Ask questions about the open document, draft clauses, rewrite passages and apply edits directly — with the full document as context.


Find language, terminology, definition, numbering and cross-reference issues, then apply clean corrections without changing the legal meaning.


Work across up to 1,000 documents as one shared context. Ask questions, compare clauses and review entire projects without rebuilding context.


Identify risks from each party’s perspective, prioritized by severity and paired with drafting suggestions you can apply directly in Word.


Compare every contract against your playbook or preferred standard, measure alignment and close missing or deviating clauses.


Research law across DACH with more than 1.8 million decisions and other sources, with structured answers and links to trusted sources.


Analyze hundreds of documents in parallel, extract the fields you define and turn the results into a structured table ready for Excel.
