AI-Powered eDiscovery Software

Rational Review is a cloud-native, AI-powered eDiscovery platform that covers the full EDRM workflow — identification, preservation, collection, processing, early case assessment, analytics, attorney review, redaction, and production. It handles email, Microsoft Teams, Slack, SMS, WhatsApp, native Office files, PDFs, and audio/video with transcription, all from a single browser-based interface.

Rational Review combines cloud-native architecture, transparent per-gigabyte pricing, and modern AI — including generative-AI document summarization, agentic workflow automation, and TAR 2.0 continuous active learning — without the per-seat minimums, long-term contracts, or hidden processing fees typical of other eDiscovery platforms.

Predictive coding, also called technology-assisted review (TAR), is a machine-learning workflow that uses attorney coding decisions to rank remaining documents by likely responsiveness. Rational Review supports both TAR 1.0 (simple passive learning) and TAR 2.0 continuous active learning (CAL), so the model retrains after every coding decision and surfaces the most relevant documents first.

TAR 1.0 trains a model once on a fixed seed set and then applies it to the remaining population — useful for stable, well-defined cases. TAR 2.0, or continuous active learning (CAL), keeps learning from every coding decision throughout review, which handles shifting issues, rolling collections, and investigations better. Rational Review includes both and defaults to CAL.

Generative AI in Rational Review summarizes long documents, extracts entities and key facts, drafts privilege descriptions, answers natural-language questions across a case, and powers an agentic AI that can run multi-step workflows like "identify privileged emails, redact them, and stage them for second-level review" without manual handoffs.

Yes. Rational Review maps directly to the EDRM — from information governance and legal hold through identification, preservation, collection, processing, analysis, review, and production/presentation. Each stage is auditable, chain-of-custody is preserved, and hand-offs between stages are tracked for defensibility.

Rational Review processes hundreds of file types including PST/OST/mbox email, Microsoft 365 and Google Workspace exports, Microsoft Teams and Slack archives, SMS/MMS and WhatsApp exports, Office documents, PDFs, CAD, source code, compressed containers, forensic images (E01/DD), and audio/video with automatic transcription.

Chat data is ingested with full fidelity — channels, DMs, threads, reactions, edits, attachments, and user metadata — and rendered in a native conversation viewer rather than flattened to email-style documents. Reviewers can redact individual messages, produce by conversation, day, or custodian, and export in standard load-file formats.

Early case assessment is the stage where legal teams cull, filter, and investigate data before full review to scope cost and strategy. Rational Review offers search, date/custodian/domain filtering, concept clustering, email threading, near-duplicate detection, and AI-assisted summaries so teams can eliminate non-responsive data — typically 60–80% of a collection — before paying to review it.

Attorney review is the single largest eDiscovery cost. Rational Review customers typically reduce reviewable volume by 40–60% through TAR 2.0 predictive coding, email threading, near-duplicate suppression, and concept clustering, and reduce per-document review time through AI summarization and in-line translation — driving total review cost reductions of 50% or more on typical matters.

Both. Rational Review is cloud-native and delivered as SaaS on segregated, SOC 2-aligned infrastructure, with each client environment logically isolated and regional data residency available. For government and regulated enterprise customers, on-premises and private-cloud deployments are offered through Rational Enterprise professional services.

Rational Review uses AES-256 encryption at rest and TLS 1.3 in transit, two-factor authentication, SSO/SAML, role-based access controls, complete access audit logs, and a 99.9% uptime SLA. The platform supports HIPAA, GDPR, CCPA, and government workflows, with SOC 2 Type II reports and FedRAMP-aligned deployment options available for enterprise customers.

Legal holds can be issued, tracked, acknowledged, and released directly from Rational Governance and pushed into Rational Review. Every action — ingestion, processing, coding, redaction, export — is captured in an immutable audit log with user, timestamp, and action detail to establish a defensible chain of custody.

Rational Review produces in all industry-standard formats: native files, near-native, TIFF/PDF images with Bates numbering and confidentiality endorsements, standard DAT/OPT load files, EDRM XML, and linked text/OCR. Redactions are burned in, privilege logs are auto-generated, and productions are QC-checked before export.

Yes. Reviewers can apply manual, search-based, and AI-suggested redactions across text, images, and transcripts, including automatic PII/PHI detection. Privilege review is supported with configurable privilege tags, AI-suggested privilege calls, and automatic privilege-log generation in standard formats.

Rational Governance handles information governance, data mapping, retention, and legal hold across enterprise data sources. When a matter begins, in-place indexes and custodian data can be pushed directly into Rational Review — eliminating duplicate collection, shortening time-to-review, and preserving a single chain of custody from source system to production.

Rational Review uses transparent per-gigabyte pricing with no user-seat minimums, no separate processing fees, and predictable monthly billing. Pricing scales with data volume in the platform, not with reviewer headcount, so adding contract reviewers during a review surge does not increase platform cost.

Rational Review is used by law firms of every size, corporate legal departments, government agencies, and regulated industries including financial services, healthcare, insurance, and energy — for litigation, internal investigations, regulatory response, second requests, FOIA, and compliance matters.
