Who this is for
People choosing between OpenAI's and Google's 24/7 personal agents, usually deciding whether their work lives in Slack and many apps or in Gmail, Drive and Calendar.
Side by side
| Compared on | ChatGPT dots | Gemini Spark |
|---|---|---|
| What it is for | One always-on agent that owns ongoing goals across many connected apps. | A personal agent for tasks, schedules and skills across Google apps. |
| Starting price (checked 2026-10-09) | From $100/month (ChatGPT Pro); also in Business Premium. | $19.99/month (Google AI Pro, US); Ultra from $99.99/month. |
| Accounts it works with | Personal Pro and Business Premium; Enterprise beta when the admin turns it on. | Personal Google Accounts only; no work or school accounts yet. |
| Limits | Plan allowance for deeper work; Codex and Work tasks count toward usage limits. | Shares Gemini's compute-based usage limits; up to 15 tasks at once. |
| Where it breaks | Reads connected apps proactively; disconnecting does not delete what it took. | Experimental; uses sites you are signed into; Keep Activity must be on. |
| Setup | No-code; create it on desktop. | No-code; switch to Spark in the Gemini app or web. |
| A custom build beats it when | One fixed workflow runs on a schedule. | A fixed Gmail or Sheets rule that Apps Script can run. |
The verdict
Both are 24/7 agents that work in the cloud while your devices are off and check with you before major actions, and neither is available on personal plans in the EEA, Switzerland or the UK. Gemini Spark is far cheaper to try, included in Google AI Pro at $19.99 a month in the US, and is built around Gmail, Drive, Docs and Calendar, but it works only with personal Google Accounts and runs at most 15 tasks at once. A dot needs ChatGPT Pro from $100 a month or Business Premium, connects to 4,000+ apps plus Slack and Teams, and has a business plan route.
Pick Spark if your life is in a personal Google account; pick a dot if your team works in Slack or Teams and you already pay for Pro.
