DISCO
enterpriseCloud eDiscovery platform for legal data processing, review, analysis, and production.
API-driven pipeline orchestration that ties ingestion, processing stages, and export into repeatable job workflows.
DISCO’s core processing pipeline turns raw collections into review-ready artifacts by running file normalization, email threading, text extraction, and OCR for scanned images when enabled. Its automation approach supports rerunnable configurations so the same processing steps can be applied consistently across related loads. Operationally, DISCO manages large volumes by separating processing stages such as extraction, deduplication, and similarity analysis so downstream steps can consume stable outputs.
A key tradeoff is that advanced automation and integration require deliberate pipeline configuration rather than click-only setup. DISCO fits best when a team needs consistent processing across multiple productions or review sets and wants the processing job record to map cleanly to change control and audit needs.
- +Configurable processing pipelines with rerunnable job definitions
- +Strong near-duplicate analysis output for large document populations
- +End-to-end transformation into review-ready formats
- +API-driven automation supports repeatable ingestion and export steps
- –Advanced workflows require careful upfront configuration discipline

Reveal
enterpriseAI-assisted eDiscovery software for data processing, review, analysis, and production.
API-controlled processing jobs that provide end-to-end orchestration signals for pipeline monitoring and automation.
Reveal fits teams that need repeatable processing steps for email and documents, then want consistent outputs for review sets and production set creation. It handles parsing, metadata extraction, text extraction, and common evidence normalization steps that reduce variability between custodians and collections. Automation support is stronger than basic desktop-style processing, because Reveal exposes job execution control and status through an API surface. The result is lower operator variance when the same processing recipe must run across multiple matters.
A tradeoff is that deeper customization of parsing behavior and output mapping requires configuration discipline and testing on representative sample sets. Reveal works best when a legal operations team can standardize processing recipes per matter type and enforce consistent outputs for privilege review, redaction, and production set builds. It can feel slower to adopt when a project requires ad hoc, one-off transforms without a repeatable pipeline definition.
- +Consistent processing outputs for native file review and downstream production work
- +API-driven job control supports orchestration across multiple matters
- +RBAC and auditable job activity help enforce access boundaries
- +Configurable processing steps reduce operator variability across teams
