The histre extension beside a Wired article: a sentence is highlighted in yellow, and the sidebar holds a note with tags, a small table of facts and a list of collections to file it in

Highlights and notes, right on the page

Select text on any site and keep it, in several colors. Write a note in the extension while you read, tag it, add a few facts in a table, and file it in a collection. Everything links back to the exact spot on the page.

More about highlights

Ask AI about the page you are on

Open the sidebar on any page and ask a question about it. The answer comes from the page's own text, so it sticks to what you are actually reading, and one click keeps it as a note.

History as a tree, not a list

The extension keeps the pages you visit, with titles and time spent, and lays them out the way you found them: the search, the tabs you opened from it, and the one you stayed on. Fold a day away, or search it alongside your notes. Pause it any time. Private windows are never recorded. More about tree-style history.

Research on the web is a loop. histre has a part for each turn of it.

Explore

Read widely and let histre keep the trail. The pages you visit become a tree, and anything worth keeping gets a highlight or a note on the spot.

Tree-style history

Filter

Narrow it to what matters. Search everything you kept by what the pages said, not only their titles, and sort the keepers into collections.

Deep search

Decide

Line up the finalists. Pull the facts off each page into a table, compare them side by side, and share the collection with whoever decides with you.

Built for keyboards and screen readers

The web app and the extension are developed and tested with NVDA and Orca by our head of engineering, who is blind. Every screen works without a mouse, and a command palette puts saving, searching and note-taking two keystrokes away.
