Fukidashi by thundermiracle

Fukidashi turns any web page into something you can write on. Select text, highlight it in one of five colors, and attach a note — the next time you open the page, your highlights and notes are right where you left them. Connect Google Drive, and they follow you to every browser you connect.

"Fukidashi" is Japanese for speech bubble: hover over a highlight and your note pops up in one.

HOW IT WORKS
1. Select text on any page — a small toolbar appears.
2. Pick a color to highlight the selection, or choose "Add note" to write a memo.
3. Hover a highlight to read its note; click to pin the bubble open, edit, or delete.

FEATURES
• Five highlight colors — yellow, green, blue, pink and purple
• Notes come back — every annotation is stored per page and redrawn on your next visit, including single-page apps that change the URL without reloading
• Page overview — the popup lists the current page's notes in reading order; click one to scroll straight to it and open its bubble
• Your whole library — the popup's second tab collects every annotated page, grouped by site; jump back to any page, or straight to a single note
• Sync across browsers — connect Google Drive on the settings page and your notes turn up in every browser you connect, edits and deletions included
• Optional encryption — set a passphrase and your notes are encrypted on your device (AES-256-GCM) before they are sent to Drive
• Back up and export — save every note to one JSON file and read it back in later, or export Markdown for Notion or Obsidian
• Works with Google Translate — a page opened through Google Translate counts as the same page, so notes taken on either version share one list and highlights survive the translated text
• One switch to pause — turn highlights and bubbles off everywhere without touching your stored notes

PRIVATE BY DESIGN
• No account needed — until you connect Google Drive, your notes stay in your browser's local storage and never leave your device
• Sync is opt-in and goes to you — notes are kept in a hidden app folder in your own Google Drive that only Fukidashi can open; there is no server of ours in between, and the developer never sees them
• Encrypt them if you like — with a passphrase, your notes leave the device already encrypted
• No tracking, no analytics, no ads
• Permissions: "storage" to save your notes, "activeTab" so the popup can talk to the page you are on, "identity" to sign in to Google — only when you connect Drive — and "alarms" to pick up notes from your other browsers while sync is on

GOOD TO KNOW
• Sync needs a Google account, and each browser is connected on its own
• A forgotten passphrase cannot be recovered — keep it somewhere safe
• A browser that has not synced for more than 30 days can bring back notes deleted in the meantime
• Text inside iframes and inside a page's own shadow DOM cannot be annotated
• If a page rewrites the text a note was attached to, the highlight disappears until that text comes back; the note itself stays listed in the popup
• Deleting a note is immediate — there is no undo
