CoCounsel costs $300+/month. Harvey AI is enterprise-only with pricing that makes partners wince. If you’re a solo practitioner or a 5-person firm, those numbers are absurd — especially when you’re not sure AI will actually help enough to justify the cost.

Good news: you can get 80% of the benefit for under $50/month. I’ve talked to dozens of small firm lawyers about their AI setups, and the ones getting the most value aren’t using the expensive tools. They’re using smart combinations of affordable ones.

Here are the best options.

1. ChatGPT Plus — $20/month

Best for: Drafting, research starting points, client communication

ChatGPT Plus gives you GPT-4, which is significantly better than the free version for legal work. Use it for:

• First drafts of motions, letters, and emails
• Summarizing long documents (paste text, ask for summary)
• Generating deposition questions
• Writing billing descriptions
• Brainstorming legal arguments

The catch: It fabricates case citations. Never cite a case from ChatGPT without verifying it on Westlaw or LexisNexis.

2. Claude Pro — $20/month

Best for: Long document analysis, nuanced writing

Claude handles longer documents than ChatGPT (up to 200K tokens — roughly 150,000 words). This makes it better for:

• Analyzing entire contracts without splitting them up
• Reviewing lengthy discovery documents
• Drafting longer briefs and memos

Claude also tends to be more cautious and nuanced in its legal analysis, which is a feature, not a bug.

3. Clio Duo — Included with Clio subscription

Best for: Practice management with AI built in

If you already use Clio for practice management, Clio Duo adds AI features:

• Draft emails and documents from within Clio
• Summarize case files
• Generate billing entries
• AI-powered search across your matters

The advantage is integration — you don’t need to copy-paste between tools.

4. Grammarly Business — $15/month

Best for: Polishing legal writing

Not a legal AI tool per se, but invaluable for:

• Catching errors in briefs and correspondence
• Improving clarity and readability
• Maintaining consistent tone across documents
• Checking for passive voice (judges hate passive voice)

5. Otter.ai — $10-17/month

Best for: Meeting and deposition notes

Otter transcribes meetings, client calls, and depositions in real-time. Use it to:

• Transcribe client intake meetings
• Create searchable records of phone conferences
• Generate meeting summaries automatically

Privacy note: Don’t use Otter for privileged conversations without client consent.

The $50/Month Stack

For maximum impact on a budget:

Tool	Cost	Primary Use
ChatGPT Plus	$20	Drafting + research
Grammarly	$15	Writing quality
Otter.ai	$10	Transcription
Total	$45

This stack covers drafting, research, writing quality, and transcription. Add Claude Pro ($20) if you work with long documents frequently.

What You Don’t Need (Yet)

• CoCounsel ($100-200+/mo) — unless you do heavy Westlaw research daily
• Harvey (enterprise pricing) — designed for large firms
• Legal-specific AI platforms ($50-100+/mo) — most replicate what ChatGPT does with a legal UI

The ROI Calculation

If these tools save you 5 hours per month (conservative estimate):

• 5 hours × $300/hour billing rate = $1,500 in recovered billable time
• Tool cost: $45/month
• ROI: 33x

Even if you only save 2 hours per month, the ROI is still 13x. There’s no scenario where $45/month in AI tools doesn’t pay for itself.
