Every company signs contracts faster than it can carefully read them. A vendor MSA arrives, a lease lands during a move, an NDA shows up before a meeting - and someone has to check every clause against what the company can actually accept. Skim it and you miss the clause that hurts; send everything to outside counsel and you pay for hours of work on documents that are mostly fine.
Sharper turns the contract stack into a knowledge base you can question. Upload the agreements and your own contract playbook, then ask what deviates. Sharper reads every clause, checks it against your standards, flags what violates them - and what is missing entirely - compares negotiation drafts, and writes a review report with suggested redline language. Every finding cites the exact clause it came from, which is precisely the standard legal work demands.
What is contract review with a knowledge base? You upload contracts plus the playbook that defines your company's standard positions, then ask questions in plain English. Sharper answers from those documents - extracting terms, flagging deviations by severity, and citing the clause behind every finding so a reviewer can verify each one in the source.

The setup: one playbook, four contracts
Brightpath Software is a startup with a five-document pile on its desk:
- The contract playbook - Brightpath's standard positions: liability caps of at least 12 months of fees with carve-outs, mutual indemnification only, payment terms, escalation caps for leases - plus four hard dealbreakers that require General Counsel approval, like personal guaranties and exclusive out-of-state arbitration.
- Orbita MSA, draft v1 - a cloud vendor's opening draft, written the way opening drafts usually are.
- Orbita MSA, draft v2 - the same agreement after a round of negotiation.
- Kestrel NDA - a mutual NDA for financing discussions.
- Harborview lease - a five-year office lease for 12,400 square feet.
The question every founder, ops lead, and in-house lawyer actually has: which of these can we sign, and what exactly do we push back on?
Step 1 - Upload the contracts and the playbook to build the knowledge base
All five PDFs go into a single knowledge base. Sharper parses and indexes each agreement, clause by clause, and prepares the set for question answering.
One knowledge base holds the whole deal stack - and the playbook sits alongside the contracts, open here at the section that matters most: the dealbreakers reviewers must escalate.
How Sharper works, in two moves. First, you build a knowledge base: upload your documents once and Sharper parses and indexes them into a reusable, searchable collection. Second, you ask: start a new task, select that knowledge base, and ask any question in plain English. Sharper searches only the selected knowledge base and answers from it - so every finding is grounded in your contracts, not generic legal boilerplate.
Including the playbook is the move that changes everything. Without it, an AI can only tell you what a contract says. With it, Sharper can tell you what a contract says that your company cannot accept.
Step 2 - Extract the key terms, with clause-level citations
Start with the vendor's opening draft.
The question: "What are the key terms of the Orbita MSA v1 - fees, payment, term, renewal, liability cap, and governing law?"
Every term carries its clause citation - $18,500/month (§1.1), Net 15 (§1.2), a 24-month auto-renewal with a 90-day notice window (§2.2) - with the contract open beside the answer and the cited passages highlighted.
This is the grounding that legal work requires: not a summary you have to trust, but an extraction you can verify clause by clause without leaving the page.
Step 3 - Flag what violates your playbook, and what's missing
Now the differentiator. Ask Sharper to review the draft against the company's own standards.
The question: "Review the Orbita MSA v1 against our contract playbook. Which clauses violate our standards, and what's missing entirely?"
A severity-tiered review: three dealbreakers requiring GC escalation - one-way indemnification (§4.1-4.2), New York law with binding arbitration (§9.1-9.2), and vendor ownership of all work product (§5.1) - each citing both the offending clause and the playbook rule it violates, with more violations tiered below.
Two things here are hard to do by skimming. First, every finding is a cross-reference: the contract clause on one side, the playbook rule it breaks on the other. Second, Sharper flags what is not there at all - v1 has no data-breach notification clause and no cyber-insurance requirement, both mandatory under the playbook. Missing clauses are the failure mode human skimming is worst at.
The same review works on a completely different contract type:
The question: "Does the Harborview lease meet our playbook? Flag everything a founder should push back on."
