简介
Never lose your browser context again.
ContextSnap saves your entire browser state and restores it exactly where you left off.
Not just tabs — your scroll positions, filled-in forms, selected text, and even pinned
tabs are all preserved.
What Gets Saved
- All open tabs (URLs, titles, pinned state)
- Scroll positions on every page
- Form inputs — text fields, dropdowns, checkboxes, radio buttons
- Text selections and highlighted text
- Active tab state
What Makes It Different
Most session managers only save your tabs. ContextSnap goes further — it captures the full state of every page and restores it faithfully.
Progressive Scroll — Infinite-scroll pages like YouTube, Twitter, and Reddit don't load all their content at once. ContextSnap automatically scrolls down to trigger lazy loading before restoring your exact position.
Smart Form Restore — Works with modern web apps built with React, Vue, and Angular. Handles dynamic form IDs that change on every page load (common on job application platforms like Greenhouse, Ashby, and Lever).
Open in New Window — Restored tabs open in a fresh window by default, so your current tabs stay untouched.
Who It's For
- Researchers — Save your research session with dozens of tabs, each scrolled to the relevant section, with key passages highlighted.
- Job seekers — Halfway through a long application? Save your progress and come back later without re-filling every field.
- Developers — Debugging across multiple docs, Stack Overflow pages, and GitHub PRs? Save the whole context and restore it when you switch tasks.
- Students — Working on a paper with multiple sources open? Save your reading context with scroll positions and text selections intact.
Settings
- Restore scroll position — on/off
- Progressive scroll — on/off (auto-scroll on infinite-scroll pages)

Privacy First
- All data stays on your device using local storage
- No accounts, no servers, no analytics, no tracking
- No data ever leaves your browser
- Password fields, hidden fields, and file uploads are never captured
Your browsing data is yours. Period.
