StudyEaseHaven

Core value proposition:
*Turns any webpage into something you can highlight and take structured notes on — not just PDFs, the whole open web
*Five distinct note-taking methods: Outline, Cornell, Boxing, Q&A, and Slip-box (Zettelkasten-style)
*Collections let you pool highlights from many different websites into one organized notebook
*Highlights persist: come back to a page you've marked up before, and it re-appears highlighted automatically when you run the extension
*Live-linked to the full StudyEaseHaven web app — same notes, same data, edit from either place

Key features
*One-click toggle per tab — nothing runs on a page until you explicitly turn it on
*Tap any existing highlight to recolor it, re-select different text, or delete it, right on the page
*Outline method supports nested headings and attaching notes as sub-notes of one another
*Cornell method includes a real summary composer — select multiple notes, write a synthesized summary
*Boxing method supports typed relationships between boxes (sequential, hierarchical, causal, comparative, conditional)
*Slip-box method generates genuine Luhmann-style hierarchical IDs, supports filing one note behind another, keywords, and cross-references, with an auto-built index

Privacy and permissions
*No account, no sign-up, no cost
*No data ever leaves your browser — everything is stored locally via the browser's own storage APIs
*No analytics, no tracking, no third-party requests
*Only requests activeTab (access only to the tab you're on, only after you click the icon) and storage (to save your notes)

Technical details
*Built on Manifest V3, the current Chrome extension platform
*No remote code execution — everything runs from code bundled in the extension itself
*Syncing with studyeasehaven.ca happens through Chrome's own secure messaging between the extension and the specific site — not through an external server

Good to know
*Highlight restoration depends on the page's text still matching what you originally selected — if a page's content changes, that specific highlight may not visually reappear (your note itself is never lost)
*Currently supports Chrome and other Chromium-based browsers (Edge, Brave, etc.)
