The short version
All three are capable general-purpose assistants with free plans. For most people, the deciding factors are where you already work and how you want to reuse instructions, not which model wins a benchmark this month.
- If your business runs on Google Workspace, Gemini’s paid plans bring the assistant into Gmail and Docs.
- If you rely on saved, reusable setups, compare ChatGPT’s Projects and custom GPTs, Claude’s Projects and Gemini’s Gems against how you work.
- If you are rolling it out to a team, compare the business plans’ admin controls and data terms in detail.
How to choose
Run the same three to five real tasks in each free plan — for example, rewriting a customer email, summarizing a long document and drafting a proposal outline. Score the results using our evaluation checklist. Quality differences on your tasks matter more than general rankings.
Then check the details that the free plan doesn’t show: usage limits on the paid tier you’d need, admin controls, and how each provider handles your data.

That’s one more reason this page sticks to facts published on the providers’ own websites and does not rank output quality. Where a detail was not verified for this comparison, the table says so.
