ChatGPT is OpenAI’s general-purpose assistant: it writes, researches, makes images and talks, and with connectors and scheduled tasks it can read your accounts and run a prompt on a timetable. Drift is narrower on purpose. It is one agent shaped around your email, calendar and tasks, and it stops for your approval before anything reaches another person.
Where ChatGPT is genuinely better. Breadth. ChatGPT is a general assistant for almost anything, with a large ecosystem around it and a free plan that does a great deal. If what you want is one assistant for every kind of question, and your inbox and calendar are a small part of that, ChatGPT is the more general tool.
Where Drift differs. Built around your own accounts, with the rule written down. Drift publishes exactly which actions stop for confirmation and enforces it in the runtime. It keeps a searchable archive of twelve months of your mail and calendar, connects your own MCP servers, and hands off longer work, like a document, a deck or a coding project, as a job that comes back finished. Its routines run as often as every five minutes and can start from an email or a webhook. You can text the same agent over iMessage on every plan, and Agent Loops keep a standing watch on your calendar, the commitments you make in email, and the prep before your meetings; they suggest, and anything that would act still asks you first.
What it is — Drift: A personal agent for Gmail, Google Calendar, Google Tasks, and Notion. ChatGPT: A general-purpose AI assistant from OpenAI, with connectors and scheduled tasks.
Acts on your email — Drift: Yes: reads, searches twelve months of history, drafts, and sends after you approve. ChatGPT: Yes. The Gmail connector reads and searches your mail, and guides report that paid plans can send from the chat.
Asks before sending email — Drift: Yes. The card shows every recipient and the full body before it sends. ChatGPT: Partly. Guides report that it shows a draft and asks before sending by default, but that is not a published guarantee.
Rebuilds your calendar automatically — Drift: No. Drift books and moves events you ask it to. It has no auto-scheduling engine. ChatGPT: No auto-scheduling engine; scheduled tasks run a prompt at a time you set.
How you drive it — Drift: Plain language. There is no syntax and no board to maintain. ChatGPT: Plain language.
Setup before it is useful — Drift: Connect an account and ask a question. ChatGPT: Light: sign in, and connect accounts when you want it to read them.
Price — Drift: Free forever tier. Flow $8/month, or $6.40/month billed yearly; Horizon $60/month, or $48/month billed yearly. ChatGPT: Free plan. As of November 2026, Go is $8 a month in the US, Plus is $20 a month, and Pro starts at $100 a month.
