PageNav is a free Chrome browser extension that adds floating navigation panels to text-heavy web pages and YouTube videos, letting users jump between sections and transcript timestamps instantly.
What is PageNav?
PageNav is a lightweight browser extension for Chrome that automatically scans a page's H1–H6 headings and generates a floating table of contents panel. On YouTube, it converts subtitles into a timestamped navigation sidebar. It processes all data locally in the browser, prioritizing user privacy. The extension is developed by the team at Aixien.
Key Features
- Smart heading scan – Automatically detects H1–H6 headings on any web page and builds a collapsible outline.
- Floating trigger – A thin vertical line on the right side of the page expands into the navigation panel on hover or click, without blocking content.
- Current section highlight – Tracks scroll position and highlights the active heading in the panel in real time.
- YouTube subtitle navigation – On YouTube video pages, the panel switches to a subtitle navigator with clickable timestamps for each caption segment.
- Theme switcher – Four built-in themes: Paper, Linen, Graphite, and Midnight.
- Keyboard navigation – Use J and K keys to move between headings without a mouse.
- Privacy-first – All analysis happens locally; no data is sent to external servers.
- Cross‑site support – Works on 12+ content platforms including Medium, documentation sites, blogs, and knowledge bases.
Who is it for?
- Long‑form readers – Anyone reading articles, documentation, or reports without built-in tables of contents can quickly see the structure and jump to relevant sections.
- YouTube learners – Students or researchers watching lecture videos or tutorials can use transcript timestamps to revisit specific parts without scrubbing.
- Documentation users – Developers and technical writers browsing API docs or help centers benefit from heading scanning on dynamic pages.
What can you do with PageNav?
- Navigate long articles – Open the panel to see the full heading hierarchy of a blog post or news article, then click any heading to jump there instantly.
- Follow video transcripts – On YouTube, use the timestamped subtitle list to skip to the exact moment a topic is discussed.
- Stay oriented while scrolling – The automatic highlight shows your current reading position, making it easy to resume after scrolling away.
- Customize reading environment – Switch between four themes to match your preference and reduce eye strain.
