📜 Table of Contents
A paralegal spends a third of the day on legal research — running the same query, skimming cases, cite checking. AI legal research assistants cut that to a conversation: ask in plain language, get cases with pinpoint cites and a verification chain.
Why paralegals get the biggest win
Associates bill for drafting; paralegals bill for research hours. Tools that compress research time compress the paralegal’s most repetitive work — and the case law is public, so AI answers are checkable.
6 tools from solo firms to Big Law
1. CoCounsel (Casetext, now Thomson Reuters) — the AI legal assistant (enterprise pricing) The most established: review, research, and document analysis in one. Trusted by firms from solo to AmLaw; priced per seat, quote required.
2. Paxton AI — research plus drafting for smaller budgets (~$69/mo) Plain-language queries return cases, statutes, and memos with citations; built for smaller firms and in-house teams.
3. Fastcase — free with many bar memberships (included with bar membership) The classic database now has AI-assisted research; if your state bar includes it, this is the zero-cost starting point.
4. Lexis+ AI — the big-database answer (add-on pricing) AI research on the Lexis corpus with conversational follow-ups; for teams already paying for Lexis.
5. Westlaw AI-Assisted Research — same, on Westlaw (add-on pricing) Conversational research and summary on the Westlaw corpus; pairs with existing Westlaw seats.
6. Harvey — the enterprise name (enterprise pricing) Used by major law firms; deep model training on legal work. Way beyond most paralegal budgets, listed for context.
How to pick
Zero budget: Fastcase via your bar. Small firm: Paxton AI. Already on Lexis or Westlaw: the AI add-ons. Enterprise: CoCounsel or Harvey.
The rule that never changes: verify every AI cite before it reaches a brief.
❓ FAQ
Can I trust AI case citations?
Check every one — hallucinated cites still happen. Verify on the original database before filing.
Do I need a Lexis or Westlaw subscription?
For serious work, yes — the AI tools run on top of these corpora, or rely on Fastcase if your bar covers it.
What about confidentiality?
Enterprise tools have client-confidentiality terms; consumer AI is not appropriate for client data.
