Before you start
- A session with a source. Sessions started with a typed question only have the Galileo tab.
- Plan needed: the free preview shows your preview source; long transcripts are partly locked until you start the trial.
The tabs
| Tab | What it shows |
|---|---|
| Galileo | Your chat with the tutor. |
| The original PDF, page by page. | |
| Transcript | Audio transcript with timestamps, speakers and chapters. |
| Video / YouTube | The video with its transcript and Chapters. |
| Source | Text from a Word or text file. |
| Summary | The automatic summary of your source. |
Live lecture recordings open on Summary first; reopen the lecture with Transcript in the Galileo panel.
Steps
- Open a session from History or straight after an upload.
- Choose a tab at the top to switch between the chat, the source and the summary.
- Jump through a recording. Choose a chapter, or a line in the transcript, to move the player to that moment.
- Follow a citation. When Galileo cites your source in the chat, click the citation to open that place in the source.
- Open the source beside the chat. In the Galileo panel choose View PDF or Transcript.
- Rename a speaker. Choose the speaker label, then Edit Speaker Name, type a Display name and choose Save.
Tips
- Chapter titles improve after processing. You may see “Refining AI titles…” for a moment.
- Ask about a timestamp: “Summarise 20:00 to 30:00”.
If something goes wrong
- “No source yet. Upload a source and Galileo will open it here.” This session doesn’t have a source. Upload from the dashboard to start a session with one.
- “Preview unavailable”. A side panel couldn’t load; your chat is still fine. Reload the page.
- “No transcript is available for this lecture yet.” The recording is still processing or nothing was captured. See audio and transcription problems.
