By LegalSifter, Inc. · HQ Pittsburgh, Pennsylvania, US · 4.0/5 Value-Position score (estimate)
Positioning guardrails
Best for
- In-house legal and contract teams reviewing high volumes of third-party agreements against defined company positions
- Procurement and sales-ops teams that need fast, consistent redlines on NDAs, MSAs and vendor paper
- Mid-market to enterprise organizations handling 100+ contracts a year with a documented playbook or standard terms
- Teams already working in Microsoft Word or Google Docs that want AI review delivered inside those tools
Ideal size: 5–50 reviewers people · Scale-up or enterprise legal/contract ops team with standing positions
Not for
- Solo practitioners or very low-volume teams that cannot justify a $2,750+/year subscription
- Buyers wanting a free, fully self-serve contract tool with no onboarding or playbook setup
- Litigation, e-discovery or matter-management needs; LegalSifter covers pre-signature review, not disputes
- Organizations with no defined negotiation positions and no appetite to build or adopt a playbook

Frequently asked questions
How much does LegalSifter ReviewPro cost?
List pricing is published. Consumption plans run $2,750/year (50 contracts), $7,500 (150), $18,000 (400) and $40,000 (1,000), with unlimited seats and extra volume at $40–$55 per contract. Seat-based plans start at $6,000 per seat for a single seat and fall to $3,500 per seat at 15+ seats, with unlimited contract volume. All subscriptions are annual.
How long until we see value from ReviewPro?
The vendor says 100+ standard playbooks run on day one and that standard implementation and onboarding are included in every subscription rather than charged separately, so a team can begin reviewing live contracts within days. Custom playbook architecture, built from your policy documents, templates or redlined contracts, is a separate one-time service.
Does LegalSifter work inside the tools our team already uses?
Yes. A Microsoft Word and Google Docs add-in is included with every subscription, so reviewers redline in the environment they already work in. ReviewPro also provides its own contract repository, intake ticketing and playbook management on top of the add-ins.
Is our contract data used to train AI models?
The vendor pages reviewed for this profile do not state whether customer contract data is used to train or improve models. LegalSifter lists security and privacy among its core values, but buyers should confirm data-use and model-training terms directly with the vendor before signing.
What kinds of contracts can ReviewPro review?
The vendor advertises 2,000+ pre-built AI Sifters and 100+ standard playbooks covering common contract types, and says ReviewPro produces professional-grade redlines aligned to your positions on third-party paper. LegalSifter also sells managed redlining and contract data-extraction services alongside the software.
Is LegalSifter a full contract lifecycle management system?
Partly. The ReviewPro subscription includes a repository, intake ticketing and metadata on key terms, and the vendor's separate Contract Logix product covers intake-to-renewal CLM. LegalSifter also sells managed contract-management services, so day-to-day CLM administration can be outsourced to its staff.
