• ⏱️ Hands-free. Tracking starts when people appear in the call and saves automatically.
• 📋 Rosters. Paste or import your class or team list and see who is Present, Late, Too short or Absent, live in the call.
• 📊 Dashboard and analytics. Meeting history, per-person trends, recurring-meeting matrices, tags and notes.
• 📤 Exports. CSV, Excel, a branded PDF report (Bengali names render correctly), a mobile-friendly HTML report, JSON or copy as a table.
• 🔒 Private by design. Only the storage permission. No network requests, no analytics, no audio or video.
• 🌙 Comfortable. Dark mode, keyboard shortcuts, English and Bengali (বাংলা).

File names include the meeting date, e.g. meet-attendance_abc-defg-hij_2026-10-09_1400.xlsx. All encoders (ZIP, XLSX, PDF) are written from scratch and bundled; nothing is loaded from a CDN.

• Dark mode follows your system by default, or force light or dark. Applies to the in-Meet panel, popup and dashboard.
• Keyboard shortcuts via chrome.commands: Alt+Shift+M toggles the in-Meet panel, Alt+Shift+S saves now. Change them at chrome://extensions/shortcuts.
• Languages: English and Bengali (বাংলা) through chrome.i18n (extension/_locales). The UI follows the browser language.

Add Meet Attendance Tracker to Chrome →

1. Open the Chrome Web Store listing and click Add to Chrome.
2. Pin Meet Attendance Tracker from the puzzle-piece menu.
3. Join a call on meet.google.com. Attendance is recorded automatically.

Updates install automatically. This also works in Brave, Opera and other Chromium browsers, and in Edge (see below).

Use this to try a build before it reaches the store, or to test your own changes.

1. Download meet-attendance-tracker-vX.Y.Z.zip from the latest release and unzip it into a folder.
2. Open chrome://extensions (also works in Edge, Brave and other Chromium browsers, v110+).
3. Turn on Developer mode (top-right).
4. Click Load unpacked and select the unzipped folder (the one that contains manifest.json).
5. Pin Meet Attendance Tracker from the puzzle-piece menu.

To update, download the new zip, replace the folder's contents and click the reload icon on the extension card. Your data is kept, because it lives in the browser and not in the folder.

The easiest way is the Chrome Web Store listing: in Edge, click Allow extensions from other stores when prompted, then Get / Add to Chrome.

The release zip also works in Edge for development (tested with Edge 155; the full integration suite passes in Edge, see npm run test:edge):

1. Download and unzip the latest release as above.
2. Open edge://extensions.
3. Turn on Developer mode (the toggle in the left sidebar; on narrow windows it's under the ☰ menu).
4. Click Load unpacked and select the unzipped folder.
5. Click the puzzle-piece (Extensions) button in the toolbar and choose the eye icon (Show in toolbar) next to Meet Attendance Tracker.
6. Join a call on meet.google.com in Edge.

Notes for Edge:

• Change the keyboard shortcuts at edge://extensions/shortcuts.
• Edge may show a "Turn off extensions in developer mode" prompt after a restart. Choose Keep (or dismiss it) to keep the extension. A store listing for Edge Add-ons is on the roadmap.
• Exports go to Edge's downloads list (Ctrl+J), like any other download.

Firefox 140+ is supported through a separate build with a Firefox-specific manifest. The background runs as an event page instead of a service worker, and the manifest adds a Gecko add-on ID. It isn't on addons.mozilla.org yet.

1. Build it: npm install && npm run package:firefox → dist/meet-attendance-tracker-v<version>-firefox.zip.
2. Open about:debugging#/runtime/this-firefox, click Load Temporary Add-on… and pick the zip (or dist/firefox/manifest.json).
3. Join a call on meet.google.com. If Firefox asks, allow the extension to run on that site (Extensions menu → Meet Attendance Tracker).

Temporary add-ons are removed when Firefox restarts. For a lasting install you need a signed build, which comes with the planned AMO listing. npm run lint:firefox runs Mozilla's web-ext lint on the build.

git clone https://github.com/SahinurDEV/Meet-Attendance-Tracker.git

Then load the extension/ folder with Load unpacked. There's no build step: extension/ is plain JavaScript, HTML and CSS.

1. Join a call on meet.google.com. Tracking starts automatically.
2. Click the floating Attendance button in Meet (or the toolbar icon) to see the live list, who's missing and join/leave alerts.
3. Press Save now (Alt+Shift+S) any time, or let auto-save do it.
4. Export from the panel, or open the Dashboard for history, rosters, analytics, series and bulk exports.

