10 Boring Websites Making Money Online — And How They Work

When people think about how to make money online, they often imagine building the next TikTok, Instagram, or huge technology startup.

But there is another side of the internet that gets much less attention.

Some of the most interesting online businesses are incredibly simple.

A website that tells you the time. A calculator that solves one specific problem. A tool that flips a virtual coin. A website that tests your reaction speed. A simple generator that randomly assigns Secret Santa gifts.

None of these ideas sound revolutionary.

And that's exactly the point.

You don't always need to build the next big social network to create a website that attracts thousands or even millions of visitors. Sometimes, a simple website that solves a specific problem can be enough to build a valuable online business.

In this article, I'm going to show you 10 simple and "boring" websites and explain what they do, how they attract visitors, and how websites like these can potentially make money.

More importantly, I'll explain what you can learn from these examples if you're interested in making money with AI, building websites, and creating online businesses.

Because with today's AI tools, building a simple website is easier than ever.

The difficult part isn't necessarily writing the code.

The difficult part is finding a problem that people are already searching for and building something useful enough that they want to come back.

1. Time.is — A Simple Website With a Huge Audience

Time.is is one of my favorite examples of a simple website that solves an extremely basic problem:

What time is it?

That's it.

Of course, Time.is does more than simply display the current time. Users can check the exact time in different locations, compare time zones, check sunrise and sunset information, explore calendars, and find information about locations around the world.

The website says it provides exact time information for more than 7 million locations and is available in dozens of languages.

Why is this interesting?

Because the underlying idea is extremely simple.

Someone searching for:

• current time in New York
• current time in London
• time in Tokyo
• time difference between countries
• exact time in a specific location

can potentially become a visitor.

And once you have a website attracting large amounts of search traffic, you have opportunities to monetize that attention.

Time.is even has a dedicated advertising page where it offers advertising opportunities to businesses.

What can you learn from Time.is?

You don't necessarily need a complicated SaaS product to make money with a website.

A useful tool + search traffic + a good user experience + monetization can become a real online business.

And this model can be applied to hundreds of other simple tools.

2. Omni Calculator — Turn Small Problems Into Thousands of Tools

Omni Calculator takes the calculator idea much further.

Instead of building one calculator, the website has built a huge library of calculators covering areas such as finance, health, mathematics, construction, sports, food, statistics, and more.

At the time of writing, Omni Calculator lists more than 3,900 calculators across multiple categories.

This is where the idea becomes particularly interesting for anyone learning how to make money with AI.

You don't necessarily need to come up with one massive website idea.

You can start with one useful calculator.

Then another.

Then another.

For example, you could create:

• mortgage calculators
• salary calculators
• calorie calculators
• percentage calculators
• age calculators
• profit margin calculators
• construction calculators
• finance calculators
• conversion calculators
• business calculators

Each individual tool can target its own search intent.

Over time, hundreds of useful tools can create hundreds of opportunities to appear in Google search results.

Omni's own story is particularly interesting. The company says it started from a small calculator project and eventually expanded into a large library of calculators, reporting millions of visits per month.

The lesson

Don't underestimate small problems.

A problem that seems too small to build a business around might actually be something thousands or millions of people need help with.

3. Starbucks Calorie Calculator — Go Extremely Niche

Here's another interesting approach:

Instead of creating a calculator for everyone, create one for a very specific audience.

Starbucks Calorie Calculator is an example of a website built around a specific brand and a specific problem: helping users understand the nutritional information associated with Starbucks drinks.

This is a much narrower concept than building a general nutrition website.

And that's exactly what makes the idea interesting.

You could potentially apply the same concept to many other niches.

For example:

• restaurant nutrition calculators
• fast-food calorie calculators
• coffee nutrition tools
• recipe calculators
• serving-size calculators
• nutrition comparison tools

The important idea isn't necessarily the Starbucks example itself.

It's the niche-down strategy.

Instead of trying to rank for a huge keyword like "calorie calculator," you can look for a much more specific search intent.

The monetization model

A website like this can potentially monetize traffic through display advertising and other relevant monetization methods.

The bigger lesson is:

You don't always need a huge audience. You need the right audience searching for the right problem.

4. Unit Converters — A Simple Idea With Hundreds of Variations

Unit converters are another example of a seemingly boring website idea with a huge number of possible variations.

Think about all the things people need to convert:

• miles to kilometers
• kilograms to pounds
• Celsius to Fahrenheit
• inches to centimeters
• liters to gallons
• feet to meters
• pressure units
• energy units
• currency
• time
• speed
• temperature

You could create one website covering many different conversions.

Or you could build a highly focused website around one specific category.

