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.

# Harvey indie build

## Goal

Build the smallest trustworthy replacement for the core Harvey workflow for one developer or a tiny team.

## Scope

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.

## Quick start

1. Install the documented dependencies.
2. Copy `.env.example` to `.env`.
3. Run the development command chosen during implementation.
4. Complete the acceptance checks in `BUILD_PLAN.md`.

## Honest limits

This build deliberately does not replace:
- 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

If those capabilities are essential, use Harvey instead of pretending the gap is solved.

why people still pay

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.

Not really. Harvey's value is not the code: 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. See the honest breakdown above.
