ChatGPT is a destination. You open the app or a tab, ask for anything (research, images, code, a draft), and bring the answer back yourself. The free plan includes unlimited text chats. That breadth is the point.
Grais sits somewhere else. It is a browser extension for Chrome, Brave, Edge and Arc that drafts the reply inside the WhatsApp Web, Telegram Web, Instagram, LinkedIn or Tinder conversation you already have open, using what it remembers about that person.
Pick ChatGPT when you want one assistant across many kinds of work, on every device, with a free tier. Pick Grais when the work is the reply itself: the open thread, the relationship, and what you already promised that person.
Grais is invitation only for now. New accounts need approval.
