The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.

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.
