Can AI replace Harvey?

You can absolutely build a local RAG assistant over your own PDFs in an afternoon, and for reading your lease or a vendor contract that is genuinely enough. Harvey is not sold on that loop. It is sold on trained-and-evaluated legal workflows, curated case law and regulatory sources under license, deployment that survives a law firm's security review, and the ability to put a name behind an output that a partner will bill against. The thing you cannot one-shot is the confidence to rely on the answer, which in legal work is the entire product. A personal replacement is fine for personal stakes and dangerous the moment money or a filing depends on it.

02Could AI build it for you?

The core job: Indexes a folder of your own contracts and PDFs locally, then answers questions about them with quotes and page citations so you can check every claim yourself.

What a working version needs:

  • An LLM API key, or a local model via Ollama if you would rather nothing leaves the machine
  • Your own documents: no licensed case law, no statute databases, no primary sources
  • Python 3.11 and a willingness to read the cited passage rather than trust the summary

The retrieval half is a weekend, the reliance half is not. The moat is licensed primary law plus an enterprise security posture that took years to clear, and a name a partner can put in a risk memo.

03What you'd give up

  • Licensed primary law: case law, statutes, filings and regulatory corpora you cannot legally scrape together
  • Workflow products that have been evaluated by actual lawyers: diligence checklists, redline review, deposition prep
  • Firm-grade deployment: SSO, data residency, retention controls, audit logs, security questionnaires answered
  • Anyone to blame. Your hallucination is your malpractice exposure
  • Integration into the systems legal work actually lives in: DMS, iManage, Word, the review platform

A law firm is not paying for text generation, it is paying for defensibility. The output has to be traceable to a licensed source, the deployment has to pass a security review that takes months, the workflows have to have been tested against how associates actually do diligence, and there has to be a vendor contract with indemnities when something goes wrong. Individual lawyers also cannot use a homemade tool on client matters without answering awkward questions about where the privileged data went. A local RAG box over your own files solves none of that and does not need to; it solves reading your own documents faster, which is a different and much smaller job.
