HUMAI currently sells the five digital downloads below through its Gumroad storefront. This catalog records what each live product listing says, without repeating ratings, testimonials, earnings promises, or performance claims.
Availability note: HUMAI checked the five destination pages on 18 July 2026. Each returned a live product page. Prices and files can change, so confirm the listing and checkout terms before paying.
Image generation prompt collection
The Gumroad page for Ultimate Collection of High-End Prompts for AI Image Generation describes a downloadable PDF with more than 50 image prompts and visual examples. It displayed a price of $19.99 during the availability check.
The product page names several image models. Model behavior and prompt syntax can change, so buyers should treat the material as a prompt collection, not a guarantee of a particular visual result.
AI income idea guide
The Ultimate Guide to Making Money with AI presents more than 100 business and freelance ideas. At the time of review, its purchase page displayed $4.99.
The sales page still refers to a 2025 edition and contains claims that HUMAI has not independently substantiated during this recovery. Treat the download as an idea list. It does not promise revenue, profit, demand, or legal suitability.
Prompt engineering playbook
The listing for Prompt Engineering for AI: ChatGPT and Midjourney Playbook describes a PDF covering prompt structure, iteration, templates, safety, and workflow examples. A $4.99 price appeared in the checked page metadata.
Product interfaces and model capabilities change. Check whether the examples still match the tools and plans you use before applying them to paid work.
Marketing prompt collection
100+ AI Prompts for Marketers groups downloadable prompts around content, email, search, advertising, analytics, and idea development. The checked listing priced the collection at $4.99.
The listing describes prompts and examples, not measured campaign outcomes. Any draft produced with the collection still needs brand, factual, legal, and channel review.
UI and UX prompt collection
Gumroad describes 100+ AI Prompts for UI/UX Designers as a downloadable set organized by design tasks and use cases. The storefront displayed $4.99 when HUMAI checked it.
The collection can supply starting points. It does not replace user research, accessibility checks, product constraints, or design validation.
Purchase and evidence boundaries
These are HUMAI products, so a purchase supports this publisher. Product descriptions come from HUMAI's Gumroad listings. Their presence in this catalog is not an independent review or a claim that a download will produce a financial, creative, or productivity result.
Read the current Gumroad listing before purchase. Use the seller and platform terms for delivery, taxes, refunds, and support. HUMAI should revise or remove a catalog entry if its destination stops resolving or its description no longer matches the delivered file.
