Visualize your web use to understand your habits

Our focus

Take control of how you use the web

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

Information is power

Web browsers keep history data, but they don't enable users to benefit from this data to understand their own habits. Web historian is a browser extension that helps users see their web browsing patterns using interactive visualizations. Users can harness this information to make informed decisions about their web use.

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.

Many companies collect and analyze web browsing history for marketing and advertising purposes. 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 a non-profit 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. Users can opt-in to a research study after they install Web Historian and remove anything they want from their browsing history.

Take control of how you use the web with Web Historian.
