Before you start
- Know your file: type (PDF, DOCX, TXT, audio, video), size and, for PDFs, page count.
- A steady connection. Big files need a stable connection to upload.
Steps
- Check the file type. Only PDF, Word (.docx), text (.txt), audio and video files work. Save slides or .doc files as PDF first. See supported files and limits.
- Keep the tab open during the upload. Wait until “Uploading source into Galileo…” finishes. After that, processing carries on even if you leave.
- Give it time. Documents usually take a minute or two; recordings a few minutes. We email you when it’s ready.
- Reload the session. If the progress card hasn’t moved for 15 minutes, reload the page or open the session from History.
- Upload again from the dashboard if the card shows failed.
- Make the file smaller if it fails again: split a long PDF, upload one chapter, or upload just the audio of a video.
Common errors and fixes
| Message | What it means | What to do |
|---|---|---|
| ”Unsupported file type” | The file isn’t PDF, TXT, DOCX, audio or video. | Convert it to PDF. |
| ”Upload failed” or “Failed to upload file into Galileo” | The upload was interrupted. | Check your connection and try again. |
| ”PDFs larger than 2000 pages are not supported yet” | The PDF is too long. | Split it into parts. |
| ”No content extracted from source” | No readable text or speech, often a scanned PDF. | Use a PDF with selectable text, or run OCR first. |
| ”Transcription timed out…” | The recording took too long to transcribe. | Split it into shorter parts. |
| ”source extraction timed out” or a failed card on a document | The document took too long to read. | Upload a shorter section. |
| ”Your trial or subscription has ended. Choose a plan to continue.” | You need an active plan to add sources. | Start the trial or subscribe. |
| ”Upload from dashboard” | Each session holds one source. | Upload new files from the dashboard. |
Tips
- Name files clearly before uploading so you can find them in History.
- Use Chrome or Edge for the most reliable uploads.
If something goes wrong
- The trial screen appears when I upload. You’ve used your free preview. See what you can do before your trial.
- It still fails. Contact support with the file type, size and the exact message you saw.
