What ATHENA is, and what it isn't

Built for thoughtful choices

Use it to compare courses, software, training programs, project approaches and similar options. You choose the evidence sources and give the ratings. The same inputs produce the same scores.

Not a verified recommendation engine

ATHENA does not verify providers, check live prices, guarantee income, make hiring decisions or give financial, legal or medical advice. Its calculations express your own priorities.

Before you purchase

How much does the toolkit cost?

€9.90, charged once through Stripe. There is no ongoing subscription.

Do I need an online account?

The workbook itself runs as a local HTML file once downloaded; it does not require an ATHENA account. The purchase is processed by Stripe.

How is the digital file delivered?

The existing Stripe checkout redirects to a downloadable ZIP page after payment. That download address can currently be shared; it is not an individually authenticated buyer portal. Please do not treat the link as confidential storage.

Does it work in German and Turkish?

The workbook interface is currently in English. The package includes instructions in English, German and Turkish. The main website is English-first; optional German and Turkish guides are linked in the navigation.

What about cancellation and consumer rights?

Review the merchant's published terms and withdrawal information before ordering digital content.
