A Chrome extension that saves the current tab - URL, title, timestamp & notes to a Google Sheet with one click.

What it does

• Click toolbar icon → appends URL, title, and timestamp as a new row in your sheet.
• Select text → right-click → "Save to Marksheet with note" → saves the URL with your note. If the URL is already in the sheet, the note is appended to the existing row.
• Duplicate detection - local URL cache prevents double rows. Icon flashes blue if already saved.
• Multiple sheet configs - separate sheets for work, reading, research. Switch active config from the side panel.
• Flexible column mapping - map URL, title, and date to any column. Skip fields you don't need.
• Status feedback via icon tint: green (saved), blue (duplicate), red (error).

Built on

• Manifest V3 - Chrome 114+
• Google Sheets API only - spreadsheets scope. No Gmail, no Drive, no profile data.
• No backend. No telemetry. All config stored locally.
