Sider AI vs Jetwriter AI: Which AI tool is best for writing? Jetwriter helps you write emails and messages faster. See why it's better for writers.

Are you confused by all the new AI tools? It feels like a new one pops up every week.

This leads to a big question. Should you get an AI tool that does a little bit of everything? Or should you get a tool that is great at just one thing?

Let's look at two tools, Sider AI and Jetwriter AI, to see the difference.

First, let's talk about Sider AI. Sider AI is an AI assistant that does many different jobs. You can ask it to do all kinds of things. For example, it can do deep research on the internet, chat with websites or PDFs, and help with many general tasks.

Sider AI is a tool you can use for many broad, all-in-one tasks.

Now, let's look at Jetwriter AI. Jetwriter AI is different. It has only one main job: to help you write better. Jetwriter AI helps you with all your writing tasks. You can use it to write emails and messages very fast, fix all your spelling and grammar mistakes, change your writing tone (like sounding more professional or more friendly), and make your sentences shorter and clearer.

So, which one should you pick?

Sider AI is a fine tool if you need an assistant for many different things, especially research.

But what if your job is mostly writing? Maybe you work in sales, customer support, or marketing. You are in your email inbox all day. You write to customers and your team. Writing is your job.

This article is for you. We will show you why a special writing tool like Jetwriter AI is the better choice to help you with your daily writing.

What Are Sider AI and Jetwriter AI?

Before we get into the details, let's look at what these two tools actually are.

Sider AI

Sider AI is like a helpful assistant that lives in your web browser. Its main job is to be your "copilot" for all your internet tasks. You can use it for:

Deep research: It can look up topics for you and find information.
Chatting with pages: You can "talk" to a website or a PDF file and ask it questions.
Summarizing: It can read long articles or web pages and give you a short summary.
General tasks: It helps you with a wide varietyof other jobs on the web.

Sider is a broad tool for many general needs.

Jetwriter AI

Its main job is to help you with any writing task you have. It is built to make your writing perfect.

You can use it for:

Composing emails and messages
Correcting grammar and spelling
Rephrasing your sentences to sound better
Changing your writing tone (like more professional or casual)
Helping you write better and faster, every single day

Jetwriter is a special tool made just for writers.

Workflow & Integration

Your AI tool should work right where you do your job. No one likes to switch tabs! In this section, we will compare Sider AI and Jetwriter AI inside Gmail. We will also show you the special help Jetwriter AI gives you in other applications, like LinkedIn, Freshdesk, Microsoft Outlook, and Zoho Mail. Let's find out which tool really makes your work faster.

Write Gmail Replies Faster

We all spend a lot of time in Gmail, right?

Both Sider AI and Jetwriter AI will add a small button right inside your Gmail. This is a very helpful feature. Having the button right there means you don't have to leave your email to use the AI.

When you open an email, you will see that both tools are quite smart. They can read the whole email chain. This important ability to understand the full conversation is called "context.”

All you have to do is click that button. You don't need to write the full, polite email by yourself. You just type a very short note, like a simple instruction.

For example, you can just type a few words, like:

"say I am interested and want to apply"
"ask them if we can meet tomorrow"

It's that simple. Both tools will then take your short note and use it with the "context". The AI does all the hard work. It will write a complete, full email reply for you. This is a very nice time-saver.

But here is where they are very different.

The Jetwriter Difference: You Are in Control

Jetwriter AI gives you total control over that reply. Sider's help is more basic.

Control After You Write

What if the email draft isn't perfect? It happens. Maybe the tone is too serious or casual, or it's just too long.

With Jetwriter AI, this is easy to fix. You have many options and don't have to start over.

You can rewrite the draft in one click. If the email sounds too formal, click a button to change the tone to "Friendly." If it's too long, click the "Shorter" option to make it concise.

Jetwriter lets you keep fixing the email until it is just right. Sider's tool is simpler and does not give you these specific controls.

Smart Replies on LinkedIn

If you spend a lot of time on LinkedIn talking to clients or connections, this is a real game-changer. You will love this. Sider AI does not have this deep integration. Jetwriter AI does.

And Jetwriter is very smart. It understands your whole chat history with a person. It instantly reads and knows what your conversation is about. This means you can draft very helpful replies that are perfect for the conversation. These are called context-aware replies. And you can get them in just a few seconds.

