01
Purpose-built legal tools
Tuned and grounded tools for defined legal tasks — clause review against a fallback position, precedent retrieval with verified citations, and ROPA drafting — best when the work is playbook-bound, repeatable, and needs auditability and a defensible review trail.
02
General-purpose foundation models
Open-ended models for exploration and synthesis — issue spotting on novel fact patterns, first-draft framing, and plain-language explanations — best when the task is judgment-heavy, non-repeating, and a human attorney will review and rework the output before it leaves the team.
03
Citation & grounding
Specialized tools ground answers in a controlled corpus with source links a reviewer can open; general models generate fluent text that can hallucinate citations — so treat any unverified citation from a general model as untrustworthy until checked against the primary source.
04
Confidentiality & data scope
Defines which engine may see what: specialized legal tools with enterprise data isolation for matter-bound work versus de-identified or redacted prompts to general models for anything touching client confidences, with a firm-approved list rather than attorney-by-attorney choice.
05
Review & approval workflow
Specialized tools slot into existing review steps with built-in redlining and sign-off; general models produce a draft that must enter the standard review queue — so the workflow, not the model, controls what reaches a counterparty or the file.
06
Decision & routing guide
Gives the team a one-page rule: task type, confidentiality tier, and audit requirement together pick the engine, so 'which AI do I use here?' has a documented answer instead of a guess.
