hey there! πŸ‘‹

so by now, you probably already know that AI is great 😎

In fact, it can help you do things like:

with AI you can

Automate your marketing βš™οΈ 

with AI you can

Grow your income faster πŸ’°

with AI you can

Save time on manual work 🧠

and a lot more...

But the big problem is this:

It's getting too 

complex ❌

(and it's not getting better)

Issue #1

Over 2,124 new AI tools created just in October 2023 alone...

Issue #2

Each new tool requires a new knowledge-base and new skills to use...

Issue #3

... only to end up paying hundreds of $$$ per month for tons of software.

There needs to be a better way.

The idea:

What if you could get all best AI tools in one place?πŸ‘‡

instead of:

paying many subscriptions and having to manually understand each tool

short version: 

one hub with all AI tools.

πŸ‘‡ πŸ‘‡ πŸ‘‡ 


With Sintra Hub, you can automate over 30+ areas of your business with simple AI tools.

πŸ‘‰ One reason why Sintra Hub can do this is because it uses different API plans for each and distributes the cost, leaving you with a more efficient and easy bill.

πŸ’‘ Instead of many subscriptions, you can keep one – and just use a simple interface to navigate all the tools.

βœ… That's why you get all the best parts – without many of the drawbacks of having to manage dozens of tools.
