Harvey is an AI assistant built on large language models. It helps lawyers with research, drafting, document review, and legal analysis. Think of it as a very intelligent co-pilot that sits beside you while you work. Harvey’s core value proposition is AI-generated text — it produces answers, summaries, clauses, and analysis on demand.

Harvey is exceptional at what it does. It can read a 200-page agreement and summarise the key terms in seconds. It can draft a first pass of an indemnification clause tailored to your jurisdiction. It can review a contract and flag potential issues. It raised over $100 million in funding for good reason — lawyers need intelligent drafting assistance, and Harvey delivers it.

Pactum is not an AI assistant. It is a contract editor. Specifically, it is the first contract editor built entirely on HTML — a format that is structured, searchable, machine-readable, and browser-native.

Where Harvey helps you write the contract, Pactum changes what the contract is. When a contract is drafted or imported into Pactum, every clause is tagged with its type, every obligation is extracted automatically, every deadline is tracked, and the document becomes something AI can actually read and reason about.

Pactum also provides multiple standard clauses with AI guidance, playbook alignment (automatic company standard verification), real-time collaboration, e-signature, legacy PDF/.docx conversion, semantic redlining, and client-side processing where your files never leave your browser.

This is not a subtle distinction. It is the difference between a tool that helps you write in Word and a tool that replaces Word entirely.

The legal industry has a format problem disguised as an AI problem. Harvey can write a brilliant contract — and then that contract gets saved as a .docx file, emailed to the counterparty, signed as a PDF, and dropped into a shared drive where no system on earth can search it, track its deadlines, or extract its obligations.

The AI that drafted the contract cannot read the contract it drafted. That’s the gap Pactum fills.

The most powerful legal workflow is not Harvey or Pactum. It’s Harvey and Pactum together:

1. Use Harvey to research, analyse, and generate clause language.
2. Paste that language into Pactum’s HTML editor.
3. Pactum tags every obligation, checks it against your playbook, and makes the entire contract machine-readable.
4. Collaborate with your team in real time. Sign without leaving the platform.
5. The signed contract stays in HTML — searchable, trackable, alive — on your cloud.

Harvey makes you a better drafter. Pactum makes sure what you draft doesn’t die the moment it’s signed.

You need AI-powered legal research, document summarisation, or on-demand clause generation. You want a co-pilot for thinking through legal problems. You are comfortable with your contracts staying in traditional formats (.docx, PDF).

You need your contracts to be machine-readable, searchable, and trackable after signing. You want obligation detection, playbook alignment, and real-time collaboration in one editor. You require client-side processing and zero data retention. You have legacy contracts that need converting from dead formats to living HTML.

You want the best of both worlds — AI-powered drafting assistance from Harvey, poured into contract infrastructure from Pactum. This is the stack that forward-thinking legal teams will adopt.