Faster Replies for Customer Support

If you work in customer support and use Freshdesk, you will love this. It's a real game-changer. Sider AI does not have this integration, but Jetwriter AI does.

Jetwriter AI is very smart. When you open a customer's ticket, it reads it right away. It fully understands what the customer's problem is. Because it understands, it helps you write a perfect reply. It saves you a lot of time and helps you answer customers in just a few seconds.

Easy Replies in Outlook

What about Microsoft Outlook? Jetwriter AI helps you right there, but Sider AI does not.

It's very smart. When you open an email, Jetwriter reads the whole thread for you. You click "AI Reply" and type a short note (like "Say yes" or "Politely say no"). The AI writes the full, professional email. And you are in charge. You can change the tone or length, "Regenerate" a new draft, or "Edit" the text yourself. Once you like it, click "Insert."

Zoho Mail Replies Made Simple

What if you use Zoho Mail? Jetwriter AI helps you there, too. This is another special feature that Sider AI doesn't offer.

It's very smart. When you're in a Zoho email, Jetwriter reads all the past messages. It understands the context. You just tell it what to do. Type a short note like "Follow up" or "Thank them for the link." Jetwriter does the hard work and writes the complete email.

And you always have the final say. You can easily change the draft. Want a "Formal" tone? Need it "Shorter"? Just click. You can also "Regenerate" a new version or "Edit" it. When you are happy, click "Insert" to add it to your reply.

Quick Actions: Customizing Your 1-Click Workflow

When you select some text on a website, a toolbar with menus pops up. This is the "Quick Actions" menu. It helps you do common tasks in just one click.

Both Sider AI and Jetwriter AI have this feature. When you highlight text, they both show you a menu with helpful buttons.

You can do all the basic tasks, like:

Fix Spelling & Grammar
Improve Writing
Summarize the text
Translate it

This feature lets you stay focused on your work. It's a very fast way to make edits without all the extra steps. This is how a real AI writer should work. It is available right where you need it.

The Jetwriter AI Difference: Create Your Own Actions

Jetwriter AI lets you create your own 1-click actions. Sider does not.

This is a very big deal. It means you can make the tool work exactly how you want it to. You can add your own special buttons to the menu for the tasks you do every day.

For example:

If you are a marketer: You can create an action called "Make this a LinkedIn post."
If you are a manager: You can create an action called "Convert to Bullet Points."
If you are a student: You could even make one called "Explain this like I'm 5."

Sider gives you a basic menu. Jetwriter AI lets you build your own perfect menu. You are in control.

Personalization: Does the AI Sound Like You?

Have you ever used an AI tool and thought, "This just doesn't sound like me"? The writing is often plain and has no personality. A good AI assistant should learn about you.

Both Sider AI and Jetwriter AI have a "Personalize AI" feature. This is a place where you can tell the AI about yourself. For example:

What is your job? ("I am a customer success manager.")
What do you do? ("I love solving customer problems.")
How do you like to write? ("I like to be very clear, friendly, and helpful.")

This helps the AI understand you, so it can give you better, more relevant answers.

How Jetwriter AI Takes Personalization to a Higher Level

Sider has this basic feature, but Jetwriter AI gives you two extra, very powerful tools.

Custom Writing Styles

Sider lets you pick a simple tone (like "Formal" or "Casual").

Jetwriter AI lets you create and save your own detailed writing styles. You can create a whole "persona" for all the different ways you need to write.

For example, you can create and save:

A "Concise & Direct" style: For when you write to your busy boss.
A "Friendly Team Update" style: For when you talk to your teammates.
A "Helpful Support" style: For when you answer customer questions.

You just create these styles once. Then, you can use them anytime with one click.

Prompt Templates

Do you find yourself typing the same commands to your AI every day? Jetwriter AI lets you save your most-used or most complex prompts.

For example, you can save prompts like:

"Summarize this email and list all action items for me."
"Write a polite follow-up email and ask if they have an update."

Now, you can do these big tasks with just one click. This saves so much time.

The Verdict: Here is the big difference. Sider can help you adjust your text's tone for one-time use.

Jetwriter AI learns to write in your unique voice. And it automates your specific, repetitive tasks. It truly becomes your personal assistant.

