Meet Sider 5.0: AI-Powered Deep Research for Everyone

Two years ago, we launched Sider to make AI accessible to everyone. As large language models emerged, we saw an opportunity. Sider helps users understand instantly and broadly. The sidebar extension delivers instant translations, summaries, explanations, and writing help right where you browse. Access to ChatGPT, Claude, Gemini, and DeepSeek ensures broad understanding from different angles.

Since then, over 10 million of you have joined us. We're humbled and proud to be part of your days.

The world has shifted. AI used to mean access; today, it's about focus. Information is everywhere, overwhelming us. Fast answers aren't enough—users need to understand deeply to navigate the chaos. That's why we created Sider 5.0 for deep research.

Introducing Deep Research & Wisebase

Life's full of questions—big ones, small ones, messy ones. Sider 5.0 is here to help you conquer the info overload with ease and confidence. We give you depth you can trust, speed you can feel, and a space to make it your own.

Deep Research Agent

Imagine an AI research partner that mimics human research and works hands-free:

Ask a question, and it figures out exactly what you mean

It digs through 100+ web sources, picking only the good stuff

It highlights key information and even creates insightful notes that expand on the topic

It reflects during the process

It generates a well-structured report with proper citations and sources

It creates a visualized, interactive version of your report

All of this happens automatically, transforming what used to be hours of manual research into minutes of waiting while AI does the heavy lifting.
