Research · Composition · Working UX

Don't just make
it look good.
Make it work.

Choose the kind of website or app you are building. Understand which sections belong, why they appear in that order, which skills to use, and what to test. Inspect an original interactive preview before copying a complete design, build, or audit prompt.

Research-linked guides, original visual studiesNO REQUIRED PAID TOOLS · NO FALSE PROOF
Go deeper into individual decisions.

200 additional website and app patterns with original interactive previews, research caveats, open-source references and complete prompts.

WHY THIS STRUCTURE

Section / screen order

    Copy-ready prompt system

    Design first, build the real interactions second, then critique with evidence. These prompts include each step's placement, skill, states and tests.

    EDITABLE STARTER PROMPT
    02 / OPTIONAL CRAFT MODULES

    The right tool.
    Not every tool.

    Add AI, animation, 3D, payments and other capabilities only when they support a real user task. Each module includes when to use it, a starting approach and a research or documentation link.

    03 / RESEARCH & SOURCE ATLAS

    Show your
    working.

    Primary platform guidance, UX research, peer-reviewed work and implementation references. Every source tells you what it supports and what it does not prove.

    04 / REUSABLE OPEN SOURCE

    Study the craft.
    Respect the license.

    Browse upstream projects. The previews and prompts in this academy are original studies; the MIT license for Prompt-Vault does not override upstream code, asset, model or commercial licensing.

    License notes are a starting point, not legal approval. Check each upstream repository and specific package or media asset before reuse.

    05 / APP BUSINESS RESEARCH

    Revenue is real.
    Correlation isn't causation.

    Sensor Tower's State of Mobile 2026 identifies the top three non-game apps by 2025 worldwide in-app purchase revenue. Analyze possible product patterns without copying or claiming that UI alone produced their earnings.

    What subscription economics teach the design

    RevenueCat State of Subscription Apps 2026 tracks more than 115,000 subscription apps using its platform. These are observational benchmarks, not forecasts or causal experiments.

    ONE LAST RULE

    Prototype. Test.
    Tell the truth.

    Real usability, accessibility, revenue outcomes and store compliance require evidence. Use these guides to structure work, then verify with real people, browsers and devices.
