CorpusAI releases 'BriefSuite' — summarization suite for legal teams

AI · 5 min read

CorpusAI, focused on legal-domain LLM applications, introduced BriefSuite today along with a $27 million Series A led by Meridian Capital. The package includes deposition summarization, statute extraction, and an automated brief-drafting assistant with citation checks linked to proprietary case databases.

BriefSuite uses a retrieval-augmented pipeline and a fine-tuned citation verifier trained on annotated legal corpora and court opinions. CorpusAI emphasized transparent chain-of-evidence features for compliance: each claim in a summary links back to source documents, timestamps, and confidence scores that lawyers can audit.

Law firms participating in pilot programs reported faster first drafts and improved research throughput, particularly for e-discovery and document-heavy litigation. CorpusAI plans integrations with common practice-management tools and a managed on-prem option for regulated customers next quarter.
