By the end of this guide you can ask ChatGPT or Claude about the lessons already in GapFiller: what you are teaching, what you did last time, and which lessons are still unprepared.
What the assistant can see
ChatGPT and Claude can read lessons you created. That includes the title, date, class, subject, whether the lesson is prepared, and the text you typed in the plan or summary.
They cannot:
- create, edit, or delete a lesson
- open your gradebook, student names, or files
- see a lesson a colleague created, even when you teach the same subject
When a lesson is retrieved, the text you typed is sent to ChatGPT or Claude. Names you wrote in a plan are included. More detail is in the privacy policy.
You need an active GapFiller plan, and an account that signs in with email and password. An account that only uses Google or Microsoft cannot connect. Being already signed in to GapFiller in the browser is not enough: you sign in again on the connection page. That page is in English.
Connect ChatGPT
- In ChatGPT, open Settings, then Apps and connectors.
- Search for GapFiller and choose Connect.
- Sign in with the email and password for the GapFiller account you want to connect.
- Read what will be shared, then click Allow.
Connect Claude
- In Claude, open Settings, then Connectors.
- Search for GapFiller and add it.
- Sign in with the same email and password, then click Allow.
The sign-in page is the same one ChatGPT uses.
Questions you can ask
- What am I teaching tomorrow?
- What did I do last time with 2B History, and what am I doing next?
- Find the lesson where I introduced the French Revolution.
- Which lessons this week are still unprepared?
- Summarize what I have covered with 1A this month.
If two classes share a name, say the subject as well. "2B" on its own may mean History or Maths.
The answer stays in the chat. GapFiller does not save a new plan from ChatGPT or Claude. Open the lesson in GapFiller when you want to edit it.
Disconnect
Remove GapFiller in ChatGPT or Claude. That stops new questions from that app.
To turn off access that was already allowed, open the disconnect page, sign in, and disconnect every assistant.
