Pick for the task, then verify the output.
- Start with the task, not the brand — drafting, research, review, diligence or litigation.
- Check confidentiality first. Privileged material needs a tool that runs in your account or locally.
- Open every source the tool cites. Grounding reduces hallucination; it does not remove it.
- Then run the verification pass — the method that makes any output defensible.
No tool is a verification. Whatever you pick, label every claim authority or reasoning — and a named lawyer signs off.
