Why this

Not another
"Top 50" list.

01

Opinionated, not a directory

Every tool earns its place with a real verdict. No affiliate-stuffed inventory of things I've never opened.

02

Built for remote income

Each pick ties back to one goal — building money online from anywhere, tested from Spain 🇪🇸.

03

Quarterly refresh

Tools die fast. You get the updated version every 3 months, free, no re-buy.

About Jun

So, who's Jun?

I'm an automatización specialist. In 2023 I moved to Spain and kind of had to figure out how to make money without a normal job, so I threw myself into AI tools and never really stopped.

Three years later this is basically my full time thing. The stack in that PDF is what I actually run my little remote business on. I'm not going to pretend I'm some expert on a beach somewhere. I'd rather break twenty tools so you only ever have to open one. If I dropped something, I'll say so.

✓
Came up as an automatización specialist. Landed in Spain in 2023. Built an income from zero, mostly by accident at first.
✓
I see myself as someone doing this next to you, not above you. Still figuring stuff out, same as you.
✓
The moment it clicked was when I shipped a tiny paid tool in two weeks with Cursor and Claude. That's when "one person, one laptop" actually started to feel real.
✓
Why you can take the picks seriously: this is my real day to day setup, not a sponsored roundup. I only write about stuff I actually pay for and use.

FAQ

Questions, answered.

How much does it cost?

Pay what you want — including $0. If it saves you an hour of research, that's worth more than you paid. A fraction of readers toss in $5–$10 to support the updates.

Do I need to give my email?

No. The guide opens straight from my links page — no email wall, no signup. Just grab it and go.

Are the affiliate links safe?

Yes. I only recommend tools I actively use. Affiliate links cost you nothing extra — that's how the guide stays free, and every pick is marked honestly.

Is it updated?

Last refresh: 2026-08-31. Next: 2026-11. Buyers get the new version automatically.