User Experience & Ease of Use

How an AI tool feels is very important. Does it get in your way? Or does it make your job easier?

Let's look at how Sider AI and Jetwriter AI feel when you use them.

When you open Sider AI, it launches as a sidebar (mostly towards the right). This is a panel that sticks to the side of your web page. The sidebar pushes the webpage you are working on to the side. This causes a "layout shift."

Your whole screen resizes, and your working area gets smaller.

You also cannot move the Sider sidebar. It is stuck on the side of your screen. You also cannot change the size of the sidebar to make it smaller. It gets in your way.

The Jetwriter AI Experience (A Flexible Window)

Jetwriter AI is very different.

When you open Jetwriter AI, it launches as a small, separate window. This window "floats" over your screen. This is a much better experience.

You can move it anywhere you want.
You can resize it to make it bigger or smaller.

Your workflow is never interrupted. You can drag the Jetwriter window right next to the email you are writing. It does not resize your screen or push your work around.

It is there when you need it, and out of the way when you don't.

Language Support

Does your AI assistant speak your language? If you work with people around the world, this is a very important question.

Sider AI is a powerful tool for this. It supports 54 different languages. This is a very good number and helps many people.

But what if your language is not one of those 54?

Jetwriter AI is different. Jetwriter AI offers support for all languages.

This means you are not limited.

For Business: Imagine you have a new client in Germany. You need to write a polite email in German. With Jetwriter AI, you can get help with your writing in German, or any other language.
For Personal Use: Maybe you want to write an email to your family in your native language, like English, Arabic, or Chinese. Jetwriter AI can help you fix grammar and sound clear in all of them.
For Learning: Are you learning a new language, like Korean or Portuguese? You can practice writing in that language, and Jetwriter AI can help you improve your sentences.

It does not matter what language you speak or write in. Jetwriter AI is built to help everyone, everywhere.

Performance, Price, and Privacy

These are very important for any tool you use for your job.

Performance

Do you hate when your browser gets slow and laggy? Heavy extensions are often the problem.

Sider AI is a big all-in-one tool, so it's a heavier extension. Its size is over 25MB.

Jetwriter AI is built to be a specialist. It is super light. The extension is tiny (less than 1MB!).

This means it won't slow down your computer or make your typing lag. It's fast and stays out of your way.

Pricing

Now, let's talk about money.

Jetwriter AI is positioned as a more cost-effective solution for you.

With Sider, you are paying for a tool with many features, like research and chatting with PDFs. But what if you only need help with writing? With Jetwriter, you are paying for a special writing tool. You get all the advanced writing features you need, for a better price.

For both Sider AI and Jetwriter AI, you can also use your own API key from other AI providers (like OpenAI) to generate responses.

Privacy

This is the most important part. You need to know your work emails and private messages are safe.

Sider's Policy: Sider's privacy policy says they collect "Usage Information" and "Analytics and Performance Data." It also says they can use your data for "Analytics and Research." This helps them improve their product, but for a user it means they are looking at your data.
Jetwriter's Policy: Jetwriter's policy is very clear and very different. There is an explicit "no-training" promise. Your data is never used to train AI models. Your private information is not sold to anyone.

With Jetwriter AI, you know for a fact that your writing, your emails, and your company's information stay private.

Conclusion

So, which tool is right for you?

Let's be clear. Sider AI is an excellent and powerful tool. If your main job is doing research, chatting with websites, or summarizing PDFs, it is a great choice. It's a good all-in-one assistant for general browsing.

But what if your job is writing? What if you are a professional, a marketer, or a customer support agent? What if you are in your email inbox all day?

For you, Jetwriter AI is the clear winner.

Why? Because it is a specialist.

It is faster (the extension is tiny and won't slow you down).
It is more secure (it has a clear "no-training" privacy promise).
It is more flexible (the movable window stays out of your way).
It is more personal (you can create your own styles and actions).

Jetwriter's features are built just for writing. It truly learns your voice. It works inside your email and LinkedIn. It is made to help your writing workflow, not just be another tool on the side.

The choice is simple.

If you need an AI to help you with research and browsing, Sider is a good tool.

But if you need an AI to help you write, you should try Jetwriter AI.
