01
Discover
Fireflies finishes transcription. ClassSync discovers the meeting through the relay or recovery polling and fetches the transcript directly.
Local-first university manager
From lecture to study notes, quietly.
ClassSync picks up completed Fireflies transcripts, identifies the right subject with Gemini, writes structured notes, and publishes them to your Notion study workspace — with almost no interaction.
One quiet pipeline
Your lecture finishes. ClassSync takes it from there.
The client keeps the useful data and credentials on your device. The relay exists only to wake devices up and coordinate work safely.
02
Understand
Gemini matches the lecture against your active subjects and turns raw speech into structured Portuguese study notes.
03
Publish
The note lands in your Notion summary database, linked to the right subject and protected against duplicate publishing.
Privacy by architecture
The relay never needs your lecture.
Transcripts, summaries and Notion content stay between your device and the services you chose. The Cloudflare relay stores identifiers, timestamps and encrypted account sync data — not lecture text.
What stays where
Credentials → OS secure storage
Queue → local SQLite
Transcripts → device
Summaries → Notion
Wake-up metadata → relay
More than lecture summaries
A study desk that keeps working offline.
Windows + Android
Background processing, notifications and a local durable queue keep work moving across the platforms ClassSync targets.
Academic context
Optional ISEP Portal and Moodle integrations bring timetable, grades, assignments and announcements into the same local-first experience.
Recovery built in
A recovery code can restore your encrypted ClassSync setup to another device without handing over your service passwords.
