What is ChatGPT?
ChatGPT is OpenAI's AI assistant, available on the web, desktop, iOS and Android. It answers questions, drafts and edits text, analyses uploaded files, creates images, holds voice conversations, runs multi-step "deep research" reports and helps with code through Codex.

- Integrations on Business connect Google Workspace, Slack, GitHub and Microsoft 365.
Limitations
- Usage limits on Free and lower tiers can interrupt longer sessions.
- The plan line-up changes often, so older guides quickly go out of date.
- Like every AI assistant, it can state wrong facts confidently — check important answers.
