Ontra (formerly LegalSifter) vs Della AI

Ontra (formerly LegalSifter) excels at delivering consistent, high-volume contract review by combining its proprietary AI software with a dedicated team of legal professionals. This managed legal service model is designed for operational efficiency, handling thousands of standardized agreements like NDAs and sales contracts with a predictable, subscription-based cost. For example, clients report a 70-80% reduction in internal legal review time for routine agreements, as Ontra's human-in-the-loop system ensures quality control and handles escalations directly.

Della AI takes a different approach by providing a collaborative review platform and an AI agent that empowers in-house legal teams. Its strategy focuses on augmenting lawyers with tools for clause extraction, risk analysis, and collaborative negotiation within a single workspace. This results in a trade-off: while it requires more internal oversight than a fully managed service, it offers greater transparency, control, and the ability to build institutional knowledge by keeping the review process within the legal department.

The key trade-off: If your priority is scaling the review of high-volume, lower-risk contracts (e.g., procurement, NDAs) with a hands-off, predictable operational cost, choose Ontra. If you prioritize retaining control, enhancing your team's capabilities, and managing complex, negotiated agreements with a flexible AI co-pilot, choose Della AI.

Ontra (formerly LegalSifter) excels at providing a predictable, high-volume managed legal service because it combines its AI review software with a dedicated team of legal professionals. For example, clients can achieve a consistent 24-48 hour turnaround on standard NDAs and vendor agreements, effectively outsourcing the review process. This model is ideal for procurement or sales teams needing to scale contract operations without expanding internal headcount, as it guarantees a specific service-level agreement (SLA) and reduces internal legal team burden.

Della AI takes a different approach by focusing on a collaborative review platform and AI agent designed to augment, not replace, your internal legal team. This results in a trade-off: you retain full control and institutional knowledge, but you must manage the process and training internally. Della's strength lies in its AI-powered clause library and collaborative redlining, which allows multiple stakeholders to work within a unified platform, improving version control and reducing email clutter during negotiations.

The key trade-off is between outsourced efficiency and in-house control with augmentation. If your priority is scaling high-volume, lower-risk contract reviews (e.g., NDAs, MSAs) with a fixed, predictable cost, choose Ontra. Its managed service model is a proven solution for operationalizing legal work. If you prioritize enhancing the speed and collaboration of your existing legal team on complex, negotiated agreements while maintaining oversight, choose Della AI. Its platform is built for legal professionals who want an AI co-pilot, not a replacement.
