AI writing assistant with autocomplete, research, and a Chrome extension
Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
Turn a few keywords into a complete, ready-to-send email reply without switching tabs.

Legal research and citation linking, built into your browser
The extension scans the page you are reading and turns case names, citations and statutory references into clickable links that open the matching document on vLex.com, so you can verify authority without leaving your tab.
Vincent AI reads the context of the content in front of you and recommends relevant vLex cases, statutes and commentary, letting you explore the surrounding legal landscape in one click.
Search results are augmented with related vLex documents, so case law, legislation and secondary sources appear beside ordinary web results instead of being buried several pages deep.
Beyond the extension, Vincent AI accepts natural-language legal questions and returns structured answers with linked citations, and can generate multi-jurisdiction surveys for comparative work.
