HistoryAnalyzer

A Python script to grab some tasty data from your Chrome's history and analyze it.

Setup

python3 -m venv venv
source venv/bin/activate   # Windows: venv\Scripts\activate
pip install matplotlib

Usage

Close Chrome first — it locks the history database while running.

python3 HistoryAnalyzer.py

The script copies your Chrome profile's History database to a temp folder, tallies visits per domain, and sorts them from most to least visited. You'll then be prompted to choose one of:

Command	Description
c	Print the list to the console.
p	Show a horizontal bar chart of the list.
s	Save the full sorted list to history_by_site.csv in the current directory.

Notes

• No data leaves your machine.
• Chrome retains roughly 90 days of history (or ~10,000 entries).
• Only reads the current user's own Chrome profile.
• Works cross-platform: Windows, macOS, and Linux, using each OS's default Chrome profile location.
