Third-party paper marked up against your playbook before a lawyer opens it
A done-for-you contract review and redlining automation is an AI agent that reads incoming third-party contracts, compares each clause with your legal playbook and prepares tracked changes, comments and an issues list in Word. A lawyer stays in the loop: they review, edit and approve every redline before anything goes to the counterparty, and they remain responsible for the result. The agent does not give legal advice. BufferSol builds it, connects it to your CLM and document store, and logs every step.

Is this you?
In-house legal teams of one to twenty lawyers, and the commercial or procurement teams they support, who handle a steady flow of customer, vendor, data processing and reseller agreements on the other side's paper.
- Lawyers spend the first hour of each contract finding the same liability, indemnity and auto-renewal clauses.
- Your playbook exists in a Word file or someone's head, and two reviewers give different answers on the same clause.
- Sales and procurement chase legal for status because nobody can see where a contract sits.
- Low-risk vendor paper waits in the same queue as a major customer deal.
- Fallback positions agreed last quarter are hard to find when the next counterparty pushes back.
Today vs done for you
The current way, and the new way
What your team does by hand today, and what the automation does instead, step by step.
How it works today
- A salesperson or buyer emails a counterparty's draft to legal, often without the deal value, term or the commercial context.
- A lawyer or contract manager reads the document from start to finish, hunting for the clauses that matter to your company.
- They compare each clause with a playbook in a Word file or SharePoint page, or from memory, and type tracked changes by hand.
- Questions go back to the business owner by email, and the draft sits while they wait for answers.
- The redline is sent, the counterparty pushes back, and the negotiation history lives across several email threads.
- The signed version is filed in a CLM or a shared drive, often without notes on which positions were conceded.
What it quietly costs you
- · Senior legal time is spent on reading and formatting rather than on the few clauses that carry real risk.
- · Deals and vendor onboarding stall while contracts wait in a single queue with no triage.
- · Inconsistent positions across reviewers create obligations the business does not know it has signed up for.
How it works done for you
- A contract arrives through email, Slack, Salesforce or your CLM. The agent reads it, identifies the agreement type and the counterparty, and pulls the deal record for value and term.
- It splits the document into clauses and compares each one with your playbook: preferred position, acceptable fallbacks and walk-away points, as set by your legal team.
- It prepares a Word draft with tracked changes and margin comments that cite the playbook rule behind each edit, plus a one-page issues list ranked by risk.
- It routes the draft by your rules: a routine vendor agreement goes to a contract manager, while unusual indemnities, uncapped liability or new data transfers go straight to a named lawyer.
- The lawyer reviews, edits and approves the redline in Word or the CLM. Nothing leaves your company without that approval, and the lawyer remains responsible for every change.
- When the counterparty replies, the agent compares their version with yours, flags new edits and suggests the next fallback from the playbook for the lawyer to accept or reject.
- Every comparison, routing decision, edit and approval is logged against the contract, so legal ops can see cycle time and the clauses that cause the most back-and-forth.
Your people
What changes for your team
| Role | Today | Done for you |
|---|---|---|
| Commercial lawyer | Reads every contract line by line and retypes the same changes on indemnity, liability and termination. | Reviews a prepared draft, makes the judgment calls the agent flagged and approves the final redline. |
| Contract manager or paralegal | Chases the business for missing context, tracks versions by email and files signed copies by hand. | Handles routine agreements from the agent's draft and keeps the playbook current with legal's decisions. |
| Head of legal or legal ops | Has little data on where contracts get stuck or which terms counterparties push back on most. | Sees cycle time by agreement type and the clauses that cause the most rounds, and updates the playbook to match. |

Guardrails built in
- A lawyer approves every redline before it is sent; the agent can draft and suggest but cannot send to a counterparty on its own.
- The agent does not give legal advice. It applies the playbook your lawyers wrote and flags anything the playbook does not cover.
- Contracts are processed inside your own tenant with access limited to the legal team and the deal owner, and no client data is used to train models.
- Every clause comparison, suggested edit and human decision is logged with the user, time and playbook version.
Why it hurts today
What teams say about this work
Common complaints from operators, reviewers and industry research.
Research from the contracting profession's main association finds that companies lose a meaningful share of contract value each year through poor contract management, and that most business users find contracts hard or impossible to understand.
A survey of sales and legal professionals found the two sides disagree sharply on how long contract review takes, with many salespeople saying legal does not return documents fast enough and that review slows deals.
Reviewers of a leading CLM platform say parts of it are frustrating to navigate and some features are not intuitive, so contract work still depends on people who know the tool well.
Enterprise CLM users report that implementation is the hard part, with at least one reviewer describing an unpleasant experience working with the implementation partner.

Does the agent give legal advice or replace our lawyers?
No. The agent does not give legal advice. It applies the playbook your lawyers wrote, drafts tracked changes and explains which rule each edit comes from. A lawyer reviews, edits and approves every redline before it reaches the counterparty, and that lawyer remains responsible for the final position. Anything the playbook does not cover is flagged for a lawyer to decide rather than guessed.
What if we do not have a written playbook yet?
Most teams don't have a complete one. During the build we sit with your lawyers, review a sample of signed contracts and past redlines, and write down preferred positions, fallbacks and walk-away points for the clauses you care about most. Your legal team signs off the playbook before the agent uses it, and they can change it at any time as positions evolve.
Does it work with our CLM and with Word?
Yes. Lawyers keep working in Microsoft Word with normal tracked changes and comments. The agent reads from and writes back to Ironclad, DocuSign CLM, Juro, Icertis, SharePoint or iManage, depending on what you use. If you have no CLM, it works from a shared mailbox and a document library, and still keeps a full log of versions and approvals.
How long does it take to go live?
Live in 3 to 6 weeks. The first part covers your playbook, agreement types and routing rules. Then we connect your inbox, CLM and document store, and run the agent on past contracts so your lawyers can compare its drafts with what they actually sent. It goes live on one agreement type first, such as vendor paper, then expands.
What does it cost?
Pricing is quoted after a short scoping call. It depends on how many agreement types you handle, how detailed your playbook is, which systems we connect and your monthly contract volume. We would rather understand your queue and your risk rules than give a generic figure, so the quote you get reflects the work your legal team actually does.
