Nested Knowledge Documentation

Nested Knowledge is a systematic review and evidence synthesis platform built to compress months of review work into weeks — with AI features that are traceable, validated, and aligned to Cochrane’s RAISE recommendations for responsible AI in evidence synthesis.

In an independent evaluation across live projects at Certara, automation in Nested Knowledge reduced workload by an average of 85% in key review steps, while maintaining or surpassing human-level accuracy. — Grys et al., AI in Evidence Synthesis: Have We Reached the Promised Land or Are We Still Wandering the Desert?

Why teams choose Nested Knowledge #

Cut review time without cutting corners. AutoLit® compresses search, screening, tagging, extraction, and critical appraisal into a single connected workflow. Every step that can be automated has an AI-assisted option; every AI output is traceable to its source and reviewable by a human before it becomes part of your review.

  • 85% average workload reduction in independent third-party evaluation: Certara’s ISPOR Europe 2025 evaluation across live projects found automation in Nested Knowledge cut workload by an average of 85% in key review steps. Criteria-Based Screening saved ~80% of time at ~95% accuracy; Adaptive Smart Tags extracted structured data at 90–100% accuracy with 80–90% time savings; automated critical appraisal saved ~100 hours in a single 280-study project. See Validation Studies of AI Tools in Nested Knowledge for the full breakdown, and Artificial Intelligence in Nested Knowledge for the feature inventory behind it.
  • RAISE-aligned by design: Our AI features map against Cochrane’s RAISE recommendations for responsible AI in evidence synthesis: traceability on every AI output, in-review validation, hybrid rule-based and LLM approaches where appropriate, and human oversight at every decision point. Learn more about how Nested Knowledge is aligned with RAISE here.
  • Independently validated: Every Smart tool ships with published or in-house validation data, and the Certara evaluation above provides third-party benchmarking against manual methods. Per-model accuracy, sensitivity, and specificity metrics are available on each model card.
  • Human oversight: Single or dual screening, dual critical appraisal, and full audit trails are built in. AI accelerates the workflow; reviewers make every final call.
