What makes the Web Historian browser extension unique.
Have you ever lost track of time online? Need to retrace your steps to re-find something? Are you curious how you use the web at different times of the day? Which sites lead you to other sites most often? How your use of a website changes over time? The answers to these questions and many more are locked in data that is already in your web browser. Unlock it with Web Historian.

Websites Visited

Where did the time go? This visualization shows the number of visits to a website as the circle size. This gives you a broad view of how much you use various websites.

Search Words

What am I looking for? In this visualization words used in multiple search terms are larger, which emphasizes the subjects you search for in more depth. Hovering over a words shows the search terms it was used in.


How did I get there? The network visualization shows your browsing path through the web. An arrow from one site to another indicates that you clicked on a link from the originating site to the destination. Your main starting points for web browsing will be at the center of your visualization.

Time Heatmap

When do I browse the web most? The Time Heatmap shows the hours of the day and days of the week. A square is darker when you browse the web more.

Data Table

Give me details! The data table displays each of your browsing records and puts you in control of each one, enabling fine grained management of your history.

About US

Built from the ground up for security and privacy
Information is power

Web Historian is a browser extension for Google Chrome that helps you visualize the web browsing history that is already on your computer in a way you’ve never seen before. You can see what you’ve been looking for online and how you navigate through the web using interactive visuals.

Many companies collect and analyze web browsing history for marketing and advertising purposes, but browsing history data has been less accessible to those who want to analyze their own web browsing behavior, and to researchers who study the social impact of the web. That is why Web Historian was created.

Web Historian is an open source project developed specifically to provide users with as much transparency and control over their own information as possible. When users install Web Historian they download a program that runs only on their computer, not online using client side JavaScript. Users can opt-in to donate their data and complete a survey about their media use after they install Web Historian and remove anything they want from their browsing history.
