$1000+ in AI Passive Income Selling Voice Clone

AureliathepandaAI Voice Actor $1000+ in 5 months

Recently posted on Reddit…

I earned just over $1,000 in 5 months by selling my AI voice on the ElevenLabs Voice Library.

Other people use your AI voice clone in projects like audiobooks, videos, and more.

You get paid passively for every 1,000 characters generated using your voice.

Requires a Creator plan ($22 at 50% off the first month, which can be downgraded to $5 after the clone is uploaded) and 30–180 mins of good-quality audio.

Not a “get rich quick,” but with a decent mic and some time, it’s a legit AI side hustle.

More info in the post, and here’s the link to ElevenLabs.

$3 Million Potential For This Exploding Idea?

Eric from Exploding Ideas writes…

Right now, there’s a blazing chance to cash in on the meteoric rise of wake windows, with global search interest hitting 100 on Google Trends in 2025.

A wake window is how long a baby can stay awake before needing sleep. It’s a big deal for parents looking to keep their kids rested and happy

Eric has a few ideas for cashing in on this trend, including…

A wake window app with a freemium model—$5/month for premium tracking, 10K users nets $530K yearly profit after $70K costs. Add AI predictions for extra oomph.

A sleep consulting gig in Utah or North Carolina—$150/session, 50 clients/week brings $432K annual profit after $10K marketing. Bundle digital guides for $20 a pop.

A franchise blending app, consulting, and sleep gear sales, targeting hotbeds like Australia and Canada—scale to 5 hubs for $3M revenue in 3–5 years.

The Perfect Business Opportunity For Vibe Coders

Ian Nuttall tweets a demo of a Chrome extension he built and writes…

chrome extensions are just perfect for vibe coders to use ai to build utility apps (and saas too)

– cursor is very good at building them (gemini & claude)
– super easy to test them locally
– built in distribution via the chrome web store
– so many old manifest 2 extensions you can rebuild
– easy to find contact info to acquire competitors

i built this tool in one shot… thinking it could be part of a much larger helper tool to write posts, find content ideas, run better giveaways, create carousels etc

sometimes vibe coding to scratch your own itch can give you plenty of ideas for your next biz

Rohit Lakhotia chimes in…

Vibe coded a Chrome extension that converts all currency on a webpage to your local currency with real-time forex rate…

All done in less than an hour using Cursor.

They Cashed in on This Trend and Earned $2.8 Million

Museum HacksTours company $2.8 Million revenue

The Growth Signal reports

Consumer interest in ‘third spaces’ spiked in early 2023—a response to lockdowns and social isolation.

This wasn’t a temporary reaction. Instead, a fundamental shift in how people seek connection.

What are third spaces?

They aren’t your home (first space) or work (second space) but a (third space) where people gather, socialize, and build community. Classic examples include:

– Parks
– Libraries
– Museums
– Coffee Shops

An increasingly popular kind of third space in Ireland: men’s sheds

Some ideas to cash in on this trend…

A directory site of third spaces, categorized by location, vibe, activities, etc.Start a service hosting recurring events in third spaces (eg. coffee shop coworking)Copy what Museum Hacks ($2.8M rev) did in other cities.Newsletter focusing on third spaces in your local area.YouTube channel focusing on third spaces in your local area.

$1316 Earned From The Best User Research Website

Zain AzharUser Research Participant $1316 earnings

Zain Azhar posts on Reddit…

$6,000 in Side Hustle income for 2024: what works and what doesn’t

He attaches a screenshot showing he earned $1316 from UserTesting.com…

This is in my opinion the best website for participating in user research. The sign up process is extremely easy and they ask some basic information about yourself to start receiving surveys…

Each of these surveys range from $4-$90. The $4 and $10 surveys are simple and take 10 minutes to complete and ask you to record your audio only. The $30-$90 surveys require you to set up a time with the company to walk through a product demo and questions. These surveys take 30-90 minutes to complete so the hourly rate is still pretty high.

The only caveat with this is that you will not qualify for all of these surveys… you will qualify for around 1 out of every 6 surveys but since you can apply extremely quickly, you don’t waste much time on surveys you do not qualify for.

$1.75M Funding Hints at Huge Potential Business Opportunity

RecessOnline Marketplace $1.75 Million funding

From the latest Gaps report

Recess is an online marketplace for parents and carers to find after-school activities for their children to take part in.

The company, which raised a $1.75m pre-seed, is first launching in Austin, Texas and looking to branch out from there…

There’s a ton of search traffic up for grabs – especially when they start expanding to more locations.

Whenever I report on a business that’s starting out with one area of focus, I can’t help but think there are other cities and countries people could start building a similar model for before them.

Of course, you’ll have to have the passion for the idea and see potential in the region you’ll target.

$5K/Month Upwork Arbitrage Opportunity (With AI)

A recent video from Jesse Cunningham…

$5,000/Month with ONE ChatGPT Prompt (Replit + UpWork)…

He doesn’t actually show that he earned $5K but his process is sound

First…

Go to ChatGPT and ask it: give me a list of keywords to type into Upwork to find jobs that easily can be done with AI code and tools like Replit.

Get ChatGPT to shortlist the jobs, pick one, then copy/paste the job description into ChatGPT and get it to create a prompt for Replit.

Spend a few minutes building a demo in Replit – easier than it sounds – then send that to the client along with a screencast

That should help you stand out from other proposals.

What you’re trying to do here is to get your foot in the door and build relationships with really good people… We can make a lot of money, but you’ll make more money if you do a good job and… earn people’s trust
