QuoteHarbor: keep the quote and its source

Found a sentence you want to remember, but lose the source when you copy it? I built QuoteHarbor to preview your selected passage and save it with the page title and URL.

Search and edit your local library later, add optional notes and tags, or export Markdown and JSON backups. No account, ads or analytics. It saves only after you click Save and does not create verified academic citations or cloud sync.

I am the developer. Feedback on your experience and confusing steps is welcome.

How it works

Capture happens when the user invokes the extension. The activeTab permission grants temporary access to the current page, while scripting reads the selected text in the top frame for a preview. Saving requires an explicit click; there is no background scanning.

The local library contains:

• the quote, optional notes and tags
• source title and URL
• timestamps

Search, editing, Markdown export and JSON backups make the saved material reusable without a cloud account.

Browser restrictions still matter

Some pages, embedded frames and PDF viewers do not allow capture; manual paste is the fallback. Attaching a source URL helps preserve provenance, but it does not produce a verified academic citation.

Try the workflow

The walkthrough uses fictional data. FocusPet's completion demonstration is accelerated; the LeetHub demonstration simulates upload responses and does not perform a live GitHub write.
