Purpose

OpenAI’s natural-language AI assistant for questions, writing and material analysis, with available Work mode for files and multi-step tasks.

Features described in official documentation

  • Chat supports questions, brainstorming and text revision; Work carries larger tasks toward a defined output
  • Files, projects, web search and installed plugins can supply context
  • The desktop app organizes projects, previews files and connects browser or other tools, subject to platform and account access

Suggested starting workflow

  • Define a question or reviewable output and add the needed material
  • Choose Chat or Work when available in the current interface
  • Check sources, numbers and produced files, then request focused changes

These are editorial starting suggestions based on the purpose, not a workflow tested by this site.

Before you use it

  • Features depend on plan, platform, region, rollout and workspace settings; Work/desktop descriptions do not certify equal access for every account or web interface
  • Plugins, browser, network and tool actions can depend on administrator settings and authorization; no sign-in or actual tool use was tested
  • Selected plan facts and account, usage and billing boundaries are listed below. Unknown prices are not inferred; regions, commercial use and full task outcomes still require review. No sign-in or model task was performed in this batch.

Pricing & plans

Selected plan facts only, not a complete plan review or a task test. Check the source date and confirm current terms with the provider. Unverified conditions remain unknown.

Complete review Every listed plan of this tool has a complete review. Complete review: price, currency, billing period, platforms, languages, regions, watermark, commercial use and offline use each have a source or a stated reason they could not be confirmed. It is not a task test and does not guarantee current prices.
