Can I review a contract without Microsoft Word at all?

Yes. Reviewing means reading, understanding, and annotating the document, none of which requires Word specifically. A browser-based reviewer, a PDF annotator, or another word processor can all do the job. You only need Word, or a Word-compatible editor, when you have to edit the underlying text in tracked changes for a counterparty who expects that format, or when you are producing a formatted execution copy.

Is it safe to move away from tracked changes?

It depends on the audience. For your own analysis and for sharing observations with colleagues, structured notes and links are often clearer than tracked changes. But formal negotiation between parties still commonly runs on tracked-changes Word files, and that convention is widely expected. A practical pattern is to think and annotate in a reviewer, then apply the actual edits as tracked changes in Word when you send the document back to the other side.

What is wrong with Word comments for contract review?

Nothing, at small scale. The friction appears on long, heavily reviewed contracts, where the comment margin becomes dense and hard to scan, and where comments can lose their anchor when the surrounding text is edited or moved. Word comments also assume the recipient opens the file in Word; they do not travel cleanly to phones, tablets, or other editors.

How do I share a marked-up contract with someone who does not have Word?

Either export to PDF, which most people can open but which flattens your markup into a static file, or use a browser-based tool that opens with a link and needs no installation. The second keeps your notes and links interactive for the recipient. Whichever you choose, confirm the other side can actually see your annotations before you rely on them having read your comments.

Will I lose my formatting if I review outside Word?

You should not, if the tool exports back to Word or PDF cleanly. The safe approach is to keep the authoritative, formatted document in Word as your system of record, and treat the reviewer as a place to read and annotate a copy. Do the structural review outside Word, then carry the resulting edits back into the Word file so the execution copy keeps its intended formatting.

Do free contract-review tools handle confidential documents responsibly?

That varies by tool, so check before uploading anything sensitive. Look at what the tool does with your document, whether it stores or transmits the text, and whether processing happens in your browser or on a server. For highly confidential agreements, prefer tools that are explicit about handling and retention, and when in doubt keep the review to an offline or trusted environment.

Is a dedicated reviewer overkill for a short, simple contract?

Often, yes. For a two-page agreement you know well, Word or even a printout is perfectly adequate, and adding a tool would only slow you down. Structured review tools earn their place on longer, denser, or unfamiliar contracts, where clause navigation, cross-reference tracking, and shareable notes save real time and catch real problems.

Can I still sign and execute a contract I reviewed outside Word?

Yes. Reviewing a contract in another tool has no bearing on how it is executed. Execution happens on the final agreed text, usually a clean Word or PDF file, through wet signature or an e-signature service. The review tool is where you decide what the text should say; the signing happens on the finished document regardless of where you did your thinking.

Weave vs Word

A free alternative to marking up contracts in Microsoft Word

Most people review contracts the way they were taught to review any document: they open it in Microsoft Word, switch on Track Changes, and start leaving comments. Word is a capable, near-universal editor, and for writing prose it is hard to beat. But reviewing a contract is a different job from writing one. Reviewing means understanding how a document is structured, following how one clause depends on another, recording what you think about specific language, and sharing that thinking with people who may never open the file in Word at all.

This page looks honestly at where Word does that job well and where it gets in the way, and at what a purpose-built contract-review workflow actually needs. It is written to be useful whether or not you ever use a dedicated tool. Nothing here is legal advice; it is about the mechanics of reading and marking up an agreement so that your review is clear, complete, and easy for others to act on.

What a good contract-review workflow actually needs

Before comparing tools, it helps to name the work. Reviewing a contract is not proofreading. You are checking whether the words create the obligations, rights, and protections your side expects, and whether anything is missing, ambiguous, or one-sided. A workflow that supports that has a few concrete requirements, and they are the yardstick for judging any tool, Word included.

Structure you can see and navigate

A contract is not flat text; it is a hierarchy of clauses, sub-clauses, definitions, schedules, and annexes. A reviewer constantly jumps between them: from an indemnity clause to the definition of Losses, from a payment term to the schedule that sets the figures. A good workflow lets you see that structure at a glance and move through it quickly, rather than scrolling through undifferentiated pages hunting for a clause number.

Notes that stay attached to the exact language

The value of a review lives in the margin: 'this cap is too low', 'undefined term', 'inconsistent with clause 7.2'. Those notes are only useful if they stay pinned to the precise words they refer to. When a comment drifts away from its anchor, or collapses into an unreadable thread, the reasoning behind the review is lost even though the words are still on the page.

The ability to connect related clauses

Risk in a contract usually lives in the relationship between clauses, not in any single one. A limitation of liability interacts with an indemnity; a termination right interacts with a notice period; a defined term is used forty pages away from where it is defined. Being able to link one passage to another, and to see those connections later, is often the difference between a surface read and a real review.

Sharing and versioning that anyone can join

A review is rarely a solo act. You send it to a colleague, a counterparty, or a manager, and it comes back changed. The workflow needs to let anyone open your markup without friction, and it needs to keep an honest history of what changed between drafts so nobody has to reconcile versions by eye.

Where Word is genuinely limited for reviewing contracts

Word was designed to produce documents, and it does that superbly. The friction shows up specifically in the review phase, when you are trying to understand and annotate a document rather than write one. These are not bugs; they are the natural consequences of a page-and-prose model applied to a structured legal instrument.

