Mistake #2: Trusting Answers Without Checking
❌ Faux : Copying facts and numbers straight into your work.
✅ À droite : Open the cited sources and verify anything you plan to publish.
Mistake #3: Not Pinning the Extension
❌ Faux : Digging through the extensions menu every time you need Sider.
✅ À droite : Pin Sider and use the keyboard shortcut to open it immédiatement.
Sider Troubleshooting
Problem: The Sidebar Won’t Open
Cause: Browsers block extensions on some pages, like settings and the Web Store.
Réparer: Open a normal website and click the Sider icon again. Check the extension is turned on.
Problem: You Hit Your Usage Limit
Cause: The free plan includes a limited number of daily credits.
Réparer: Wait for the daily reset, or move to a paid plan for higher limits.
Problem: A PDF Won’t Upload or Read Correctly
Cause: The file is too large, or it’s a scanned image with no text layer.
Réparer: Compress or split the file. Run OCR on scanned pages before uploading.
📌 Note: If none of these fix your issue, contact Sider support.
