# Hypercubic

> Agentic AI for mainframe operations and modernization. Hypercubic helps banks,
> insurers, governments and airlines that run IBM z/OS mainframes preserve
> institutional knowledge, document COBOL, operate legacy systems safely, and
> modernize to modern architectures with formal verification. Deployed inside the
> customer's own VPC or on-premise, with zero data egress and no model training
> on customer data.

## Products

- [HyperDocs](https://www.hypercubic.ai/hyperdocs): Auto-updating documentation engine. Reads COBOL,
  PL/I, JCL and Assembler source, reconstructs business logic, and keeps
  documentation in sync as code changes.
- [HyperTwin](https://www.hypercubic.ai/hypertwin): Tribal knowledge capture. Runs AI-led interviews
  with retiring subject-matter experts and turns how they navigate COBOL, JCL and
  CICS into a searchable, audit-ready expert model.
- [Hopper](https://www.hypercubic.ai/hopper): Desktop AI agent for z/OS engineers, free Hobby tier.
  Bundles a TN3270 terminal, datasets browser, jobs browser and an AI agent that
  reads COBOL/JCL, submits and monitors batch jobs, decodes VSAM records and
  drives ISPF from plain-English prompts. Runs on macOS, Windows and Linux; needs
  nothing installed on the mainframe.
- [HyperLoop](https://www.hypercubic.ai/hyperloop): Verification-driven modernization. Moves mainframe
  workloads to cloud with line-level formal correctness proofs and behavioral
  equivalence verification against the legacy system.
- [Platform overview](https://www.hypercubic.ai/platform): How the four products work together across
  discover, preserve, operate and transform.
