AI legal assistants have moved from niche experiment to mainstream necessity—but picking the wrong one can lock you into expensive long-term contracts or leave you with unusable templates. Spend 20 minutes answering these questions before you sign anything.
Does it actually understand your practice area?
A tool that excels at residential lease drafting might be useless for corporate M&A work. Most AI legal assistants train on publicly available legal documents, which means they'll handle common, straightforward tasks well but may struggle with specialized niches.
Ask the vendor directly: What training data powers the model? How recent is it? Some tools update quarterly; others run on datasets from three years ago. Real estate agents need current local code references. Employment lawyers need updated statutory language reflecting recent EEOC guidance.
Request a test case relevant to your work. If you handle franchise agreements, ask them to draft one. If you focus on nonprofit formation, request formation documents. The demo should reflect your actual workload, not their easiest use case.
What's the actual cost structure?
Pricing ranges wildly—from $30/month flat-rate subscriptions to $500+ monthly for enterprise accounts. But the sticker price isn't what matters. You need to know:
- Per-document fees: Some charge by the page or by the number of drafts generated per month
- Included usage limits: A tool might advertise $99/month but cap you at five documents per month
- Add-on costs: Premium features, priority support, custom integrations, or API access often cost extra
- Setup and onboarding: Enterprise tools often require consultation time you'll pay for
- Annual prepayment discounts: Committing upfront can save 15–25%, but locks you in
Calculate your realistic volume. If you draft 15 contracts monthly, a per-document fee model will cost more than a flat subscription—but only if that subscription actually covers 15 documents.
How much human review and editing does it actually require?
This is the real productivity question. An AI assistant that outputs 80% usable drafts saves you meaningful time. One that requires rewriting half the document doesn't.
Specific things to test:
- Does it require manual formatting cleanup, or does output come publication-ready?
- How much hallucination occurs? (Lawyers call this "confabulation"—when the AI invents case citations, statute numbers, or legal precedents that don't exist.)
- Does it catch inconsistencies in variable names, dates, or party definitions?
- Can you see its reasoning, or is it a black box?
Run five full drafting workflows during your trial period. Time yourself. Subtract the setup time, then compare against your current drafting speed. If it's not saving you at least 30% on routine documents, it's not worth the monthly cost.
What are the liability and confidentiality guarantees?
This matters far more for legal work than other industries. Before uploading anything:
- Data retention: Does the vendor store your documents after you close them? For how long?
- Third-party sharing: Will your content train the vendor's models or feed into competing users' suggestions?
- Malpractice insurance: If the AI outputs something wrong and you don't catch it, who's liable—you or them? (Spoiler: it's you, but some vendors provide indemnification clauses.)
- SOC 2 compliance: For handling sensitive client information, verify the vendor maintains SOC 2 Type II certification
- State-specific restrictions: Some state bars have ethics opinions limiting AI use; check yours before committing
Request the actual data processing agreement and security audit. Don't accept vague promises.
Can you integrate it into your existing workflow?
The best tool is one your team actually uses. Evaluate:
- Does it connect to your practice management software (Clio, LexisNexis, NetDocuments)?
- Can it import client intake data automatically?
- Does it offer a browser extension, desktop app, or web-only interface?
- Is there an API for custom workflows?
Tools like Mercoly help you compare AI Legal Assistants & Drafting Tools from multiple vendors side-by-side, so you can see integration capabilities across options before deciding.
Friction matters. If your team has to copy-paste content between systems, adoption drops 40%.
Does it offer real trial access?
Free trials that limit you to simple documents or restrict functionality aren't real trials. Demand:
- Full feature access for 14–30 days
- No credit card required upfront
- Ability to test with realistic client scenarios
- Support contact for technical questions during trial
Frequently Asked Questions
Q: Can I rely on an AI legal assistant's citations and case references? No—always independently verify every citation, statute number, and case reference before using the output. AI tools frequently generate plausible-sounding but incorrect legal authorities, and this is entirely your responsibility as the practicing attorney to catch.
Q: Will my state bar allow me to use an AI legal assistant? Most state ethics rules require attorney competence and supervision of the drafting process, but don't ban AI tools; however, some states have issued specific guidance restricting certain use cases, so check your state bar's formal opinions and ethics hotline before adopting any tool.
Q: What should I test during a free trial to know if it's worth buying? Draft three documents you've actually written before—run the AI tool on the same fact pattern and compare output quality, time savings, and the amount of revision needed against your original work.
