ChatGPT is a conversational AI assistant developed and provided by OpenAI. Its public release in November 2022 sparked the generative AI boom, and it remains one of the most widely used AI services in the world. Beyond text, it accepts voice and image input, and can help with everyday tasks such as information lookup, summarization, writing, translation, brainstorming, and coding. In addition to the web version, desktop apps for Mac/Windows and mobile apps for iOS/Android are available, with conversation history synced across devices.
Key Features
- Multimodal input: Supports text, voice, and image input. You can show it a photo and ask questions, or talk to it naturally by voice — no keyboard required
- Runs on the GPT-5.6 family (as of August 2026): GPT-5.6 Luna, the conversational model, is available even on the free plan; the stronger reasoning models GPT-5.6 Sol and Terra require Plus or above, and the top-tier GPT-5.6 Sol Pro is Pro-only. Model names and generations turn over quickly, so check the official pricing page before you commit
- Custom assistants with GPTs: Build and share your own assistants specialized for specific tasks without programming. The GPT Store also offers many GPTs published by other users
- Projects for ongoing work: Group related conversations, files, and instructions into a single project, making it easier to organize long-term work or research by topic
- Source-backed reports with Deep Research: Automatically researches across the web and generates detailed reports with citations. Useful for delegating time-consuming research such as market analysis or technology comparisons
- Agent features and coding support: Beyond simple chat, ChatGPT keeps expanding into task delegation — an agent mode that operates a browser on your behalf and coding assistance for developers (Codex)
- Broad platform support: Available on web, Mac, Windows, iOS, and Android. Core features can be tried for free, keeping the barrier to entry low

About ads: OpenAI began testing ads inside ChatGPT in the US on February 9, 2026, and has been expanding coverage in phases. Per the official help center, ads may appear only on the Free and Go plans — Plus, Pro, Business, Enterprise, and Edu do not show ads (nor do accounts identified as belonging to under-18 users). Ads appear below a response, clearly labeled as sponsored, and are stated not to influence the answers themselves. Whether you see them depends on your region and account, so check the official help article for details.
