From early case assessment to final production.
Rational Review helps law firms, government agencies, military contractors, and in-house legal teams review evidence and prepare productions. Search email, messages, and documents, apply redactions, and use predictive coding and AI-assisted review to prioritize work.
Search by custodian, date, or keyword to see what is in your collection. Examine email threads, near duplicates, and related documents before setting the review scope. Keep that work in the same matter as coding, redaction, and production.
Connect preservation in Rational Governance to processing, case assessment, review, and production in Rational Review. These stages follow the Electronic Discovery Reference Model (EDRM).
Use Rational Governance to issue hold notices, track custodian acknowledgments, and preserve relevant records in place before collecting them for review.
Load email, documents, and chat exports with CloudStreamer. Extract text and metadata, identify duplicates, and organize email threads for searching and review.
Search the collection, examine communication patterns, and compare search term hits. Use date and custodian filters, clusters, and near duplicates to define the review scope.
Assign review queues, code documents, and apply redactions. Use AI Review Assist and predictive coding to prioritize documents, then check the results against your review protocol.
Select documents for production, apply Bates numbers and confidentiality markings, and export images, native files, and load files. Check imaging in the Production Wizard before final output.
Reduce manual document review with AI-assisted relevance decisions, predictive coding, and document summaries. Define the criteria for your matter, examine the results, and decide which documents need closer review.
AI Review Assist explains each responsiveness decision and routes low-confidence calls and coding disagreements for human review. Matter Agent lets you request searches, coding, and other matter tasks in plain language, with a record of its actions. Read product updates and release notes.
Apply your relevance criteria to a collection. Each document receives a decision, confidence score, and explanation. Check uncertain calls in the Needs Human Review queue.
Request searches, coding changes, review queues, and production tasks in plain language. Follow the action log as it works and confirm bulk changes before they run.
Ask questions about a document or the matter. Follow up in the same conversation to explore a point in more detail.
Generate summaries for a group of documents. Use them to identify facts and select files for closer reading.
Score communications as positive, negative, or neutral. Use those scores to sort material and investigate patterns in a collection.
Use reviewer coding decisions to rank unreviewed documents by likely relevance. Check the predictions against your review criteria as the model learns.
Write descriptions of loaded images into the Summary coding field so reviewers can search for their content.
Question AI personas using the knowledge bases assigned to them. Compare responses while exploring investigation questions by text, audio, or video.
Translate document batches and search the translated text. The in-house model supports 28+ languages, including Polish, Gujarati, and Latvian, with no usage charge.
Provide the relevance criteria for your matter through a case file, guided chat, or criteria form. AI Review Assist applies those criteria to the document collection.
Use plain-language instructions to request searches, document coding, review queues, and production tasks in a chat session.
Ask investigation questions of AI personas by text, audio, or video. Each persona uses the knowledge bases associated with it.
Track review progress and examine the collection from matter dashboards. Select the panels and charts you need for early case assessment, queue monitoring, and project reporting.
Examine document relationships before assigning full review. Built-in analytics help reviewers identify repeated content and follow related communications.
Build a query in the visual search builder and watch result counts update. Open document previews to examine hits, then take random samples for quality checks.
Train relevance predictions from decisions your reviewers make. Rational Review ranks remaining documents by likely relevance, and TAR 2.0 updates those predictions as coding continues. Use your review protocol to check the results and decide when further review is needed.
Start with coding templates, then set up queues and coding views for the matter.
Set access by user role, document, and coding field. Reuse built-in roles or define custom roles for the matter so different parties can work with the material they are permitted to see.
