Counsel's Notebook: A cross-case research journal. Save passages from multiple cases, organize with tags, and use AI to synthesize connections across entries. Argument Builder: Build structured issue trees, collect passages as evidence, and use AI to draft persuasive argument paragraphs backed by the case text. Compare Cases: Paste a second CanLII URL to generate a detailed comparison of facts, issues, reasoning, and holdings between two decisions. Similar Cases: Discover related decisions automatically. Gist: Select any text on the page for an instant plain-language summary. Also available via right-click. Bookmarks: Save any AI response for later reference.
