As a PhD student, I read dozens of papers weekly. Sider's summarization and question AI extension saved me hours. I can ask questions about complex concepts without leaving the PDF or article I'm reading.

Dr. Sarah Chen

I work with international clients across Europe and Asia. The translation in Sider works better than Google Translate for technical terms and formatting.

I used to copy-paste content into ChatGPT constantly. Now Sider is right there in my sidebar. The multi-model comparison helps—Claude gives better creative suggestions, GPT-5 is better for technical questions.
