Contract review to tracked-change redlines
Clause-by-clause review with severity flags; suggested edits apply as native tracked changes you can accept or reject.
Microsoft Word add-in
LexBharat for Word
Statute and regulation lookup grounded in the US primary law corpus, inside Microsoft Word. No copy-paste into a separate tab: ask in the task pane and get an answer with checkable citations.
What it does in Word
Everything happens on the file you have open, and applies as native Word changes. Every answer carries checkable sources.
Playbook-driven review
Run your team's playbook against a draft; each redline carries a severity, a reason and a fallback.
Drafting from a brief
Generate a first draft from a plain-English brief, or turn an instruction into a tracked-change edit.
Case-law and statute research
Ask a legal question in the task pane and get an answer with checkable citations.
Defined terms, figures and cross-references
Catch undefined terms, inconsistent numbers and broken cross-references before the document leaves your desk.
Compare and finalize
Redline two versions with real tracked changes and run a final quality check.
