What Clausely Does Better

It works for you. Sirion is designed for legal operations teams managing 10,000+ contracts. If you're a freelancer reviewing a client NDA, an employee reading an offer letter, or a renter checking a lease. Sirion isn't for you. The interface, the pricing, and the workflow are built for enterprise procurement departments.

Free to start, instant results. Upload your contract and get a risk score, quoted red flags, and a plain-English explanation in under a minute. No demo call, no implementation timeline, no IT team required.

Plain English. Clausely translates legal language into clear explanations anyone can understand. Sirion's output is built for lawyers and contract managers who already understand legal concepts.

Price. $12.99/month versus enterprise CLM pricing that typically runs $50,000+ per year. For an individual or small business, this isn't a real comparison.

Free contract templates. Clausely includes a free downloadable library of NDA, freelance service agreement, employment offer letter, residential lease, non-compete, and more.

What Sirion Does Better

Portfolio management. Sirion's core strength is managing thousands of contracts at the same time: tracking obligations, renewal dates, counterparties, and risk across an entire contract portfolio. Clausely analyzes one contract at a time for one person.

CLM workflow. Sirion includes the full contract lifecycle: authoring, negotiation, execution, obligation tracking, renewal alerts, and analytics. It's a system of record for enterprise contract operations, not an analysis tool.

E-signature integration. Sirion integrates e-signature directly into the contract workflow. Clausely doesn't offer e-signature.

Compliance and obligation tracking. Sirion monitors ongoing obligations after a contract is signed: payment terms, SLA requirements, renewal windows. Clausely focuses on pre-signature analysis.

Enterprise security. Sirion is built for large organizations with SOC 2 Type II, GDPR compliance, SSO, and enterprise-grade role-based access controls.

Bottom Line

Sirion is a sophisticated enterprise platform. It's built for a corporate legal department, not for someone trying to understand what they're about to sign. If you're a freelancer, a renter, an employee, or a small business owner, Clausely was built specifically for you.