For example:

PressureConverter.com

could focus entirely on:

• bar to PSI
• PSI to bar
• Pascal to bar
• kPa to PSI
• atmospheric pressure conversions

Another website could focus entirely on temperature.

Another could focus on cooking measurements.

Another could focus on engineering conversions.

Why this works

People constantly search for quick answers to conversion problems.

They don't want to read a 2,000-word article explaining how kilograms work.

They want to enter a number and get an answer.

That's an important lesson when thinking about how to use AI to make money.

AI can help you build the tool, but the real value comes from solving a problem that people already have.

5. Wheel of Names and Random Decision Tools

Another interesting category is the random decision tool.

The basic idea is incredibly simple:

Enter several names or options, spin a wheel, and let the website randomly choose one.

This can be useful for classrooms, games, teams, events, content creators, and everyday decisions.

And the interesting part is that there are many variations of the same basic concept.

For example:

• wheel of names
• random name picker
• random choice generator
• wheel spinner
• random decision maker
• yes or no generator
• random number generator
• coin flip
• heads or tails
• random team generator

You don't necessarily need to invent an entirely new category.

You can take a proven interaction and adapt it to a specific audience.

For example:

Random Classroom Picker

could be designed specifically for teachers.

Or:

Random Team Generator

could target sports teams and gaming groups.

Or:

Restaurant Picker

could help people decide what to eat.

The technology behind these tools can be relatively simple.

The challenge is finding a useful niche and getting people to discover the website.

6. Secret Santa Generator — Solve a Seasonal Problem

DrawNames Secret Santa Generator is another great example of a simple concept solving a very specific problem.

Secret Santa is a gift exchange where each participant is randomly assigned another person to buy a gift for.

The traditional process can become annoying when you have to write everyone's names on pieces of paper, randomly assign them, and make sure nobody gets themselves.

A website can automate the entire process.

Users enter the participants, configure the exchange, and let the website handle the assignments.

Why is this a good website idea?

Because it solves a real problem.

And it has another interesting characteristic:

Seasonality.

People may not need a Secret Santa generator every day.

But around Christmas, demand can increase significantly.

This creates an interesting SEO opportunity.

You could build websites around other seasonal problems:

• Christmas gift generators
• Valentine's Day tools
• Halloween generators
• wedding planning calculators
• birthday party generators
• holiday planners
• New Year's tools

The lesson here is that a website doesn't have to be useful every day to be valuable.

Sometimes, being extremely useful for a few weeks or months each year is enough.

7. Just Flip a Coin — One Button, One Function

Just Flip a Coin is almost comically simple.

You visit the website.

You press a button.

The website gives you:

Heads or tails.

That's basically the entire concept.

And yet this type of website demonstrates something important about online businesses:

Simple doesn't mean useless.

People search for extremely basic things online because it's faster than finding a physical coin.

And once you understand this concept, you can start thinking about other simple tools.

For example:

• yes or no generator
• random answer generator
• decision maker
• random number generator
• random choice generator
• dice roller
• random team picker

The key isn't copying one particular website.

The key is identifying small decisions people repeatedly want help making.

If you can turn that decision into a useful, fast, mobile-friendly tool, you have the foundation of a website.

8. Reaction Tests — Turn a Simple Game Into a Searchable Tool

TestReaction is another interesting example.

The basic concept is to measure how quickly someone can react to a visual stimulus.

This type of website sits somewhere between a utility and a game.

And that opens up many possibilities.

You could build different types of tests:

• reaction speed test
• typing speed test
• reflex test
• memory test
• clicking speed test
• concentration test
• visual reaction test
• coordination test

The important idea is that the category is much broader than one website.

You can take a simple concept and create multiple variations around different keywords and use cases.

This is also where AI-assisted development becomes interesting.

A modern AI coding tool can help you generate the initial HTML, CSS, JavaScript, React, or Next.js implementation much faster than building everything from scratch.

But again, AI is the tool — not the business model.

The business model comes from creating something people actually want to use.

9. Typing Games — Combine Tools, Games, and Search Traffic

TypingGames.zone takes the idea one step further by combining typing practice with gaming.

Instead of simply giving users a typing test, the website can make the activity more interactive.

This creates an interesting opportunity because you can combine several concepts:

Useful tool + entertainment + repeat usage.

For example, you could build:

• typing games
• typing speed tests
• keyboard games
• vocabulary games
• memory games
• educational games
• reaction games
• spelling games

The advantage of this type of website is that users may spend more time interacting with the site rather than simply getting an answer and leaving.

That can potentially create more opportunities for advertising and returning visitors.

And again, the underlying technology doesn't necessarily need to be extremely complicated.

A simple JavaScript game can be enough to create the first version.

10. Temporary Email — A Useful Tool With a Clear Problem

The final example is the temporary email category.

