The legal first-pass stack

Two of the three tools have a free tier to start; Adobe Acrobat AI Assistant is paid from day one. The 03 COSTS table above breaks down each tool's pricing. Two meters climb with use: Claude's message and generation caps, and NotebookLM's daily generation limits; each upgrade buys higher ceilings, not new members. Watch whichever tool you lean on daily, since that is the meter that bites first. And keep the real expense in view: the lawyer sits outside this stack, and the stack's job is shortening that step.

No. Claude alone covers first-pass review and plain-English clause explanation, which is most of the triage, and many run on it for weeks. The numbered steps double as the adoption order: add NotebookLM once questions start spanning several contracts and policies and answers need passage-level citations, and Acrobat's assistant when agreements keep arriving as PDF attachments. None of it replaces counsel.

Claude already carries the open reasoning: first-pass review, clause explanation and drafting help on whatever lands in front of you. You can defer the rest until volume demands it. What this stack adds is discipline against the record: NotebookLM answers strictly from the contracts and policies you load, with citations that jump to the passage, and Acrobat's assistant questions the PDF inside the reader it arrived in.

NotebookLM and Acrobat's AI Assistant both do document Q&A with citations, the one real overlap here. The dividing rule is scope. Acrobat owns the single agreement that just arrived as an attachment, questioned inside the reader it came in. NotebookLM owns the assembled corpus: many contracts and policies where an answer needs to cite across the whole set. The Acrobat AI and NotebookLM comparison, linked above, covers the finer calls.

When first-pass triage stops being the job. Two signals mark the line: you are redlining and negotiating contracts often enough that you need clause libraries and tracked positions rather than a fresh read each time, and the agreements carry enough risk that a defensible, contract-specific tool beats general assistants. Both point to the competitive tier, the professional contract stack.

Treat privileged contracts as a configuration question. Claude sets the floor: its personal plans may train on what you type unless you turn that off, and only the Team and Enterprise tiers exclude training, so signed or confidential material belongs there. NotebookLM's uploads sit on Google servers, so check your Workspace terms first. Keep every account under organisational control, not a personal login.
