ChatGPT, Claude or Gemini: how should you choose?
Compare the tools on a task you actually do. Look at how much correction they need, whether you can check the sources and what your account is allowed to handle.
Give them the same task
Choose a public two-page document and ask each tool for a short summary with three factual claims and where each appears in the document. Use the same file and instructions. If an account lacks a feature you need, record that as part of the comparison.
Measure the whole job
Time the process from opening the tool to having a usable summary. Include source checking and corrections. A quick answer can take more time overall if you need to trace every number yourself. If two tools perform equally well, access, workplace approval and cost can decide.
Add one difficult test case
Also test a file with a table and a qualification in a footnote. Check whether the model preserves it. Record the service, feature and date you tested so you can compare again as the tools change.
