**Harvey AI costs $1,200+/seat/month

Harvey AI costs $1,200+/seat/month. ChatGPT costs $20. That's a 60x price difference — and for most lawyers, ChatGPT with good prompts gets you 80% of the way there. Harvey wins on enterprise security, legal-specific training, firm document integration, and custom Agent Builder workflows. ChatGPT wins on everything else: price, versatility, speed to deploy, and the ability to start using it today without a sales call.

This isn't a close comparison for most firms. Harvey is built for BigLaw. ChatGPT is built for everyone. Here's exactly when each one makes sense.

Price and Access: The 60x Gap

The numbers tell the story:

- Harvey AI: ~$1,200-2,000+/seat/month, enterprise contracts only, annual commitment, minimum seat requirements, sales process required - ChatGPT Plus: $20/month, sign up in 2 minutes, cancel anytime - ChatGPT Team: $25/user/month, admin controls, workspace features, cancel anytime

A 50-lawyer firm deploying Harvey spends roughly $900,000-1,200,000 per year. The same firm on ChatGPT Team spends $15,000 per year. That's $885,000+ in annual savings. Even if ChatGPT is only 60-70% as effective as Harvey for legal tasks, the ROI math favors ChatGPT for any firm where that budget gap matters.

Harvey requires a sales process, security review, implementation timeline, and training. ChatGPT requires a credit card and 5 minutes. For firms that want to start using AI today, that accessibility gap matters as much as the price gap.

What Harvey Does That ChatGPT Can't

Harvey's premium buys you capabilities that ChatGPT genuinely doesn't offer:

Firm document integration: Harvey Vault connects to your document management system and lets the AI analyze, reference, and build on your firm's own work product. Ask it to draft a motion in the style of your top litigation partner, using precedent from your firm's previous cases. ChatGPT can't access your DMS.

Agent Builder: Create custom multi-step AI workflows without code. Build an agent that pulls relevant precedent, drafts initial analysis, flags potential issues, and routes work — all automatically. ChatGPT's Custom GPTs are simpler single-prompt tools by comparison.

Legal-specific training: Harvey is trained on legal data and continuously refined by legal professionals. Its understanding of legal concepts, document structures, and practice-area nuances goes deeper than a general-purpose model.

Enterprise security: SOC 2 Type II certification, data isolation between firms, ethical walls, matter-level access controls. For firms handling sensitive client data, Harvey's security infrastructure is purpose-built. ChatGPT Team has workspace privacy but not the same legal-specific security architecture.

What ChatGPT Does That Harvey Can't (Or Won't)

ChatGPT has real advantages beyond price:

Web search: ChatGPT can search the internet in real-time — find recent case developments, news about opposing parties, regulatory changes, competitive intelligence. Harvey is a closed system focused on your documents and its training data.

Custom GPTs: Build and share reusable legal workflows. A client intake GPT, a discovery response GPT, a contract review GPT — each pre-prompted and ready to go. There's an entire marketplace of legal Custom GPTs built by other lawyers. Harvey's Agent Builder is more powerful but requires enterprise deployment.

Multimodal capabilities: Upload images of handwritten documents, analyze photos from accident scenes, process scanned PDFs. ChatGPT's vision capabilities handle visual legal evidence that text-only tools can't.

Ecosystem breadth: ChatGPT integrates with thousands of apps via Zapier, Make, and its API. Automate document processing, email triage, calendar management, and client communication workflows. Harvey integrates deeply with legal-specific tools but narrowly.

The 80% Rule: When ChatGPT + Good Prompts Is Enough

For 80% of legal AI tasks, ChatGPT Plus with well-crafted prompts matches Harvey's output quality. Drafting motions, summarizing depositions, preparing client communications, analyzing contracts, brainstorming legal strategies, research starting points — ChatGPT handles all of these effectively at $20/month.

The 80% that ChatGPT handles well: - First drafts of any legal document - Contract clause analysis and red-flagging - Deposition summary and key point extraction - Client communication drafting - Legal argument brainstorming and counterargument preparation - Case timeline generation - Discovery response drafting

The 20% where Harvey genuinely outperforms: - Cross-referencing against your firm's own precedent bank - Multi-step automated workflows involving multiple data sources - Institutional knowledge capture and application - Enterprise-grade security and compliance requirements - Firm-wide deployment with centralized governance

If your practice lives in that 20%, Harvey is worth the premium. If it doesn't, you're paying 60x for capabilities you won't use.

The Verdict: Who Should Buy What

Choose Harvey if: You're an Am Law 100 firm with 200+ lawyers, billing rates above $600/hour, complex transactional or litigation practices, a significant precedent bank worth integrating, and the budget to commit $1M+/year to AI. Harvey's ROI is real at this scale — even small efficiency gains across hundreds of lawyers generate massive returns.

Choose ChatGPT if: You're a firm under 100 lawyers, a solo practitioner, in-house counsel, or any legal professional who wants AI assistance today without a six-month procurement process. Start with ChatGPT Plus ($20/mo), build Custom GPTs for your common workflows, and pair it with Claude Pro ($20/mo) for drafting. Total: $40/month.

The hybrid approach: Some forward-thinking midsize firms are using ChatGPT Team for all lawyers ($25/user/month for daily AI assistance) while evaluating whether Harvey's premium tier makes sense for specific practice groups. This lets every lawyer benefit from AI now while gathering data on whether the 60x price jump would deliver proportional value.

The Bottom Line: ChatGPT at $20/month is the right choice for 90% of lawyers. It handles drafting, analysis, research, and client communication effectively with good prompts. Harvey at $1,200+/month is justified only for Am Law 100 firms with high billing rates, deep precedent banks, and complex workflows that require enterprise integration. For everyone else, the 60x price premium buys capabilities most practices won't use.
