FAQ
What is the best AI assistant for a small business?
For an owner who wants jobs done (emails answered, meetings booked, calls made, errands run), Something Big Agent: you text or email it a job and it does the work on its own computer, in your inbox and calendar. It is free to try with no card and paid plans start at $99 a month. If you only want AI inside Gmail or Outlook, Gemini in Google Workspace or Microsoft 365 Copilot is the natural add-on.
How is an AI assistant different from ChatGPT?
ChatGPT answers and drafts in a chat window; you still do the work. Something Big Agent has its own computer, email address and web browser, works in your connected inbox and calendar, and does the job, then writes back to tell you.
How long does it take to set up Something Big Agent?
About a minute. Sign up at somethingbig.ai/agent with your email and mobile number; your assistant gets its own name and email address and you can text it right away. Connect Gmail or Outlook and your calendar with one button each.
How much does Something Big Agent cost?
It is free to try with no card needed. Paid plans for more work each month start at $99 a month.
Is an AI assistant safe for business email?
Check what each tool can do in your account before you connect it. Something Big Agent works in your inbox only once you connect it, and it buys things only when you say yes. Any AI can make mistakes, so check important replies, especially at first.
