An evidence engine that reads the production like an investigator.
CloseVector is built to read a production the way an investigator would — surfacing supporting evidence, bad facts, key witnesses, the timeline, and privilege candidates — while keeping matter content on firm-controlled infrastructure and producing a defensible methodology record. Two layers. One integrated engine.
Investigative · Verified · Auditable · Yours
Built to Surface the Evidence, Including the Oblique
CloseVector is built to surface the evidence by meaning, not just by keyword. It processes briefs, memos, emails, correspondence, contracts, research, and discovery productions — building a semantic index designed to surface the oblique, coded, and fragmented evidence keyword search often misses.
Keyword Search
Search "non-compete" → only returns documents containing that exact phrase.
CloseVector
Search "can we enforce a client's employment restrictions?" → surfaces relevant documents even when they use different terminology.
Natural language queries across your entire document corpus
Multi-format indexing: PDF, DOCX, email, plain text, and more
Document relationship mapping: graph-based linking identifies semantic connections
Multi-stage retrieval pipeline: documents processed through multiple ranking passes
No per-query limits: unlimited searches for everyone in the firm
Every Result Comes With a Defensible Record
This is where CloseVector separates from most tools on the market. Every result comes with a complete, documented record of methodology — the evidence, and how it was found.
Cryptographic document hashing: verification of document integrity at time of indexing
Complete audit trail: every query logged with what was retrieved, scores, and exclusions
Relevance scoring: transparent ranking so you understand how results were evaluated
Document relationship mapping: graph-based linking identifies connections between documents
Documented methodology: complete search process documentation available for review
Exclusion logging: records what was searched, what was not returned, and why
Important: CloseVector surfaces candidates and logs methodology. Your attorneys remain responsible for privilege, responsiveness, and filings.
Generic AI Search vs. CloseVector Evidence Investigation
Generic AI Search
Returns "relevant" documents with no relevance scoring methodology
No record of what was searched or what was missed
Chunking can split critical passages across segments, losing matches silently
No document integrity verification
No automated relationship mapping between documents
"We searched" is the only defense
CloseVector Evidence Investigation
Multi-stage pipeline with transparent relevance scoring
Cryptographic hashing verifies document integrity
Complete audit trail: queries, retrievals, scores, exclusions
Graph-based document relationship mapping
Designed to support malpractice carrier and internal review
Defensible search record for discovery and litigation support
A Local Knowledge Layer With an API
CloseVector provides a verified, indexed, locally controlled knowledge layer with a local API. Where a firm feeds retrieval into downstream tools or automation, the same verified methodology and complete audit trail apply — so what those tools rely on is defensible, not a black box.
Retrieval that feeds a downstream tool carries the same verified methodology and complete audit trail — so the output is something you can stand behind, not a black box.
