Key takeaways
  • A $20 general AI covers most solo needs.
  • Dedicated legal tools cost more, for good reasons.
  • Never verify a citation the AI gave you? Don't file it.
  • Check confidentiality rules before pasting client info.
  • Advice and the hard calls stay with you.

The legal-AI market wants you to believe you need a platform with a per-seat enterprise price. If you're a solo attorney, you don't, at least not to start. Most of what would actually save you time this month costs less than a nice dinner out.

Here's the honest breakdown of what's worth paying for under fifty dollars, and just as important, the rules that keep AI from getting you in trouble.

The cheapest high-leverage move: a good general AI

Before any legal-specific tool, the paid tier of a general-purpose AI (ChatGPT or Claude, both around twenty dollars a month at the time of writing) covers a surprising amount of a solo practice's day-to-day:

  • First drafts of client emails, engagement letters, and routine correspondence
  • Summaries of long documents into plain language
  • Turning your notes into a clean, structured memo
  • A starting point for research you then verify against real sources
  • Reworking dense legalese into something a client can actually follow

For most solo attorneys, this single subscription is the best twenty dollars you'll spend, because it touches the writing and summarizing you do every day.

Legal-specific AI tools cost more than a general subscription, and for some work they're worth it. They're trained on case law, they cite to real sources, and the better ones connect to legal databases so the research is grounded rather than guessed.

If your practice leans heavily on research and citation, a legal tool can pay for itself in hours saved. Pricing changes often and varies by tool, so check current rates before you commit, and start with a trial. For a solo just getting going, the general AI plus careful verification often covers you until the volume justifies more.

Two rules that aren't optional

This is where AI gets lawyers in trouble, so read this part twice.

Verify every citation, every time. General AI tools can invent case names and citations that look completely real and do not exist. Attorneys have been sanctioned for filing them. Treat anything an AI hands you as a draft from a bright but unreliable clerk. If you can't pull the actual source and confirm it says what the AI claims, it does not go in a filing.

Check confidentiality before you paste. Your duty of confidentiality doesn't pause because a tool is convenient. Before you put client information into any consumer AI, understand where that data goes and whether it's used for training, and check your jurisdiction's ethics guidance on AI. Plenty of useful work (drafting a template, summarizing a public document, cleaning up your own writing) never requires client-identifying details at all.

Handled with those two rules in place, AI is a genuine help. Ignored, it's a malpractice risk. The tool doesn't know the difference. You do.

What stays with you

AI drafts. It doesn't advise. It doesn't weigh a client's risk tolerance, read a room in a negotiation, or make the strategic call about whether to settle. It hands you a faster first pass on the writing and research so your hours go to the counsel your clients are actually paying for.
