# eDiscovery Decoder > Agent-ranked eDiscovery AI news, technology-assisted review (TAR) calculators, a TAR glossary, and a curated reference library. Educational material, not legal advice. TAR calculations and news are available to agents through a free, read-only MCP server at https://mcp.ediscoverydecoder.com/mcp (no login). See the MCP server setup page for supported tools. ## Calculators - [eDiscovery prevalence and sample results calculator](https://ediscoverydecoder.com/calculators/prevalence-results/): Estimate prevalence, confidence bounds, responsive volume, and review burden from an eDiscovery random sample. - [Elusion and recall calculator](https://ediscoverydecoder.com/calculators/elusion-recall/): Estimate elusion, remaining responsive material, and recall from validation sample results. - [Richness and yield calculator](https://ediscoverydecoder.com/calculators/richness-yield/): Estimate collection richness, projected responsive volume, and review yield from reviewed results. - [Precision, recall, and F1 calculator](https://ediscoverydecoder.com/calculators/precision-recall-f1/): Calculate precision, recall, and F1 from true-positive, false-positive, and false-negative counts. - [Control-set recall calculator](https://ediscoverydecoder.com/calculators/control-recall/): Validate recall against the responsive portion of a control set and communicate the result clearly. - [Culling impact calculator](https://ediscoverydecoder.com/calculators/culling-impact/): Compare non-responsive removal with responsive loss to evaluate the selectivity of a culling decision. ## Reference - [TAR glossary](https://ediscoverydecoder.com/glossary/): 26 plain-language definitions of TAR and validation terms. - [Read Me First: TAR Primer](https://ediscoverydecoder.com/resources/tar-primer-readme/): A high-level primer for understanding what Technology-Assisted Review is, how the workflow moves from goals to validation, and how prediction scores and metrics should be interpreted before relying on TAR in a real matter. - [Start Here: Additional Overview Resources](https://ediscoverydecoder.com/resources/start-here/): Use these after the primer when you want the primary overview materials behind the TAR workflow, including EDRM, FJC, and Grossman/Cormack resources. - [Authoritative Guides & Standards](https://ediscoverydecoder.com/resources/authoritative-guides-standards/): Neutral or semi-neutral references users can rely on when learning TAR or building defensible workflows. - [AI eDiscovery: Workflow Resources](https://ediscoverydecoder.com/resources/ai-ediscovery-workflow-resources/): Workflow-focused resources for connecting AI assistants to eDiscovery context, MCP servers, and legal plugin patterns while keeping human review, read-only defaults, and non-legal-advice boundaries visible. - [AI in eDiscovery: Practical Governance Resources](https://ediscoverydecoder.com/resources/ai-in-ediscovery/): Resources for teams using generative AI, analytics, classifiers, or AI-assisted review features in litigation workflows. - [Court Guidance & Case Law](https://ediscoverydecoder.com/resources/court-guidance-case-law/): Key decisions and legal themes users should understand before proposing or challenging TAR. - [TAR Workflow Summary](https://ediscoverydecoder.com/resources/tar-workflow-summary/): A practical workflow map for users who need to understand what happens from collection through validation. - [Validation, Metrics & Sampling](https://ediscoverydecoder.com/resources/validation-metrics-sampling/): Core measurements and quality-control concepts users need to understand before relying on TAR outputs. - [Practical Checklists & Protocol Prompts](https://ediscoverydecoder.com/resources/practical-checklists/): Questions users can take into a Rule 26(f) conference, vendor selection meeting, or internal review planning session. - [Vendor Education & Tool Documentation](https://ediscoverydecoder.com/resources/vendor-education-tool-docs/): Useful vendor resources when they explain concepts clearly.
