Classroom Diaries
Teach the lesson. Classroom Diaries writes it up.
A Mac app for language teachers. Record a lesson in the classroom or online, transcribe it on your Mac, and let Classroom Diaries pick out the vocabulary, corrections, pronunciation and grammar you actually taught. After you review it, one dated entry goes into that class’s Google Doc.
In daily use with 25 classes · Audio never leaves your Mac · Signed and notarized

What it does
What Classroom Diaries does
Writing up every lesson for every class takes hours a week. Classroom Diaries does the write-up, and you stay in charge of what gets published.
-
Record in person or online
Record the room with your Mac’s microphone. For online lessons it records both sides of the call, and you can also import audio you recorded on your phone.
-
Transcribed on your Mac
Apple’s on-device speech recognition turns the lesson into text. The audio never leaves your Mac.
-
Only what you taught
The extraction picks out the words, corrections, pronunciation and grammar you deliberately covered, and skips hard words that were only used in passing.
-
You review everything
Edit, reorder, add or move items between the four categories before anything is saved or published. Re-extract any time with an improved prompt.
-
Straight into the class Doc
Publish adds one formatted, dated entry to the class’s own Google Doc in date order. Re-Publish replaces that one entry and nothing else.
-
A history for every class
Each class keeps its own lesson history on your Mac, even after recordings and transcripts are deleted. Cancelled classes get an entry too.

How it works
From lesson to Google Doc in five steps
Pick a class, then work down the list. Each step waits for you.
-
1
Record
Record in the classroom or on a call, or import an audio file. Jot live notes or the coursebook unit while you teach.
-
2
Transcribe
On-device transcription turns the recording into text. Several lessons can transcribe at once.
-
3
Extract
Your transcript goes to Anthropic’s Claude with your own API key, which picks out what you taught and writes the lesson’s subject line.
-
4
Review
Check and edit the vocabulary, corrections, pronunciation and grammar, and the subject line.
-
5
Publish
Save it to the class history, copy it, or publish it to the class’s Google Doc at its date.
Your data
Your lessons stay yours
Classroom Diaries has no servers, no accounts and no analytics. Recordings, transcripts and lesson history are stored on your Mac, and you decide how long each is kept, with stricter settings for classes with younger students.
When you connect your Google account, the app writes only the lesson entries you publish, into the Docs you choose. Before it writes, it reads the headings in that Doc so the entry lands at the right date. No Google data is ever sent to an AI service.
Read the Privacy Policy and the Terms of Service.
- Audio is transcribed on your Mac and never uploaded
- Only the transcript text goes to Anthropic, with your own key
- Google tokens are kept in your Mac’s Keychain
- Recordings delete themselves after 30 days by default
