PageOne is a Chrome add-on developed by migichen that aims to help users stay focused and organized during web browsing. It collects and organizes your browsing history into annotable, portable, topic-based tree lists in Markdown format. With PageOne, you can easily track and jump among links within a single tab, avoiding the clutter of multiple tabs.

One of the main features of PageOne is its ability to remind you of the topic you set up before browsing or searching. This helps you stay focused on your intended topic and avoid getting distracted by irrelevant links on a web page. Additionally, you can annotate links on the organized browsing history list and export them to free Joplin notebooks as markdown.

Using PageOne is simple. Just find the PageOne light bulb icon on the browser extension toolbar and click it. In the popup, input your topic or idea, or alternatively, open a new tab to show the same PageOne page. Start searching or browsing under the topic by clicking the Google button. You can always check back on the browsing history tree by clicking the light bulb icon. From there, you can add notes or mark history items as done. For more advanced note-taking functions, you can sync with free Joplin notebooks.

PageOne offers several features to enhance your browsing experience. You can easily review your browsing history as a popup page by clicking the extension icon. The browsing dependency is traced and well-organized into tree lists, making it easy to navigate through your history. You can also set and switch between topics, allowing for efficient organization. Additionally, you can check items as done, star and highlight URLs, and take notes directly on the history list.

If you're looking for a way to stay focused and organized while browsing the web, PageOne is a great option. Its intuitive interface and useful features make it a valuable tool for managing your browsing history.
