Overview
Description

MAIGON is an AI-powered contract review platform that automates and accelerates the legal review process. The platform helps legal teams generate updated contract drafts from review recommendations, use agent-assisted workflows to summarize obligations and explain redlines, and select from a range of AI models for each review. It also offers cloud document imports, dashboard and table views for managing review history, and an integrated workspace for extracting, editing, and gaining insights from contracts. MAIGON is currently transitioning from its legacy site (maigon.io) to a new and improved experience at maigon.ai, with existing customer sign-in still available on the legacy domain.

Sirion is an AI-native contract lifecycle management platform used by large enterprises like Vodafone, IBM, and Morgan Stanley to create, manage, and analyze commercial contracts. Its AI engine, built organically over 15+ years rather than bolted on from a third party, centralizes contract data into a searchable repository and supports conversational search across an organization's full contract portfolio.
