Inference
Groq (groq.com) isn't a chatbot itself but an API that serves open-source models like Llama 3, Mistral, and DeepSeek at incredible speeds — up to 1,000 tokens per second. For developers, the free tier offers 10 requests per minute and 100 per day, no credit card needed. It's perfect for prototyping or embedding AI into apps. The trade-off: no chat interface, so you'll need to code. But if speed is your priority, Groq's hardware is unmatched. Non-developers might find it less accessible.
6. DeepSeek — Open-Source Power for Coders
DeepSeek (chat.deepseek.com) offers direct access to its V4 and Reasoner models — all free with no signup. Simply open the site and start chatting. DeepSeek is especially popular among developers for its strong coding abilities and long context window. There's no daily limit mentioned, though fair use policies apply. It's a no-brainer for coding help, explanation of technical concepts, or even creative writing. The only con: it sometimes hallucinates more than paid models, but for a free service, it's outstanding.
7. OpenRouter — API Gateway to 100+ Models
OpenRouter (openrouter.ai) is a unified API that gives you access to over 100 models from OpenAI, Anthropic, Google, Meta, and more. The free tier offers $5 in credits after signup (email required, no credit card), enough for extensive testing. It's best for developers who want to experiment with different models through one key. You can also use the web chat interface, but it's more limited. The pros: vast model selection and simple pricing. The cons: requires signup and the free credits run out.
8. Pi — Conversational AI with Warmth
Pi (pi.ai) by Inflection AI is designed for natural, empathetic conversation. It's voice-enabled on mobile and offers a web chat for free, no signup needed for basic use (full features may require a login). Pi excels at casual chats, emotional support, and brainstorming ideas in a friendly tone. It's not the best for coding or complex tasks, but its warmth makes it unique. The free tier is generous, with unlimited messages, though occasional ads appear. Perfect for those who want a companion rather than a tool.
