A tools-first TAR resource hub for practical, defensible review work.

Summary

TAR Tools Hub is a public resource site built around practical TAR calculators, defensible workflow guidance, and platform-neutral reference materials. We help practitioners understand prevalence, elusion, recall, culling, and related TAR concepts through tools that work regardless of your review platform.

Our approach centers on what works in real-world review workflows rather than theoretical frameworks or vendor-specific implementations.

Mission

Help TAR practitioners implement defensible, proportionate review workflows through practical calculators, clear workflow guidance, and reference materials that work across platforms and vendors.

Scope

We focus on standalone calculators for prevalence, elusion, recall, precision, and culling impact. Our reference materials cover sampling, validation, and defensibility considerations without drifting into platform-specific implementation details or legal advice.

Current scope includes:

• Interactive calculators for common TAR metrics
• Workflow guidance for validation and stopping decisions
• Reference materials for sampling and statistical considerations
• Template documents for protocol development and reporting

Values

• Tools-first: We prioritize practical calculators and workflows over theoretical discussions or platform marketing.
• Defensible by default: All guidance emphasizes defensibility considerations that hold up in meet-and-confer discussions and court proceedings.
• Platform-neutral: Our materials work regardless of whether you use Relativity, Everlaw, Nuix, or any other review platform.
• Clear assumptions: We explicitly state assumptions and limitations so you can determine what applies to your matter.
