Why In-House Teams Need Purpose-Built Legal AI

Harvey was first built for law firms and bills itself as Professional Class AI. GC AI was built by a General Counsel, for General Counsels.

What is GC AI?

Legal AI built exclusively for in-house counsel

GC AI connects your company's contracts, policies, and data sources with modern LLMs, so every answer aligns with how your business and legal team actually operate.

Harvey: First built for law firms, now expanding into in-house. Strong on matter-based, high-volume firm workflows.

Why does specialization matter?

Your outputs go to the business, not to a partner

In-house work ends up in front of executives, finance teams, and boards. GC AI answers are written to be pasted into Slack or a board deck, not handed back to another lawyer.

Harvey: Defaults to the thorough, law-firm-style analysis a partner expects from an associate. The right fit if your audience is always legal.

What can GC AI do that Harvey can't?

Character-level citations and CLE-certified training

Exact Quote cites documents at the character level, and 6,000+ lawyers have been taught through CLE-certified (California) courses led by former general counsels.

Harvey: No published character-level citation. Harvey Academy and an academic program with law schools, but no CLE-certified practitioner training.

GC AI for Word redlining a contract inside Microsoft Word

Easy Prompt, the Skill Library, and a Word Add-In Built for Your Workflow

Easy Prompt rewrites your plain language into the kind of structured prompt that gets the best answer from the model. No prompt engineering required. The In-House Skill Library ships with pre-built workflows for MSAs, DPAs, privacy matters, board resolutions, and employment agreements.

The Word Add-In is available on Microsoft AppSource and handles redlining, issue spotting, drafting, and comment summarization inside Word.

The Output Reads Like Advice from a Colleague, Not a Memo from Outside Counsel

Drop the response into Slack. Paste it into a board deck. Send it to your CMO. GC AI writes for the people you share your work with -- and most of them are not lawyers.

Harvey defaults to the thorough, detailed analysis a law firm partner expects from an associate. GC AI optimizes for business-ready communication. If your audience is a senior partner, Harvey's depth works. If your work goes to the CEO on Thursday, GC AI was built for that.

Your Data Is Private and Encrypted

GC AI maintains zero data retention agreements with OpenAI and Anthropic, meaning your prompts and documents are never stored by model providers or used for training. GC AI is also SOC 2 Type II and SOC 3 certified, GDPR compliant, and AES-256 encrypted. Harvey holds SOC 2 Type II, ISO 27001, GDPR, and CCPA compliance.

This is the number one question in every class and every sales conversation. The answer is straightforward, and your security team can verify all of it directly at trust.gc.ai.

What in-house teams say about GC AI

Katelyn Canning's company logo
The GC AI Word plugin has transformed my legal workflow, allowing me to draft and review documents in a fraction of the time it used to take. What used to be hours of tedious contract review now takes minutes, with the AI instantly flagging potential issues and suggesting precise language improvements that align with our company standards and preferences. The seamless integration with Word means I can leverage powerful legal AI without disrupting my existing workflow, making it an indispensable tool for our legal team.

GC AI's Word Add-in is in a class of its own compared to other legal AI tools I have evaluated. Its ability to produce a first-pass redline of an agreement against our own templates has significantly reduced the time required to review non-standard contracts. Furthermore, GC AI's capacity to suggest market-standard compromises and provide clear, concise explanations for edits accelerates negotiations and fosters a more collaborative process between parties.

GC AI for Word has become an integral part of my workflow. Its integration into the online portal ensures seamless communication between the two platforms and helps ensure we're communicating with all stakeholders accurately and efficiently. Most importantly, I appreciate that GC AI continues to listen to their users and improves the software continuously.

Today's victory: my board chair asked me a long time ago for an index of all board resolutions. I can only use the word “collaborate” to describe how I first worked out with GC AI how we were going to do this. I was also mindful of the possibility that GC AI might not be able to remember all of the content since I had about 50 PDF docs to summarize and put into a table. We first worked out what the table would look like, then I uploaded each one and it produced the output in table format for that one doc. And asked me for the next doc. After I uploaded about 10 docs one by one, I asked it to consolidate all the entries into a single table and put it in reverse chron order. It did. I praised it and then fed the rest of the docs one by one. At the end, it produced a consolidated table without any problem. And it asked me if I wanted it to do any more analysis on the data. I'm honestly stunned at how well this worked out. And I also feel like maybe GC AI is turning the tables by giving me positive reinforcement for the approach. That's fine. I welcome the robot army if they will do tasks like this.

As a fractional general counsel for two fast growing technology companies, GC AI for Word has transformed how I handle legal document review and drafting. The integration is seamless, the AI suggestions are remarkably accurate for legal context, and it saves me hours each week. The beta testing experience showed a team that truly listens to user feedback. This tool understands legal nuance in ways other AI tools simply don't. Highly recommended for any legal professional working in Word.
Mike BittnerMike BittnerGeneral Counsel
The GC AI for Word plugin has gone from a curiosity to an essential component of my workflow for contract reviews. The product team has been very responsive as we've identified new issues and proactive about adding new capabilities. It doesn't replace the need to think critically about every redline, but it cuts down dramatically on the time you need to spend on the easy stuff so you can focus on the issues that truly need your attention.

GC AI for Word is an invaluable multi-purpose legal assistant. It streamlines document management by identifying missing or duplicated clauses while also handling complex document review with precision. The tool excels at flagging potential regulatory issues and enforcement risks, then provides targeted language to mitigate these concerns. As a legal professional, I rely on this tool daily for efficient document drafting and comprehensive review processes.