Temporary email websites allow users to generate an email address that can be used for a limited period of time.

The concept became popular because people sometimes want to avoid giving their primary email address to every website they visit.

This category is more competitive than some of the ideas above, so I wouldn't recommend simply creating another generic temporary email website and expecting it to rank.

But that's actually the lesson.

When you find a competitive idea, ask:

Can I solve a smaller or different version of the problem?

Instead of building another generic temporary email service, you could look for a specific use case, audience, or workflow that isn't being served well.

The same thinking applies to almost every successful website idea.

You don't always have to invent something completely new.

Sometimes you can take an existing concept and make it:

• simpler
• faster
• more specialized
• easier to use
• better designed
• focused on a specific audience
• optimized for a specific search intent

That's where opportunities often appear.

What These "Boring" Websites Teach Us About Making Money Online

After looking at these examples, you might notice something.

Most of these websites aren't revolutionary.

They don't require a revolutionary social network.

They don't necessarily require thousands of employees.

They don't even need an incredibly complicated product.

Instead, they follow a relatively simple formula:

Problem → Useful Tool → Search Traffic → Monetization

And this is one of the reasons I find this business model so interesting.

You can start with a very small idea.

Build the first version.

Get it in front of users.

Learn what people are searching for.

Create additional tools.

Improve the website.

And eventually build an entire collection of useful tools.

How to Use AI to Build These Websites

This is where things get particularly interesting in 2026.

A few years ago, building 50 calculators, generators, converters, games, or interactive tools would require a significant amount of development time.

Today, AI coding tools can dramatically reduce the amount of time required to create the first version.

You can use AI to help with:

• generating JavaScript functionality
• building React components
• creating Next.js pages
• designing responsive interfaces
• writing SEO content
• generating calculator logic
• debugging code
• creating landing pages
• generating test cases
• improving accessibility
• creating documentation

For example, imagine you discover that people are searching for a specific type of calculator.

You could use AI to help you:

1. Research the problem.
2. Define the calculator's inputs and outputs.
3. Write the calculation logic.
4. Build the interface.
5. Make it mobile-friendly.
6. Create an SEO-optimized page.
7. Add supporting articles.
8. Deploy the website.
9. Monitor search traffic.
10. Build additional tools based on what people search for.

This is a very different approach to building websites.

Instead of spending six months building one huge application, you can experiment with many small ideas.

The Real Opportunity: Build Websites Around Search Intent

This is probably the biggest lesson from all 10 examples.

If you're trying to figure out how to make money online, don't start by asking:

"What website can I build?"

Start by asking:

"What problem are people already searching for?"

That's a much better question.

Someone searching for:

"meters to feet"

already has a problem.

Someone searching for:

"reaction speed test"

already wants a tool.

Someone searching for:

"Secret Santa generator"

already has a specific need.

Someone searching for:

"current time in Tokyo"

already knows what they want.

Your job is to build something that gives them the answer quickly and makes the experience better than the alternatives.

How These Websites Can Make Money

Once a website starts attracting meaningful traffic, there are several potential monetization models.

1. Display advertising

This is one of the simplest models.

You provide a free tool, attract visitors through search engines, and display advertisements on the website.

The more relevant traffic you attract, the more valuable the advertising inventory can potentially become.

2. Premium features

You can offer the basic tool for free and charge for additional features.

For example:

• remove ads
• advanced calculations
• saved results
• exports
• additional customization
• team features
• higher usage limits

3. Affiliate marketing

Some tools naturally connect to products or services.

For example, a financial calculator could potentially recommend relevant financial products, while a fitness tool could potentially recommend relevant equipment.

4. Selling your own products

The website can also become a traffic source for another business.

For example:

Free calculator → SEO traffic → email list → digital product

The tool doesn't necessarily need to be the final product.

It can be the entry point.

You Don't Need a Boring Website. You Need a Useful One.

Calling these websites "boring" is really just a way of describing how simple they look.

The best ones aren't boring to the person who needs them.

If someone needs to convert kilograms into pounds, the perfect website is probably not the one with the most impressive animation.

It's the one that gives them the answer immediately.

That's the opportunity.

If you're learning how to make money with AI, don't think only about generating AI images, writing AI content, or building the next AI chatbot.

Think about what AI makes possible for a solo developer or small team.

You can research ideas faster.

You can build prototypes faster.

You can create websites faster.

You can generate content faster.

You can test more ideas.

And most importantly, you can spend more of your time thinking about what people actually want.

The internet is full of complicated businesses.

But it's also full of incredibly simple websites solving incredibly specific problems.

And sometimes, that's exactly where the opportunity is.

The next website you build doesn't need to change the world.

It just needs to solve one problem really well.
