From reading to a record you own

You read something worth keeping. Usually it ends up as a screenshot, a bookmark, or a paste with no source, and your AI has no idea what was yours and what was the author's.

Praxamark keeps it properly. You highlight what matters, each colour carrying a meaning you choose. You add your own thoughts. Praxamark posts it to the places you keep things, such as your notes, your AI twin and Tinderbox, with its source, whose words are whose, and a provenance record that says where every word came from and how it may be used.

1HighlightSelect a passage in the article. A bar appears: pick what it is, a Quote, a Statistic, an Idea or a Question.
2Add a noteYour own words, kept apart from the author's.
3Project and fieldsSay what it's for. The project brings its own fields and values.
4Post, and seeSee the post with its header, the provenance record, and each place's receipt.

The library is becoming your data steward

By Mara Lindqvist · 12 October 2026 · a pretend article, written for this simulation

Select any passage to highlight it.

For most of their history, public libraries have lent things: books, then films, then laptops and hotspots. A quieter change is under way. Libraries are starting to look after something more personal on their patrons' behalf: their data.

In a survey of 412 public libraries this year, 61% said patrons had asked staff for help understanding what an app or website collects about them, up from 23% three years earlier. Fewer than one in five said they had a program in place to answer.

“We already protect what you borrow,” said Ruth Abernathy, who directs a county library system in Oregon. “Nobody can find out what you read here. People are asking why the rest of their life doesn’t work that way.”

Some libraries now run workshops on personal data stores, where a person keeps their own records and lends them out on their own terms. Others help patrons send data access requests, and keep the replies.

The idea is not new. What is new is the tooling. Standards for terms that come from the person, and for records that prove where data came from, have arrived together. A library could be the place where a neighbourhood learns to use them.

Can a library be neutral and also take a side on privacy? Abernathy thinks it already does. “Privacy is the oldest service we offer,” she said.
