Public libraries have always been where communities go to learn something new without being sold to, surveilled, or judged. AI should be no different — but most AI tools were not designed with a library's values in mind.
That is the gap PLAID3 Hub was built to close.
One platform, three audiences
PLAID3 Hub is a single platform that serves everyone in the building.
For patrons, it is a guided AI chat with a live coaching panel that suggests better questions in real time — plus a self-paced curriculum, "11 Things You Should Know About AI," with interactive exercises along the way. No account, no app, no personal information.
For librarians, it is near-zero overhead. The literacy program needs no staff facilitation, blocked queries route patrons to a librarian instead of a dead end, and access codes get you running on day one.
For the board, it is an admin dashboard that speaks board-meeting language: anonymized, aggregate usage statistics and a one-click PDF report.
Privacy is the point
The thing we are proudest of is what PLAID3 Hub does not do.
Nothing to breach, because nothing is collected.
Conversations are not stored. Patron sessions are never surveilled. There are no patron accounts, because we never collect identifying information in the first place. Library staff see aggregate numbers — never who asked what.
Live in a day
Because there is no IT integration required to launch, most libraries are up and running within a day. Access codes are all a patron needs; SIP2 and IP-based authentication are on the roadmap for libraries that want tighter integration later.
The base subscription is $1,500 per year per library system, with learner packs available as your reach grows.
