Troubleshooting

Upload Issues

"File too large"

• Maximum file size is 100 MB. Split your PDF into smaller batches using a PDF splitter tool.

"Too many pages"

• Maximum is 200 pages per upload. Split into multiple uploads.

"Unsupported format"

• Only PDF files are currently supported. Convert other formats (TIFF, DWG, etc.) to PDF first.

Processing Issues

Processing is taking a long time

• Typical processing time is 1-3 minutes per page. Large uploads (50+ pages) may take 10-30 minutes.
• Complex, densely annotated P&IDs take longer than simple ones.

"Processing failed"

• Your credits are not deducted when processing fails.
• Try re-uploading the file. If it fails again, the PDF may be corrupted or password-protected.
• Contact support if the issue persists.

Low accuracy / many missing instruments

• Check your PDF quality — scanned images below 150 DPI produce poor results.
• Vector PDFs (exported from CAD) work significantly better than scanned images.
• Non-standard instrument symbols may not be recognized.
• Dense annotations or markups overlapping instrument bubbles reduce accuracy.

Export Issues

Excel file won't open

• Ensure you have Excel 2010 or later, or use Google Sheets / LibreOffice Calc.
• Try downloading again — the file may have been corrupted during download.

Missing instruments in export

• The export includes all instruments shown in the review interface.
• Check if instruments were accidentally deleted during review.

Account Issues

Didn't receive verification email

• Check your spam/junk folder.
• Click "Resend verification" on the app page.
• Ensure you signed up with the correct email address.

Can't log in

• After 10 failed attempts, your account is locked for 15 minutes.
• Use the correct email (case doesn't matter) and password (case matters).
