Best forAll-round writing, questions, brainstorming and everyday help
Free planFree account with unlimited text chats on the GPT-5.6 Luna model, plus web search, file uploads, image generation and voice, which keep their own limits
ChatGPT is the AI assistant that made generative AI mainstream, and it is still the tool most people try first. You type a question or task in plain English and it answers in a conversation, so you can ask follow-up questions, ask it to rewrite something or change the tone.
The free plan covers most everyday needs: drafting emails and posts, summarizing articles, explaining difficult topics, planning trips, writing simple code and searching the web for current information. You can also upload files and photos, create images and talk to it out loud on your phone.
What you can do with ChatGPT for free
- Draft emails, cover letters and social media posts
- Summarize long documents and web pages
- Explain a topic step by step for study
- Brainstorm business, content or gift ideas
Good to know: Unlimited text chat is subject to OpenAI's abuse guardrails, and file uploads, images and other tools still have separate limits. OpenAI is also gradually letting free users try its newer GPT-6 Luna model, so the model menu may differ between accounts. The free plan does not include the top paid models and limits advanced features such as deep research. Free accounts may see sponsored messages below some answers. You can stop your chats being used for training in the data controls settings.
