Your document. Your agent. One workspace.
Easy to start, with every drafting tool already in place. Brief it like an associate: it writes the whole document, then edits it as tracked changes you review clause by clause.
Two modes. One rule: nothing changes without a trail.
Works on the document.
Give an instruction and Corpus creates the document, or lands its edits as pending Word tracked changes for you to accept or reject. It reads the matter's references first, and it cannot overwrite your text without a trail.
Answers about the document.
Ask what a clause means, what is missing, or how a term is defined. Corpus answers in the panel and the document is untouched, guaranteed by the system rather than by a promise in a prompt.
No more (deleted: copy, paste, reformat).
Just the finished document.
The deliverable, not a reply. You get the Word file you send, with numbering, defined terms and blanks for your deal details.
Every edit is tracked. Corpus never silently overwrites a clause. You review its work like a colleague’s.
Easy from the first matter. Drafting, review, research and versions in one place. Nothing to set up, nothing to learn.
Redline any two versions.
Import the other side’s markup, pick two versions, and see every difference as a proper redline. Try it below.
Every version is kept. Every difference is visible. Nothing changes without a trail.
Everything a drafting lawyer reaches for.
- Contract review, start to finish
- Corpus reads the whole document before it touches it, publishes an issue list, works every item, and closes with what it addressed and what it deferred to you.
- Point it at anything
- Type @ to bring in a draft, a reference file, a section of law or a Brief thread. Long pastes collapse into tidy context chips.
- Native Word, kept native
- Auto-numbering, nested tables, defined terms and fields survive every edit. What you download is a real .docx, not a conversion.
- Every version kept
- Each AI draft, import and accepted state is saved. Open any of them, or compare two as a redline.
- Word comments
- Comment threads, replies and resolve, in the margin where they belong. Corpus adds comments only when you ask it to.
- Templates and clause library
- Start from your firm's precedents and approved clauses rather than a blank page, and keep house style consistent.
- Matter guidance
- Set the instructions for a matter once, the client's preferences, the governing law, the tone, and every run follows them.
- Built for teams
- Share matters with colleagues, keep roles tidy, and sign in with SSO.
Faster is the least of it.
Corpus runs only on frontier models, fine-tuned for legal work. When a better model ships, you get it, so your work is always drafted by the best AI there is.

Undertakings
In every matter, Corpus shall:
- (a)read every page of a document before it reviews it, and say what it addressed and what it left for you;
- (b)never silently overwrite your text: every edit to an existing document lands as a tracked change;
- (c)cite only authority it actually retrieved, linked to the exact section;
- (d)keep your numbering, tables, defined terms and formatting intact; and
- (e)leave a clear blank wherever your deal needs a detail it does not have.
