Wikitrail

Ever opened Wikipedia to check one thing and surfaced an hour later knowing everything about the Byzantine economy? WikiTrail maps exactly how you got there.

WikiTrail runs quietly in the background while you browse Wikipedia, recording every article you visit in order. Open the extension at any time to see your trail as an interactive graph — nodes sized by time spent, branches showing where you backtracked and went a different direction. The deeper the rabbit hole, the more interesting the map.

Visualize your trail - Switch between a force-directed network graph showing how articles connect, and a chronological timeline showing every visit in order — including revisits.

Save notes as you go - Highlight any text on a Wikipedia page, right-click, and choose "Save to current trail node". The note is saved to that article and links directly back to the highlighted passage so you can find it again instantly.

Search everything - One search panel queries across every note you've ever saved, across every trail, with results linked back to the original article and session.

Name and tag your sessions - When you end a trail, give it a name, a research question, and tags. Your history becomes a searchable archive of how you've thought about topics over time, not just a list of dates.

Export your research - Export any trail as a self-contained interactive HTML file or a clean Markdown document — complete with the article list, time spent on each article, all your saved notes, and an embedded interactive graph. Drop the markdown straight into Obsidian, Notion, or any notes app.

Multiple tabs, no interference - Each Wikipedia tab tracks its own independent trail. Two research sessions running at once never conflict.

WikiTrail is free, open source, and stores everything locally on your device. No account, no sync, no data leaves your browser.
