Strengths and weaknesses
ChatGPT
- Widest feature set of any AI assistant
- Polished apps on phone, desktop and web
- Free plan runs on the latest model family
- Free and Go plans show ads in some countries
- Chats train models by default unless you turn it off
- Top models and higher limits require a paid plan
ChatGPT is the most complete AI assistant you can get. It writes, codes, searches the web, talks back in voice mode, makes images and can work through long tasks with its ChatGPT Work agent. GPT-6 now powers every plan, and memory and projects keep context across chats. The catch: the Free and Go plans show ads in several countries, and your chats train models unless you opt out.

Grok
- Up-to-the-minute answers on news and trends
- Strong reasoning models on paid plans
- Image and video generation for subscribers
- Deepfake scandal led to probes in several countries
- Closely tied to X and its data practices
- Best models and Grok Imagine require a subscription
Grok stands out for real-time knowledge pulled from X, so it is quick on breaking news and trending topics. Paid plans add Grok 4.7 in Expert and Heavy modes, plus Grok Imagine for images and video. It is looser with content limits than most rivals, and that backfired in January 2026, when sexualized deepfakes made with Grok triggered investigations in the EU, UK and beyond. Privacy and safety remain the weak spots.
