Knowledge Engine
ProAI reads everything you write and builds a living knowledge base, finding connections, flagging contradictions, and keeping running summaries.

You put things in, and nothing comes back unless you dig. Notes sit in silos. Knowledge stays fragmented. The more you write, the harder it gets to find what matters.
The Knowledge Engine reads everything you write across every notebook. It identifies people, projects, and topics, then creates living pages that stay up to date as you write more.

Sarah, account manager
Sarah has 12 notes about Client X scattered across notebooks. Before her meeting, the Knowledge Engine already has a Client X page with a timeline of decisions, open action items, and key contacts, ready to go.
David, researcher
David is writing about AI in healthcare. The Engine spots a gap in mental health coverage and flags contradictory FDA timelines across two different notes he wrote months apart.
Mia, consultant
Mia juggles 4 client engagements. The Engine maintains a living page per client with every decision, pending item, and scope change, across all her notebooks.
Alex, engineering lead
Alex clips management articles and engineering deep-dives into separate notebooks. The Engine surfaces unexpected patterns between leadership strategies and technical decisions.
Your knowledge pages travel with you. Review entity summaries, spot gaps, and prep for meetings right from your phone.

Other apps bolt AI on top. Cimanote builds understanding from the ground up.