Tips

• Meet only renders some video tiles in big calls. Keep the People panel open for the most complete list.
• Open the chat panel at least once during the call if you want the chat saved.
• Create a roster under Dashboard → Rosters and link it to your recurring meeting code to see absentees live.

• Local only. Attendance, rosters, chat and settings live in chrome.storage.local in your browser. Uninstalling the extension removes them.
• No network. No servers, accounts, analytics or third-party scripts. A static check (npm run lint:manifest) fails the build if extension code uses fetch, XHR, WebSockets or remote scripts, and the integration tests assert that no request leaves the device.
• No audio or video. Only names, indicators and chat messages that Meet already shows on screen are read.
• Minimal permissions. storage, plus a content script on https://meet.google.com/*. Keyboard shortcuts (commands) and chrome.i18n need no permission, downloads use <a download>, and the clipboard is written from a user click.
• Your control. Delete single meetings or everything, or export/import a JSON backup.

Full policy: Privacy Policy. Please follow your organisation's policies and local laws when recording attendance.

Requires Node.js 20+.

Unit tests (test/unit, 54 tests) cover name normalisation, session merging, join/leave/rejoin and grace handling, speaking time, resume after reload, chat de-duplication, roster CSV parsing and matching, late / minimum-time rules, analytics (per person, overview, series matrix), SVG charts, storage (rosters, user fields surviving auto-saves) and every encoder. XLSX is read back with SheetJS; PDFs are checked structurally (xref offsets, stream lengths, image XObjects with soft masks, RunLength round trip) and with pdftotext/pdfimages when poppler is installed. An i18n test checks that every string used in the code exists in both locales with matching placeholders, and that the store-facing strings are plain sentences rather than keyword lists.

Integration tests (test/integration, 13 tests) launch Chromium with the unpacked extension and route https://meet.google.com/* to test/fixtures/mock-meet.html, a Meet-like page whose participants join, leave, flicker, speak and chat on command. They cover the manifest (no manifest/runtime errors), the live panel, manual and auto-save, roster import, absentees and late/short statuses in the panel, join/leave toasts, chat capture, both keyboard-shortcut commands, copy as table, JSON / chat CSV / XLSX / Bengali PDF exports, tags, notes, tag filter, bulk export, analytics, person history, series matrix exports, dark mode, the Bengali UI, and that no request leaves the device.

The popup and dashboard read live state from live:<tab> keys that the Meet tab refreshes every few seconds. Save now in the popup is sent to the tab through a cmd storage key, and shortcuts are forwarded with tabs.sendMessage, so the extension needs no tabs permission.

Non-Latin text in PDFs. The standard PDF fonts only cover Latin-1. Instead of bundling multi-megabyte fonts, any text outside WinAnsi is drawn by the browser (which shapes Bengali conjuncts correctly) onto a canvas and embedded as an anti-aliased image mask in the brand colour. Latin text stays real, selectable PDF text.

• Google Meet's markup is obfuscated and changes without notice. Detection uses several strategies, but a Meet redesign can still break it until the selectors in extension/lib/detect.js are updated. The chat selectors in particular are best-effort.
• Chat is only captured while Meet has rendered it (the chat panel was open at some point). Messages without an id that have the same sender, text and minute are merged.
• Speaking time depends on Meet showing a speaking indicator for that person. People without a visible tile may not have speaking time recorded; keeping the People panel open helps.
• Participants are identified by display name, so two people with exactly the same name are merged. Roster matching is name-based (Meet doesn't expose emails to the page).
• Times are sampled about once a second, and leaves are recorded after the grace window (default 10 s), dated to when the person was last seen.
• Non-Latin text in PDFs is drawn as images, so it isn't selectable or searchable in the PDF, and it needs a font for that script on the computer (Windows and macOS include Bengali; on Linux install e.g. fonts-noto-core). Without a browser canvas (e.g. in Node), it falls back to ?.
• Analytics treat a person as "expected" at every meeting of a series they attended at least once, plus every meeting whose roster lists them.
• The Bengali translation was written for this project; native-speaker review is welcome.
• Chrome may throttle background tabs. Speaking-time samples are capped so a throttled tab doesn't over-count, but accuracy is lower while the Meet tab is in the background.

Planned, not built. Anything involving a cloud service would be strictly opt-in; local-only stays the default. Want to help? Look for good first issue and help wanted.
