ChatGPT
Conversational AI assistant by OpenAI with multimodal reasoning, voice, and agent capabilities
xAI's truth-seeking chatbot with real-time X/web access and extended reasoning
Grok is an AI chatbot from xAI (Elon Musk) with real-time access to X and the open web, a 1M-token context window, and an optional "Think" reasoning mode. The free tier allows roughly 10 prompts every 2 hours; paid plans start at $10/month (SuperGrok Lite). Best for users who need up-to-the-minute information and are already in the X ecosystem.
Grok is an AI chatbot built by xAI, Elon Musk’s AI company, and released in stages from late 2023 onward. Unlike most large-language-model chatbots that rely solely on a static training cut-off, Grok maintains a live connection to X (formerly Twitter) and the broader web, making it able to answer questions about current events, trending topics, and breaking news in real time. The model underlying the product — Grok 4 and its variants — supports a context window of up to 1 million tokens on most plans and up to 2 million tokens on SuperGrok Heavy.
The chatbot ships with a “Think” mode that enables extended chain-of-thought reasoning before delivering an answer, comparable to the approach used in OpenAI’s o-series models. This mode is available on paid plans and measurably improves accuracy on math, coding, and multi-step logic tasks. Grok also includes Grok Imagine, a multimodal image and short-video generation tool (6-second audiovisual clips) that became available starting with SuperGrok Lite. As of May 2026, xAI added Grok Skills (persistent workflow instructions) and Grok Connectors, which integrate third-party services — Vercel, Canva, Gamma, and S&P Global — directly into chat sessions.
Grok is most useful for people who need AI assistance that is grounded in real-time data rather than a months-old training snapshot. It is also positioned as a lighter-censorship alternative for users who find other chatbots overly restrictive on edgy or politically sensitive topics.

Yes. Grok has a standalone product at grok.com that does not require an X account. However, some features — such as X-specific data feeds and purchasing through X — are tied to X platform accounts.
