Most teams pick an AI model from a benchmark table, then find out it behaves differently on the documents they actually work with.
The faster check is to take one real file from your own work and give Gemini and Claude the same instruction. What matters is not which model wins, but where the two answers split. One may follow your formatting; the other may add missing context you did not ask for. Those gaps tell you which model fits this task.

Try the same comparison on a second file type before deciding. A contract, a spreadsheet export, and a design brief will not produce the same split, so one test is not enough. Keep a short note of which model you used, which file type you tested, and which difference mattered. Two or three notes beat a benchmark chart you cannot reproduce.

Use the extension when you want the same questions sent to several models at once instead of retyping them, then record what came back.
