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.

Gamma
- Polished first drafts from a short prompt

- Free credits are a one-time grant that never refreshes
- Free plan caps you at 10 slides per prompt
- Individual plans train on your content unless you opt out
Gamma turns a prompt, an outline or a pasted document into a polished presentation, doc, website or social post in moments. Gamma 5, released in October 2026, lets you talk the idea through with its agent before it builds anything, then fine-tune on a freeform canvas. Exports to PowerPoint, PDF and Google Slides work even on the free plan. Free credits never refresh, though, and free decks carry Gamma branding.
