Presynce Attendance Tracker

Automatically track Google Meet attendance with standardized participant names and attendance matrices across multiple sessions.

Presynce automates Google Meet attendance tracking — no manual roll calls, no messy name lists. Presynce is a Chrome extension paired with a web dashboard that captures who attended your Google Meet sessions, how long they stayed, and when they joined — automatically, in the background, while your meeting runs. Key features: 📋 Live attendance capture — Tracks every participant in a Google Meet session, including join time and total duration present, even if they leave and rejoin. 🔤 Automatic name standardization — Converts inconsistent display names into a clean, sortable "Last Name, First Name M." format, arranged alphabetically — no more manual cleanup in a spreadsheet. 📁 Groups & longitudinal matrix — Organize sessions into groups (classes, teams, cohorts) and view a consolidated attendance matrix across every session in that group, at a glance. ⚙️ Configurable attendance rules — Set Late and Absent thresholds based on join time or session-duration coverage, and choose how Late attendees count toward totals. 🔍 Instant absentee detection — Compare a session's attendees against a group's roster and get an absentee list in one click. 🛡️ Host/observer isolation — Flag hosts, TAs, or observers so they're excluded from attendee counts and exports. 📤 Export anywhere — Download individual session records or full group matrices as Excel or PDF. 🔒 Local-first & private — Your records stay in your own browser by default. Sign in with Google only if you want optional cloud backup and cross-device sync — nothing is ever sold or used for advertising. Built for educators, teaching assistants, HR professionals, and anyone who runs recurring Google Meet sessions and needs reliable, organized attendance records without the busywork.
