Review comments on a legal document

Paste a contract, brief or memo. River adds comments anchored to the passages that matter, ordered by consequence, each with suggested wording.

Context to provide

River reads a legal document from start to finish and adds review comments anchored to the passages that need attention. It works on contracts, briefs, memos and letters. Each comment names the issue, explains why it matters for the side you represent, and suggests wording or a fix. A short summary at the top lists the issues in order of consequence, so the most important ones are dealt with first.

The comments are not a quota. A tight two-page letter may need five comments and a long agreement may need forty. River covers substance before style: missing protections, one-sided risk, ambiguous obligations, undefined terms, and arguments a court or the other side will test. Drafting points come last and are grouped, so they do not drown out the issues that change outcomes.

This is for lawyers, paralegals and business owners who want a careful second read before a document goes out or gets signed. It is a review aid, not legal advice, and the comments say where a lawyer's judgement is needed.

What makes a review comment useful

A useful comment does three things: it points at the exact words, says what could go wrong because of them, and offers a fix. "Unclear" is not a comment. "Payment due 'promptly' gives no date, so late payment is hard to prove; say 'within 30 days of the invoice date'" is. Comments that carry their own fix get resolved quickly, because the reader can accept or reject them on the spot.

Order matters as much as content. A reviewer who leaves forty comments of equal weight hands the prioritising back to the author. Start with the issues that change who bears a loss or whether an obligation can be enforced, then the gaps, then clarity, then style. Say which side each comment serves, since the right answer for a vendor is often the wrong one for a customer.

Finally, read the document as a whole. Many problems sit between clauses rather than inside one: a liability cap that does not mention the indemnity, a defined term used two ways, a termination right with no matching transition terms. Those are the comments a clause-by-clause skim misses.

How it works

  1. Paste or attach

    Add the document and, if you like, say who you represent and what matters most.

  2. River reads it all

    The whole document is read first, so comments can account for how clauses interact.

  3. Review the comments

    Comments sit on the passages they concern, with a summary of the biggest issues at the top.

  4. Follow up in chat

    Ask for a redline of the top issues, or a short email to the other side.

What you get

  • Comments anchored to the exact passages, each with the issue, why it matters and a fix
  • A short summary at the top listing the most consequential issues first
  • Substance before style: risk allocation, missing terms, ambiguity, then drafting
  • Comments written for the side you represent, not a generic balance
  • Issues that sit between clauses, such as caps, indemnities and defined terms that do not line up

Common questions

What kinds of documents can it review?

Contracts, letters, briefs, memos and policies. For contracts the comments focus on risk allocation, missing terms and ambiguity; for briefs and memos, on the structure of the argument, unsupported statements and authority the other side will cite. River does not check citations against a legal database, so verify any authority it questions.

How many comments will I get?

As many as the document needs, and no padding. A short, clean letter may get a handful; a long first draft from the other side may get dozens. The summary at the top lists the issues that matter most, so you can stop there if time is short.

Does this replace a lawyer's review?

No. It is a careful second read that catches issues and suggests fixes, but it does not know your full situation or the law of every jurisdiction. Comments that turn on a legal judgement say so. Use it to make a lawyer's review faster, or to decide whether you need one.

What if I disagree with a comment?

Resolve or delete it. Some flagged points will be deliberate choices or acceptable risks for your deal. Each comment explains its reasoning so you can make that call quickly, and you can ask River in chat to reconsider a comment with more context.

Can it mark up the document instead?

Yes. After the review, ask River to redline the top issues, and it will propose replacement wording for those passages. Keeping comments and edits separate lets you decide what to change before anything is rewritten.