The lease review leads with a dealbreaker - a personal guaranty by both founders (§3.1), prohibited by two playbook rules - and includes practical pushback: remove it entirely, with a burn-off guaranty as the GC-approved fallback. Hover a citation and Sharper shows the source card; click through to the lease itself.
Note what Sharper adds beyond the flag: negotiation advice. The uncapped CPI escalation gets quantified, and the guaranty gets a fallback position. That is the difference between a checklist and a reviewer.
Step 4 - Compare two drafts: what we won, what's still open
After a negotiation round, the vendor sends v2. The question that takes an associate an afternoon:
The question: "Compare Orbita MSA v1 and v2 - what changed, what did we win, and what is still open?"
The redline summary: all three v1 dealbreakers are fully resolved - mutual indemnification, customer ownership of work product, Delaware courts - plus eight more wins including a 12-month liability cap and two entirely new clauses. Four items remain open, led by a High-severity one: the cap still covers indemnification and data incidents. The full clause-by-clause diff is saved as a document.
The subtle catch in that table is exactly the kind of thing that slips through late-stage reviews: v2 raised the liability cap but quietly dropped the confidentiality carve-out - so a data breach is now capped at 12 months of fees. Better headline number, worse fine print. Sharper caught the trade.
Step 5 - The deliverable: a redline-ready review report
Finally, the closer - turn the analysis into the document you'd hand to counsel or the CEO.
The request: "Generate a contract review report for the Orbita MSA v2: key terms, remaining playbook violations with severity, a suggested redline for each, and a recommendation - sign, negotiate, or walk."
A saved, structured report: recommendation NEGOTIATE - one round from signing, a full key-terms compliance table, and each open item with severity, quantified risk (a data breach capped at ~$222K of fees), and ready-to-paste redline language for the next turn of the document.
The report includes actual redline text - replacement clause language for each open item - so the next email to the vendor practically writes itself.
What makes Sharper different for contract review
- Every finding cites its clause. Terms, flags, and comparisons link to the exact section in the source contract - the verification standard legal work requires.
- It reviews against your playbook. Sharper applies your company's standards and dealbreakers, not generic advice - and cross-references every violation to the rule it breaks.
- It catches what's missing. Absent breach-notification and insurance clauses get flagged as loudly as bad ones - the gap human skimming misses most.
- It diffs negotiation drafts. Version-to-version comparison shows what you won and what's still open, including regressions hidden behind improved headline terms.
- It produces the deliverable. A severity-ranked review report with suggested redlines and a sign / negotiate / walk recommendation, saved as a document you can share.
The time saved
Reading four contracts against a playbook, cross-referencing every clause, diffing two drafts, and writing up findings with proposed redlines is a day of legal-adjacent work - or a real invoice from outside counsel. With Sharper it is a short session of questions, and what reaches your lawyer is not a pile of PDFs but a cited, severity-ranked report - so their hours go to judgment, not extraction.

FAQ
What kinds of contracts can Sharper review?
Any agreement you can upload: vendor and customer MSAs, NDAs, leases, SOWs, DPAs, and more. In this walkthrough one knowledge base holds a SaaS MSA (two drafts), an NDA, an office lease, and the company playbook.
How does Sharper know what my company considers risky?
You upload your contract playbook - your standard positions and dealbreakers - alongside the contracts. Sharper reviews each clause against those rules and cites both the contract clause and the playbook rule for every flag.
Can Sharper catch clauses that are missing, not just bad ones?
Yes. In this walkthrough it flagged the absence of a data-breach notification clause and a cyber-insurance requirement - both mandatory under the playbook, and both invisible to a reader who only evaluates the text that is present.
Can Sharper compare two versions of a contract?
Yes. Ask it to compare drafts and it produces a redline summary: what changed, what was won, what remains open by severity - including regressions hidden inside otherwise-improved clauses - plus a saved clause-by-clause diff.
Does this replace a lawyer?
No. Sharper accelerates the review - extraction, playbook checks, diffs, and a drafted report with proposed redlines - with every finding cited so counsel can verify it quickly. Judgment calls and final sign-off stay with your lawyer.
