Microsoft Edge’s Sidebar just got a big boost for AI users.
Copilot within the Sidebar can now show previous conversations and it supports Think Deeper.

The Edge Sidebar is a versatile tool that now supports a feature-rich version of Copilot.
The addition was spotted by Leo Varela, whoshared screenshots on Reddit.
The new features are rolling out gradually, so you may not have them at this time.
These additions make Copilot in the Sidebar more comparable to its web and Android versions in terms of features.

Copilot was added to the Edge Sidebar back when the AI tool was in preview and still used the Bing Chat branding.
In fact, Copilot in the Sidebar now beats its web counterpart because it can show previous conversations.
At least for me, Copilot on the web does not show a way to review previous conversations.
What is Think Deeper?

Think Deeper is a Copilot feature powered by OpenAI’s o1 model.
It is designed for complex tasks that require context and comparison.
In my testing, follow-up questions from Copilot are much better when using Think Deeper.

Copilot users can use Think Deeper for free, though Copilot Pro users get preferred access during peak usage.
I calledSidebar the “best net web client feature you’ve never heard of"back in 2022.
Sidebar creates a small tab that it’s possible for you to hide or expand on demand.

That tab can show anything from messaging apps like Telegram to tools like a calculator.
The feature has received several updates since its initial launch.
Until recently, Copilot within the Edge Sidebar had limitations that the web version of Copilot did not.

The addition of conversation history helps bring the Sidebar version of Copilot to parity with Copilot on the web.
The addition of Think Deeper is also a welcome upgrade.
