Every legal AI demo ends the same way: the polished output appears in the vendor's web app, and the lawyer asks the only question that matters - "how do I get this into my document?". Legal drafting lives in Microsoft Word, has for thirty years, and every copy-paste round-trip out of it costs something real: formatting breaks, defined terms drift, the version history forks, and the negotiation's Track Changes record - the closest thing a deal has to a chain of custody - gets flattened. The Judicio for Word add-in is built on the opposite premise: bring the toolkit to the document. This is what the review-and-draft-inside-Word workflow actually looks like.
Legal work lives in Word - the tools should too
The case for an add-in over a separate app is workflow arithmetic. A contract turn involves dozens of micro-tasks - tighten this clause, check that deviation, answer "what does the indemnity actually cover", find an authority for a position - and if each one costs an export, an upload, and a paste-back, the tool gets abandoned by the third turn. Inside the task pane, each of those tasks operates directly on the open document: the text you select is the text the AI works on, and the result lands where the work already lives.
One design detail carries most of the value: the document is read once, in place. Ask five questions about the open contract and it is not re-uploaded five times; the add-in grounds every answer in the document in front of you. That is the difference between a tool you consult and a tool you work in.
Tracked changes as the trust boundary
The add-in's core rule is that every AI edit lands as a native Word tracked change - a real revision you accept or reject, author-attributed, sitting in the same review pane as a colleague's markup. Nothing is pasted over your document, formatting and undo history stay intact, and the lawyer's control point is the one Word has always had: the accept button.
This matters for more than comfort. Professional duties of supervision and candour require a human decision on every substantive change, and a redline you can review edit-by-edit is what makes that duty practicable - the same logic we set out in our guide to the AI redlining workflow lawyers trust. Where a very old Word host lacks the Track Changes APIs, the add-in degrades gracefully: edits arrive untracked with a clear warning, never silently.
Drafting inside the document: from brief to clause
Drafting starts from a plain-language brief. Describe what you need - a clause or an entire agreement - and the draft is generated at your cursor, starting blank or from one of your saved drafting templates, so house style arrives with the first word rather than being retrofitted. From there the editing loop stays inside the pane and inside the selection you make.
- Draft from prompt: generate a clause or a full agreement from a brief, blank-start or template-based.
- Rewrite selection: make the selected text stronger, softer, shorter, or plain English - as tracked changes.
- Explain this clause: a plain-English explanation of the selection, with a risk note - useful before you sign off on someone else's drafting.
Because the add-in and the web app share one platform, the templates involved are the same ones your team maintains in Drafting - and a document you have polished can be converted into a reusable, placeholdered template directly from the pane.
Review and redline: playbooks, deviations, untracked edits
Review inside the add-in runs at two speeds. Clause-level: select a provision and ask for a tracked-changes redline of just that clause. Document-level: run a whole-document redline, or - the workhorse for negotiated paper - a playbook review that checks the contract against one of your review templates and flags deviations and missing clauses in place, applying suggested fixes as tracked changes or dropping the rationale into a comment. It is the same playbook discipline we describe in our contract playbook guide, executed where the contract actually is.
Two review utilities earn their place in every negotiation. Detect untracked edits compares the open document against a prior version and surfaces every unmarked change as a redline - the classic counterparty-forgot-to-track problem, solved mechanically. Summarize edits turns the document's accumulated tracked changes into a negotiation memo, so the "what moved in this turn" email writes itself.
| Panel | What it does |
|---|---|
| AI redline | Tracked-changes edits on a selected clause or the whole document. |
| Playbook review | Checks the document against your review playbooks; deviations and missing clauses flagged in place. |
| Detect untracked edits | Compares against a prior version and surfaces every unmarked change as a redline. |
| Summarize edits | Turns the document's tracked changes into a negotiation memo. |
| Document Q&A | Answers about the open contract, with citations back into the text. |
| Legal research | Researches the law and inserts authorities as real Word footnotes. |
| Compare to market | Benchmarks a clause against a corpus of comparable clauses, with per-clause verdicts. |
| Structure check | Defined terms, cross-references, and numbering issues - free, no credits. |
Ask your document and research without leaving it
The questioning tools are where the read-once architecture pays off. Document Q&A is a chat grounded in the open contract, with citations that point back into the text - so "where does termination for convenience bite" gets an answer you can verify by clicking, not a paraphrase you must hunt for. For the drafting positions themselves, compare to market benchmarks a clause against a corpus of comparable clauses with per-clause verdicts, and find firm precedent retrieves your own exemplar language for the point you are drafting.
Legal research follows the same in-document principle: ask the doctrinal question and insert the authorities as real Word footnotes, each backed by a verifiable citation rather than a bare assertion - the standard we argue for in citation-grounded research. For contested propositions there is a triple-grounding option that checks a statement against firm knowledge, market practice, and the law, with confidence levels attached.
Language and hygiene: translate, anonymise, structure-check
Three utility panels round out the workflow. Translate renders the document or a selection into another language without breaking its formatting - the same layout-preserving approach as Judicio's Translation feature. Anonymise finds personal data in the document and redacts it under Track Changes, so the redaction itself is reviewable before it becomes permanent. And the structure check - deterministic, and free of credit cost - flags broken cross-references, undefined defined terms, and numbering problems: the unglamorous errors that survive every human proofread.
Finished documents do not have to leave the ecosystem either: a save-to-Judicio panel uploads the document back to your File Library, where every other tool - review matrices, timelines, deal-set analysis - can pick it up without re-uploading.
One account, one workspace: how the add-in fits the platform
The add-in is a surface, not a separate product. You sign in with your existing Judicio account, the pane shows your credit balance, and every action draws on the same subscription, credits, and matters as the web app - with the pane showing what each run charged, and a pairing-code fallback for environments where the sign-in window cannot complete. Work started in Word is visible to the rest of the platform, and platform assets - drafting templates, review playbooks, firm precedent - are usable from Word.
The practical consequence: a team does not adopt "another tool", it extends the workspace it already governs into the application where drafting was always going to happen anyway. For teams comparing this architecture across vendors, our legal AI buyer's guide covers how to evaluate integration depth honestly.
Rollout and governance: AppSource status, deployment, data
An honest status note: Judicio for Word is currently completing Microsoft AppSource verification. Once the listing is live, individuals will install it from AppSource, and a firm admin can deploy it tenant-wide from the Microsoft 365 admin center's Integrated Apps - no per-user setup. It supports Word on Windows, Mac, and the web, plus perpetual Office 2016 and later, with graceful degradation where an older host lacks a given API. The add-in documentation covers installation, sign-in, and every panel in detail.
On data: all AI processing happens server-side against your own subscription, and your documents and prompts are never used to train AI models. Combined with tracked-changes-only edits, that gives supervising lawyers the two assurances that matter most in a governance review - nothing changes without review, and nothing leaves the engagement. Our vendor security questionnaire covers the rest of the diligence checklist.
Getting started with Judicio
If contract work is where your week goes, this workflow is worth piloting deliberately: pick one live agreement, run a playbook review and a clause-level redline, ask the document three questions, and finish with the free structure check - then count what the round-trips used to cost.
The full toolkit is available in the web app today - start a free trial with the 7-day, 500-credit, no-card trial, watch the Word add-in page for the AppSource listing going live, or talk to us about a firm-wide rollout.
