Who it's for

  • Anyone new to AI. It handles questions, writing, translation, summaries, code, and images in one place, making it the default choice when unsure what to pick.
  • Professionals who need to quickly draft reports and emails, organize uploaded files, and generate images when needed.
  • Anyone who wants to practice English conversation or brainstorm on their phone using voice. Voice mode understands Korean naturally.

Drawbacks

  • The free plan has hourly usage limits for the latest model, so it may switch to a slower model or require a wait during heavy use.
  • It can confidently provide plausible yet incorrect answers (hallucinations), so numbers, dates, and sources must be double-checked.
  • Image generation and file uploads have low daily limits on the free plan.

Getting started

  1. Open the official website to start asking questions right away without logging in. Sign up with a Google or Apple account to save conversations.
  2. Type what you want done with context in the input box. Example: "Politely write a field trip notice for elementary school parents."
  3. If you don't like the answer, ask for quick adjustments like "shorter", "in a table", or "more formal".
  4. Upload PDFs, images, or Excel files via the paperclip icon to analyze them. Ask it to "draw a picture" to generate images.
  5. Save frequent instructions in "Custom instructions" to avoid repeating them. Install the mobile app to use voice mode.
