Sider
by Vidline Inc.
The verdict
Sider is strongest for people who want several AI models one click away while they browse, read and research. It is less ideal as a secure workspace for confidential material, and the sidebar can feel crowded. It is worth considering if you pay for more than one chatbot and want them in a single subscription.
Best for
- Comparing answers from several models side by side
- Summarizing articles, PDFs and YouTube videos while browsing
- Translating web pages in place
- Researchers and operators who switch between chatbots all day
Not best for
- Confidential or regulated data, since it runs as a browser extension
- People who want a simple, minimal interface
- Heavy daily use on the free tier, which has tight limits
- Users who need full feature parity on mobile and desktop apps
