What Is Sider AI?

The best way to describe Sider is it’s an all-in-one AI assistant. It’s a collection of all the major AI models out there, like GPT, Claude, Gemini, DeepSeek, etc., which we can switch between and use as needed.

With the latest update, Sider added a new major researching feature. It can now conduct an in-depth, human-like research on any topic and generate a well-crafted research doc you can use to identify trends, statistics, and more.

On top of that, you also get other extra features like:

• Translation.

• OCR.

• Grammar checker.

• YouTube summariser.

• AI image editor, etc.

It’s basically what we can call everything we need in one place.

Since we mentioned its grammar checking feature, you should check out our LanguageTool review if you’re looking for an affordable, minimal AI proofreading tool.

5 Key Features of Sider.AI

Sider has a lot of features we can play around with. But going through them all can be very overwhelming, especially if you’re new to Sider.

So here, I’ll take you through the five best features of Sider.AI that makes Sider good at what it does.

1. Browser Extension + Sidebar

This is what makes Sider so good. With the browser extension, it brings you an abundance of AI tools to your browser’s sidebar, making every possible AI support you need easily accessible.

You no longer have to open up or switch between tabs every time you need help from AI. That’s pretty handy for me as a writer, because it works just like nudging a colleague for help.

You won’t lose focus on your task, and you’ll get the help you need.

2. AI Models

Sider includes 10+ major AI models, including the basic and advanced versions of each AI.

So, for ChatGPT, you get:

• GPT-4o and 4-o mini, which are the free versions.

• GPT 4.5, o3-mini, and o1, which are the paid version.

And likewise for other AI models.

Each AI model and their versions serve different purposes. For instance, GPT-4o mini is great for getting everyday tasks done quickly, while Claude 3.7 Sonnet excels in coding.

So depending on the type of work you’re doing, you can easily toggle between these AI models and their versions as needed, without having to open up and switch between multiple browser tabs of different AI assistants.

3. Deep Research

Although it’s a new feature, I’m already in love with it. Especially since it immensely helps with my work, as the Deep Research feature easily automates the hefty part of my job.

You can get a well-crafted, high-quality, human-level research doc in just a few minutes by inputting what you need the research to be done on.

It’s the time and quality of output that fascinates me!

Along with the research doc, you’ll get the list of sources, as well as a list of AI notes of the key parts of the research.

Even better, you can even generate an interactive report of the research in a few minutes.

However, the interactive report can be only downloaded as an HTML file, so it’s pretty useless unless you know how to play around in a graphic designing tool and manually copy the report there.

Would’ve been so great if there was an option to save it as a PDF or image. Fingers crossed!

4. YouTube Video Assistance

I’m someone who can easily waste hours on YouTube. I watch it like you binge on a TV show.

BUT Sider has been a great help for me on that front.

One, it’s got a very handy summarising feature for YouTube videos. No matter how long the video is, you’ll get a quick summary along with a list of the key highlights of the videos written down for you.

With that, you can easily consume the essence of a 15-minute video in a minute or two.

Then, you have the AI video shortener option.

It basically creates a shorter version of the YouTube video by retaining only the key areas, which you can watch or download for later.

I personally prefer the summarising option since that’s way quicker. Sider does take a few seconds or minutes to shorten the video, and I’ve lost my patience to wait on a loading screen in this era of TikTok and reels.

5. Reads Browser Tabs

When you open Sider’s sidebar while browsing a website, Sider will automatically detect it and ask if you’d like to summarise the web page.

I have to say, this is a very neat feature compared to other AI assistants. With them, you’d have to manually input the URL, but that’s not the case here.

Sider AI: Pros & Cons

Pros

• Easy access: The fact that you can access sider easily with a click on the browser extension is a handy feature.

• AI options: Being able to use multiple AI models and version is one place is useful, especially when one AI model’s server is down.

• In-depth research: You can easily generate a well-crafted, highly detailed research doc in minutes.

• Quick & efficient: Outputs are generated at a very fast pace.

• Stability: Sider AI has been stable for the past 5 months of my usage, with zero bugs, crashes, or downtime so far.

• Compatibility: Sider extension is available on major browsers like Safari, Chrome, and Edge. Their app is also available for Mac, Windows, iOS, and Android.

Cons

• Too many features: Being an all-in-one AI assistant, Sider has many tools to offer, which may be overwhelming.

• Ease of use: With too many features scattered around, I’ve found it difficult sometimes to navigate around.

• Research report: The current way to save the interactive research report is useless. Would be heaps better if they add the option to download it into a PDF or image.

• GPT-4o mini.
