These terms apply to purchases of digital products from Decodes Future at decodesfuture.com (“we”, “us”). Please read them before you buy. By completing checkout you agree to them.
1. Who you are buying from
Decodes Future is the trading name under which this digital publication is sold. For any question about your order, your files, a refund or these terms, contact omar@decodesfuture.com. We aim to reply within two business days.
2. What you are buying
AI Made Useful — The Complete AI Encyclopedia (Digital Edition) is a digital publication delivered as downloadable files. Your purchase includes:
- The complete 445-page book as a PDF;
- An EPUB edition for e-readers, phones and tablets;
- A Markdown (plain text) edition with its images;
- The Project Workbook containing six companion worksheets.
The 100 prompt cards and 25 worked conversations are contained within the book itself and are not separate products.
Your purchase does not include a physical book, a subscription to ChatGPT or any other AI service, personal tuition, support with third-party software, or any guarantee of a particular outcome, income or skill level.
3. Price and payment
The price shown at checkout is the price you pay, in US dollars. Payment is processed by Stripe; we never see or store your full card details. The current launch price of $49.99 replaces the list price of $99.00 and may end at any time without notice. Any applicable tax is shown before you confirm payment.
4. Delivery
Delivery is immediate and automatic. Download links appear on the order confirmation screen as soon as payment is authorised, and the same links are emailed to the address you gave at checkout. Links do not expire and there is no limit on how many times you may download your files.
If your files do not arrive, first check your spam or promotions folder, then email omar@decodesfuture.com with the email address you used. We will resend them.
5. Refunds
You may request a full refund for any reason within 60 days of purchase. See our Refund Policy for the details. Nothing in these terms limits any statutory rights you may have under the consumer law that applies where you live.
6. Your licence to use the book
When you buy, you receive a personal, non-exclusive, non-transferable licence to read and use the files for your own private purposes, on any devices you own. You may print a copy for your own use.
You may not resell, republish, upload, share publicly, distribute, or make the files available to anyone else, and you may not use the text to train a machine-learning model. The work remains the copyright of its author.
7. Independence and accuracy
This is an independent publication. It is not affiliated with, authorised by or endorsed by OpenAI, Google, Meta or any other tool provider, and any trade marks mentioned belong to their owners.
AI tools change their features, limits, prices and interfaces frequently. The book was prepared in September 2026 and teaches methods rather than a fixed set of buttons; always check a provider’s current official instructions for your own account.
8. No professional advice
The book teaches general methods for organising information and preparing better questions. It does not provide personalised medical, legal, financial or safety advice, and it is not a substitute for a qualified professional. In an emergency, contact the appropriate local emergency service directly.
9. Liability
We provide the book in good faith and take care over its accuracy, but we cannot accept liability for decisions you take as a result of reading it, or for the output of any third-party AI service. Our total liability to you in connection with your purchase is limited to the amount you paid. Nothing here excludes liability that cannot lawfully be excluded.
10. Changes
We may update these terms. The version that applies to your purchase is the version published on the day you bought. Material changes will be reflected in the “last updated” date above.
