Turn a Screenshot or Design Reference into a Working Mobile App

Takes your screenshot, design file or detailed description and builds a fully working iOS or Android app that matches it: design analysis, component inventory, every screen, navigation wiring and interaction checks.

Role: you are a senior Android and iOS developer who turns any visual reference into a production-ready app, faithful to the pixel and fully functional.

Task: study the design reference or screenshot I give you, then build a working mobile app that reproduces every visual and interaction detail exactly.

Steps:
1. Before starting, ask me to share the screenshot, the design file or a detailed description, plus my target platform.
2. Analyze every visual element and extract the layout, the components, the navigation patterns, the color system and the typography.
3. Map every user flow: list all the screens, transitions and interaction points, whether they are visible or only implied by the design.
4. Build each screen with the exact spacing, colors, fonts and component behavior of the reference.
5. Connect all the screens through navigation, using the transitions and gestures that suit the platform.
6. Test every interaction and confirm that each tap, swipe and input behaves the way the design suggests.

Rules:
- Fidelity to the design cannot be negotiated: any deviation from the reference needs my explicit approval before you continue.
- Raise any ambiguous design decision right away instead of guessing in ways that would lead to costly revisions.
- Build every component as a reusable element so that all screens stay consistent.
- Respect platform conventions even where the reference does not mention them.

Deliver the build in stages, in this order:
analysis of the design → inventory of components → screens built → navigation wired → interactions tested → the production-ready app

7-Day No-Code Stack and Build Plan for Your Software IdeaNewApp BuildingPicks a full no-code stack for the software you want to build in 7 days: the tool for each component, why the mix beats alternatives for your case, the build order step by step and the paid-worthy feature set you can launch by day 7.
Role: you are a specialist in no-code software stacks.

Goal: within 7 days, build [type of software] with no-code tools only.

Lay out the full stack:
1. The specific tool that handles each component.
2. Why this combination beats the alternatives for my use case.
3. The build sequence, step by step.
4. The realistic feature set ready at launch on day 7 that people would genuinely pay for.
AI Chat Mobile App with Multiple Models and Streaming RepliesNewApp BuildingBuilds a complete AI chat app for mobile with a dark interface: chat screen, model and provider settings, saved conversations, word-by-word streaming replies and a builder for custom system prompts and personas.
Role: you are a senior mobile developer who specializes in AI conversational interfaces, with support for several models and an enterprise-grade chat architecture.

Task: create a complete app for chatting with AI. It needs conversation management, support for multiple models and a refined dark UI that looks and feels native on any device.

Steps:
1. Before starting, ask me for my preferred AI provider, the endpoint configuration, the app name and any specific features I want.
2. Build the main chat screen: message bubbles, an input field, an indicator of the active model and the conversation history.
3. Create a model configuration screen where users switch between providers and adjust the parameters.
4. Build conversation management so users can create, name, organize and delete chat sessions.
5. Add streaming so the AI's reply appears one word at a time instead of all at once.
6. Add a system prompt builder that lets users create custom AI personas for different uses.

Rules:
- Dark interface everywhere; no light mode option unless I explicitly ask for it after the first build.
- Message history persists between sessions without user login and without cloud storage.
- On a slow connection, streaming degrades gracefully, with no lost message content and no corrupted history.
- Every API error is shown to the user as a helpful message, never as a technical error code.

Deliver the build in stages, in this order:
chat interface → model settings → management of conversations → streaming engine → system prompt builder → the full app
AI-Powered Browser Tool: Feature, Prompt Architecture and PricingNewApp BuildingDesigns a browser-based tool that adds AI to a workflow you choose: the AI function that feels almost magical for that use, the prompt architecture behind the core feature, an interface non-technical users can handle and pricing that justifies paying instead of using ChatGPT directly.
Role: you are a specialist in AI-powered browser tools.

Goal: I want to bring AI capabilities to [specific workflow] through a tool that runs in the browser.

Design the tool in four sections:
1. AI function: the specific thing the AI does that makes the tool feel truly magical for this use case.
2. Prompt architecture: how the prompts behind the tool's core feature are structured.
3. Interface: a user interface that makes the AI approachable for people with no technical background.
4. Pricing: a price that makes my tool feel worth paying for compared with simply using ChatGPT directly.

Build a Small App with Claude Code in 6 Phases, from Plan to Launch6 phasesNewApp BuildingTakes a simple app idea to a finished first version with Claude Code in six phases: a scoped build plan, a minimal version 1, error fixing with small safe changes, one feature at a time, a product-design review and a prioritized launch checklist.
  1. Phase 1 — Scoped build plan
    I want to create a simple app starting from nothing.
    
    - App idea: [app idea]
    - Who will use it: [target user]
    - What it should help them achieve: [what the app should help them do]
    - Core features: [3 to 5 simple features]
    - Preferred tech: [React / Next.js / plain HTML, CSS and JS / your choice]
    
    Before you write any code:
    1. Ask me any questions that matter for the build.
    2. Then draw up a simple build plan that covers the pages, the components, the data structure and what version 1 includes.
    
    Version 1 must stay small. I want an app that works before we add any advanced feature.
  2. Phase 2 — Version 1 only
    Following the plan we agreed on, build version 1 and nothing more: the smallest version of the app that works.
    
    Requirements:
    - the app loads
    - the main feature works
    - the design is clean enough to test with
    
    Leave out login, payments, a database, notifications, admin dashboards and every other advanced feature, unless one of them is truly essential.
    
    When the build is done, run the project, look for errors and fix whatever is broken.
  3. Phase 3 — Fix the errors
    Run the app and examine the error.
    
    1. Explain in plain English what is broken.
    2. Fix it with the smallest change that is safe.
    3. Run the project once more and confirm the app is working.
    
    Do not touch files unrelated to the problem unless the fix requires it.
  4. Phase 4 — Add one feature
    Next feature to add: [feature]
    
    - Before you write code, tell me which files you will modify and why.
    - Once the code is written, test the app and check that the existing features still work.
    - Keep the design in line with the current app and do not make the structure more complicated.
  5. Phase 5 — Product-design review
    Look at this app the way a product designer would and tell me:
    - what feels confusing
    - what should be taken out
    - what should be made clearer
    - what a person using it for the first time would miss
    - what would make the app more useful
    
    Then improve the interface without making it complicated. It must stay clean, simple and easy to understand.
  6. Phase 6 — Launch checklist
    Before launch, draw up a checklist for this app. Look for:
    - broken pages
    - errors in the console
    - layout problems on mobile
    - copy that is confusing
    - missing empty states and loading states
    - basic accessibility issues
    - anything else that makes the app feel unfinished
    
    Sort the issues from most to least important, then fix the top ones first.
