1

Ingest

HyperDocs ingests legacy source code to systematically understand and reconstruct institutional logic.

2

Synthesize

Docs are updated automatically as changes are committed to the codebase, synthesizing with existing information.

3

Query

Your docs become searchable and queryable across the entire organization.

HyperDocs platform interface

HyperDocs surfacing structured documentation from legacy source code.

Engineered for industrial-scale complexity.

Frontier-Class Reasoning

Beyond simple reasoning, our orchestrator performs multi-stage analysis to reconstruct complex system logic.

Frontier-Class Reasoning

Semantic Extraction

Parses code into hierarchical units, tracking relationships, entities, and objects.

Agentic Orchestration

Multi-stage pipeline with real-time progress tracking and automated MDX validation.

End-to-end Support

Native support for the full mainframe stack: COBOL, PL/I, JCL, and Assembler.

Acts as a System of Record

A single source of truth that simultaneously generates technical documentation for developers and plain-English business rules for analysts.

Business Rule Proofs

Directly link business requirements to specific code snippets with line-level highlighting.

Perspective Rendering

Tailor documentation depth and language for developers, BAs, or auditors automatically.

Interactive Explorer

Real-time browsable interface with semantic search across all extracted code units.

Built-in Verifiability

Establish provable connections between requirements and implementation with line-level code proofs and automated data lineage.
