What makes it different

Five things that set us apart.

On-device PII protection

Names, emails, IDs, and other identifiers are anonymised before anything leaves your machine. Three protection levels and per-document controls.

Multi-document sync

Link two open Word documents into a workspace. Changes proposed in the lead flow across to the counterpart as tracked changes for approval.

Clause library with smart match

Index your firm's contracts once. The AI draws in relevant clauses as you draft - no copy-paste, no hunting through folders.

Firm-wide playbook in every document

Upload your firm's playbook once: negotiation positions, model clauses, drafting conventions, risk thresholds. The AI honours it on every request, every matter.

Whole-document edit consistency

Change one clause and the AI catches every knock-on across the document - defined terms, cross-references, reciprocal obligations, carve-outs, even renumbered clauses.

Drafting from scratch

Draft a complete document in minutes.

From NDAs to legal opinions to litigation notices - start blank, describe what you need, and let the AI walk you through a guided drafting flow.

Full contract drafts prepared to your spec.

From a blank page to a complete first draft in your style. The AI runs an intake, plans the structure, and drafts in real time.

Drafts in your style.

Upload one .docx precedent. The AI replicates its fonts, headings, numbering, margins, and headers - drafts come back ready to send.

Your precedent library, one click away.

Pick from your saved precedents in one click. Rename or delete from the list, and past completed contracts are kept for reference.

Drafts, double checked.

The moment a draft finishes, the AI offers to review it for redundancies, duplications, and inconsistencies.

AI redlining

Redline anything in plain English.

The strongest redline engine for Word. Describe the change; review proposals change-by-change, or in bulk; apply only what you approve - all as tracked changes.

Just say it. The AI redlines.

Describe what you want changed in plain English. The AI proposes precise tracked-change edits - accept, edit, or reject each one.

Severity-classified changes.

Every proposed change is graded Critical, Important, Moderate, or Minor. Filter the list to focus on what matters this round.

Refine the AI's wording before you apply.

Rewrite any proposed wording before it touches the document; only your approved version reaches the document.

Pinpoint the AI to your selection.

Highlight any text and the AI scopes its focus there while staying aware of the rest of the document.

One change. Every consequential edit caught.

Change one clause and the AI scans the whole document for consequential edits - defined terms, cross-references, reciprocal obligations, carve-outs, even renumbered clauses.

Comment workflows

Comments, end to end.

Insert review comments, draft replies to opposing counsel, edit or delete existing threads, export a schedule of deviations, or implement reviewer comments as tracked changes.

Severity-tagged margin comments on any draft.

Have the AI review the document and propose margin comments - flagging risks, one-sided provisions, missing protections, drafting issues and the like. All with your client's best interests in mind.

Bulk-reply to opposing counsel's comments.

Filter the unresolved comments by author. Add per-comment guidance where needed; the AI drafts professional threaded replies.

Soften, sharpen, or correct any comment.

Existing comments can be reworded, softened, sharpened, or corrected on demand. The AI proposes; you approve.

Implement any comment as a tracked change.

Convert reviewer feedback into actual edits. Select which comments to implement; the AI drafts the precise tracked changes.

Apply one. Apply all. Your call.

Per-proposal control on every type: changes, comments, replies, updates, deletions. Apply individually or in bulk.

Reviewing redlines

Review every redline - opposing or internal.

Purpose-built for reviewing tracked changes - opposing counsel's or your own team's. Accept, reject, edit, or counter-propose - with the AI's recommendation on every change.

AI-recommended actions on opposing counsel's redlines.

The AI reviews every tracked change opposing counsel made and recommends an action: Accept, Reject, Edit, or Comment, with reasoning.

AI-recommended actions on internal team redlines.

The AI reviews every tracked change from your team or client and recommends an action: Accept, Reject, Edit, or Comment, with reasoning.

Guide responses one change at a time, or in bulk.

Steer how the AI recommends responding to each tracked change. Add per-paragraph guidance, or standing instructions that apply across the whole matter.

One-click override on any AI recommendation.

