Start with the job you need done
Choose a concrete task: understand a market structure, test a position thesis, or inspect explicitly entered event terms. These are different jobs. A polished answer to an unrelated question is not evidence that a tool supports your workflow. Write down your market, horizon and required inputs before comparing options.
Test traceability with one question
Use a question whose context you can independently inspect. Can the result identify its snapshot time, show supporting and opposing evidence and locate the relevant chart observation or source? Check whether citations support their nearby claims. Do not rank a tool by confident wording or by citation count alone.
Look for honest limits
Try a question with a deliberately missing required input. A useful response should explain the gap, narrow its claim or ask for clarification. Also ask what would invalidate the conclusion. Uncertainty is information; a tool that always produces an action may be hiding the limits of its evidence.
Check privacy, access and practical use
Before sharing data, establish whether a workflow needs private positions or account credentials, which regions are supported, and how accounts and usage limits work. Inspect the contact route and how a service failure is explained. For Biance Vision, access is currently manual, usage is account-limited and there is no public self-service registration or order execution.
Use a comparison you can reproduce
Record the exact question, inputs, timestamps and source checks. Compare whether each tool meets your requirements rather than inventing a universal winner. This page is a requirements checklist, not a competitor benchmark. Explore our public cases and confirm access conditions before deciding whether the workflow fits.
