Mega Prompt — Copy & Paste into AI
You are a world-class senior engineer with 20+ years of production experience. You have shipped systems used by millions of users worldwide. You write clean, scalable, secure, production-ready code with zero placeholders. You build personal finance apps that users love. Build a COMPLETE expense tracker app. Interview me first: 1. Platform target? (iOS + Android via Expo, web, both) 2. OCR provider? (GPT-4 vision, Claude, Textract, Google Vision) 3. Category taxonomy? (default + user custom) 4. Bank sync? (Plaid, SaltEdge, manual only) 5. Multi-currency support? 6. Splitting expenses with others? 7. Budgets and alerts? 8. Reports? (monthly, category, vendor, tax-ready exports) 9. Auth and security (biometric lock?) 10. Free vs Pro features and billing STACK: Expo + Next.js (web), Supabase for backend with RLS, OpenAI / Claude for OCR + categorization, Tremor for charts, RevenueCat for IAP, Plaid optional. AFTER MY ANSWERS: A. Show me a PROJECT PLAN: stack, file tree, data models, key flows, dependencies. B. Ask: "Does this look correct? Anything to add or change?" C. After I confirm, generate the COMPLETE project — every file in full, no TODOs, no placeholders, no shortcuts. Include configs, env examples, README, and run instructions. D. Add error handling, input validation, logging, and a sane test setup where applicable. E. Output files one at a time with clear file path headers so I can copy each into my IDE.

About this FinTech Prompt
The AI Expense Tracker with Receipt OCR is a battle-tested mega prompt designed for the Expense Tracker stack. Instead of dumping a vague request into ChatGPT or Claude, this prompt turns the AI into a senior engineer that interviews you first, confirms an architecture plan, and only then writes the full project — files, folders, configs and all. The result is production-ready code you can drop straight into a real build, not a half-finished snippet you still have to glue together.
You can paste this prompt into ChatGPT, Claude, Gemini, Copilot, DeepSeek, Mistral Le Chat or any modern reasoning model. It is written to be model-agnostic and stack-aware, so the AI adapts its output to your specific requirements rather than forcing a one-size-fits-all template on your project.
What you'll get
- OCR
- AI
- Personal Finance
How to Use the AI Expense Tracker with Receipt OCR
- Copy the full prompt from the box above using the "Copy Prompt" button. The clipboard copy includes every instruction the AI needs — do not trim it.
- Open your AI assistant — ChatGPT, Claude, Gemini, Copilot or any LLM with a large context window. Start a new conversation so previous chat memory does not pollute the build.
- Paste the prompt and hit send. The AI will ask you a structured set of discovery questions about your Expense Tracker project — features, screens, auth, payments, design style and target users.
- Answer in plain English. You do not need to know technical jargon. The AI translates your answers into the right architecture, libraries and folder structure.
- Confirm the plan. The AI will reply with a detailed project plan: file tree, data models, key flows. Approve it or ask for changes before code generation starts.
- Receive complete code. Every file is written out in full — no TODOs, no placeholders, no "implement this later" comments. Drop it into your IDE and run.
Why this Prompt Outperforms a Plain Request
Most developers write prompts like "build me a fintech app" and get back generic, half-broken boilerplate. The AI Expense Tracker with Receipt OCR works better for three concrete reasons:
- Role priming — the AI is told to act as a senior engineer with 20+ years of production experience in Expense Tracker, raising its quality baseline.
- Mandatory interview step — the AI must ask requirements before writing code, so you get a tailored project instead of a generic template.
- Plan-then-build flow — architecture is approved before code is generated. This eliminates the most common failure mode of LLM coding: building the wrong thing beautifully.
- Completeness contract — the prompt explicitly forbids placeholders, TODOs and stubbed functions. Every file you receive is meant to compile and run.
Frequently Asked Questions
Is the AI Expense Tracker with Receipt OCR free to use?
Yes. Every prompt on AI Prompts Lib is 100% free, no signup or paywall. Copy it, paste into your AI of choice, and start building. We do not log your inputs or your generated code.
Which AI models work best with this prompt?
This prompt is tuned for any modern large-context model: Claude 4 / 4.5 Sonnet, ChatGPT-5 / GPT-4 Turbo, Gemini 2.5 Pro, DeepSeek V3 and Copilot Chat. For very large projects we recommend Claude or Gemini because of their larger output windows.
Can I modify the prompt for my own use case?
Absolutely. Treat the prompt as a starting template — add your brand voice, swap the tech stack hints, or pin specific libraries you already use. The interview + plan + build structure is the magic, not the exact wording.
What if the AI's output has bugs?
Paste the error message back into the same chat and say "fix this and re-emit the affected files in full". Because the prompt forces complete file output, the fix slots straight back into your project without manual stitching.
