An AI memory layer that resurfaces your research when it matters
Capture web pages, PDFs, videos, reports and LLM chats while you browse, then annotate them with your own notes and context.
Instead of waiting for a search, Liminary surfaces the relevant saved material while you write and inside meetings.
A meeting companion that pulls in the right information at the right moment, then saves the summary, full transcript and your notes for later recall.
Every answer points back to where it came from, internal or external, so you can verify claims rather than trust a black box.

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.
