// why choose ReadMark
Automatic Reading Position Saving
ReadMark's core feature — it remembers exactly where you stopped on every page. No manual action needed. Liner has no equivalent; it focuses on highlighting, not reading progress.
One-Click Resume
Return to any article and instantly jump back to your last reading position. Perfect for long-form articles, documentation, and research papers you read over multiple sessions.
Local-First & Private
Reading positions stay in your browser; bookmarks sync through Chrome's own account. No ReadMark account, no third-party server, no tracking. Liner requires a Liner account and sends your data to their servers.
Lightweight & Fast
ReadMark is a tiny, focused extension that won't slow down your browser. Liner's AI features add significant overhead to every page load.
Half the Monthly Price
ReadMark Pro is $4.99/month. Liner Premium costs $9.99/month — roughly double. For reading position tracking without the AI research suite, ReadMark covers the core job at about half the cost.

AI-Powered Highlighting & Summary
Liner offers ChatGPT-powered summaries for web pages, PDFs, and YouTube videos — a completely different workflow for research-heavy users.
Cross-Platform Sync
Cloud-based storage means your highlights sync across devices. Useful if you work on multiple computers.
Large User Community
300K+ Chrome users and 10M+ total users provide strong social proof and a mature product ecosystem.
PDF & YouTube Support
Liner works across web pages, PDFs, and YouTube, making it a multi-format research tool.
// verdict
ReadMark and Liner solve fundamentally different problems. If you need to save your reading position and pick up long articles where you left off, ReadMark is the only choice — Liner simply doesn't offer this. ReadMark is also lighter, more private, and far cheaper. However, if you need AI-powered highlighting, PDF annotation, and YouTube summaries, Liner covers those use cases. Many users install both: ReadMark for reading progress tracking and Liner (or a simpler highlighter) for annotation.
// faq
Can Liner save my reading position like ReadMark?
No. Liner focuses on highlighting and AI summaries. It has no feature to remember where you stopped reading on a page. ReadMark is purpose-built for this — it automatically saves your scroll position and lets you resume with one click.
Is ReadMark really free?
Yes. ReadMark's core features — automatic position saving, one-click resume, and multi-page tracking — are completely free, up to 10 bookmarks. The optional Pro upgrade ($4.99/month) adds unlimited bookmarks and advanced features like custom markers and export.
Can I use ReadMark and Liner together?
Absolutely. They serve different purposes and don't conflict. Use ReadMark to track your reading progress and Liner (or any highlighter) to annotate and highlight text.
Does ReadMark work on long documentation sites?
Yes. ReadMark works on any web page — technical docs, blog posts, news articles, online novels, and research papers. It tracks each URL separately, so you can maintain reading positions across hundreds of pages.
Why would I choose ReadMark over Liner if Liner has more features?
More features isn't always better. Liner's AI tools add bloat, require an account, and cost $9.99/month. If your main need is 'remember where I stopped reading,' ReadMark does that perfectly with zero setup, zero accounts, and zero recurring fees — all while keeping your data private and local.
