Sider Common Mistakes to Avoid

Mistake #1: Using One AI Model for Everything

Mistake #2: Trusting Answers Without Checking

Mistake #3: Not Pinning the Extension

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.
