Know what's true
about every project.
Pull your READMEs, notes and project pages into one searchable library. See who owns each piece of work, record claims and hand-offs, and check every status against its evidence, so nothing is reported done without proof. Free, and it never leaves your browser.

Status you can prove.
Project knowledge drifts: the README says one thing, the tracker another, and the person who knew has moved on. KnowledgeOS keeps the pages, the owners and the evidence together and tells you where they disagree.

Every page, found in a keystroke.
Drop in Markdown or text files and search them all with relevance ranking, highlighted matches and tags. README lines such as Status and Owner feed the work registry automatically.
Claims and hand-offs
One owner per piece of work. Claiming work someone else holds is refused; hand-offs need a note on what is done and what is next.
Evidence reconciliation
Done without a link, stale claims, overdue dates, blocked without a reason, duplicates and READMEs that disagree with the registry are all flagged.
Status report in one click
Export a Markdown status report, a CSV of the registry or the whole workspace to share or reopen later.
Your team's memory.
A fictional studio is loaded so you can explore. Import your own pages; everything saves automatically in this browser only.
