AI Contract Review for Legal Teams

Your attorneys are confirming boilerplate is boilerplate

A 30-page NDA still requires a full read to confirm the standard clauses are present and the non-standard ones aren't. A legal team reviewing 300 commercial contracts a year spends significant attorney time on work that doesn't need attorney judgment. AI contract review inverts this: the AI reads every clause, classifies it, compares it against your playbook, and flags deviations and missing provisions. The attorney reviews the flagged items, not the whole document.

  • Clause extraction and classification across all standard contract sections

  • Deviation detection against your playbook, flagging non-standard counterparty language

  • Missing provision alerts for required clauses not present in the counterparty draft

  • Risk scoring by section with attorney attention directed to the highest-risk deviations

The problem

Sound familiar?

  • Are your attorneys spending review time confirming standard clauses are present rather than analysing the ones that create real risk?

  • When a counterparty slips a non-standard limitation of liability clause into a routine agreement, does your review process reliably catch it?

Short answer

AI contract review software extracts and classifies every clause, detects deviations from your playbook, flags missing provisions, and scores risk by contract section, so attorneys review the exceptions rather than every paragraph. RaftLabs builds AI contract review systems for legal teams that reduce per-contract review time by 40 to 70 percent on routine commercial agreements, integrating with your CLM and delivering in 8 to 14 weeks at a fixed cost.

Key takeaways

  • AI contract review works best on high-volume, consistently structured contracts - NDAs, vendor agreements, SaaS subscriptions - not highly negotiated M&A documents.
  • Clause extraction accuracy typically runs 92-97%; deviation detection precision runs 85-95%, measured against your own contract library.
  • Every AI-suggested redline requires attorney approval before it reaches a counterparty - the system flags, it doesn't decide.
  • Most projects deliver in 8 to 14 weeks and cut per-contract review time by 40 to 70 percent on routine agreements.

The contract review problem is a volume and attention problem

A 30-page NDA still requires a full read to confirm the standard clauses are present and the non-standard ones aren't. A legal team reviewing 300 commercial contracts per year is spending significant attorney time on work that doesn't require attorney judgment: confirming the confidentiality clause is present, the liability cap is standard, the governing law is correct. Only then can they get to the clauses that actually need their attention.

AI contract review inverts this. The AI reads every clause, classifies it, compares it against your playbook, and flags the deviations and missing provisions. The attorney reviews the flagged items, not the whole document. The routine confirmation work disappears. The detailed judgment work remains.

Capabilities

What we build

  • 01
    Clause extraction and classification

    LLM-based extraction returns each clause as a typed JSON object with clause type, extracted text, page reference, and confidence score, validated against a JSON Schema so hallucinated fields never reach the review interface. NER identifies parties, dates, monetary values, and notice periods as structured data. Covers limitation of liability, indemnification, confidentiality, IP assignment, termination, governing law, and any custom clause types in your playbook.

    GPT-4o · Claude 3.5 Sonnet · spaCy · AWS Comprehend Legal
  • 02
    Playbook deviation detection

    Extracted clauses compared against your defined playbook positions: acceptable ranges, positions you'll accept with modification, and positions requiring escalation. Deviations get a three-tier severity classification, standard, deviation, or high risk, each with the extracted language, the position it deviates from, and why it matters, replacing the manual line-by-line comparison that occupies most of a routine review.

  • 03
    Missing provision detection

    Detects required provisions absent from the counterparty draft against your standard agreement checklist: GDPR DPA clauses under Article 28, warranty disclaimers, IP assignment language, governing law, dispute resolution. When a required provision is silently missing, most reviewers don't notice what isn't there. The system flags the specific absence and the reason it's required.

  • 04
    Risk scoring and prioritisation

    A confidence-scored risk rating per contract section and overall, factoring deviation severity, clause category weight, number of non-standard positions, and counterparty history. High-risk contracts and sections surface first in the review queue. Low-confidence extractions route to a separate manual-attention queue so attorneys know what the AI is confident about and what needs independent judgment.

  • 05
    Redline generation

    When a clause deviates and your playbook defines a fallback position, the system generates a tracked-changes redline comparing counterparty language against your preferred position, saved directly into iManage, NetDocuments, or SharePoint. The AI generates the first draft of the redline, not the final version; attorney review and approval is required before anything goes to the counterparty.

  • 06
    CLM and workflow integration

    Integration into your existing contract lifecycle so AI review is a step in the workflow, not a separate tool requiring export and re-import. Contracts landing in an iManage matter or NetDocuments cabinet trigger review automatically via webhook; SharePoint libraries are monitored via Microsoft Graph API. For organisations without a CLM, we build a lightweight review interface that tracks status and stores results alongside the document.

Frequently asked questions

AI contract review delivers the highest time reduction for contracts with consistent structure and high volume: NDAs, standard service agreements, vendor contracts, SaaS subscriptions, and commercial contracts that follow your organisation's standard templates. For highly negotiated, custom agreements such as M&A documents or complex financing arrangements, AI review provides useful extraction and flagging but requires more significant attorney engagement. We assess your contract mix during scoping and design the system for the contract types where it delivers the highest value.

Playbook encoding is a structured workshop exercise at the start of the project. Your legal team defines for each contract category the clause types that require review, acceptable language ranges, risk weights, and escalation thresholds. This is formalised into a structured playbook document with JSON Schema definitions driving the deviation detection comparison. The playbook is version-controlled so you can track when positions change and why, and accepted or rejected AI suggestions from the review workflow drive iterative refinement.

Extraction accuracy for well-defined, consistently structured clause types using GPT-4o or Claude 3.5 Sonnet with JSON Schema validation is typically 92-97%, measured against a labelled sample from your contract library. Deviation detection precision runs 85-95% and recall runs 90-98% for your most common contract types with well-defined playbook positions. Confidence scoring per extracted clause routes low-confidence extractions to the attorney review queue. Post-deployment accuracy is tracked continuously via the accept/reject feedback loop and reported monthly.

The system includes confidence scoring on its review output. For clauses where extraction or classification confidence is low, the system flags the clause for manual review rather than presenting a potentially incorrect classification as certain. For contract types outside the trained scope, the system surfaces this as a low-confidence review requiring full manual attention. A system that presents uncertain classifications as certain creates a false sense of completeness, which is worse than no AI review at all.
