3. ChatGPT / Claude — Best for Drafting

For solo attorneys and small firms who can't justify enterprise pricing, ChatGPT and Claude are powerful tools for drafting demand letters, contracts, memos, and client communications.

Always verify any case citations (AI can hallucinate)

Use for drafting, not for final legal research

Claude handles long documents better than ChatGPT

4. Perplexity AI — Best for Quick Legal Research

Perplexity searches the web in real-time and cites sources. Useful for getting quick overviews of legal concepts, recent regulatory changes, or jurisdiction-specific rules.

5. Otter.ai — Best for Client Meetings

Transcribe client consultations automatically. Otter.ai creates searchable transcripts and summaries of every meeting.

**Pricing:** Free / $17/month

Legal AI Risks and Ethics

AI in law comes with important caveats:

**Hallucinations** — AI can fabricate case citations. Always verify.

**Confidentiality** — Avoid inputting privileged client information into consumer AI tools.

**Competence duties** — Most bar associations now require understanding of AI tools you use.

**Unauthorized practice** — AI cannot substitute for attorney judgment.

The Bottom Line

Legal AI is no longer optional. Firms that don't adopt these tools will fall behind on efficiency and pricing. Start with ChatGPT/Claude for drafting, add CaseText for research, and scale to Harvey AI as your firm grows.