It treats a contract as flat pages, not clauses

Word sees a stream of paragraphs flowing across pages. It has no built-in concept of a clause, a defined term, or a cross-reference as a distinct object. Numbering is often manual or fragile, so a reviewer navigates by scrolling and searching rather than by structure. On a long agreement, simply finding the clause you need becomes a tax on every pass through the document.

Comments sprawl and detach from the text

The comment margin works well for a handful of notes. On a heavily reviewed contract it becomes a dense column that is hard to scan, and comments can lose their anchor when text is edited, cut, or pasted, leaving a remark floating with no clear referent. Threaded replies help, but the margin was never meant to hold the structured reasoning of a full clause-by-clause review.

There is no real sense of cross-references

When clause 9 says 'subject to clause 12', Word cannot show you clause 12 without you going to find it, and it cannot tell you that a defined term is used but never defined, or defined but never used. The connective tissue of the contract, the part where much of the risk hides, is invisible to the tool, so it lives only in the reviewer's memory.

Track Changes and sharing assume everyone has Word

Tracked changes and margin comments are only legible to a recipient who also has Word (or a close-enough viewer) and knows how to use its reviewing features. Send the same file to someone on a phone, a tablet, a different word processor, or an unfamiliar version, and formatting can shift, comments can render oddly, and tracked changes can be accepted or lost by accident. The markup is portable only within Word's own world.

Version reconciliation is manual and error-prone

When a contract goes back and forth, you end up with a chain of files: v3, v3-clean, v3-final, v3-final-JS-edits. Word's Compare feature can diff two of them, but keeping an authoritative history, knowing which version is current, and merging edits from several reviewers is manual work that people do by naming conventions and hope. Mistakes here, signing the wrong version, missing a late change, are among the most costly in contracting.

What an alternative should offer

An alternative to Word for the review phase does not need to replace Word for everything. It needs to do the review-specific work that Word leaves to the reader. In practice that means turning the contract from a flat file into something structured, annotated, and shareable, while still handing you back a normal Word or PDF document at the end.

Clause structure: parse the agreement into its clauses and sub-clauses so you can see and jump around the document by its own architecture, not by page number.
Notes threaded to the text: annotations that stay pinned to the exact words they describe, organised so you can read your whole review as a coherent set of observations rather than a sprawling margin.
Clause-to-clause links: the ability to connect a passage to the definition, schedule, or conflicting clause it relates to, and to follow those links later.
Easy sharing with anyone: a way to send your marked-up contract to a colleague or counterparty who can open it in a browser without owning, installing, or knowing Word.
Version history: an automatic, honest record of what changed between drafts, so you can compare and restore rather than reconcile files by hand.
Export back to Word and PDF: because execution copies, and many colleagues, still live in those formats, the tool should return a clean document at the end of the review.

Where Weave fits

Weave is a free, no-login tool to read, mark up, and connect any contract in your browser. It is built for the review phase specifically: it reads a contract as a set of clauses you can navigate, lets you attach notes to the exact language and draw links between related clauses, and opens for anyone you share it with without asking them to install anything. When the review is done, you take the document back into Word or PDF for editing and execution. It is meant to sit alongside Word, not to argue with it.

A pragmatic way to combine the two

You do not have to choose one tool for the whole life of a contract. The cleanest approach is to match the tool to the phase: draft and finalise in Word, where prose and formatting matter most, and do the reading and mark-up in a structured reviewer, where clause navigation, threaded notes, and easy sharing matter most. Move the document between them, keeping Word as the system of record for the executable text and using the reviewer as the place where thinking happens. This keeps you compatible with everyone who expects a Word file while sparing your review the friction of doing structured work in a prose editor.

When Word is still the right tool

Drafting from scratch — Word's typing, formatting, styles, and numbering tools remain excellent for writing new language and shaping how a document reads.
Producing the execution copy — the clean, final version that gets signed almost always needs to be a polished Word or PDF file, and Word makes that copy well.
Precise formatting and house style — cover pages, defined-term styling, cross-reference fields, tables of contents, and firm templates are Word's home ground.
Working with people who only use Word — if every party in the deal lives in tracked changes, staying in Word avoids conversion friction and meets people where they are.
Formal redlining between two law firms — the established convention of exchanging tracked-changes Word files is widely understood and expected in many negotiations.
Offline, self-contained editing — when you need a single file on your own machine with no browser or account involved, a desktop word processor is the simplest answer.

What to look for in a contract-review tool

Clause structure — it should read the contract as clauses and sub-clauses you can navigate, not as flat pages you scroll through.
Notes anchored to the text — annotations must stay pinned to the exact words and be readable as a whole, not scattered down a margin.
Clause-to-clause links — you should be able to connect related passages (definitions, schedules, conflicting clauses) and follow those connections later.
Frictionless sharing — anyone you send it to should be able to open and read your markup without installing software or creating an account.
Version history — the tool should keep an automatic record of changes between drafts so you can compare and restore instead of reconciling files.
Export back to Word and PDF — it must return a clean, standard document for editing and signing, so the review does not trap your contract in a proprietary format.
No lock-in — free to try, and easy to get your contract and your notes back out, so the tool earns its place on each document rather than owning your workflow.
