Maigon
Maigon is a paid AI contract review platform for legal and commercial teams, available on the web and as a browser extension. Users can upload DOCX or PDF agreements to surface clauses, identify risks, answer questions, draft wording, and edit contracts with redlines. A sortable review dashboard organizes findings, while an assistant can summarize obligations, suggest fallback language, and explain redlines. Listed workflows cover NDAs, DPAs, consultancy agreements, privacy policies, product supply agreements, R&D agreements, and end-user licence agreements. Its DPA workflow checks GDPR and current EDPB guidance and extracts clauses, concepts, terms, risks, and recommendations. Privacy-document reviews assess statements against GDPR criteria. The Chrome extension reviews Google Docs and Drive files, showing compliance scores, severity-ranked issues, proposed tracked edits, summaries, and comment-thread findings. Content is sent for review only after selecting Review, and edits are applied only when a suggestion is accepted. Maigon says uploaded documents are processed for review and then deleted. Its output is informational, not legal advice.
