About Cecilia AI

Introduction

Cecilia AI is DISCO’s built-in AI fact expert for litigation and eDiscovery, combining Cecilia Q&A, single-document Q&A, document summaries, definitions, and deposition summaries inside the DISCO eDiscovery platform. In 2026, DISCO added an agentic, multi-step reasoning engine to Cecilia at no extra charge, aimed at producing more thorough, autonomous analysis of large document sets than earlier single-shot AI features.

Legal Research & Document Review

Cecilia’s document review features report up to 95% recall and 91% precision as measured by DISCO customers, with narrative explanations attached to each tagging decision for transparency during review QC. Cecilia Auto Review can process roughly 25,000 documents per hour from plain-English prompts, and its deposition summarization tool organizes witness testimony by chronology and topic to speed up case preparation.

Contract Analysis

Cecilia is built for litigation discovery rather than transactional contract review, but its document classification and near-duplicate/tagging tools can be applied to contracts and other documents pulled into a DISCO review.

Document Drafting

Document drafting is not Cecilia’s focus; it is oriented toward reviewing and summarizing existing material rather than generating new legal documents.

Legal Translation

Cecilia supports multilingual document review, helping teams tag and summarize foreign-language documents within a matter, though it is not marketed as a standalone legal-translation product.

Predictive Analytics

Cecilia does not provide litigation-outcome prediction; its analytics are focused on review progress, tagging consistency, and document relationships within the current matter.

Pricing

DISCO moved to a transparent per-GB pricing model on processed data with no ingest fees, and Cecilia AI is included at no additional cost on top of that. Total spend typically runs from roughly $20,000 to $100,000 per year depending on firm size and data volume, which is a meaningful simplification compared with older per-feature eDiscovery pricing.

User Reviews and Ratings

DISCO and Cecilia AI are well reviewed on G2, with users consistently praising the intuitive interface and efficient document management, including for teams with limited technical background. Some reviewers note that overall cost can still be high for smaller clients even with the simplified pricing model.

Verdict

Cecilia AI is a strong, well-integrated choice for litigation teams already using or considering DISCO for eDiscovery, particularly given the 2026 shift to simpler, all-inclusive pricing. It is not a general-purpose legal research or drafting tool, so firms without meaningful eDiscovery volume are unlikely to need it as a standalone product.