Override any AI recommendation in one click. Accept, Reject, Edit, or Comment instantly.

Add custom guidance to any proposal.

Don't like a proposal? Add custom guidance ("make it firmer", "preserve the cap") and the AI regenerates just that one change.

Multi-document workspaces

Coordinate edits across linked documents.

Link two or more open Word documents into a workspace. When the AI judges a change has a counterpart in the other document, it flows through as a tracked change ready for review.

Group related agreements into a single workspace.

A workspace ties your matter's open documents together. Once grouped, the AI treats them as one connected set, so edits and comments can flow between them.

Edit one document, the AI makes changes across related documents.

Edit one document; the AI works out the corresponding tracked changes the linked documents need, each ready for your review.

Comments, replies, and deletions flow across linked documents.

Multi-document sync covers more than tracked changes. Comments, replies, edits to comments, and deletions can all flow across the linked documents.

Knowledge & references

Bring in the context the AI needs.

Per-document attachments, a persistent firm-wide playbook, audio transcription, OCR, and live web search - the AI works with everything you've got.

Attach PDFs, Word files, and audio as background for the matter.

Attach unlimited reference documents - PDFs, Word files, images, audio. The AI uses them as context for any task: redlines informed by precedents, summaries of long submissions, comparisons against opposing-party drafts, deposition analysis, the lot.

Your firm's playbook, loaded into every document.

Upload your firm's playbook once: negotiation positions, drafting conventions, model clauses, risk thresholds, policies, client guidelines, whatever else matters. The AI defers to it across every document.

Real-time legal research, cited inline.

Real-time research baked in. The AI searches the web for current legislation, court rulings, and regulatory updates - jurisdiction-aware on every search.

Clause library

Your past contracts, working for you.

Index a folder of your contracts. Our system extracts every clause and organises them by category. The AI then draws from your library where applicable as you draft - or you can pick from a searchable picker.

Turn your past contracts into a reusable clause library.

Connect your past contract clauses. Our system connects to all your past contracts, extracts every clause type for you, and stores them in your personal cloud library, searchable, reusable, yours.

Your library, drawn on automatically as you draft.

Subject to your permission, the AI consults your clause library. If anything in your past contracts is genuinely relevant, it's drawn in as drafting context automatically, thereby bringing in your own best practice clauses.

Pick a clause from your library; the AI drafts in its style.

Browse and search your library. Select one or more clauses to use. The AI drafts in their style - same structure and substance.

Your most-used clauses, one tap away.

Favourite the clauses you reach for most. A dedicated filter pulls them up instantly - your firm's go-to wording, always at the top.

Personalisation, privacy, and support

Make it yours. Keep it private.

Per-matter settings, profile preferences, and matter auto-detection let the AI work the way you do, while on-device PII protection and tracked-changes audit trails keep every request confidential and reviewable. When the AI isn't what you need, a human legal assistant is one click away in live chat - 24 hours a day.

Auto-detects your matter type and adapts mode and interface.

Contracts, letters, litigation, opinions, notices - the addin reads the document and tailors its interface to the matter type, giving you the best experience for each type.

Per-matter settings: party, governing law, standing instructions.

Set the AI's perspective once per matter: the party you're acting for, the governing law, and any standing instructions. The AI honours them on every request.

Set tone, structure, and drafting style once.

Tell the AI how you write - tone, comment structure, drafting style - and it follows your preferences on every matter, every time.

External Counsel, In-House, or Business - the AI adapts.

Pick your role and the AI adapts how it frames advice - third-person for external counsel, first-person for in-house, jargon-free for business professionals.

Personal data anonymised before it ever reaches the AI.

Sensitive information stays local. Personal data is anonymised before any request reaches the AI and restored on the way back.

Nothing applied silently - every edit is tracked.

Every AI edit lands as a Word tracked change with author and timestamp. Accept, reject, or edit each one the same way you'd review a colleague's markup.

Real legal assistants, one click away.

Live chat directly inside Word, 24 hours a day. For the moments when the AI isn't what you need, a human is one click away.
