Turn Your Platinum Card Into
an AI-Powered Command Center
A step-by-step guide to connecting ERA Context and Claude to your AMEX Platinum — so you can track every benefit, optimize every dollar, and never leave money on the table.
What you'll need
Three things. That's it. If you have all three, you're ready to go.
AMEX Platinum Card
Active card with at least one billing cycle of transactions. This is the data source everything plugs into.
ERA Context
The financial MCP that connects your real account data to Claude. You'll set it up in Step 1.
eraapp.com ↗Claude Pro or Team
Claude reads your ERA Context data and builds your analysis. Free tier works for basic prompts, but Pro unlocks Projects and memory.
claude.ai ↗Install ERA Context and Connect Your AMEX
ERA Context is what gives Claude access to your real financial data — transactions, balances, spending categories — directly from your connected accounts. Think of it as the bridge between your AMEX Platinum and Claude's brain. Setup takes about 3 minutes.
American Express and select it from the results.
Now we connect ERA Context to Claude. This is where the magic happens.
ERA Context.
Now we get into the AI prompts — including a full dashboard builder you can paste into Claude and open directly in Google Chrome. This is where it gets good.
ERA Context uses bank-grade 256-bit encryption and read-only access. Claude only sees what ERA Context shares in a session — it doesn't store your financial data on Anthropic's servers. You can disconnect any account from ERA Context at any time.
Set Up a Claude Project for Your Card
Claude Projects (available on Pro and Team plans) let you create a persistent space where Claude remembers context across sessions. This means you don't have to explain your card setup every single time. Set it up once, use it forever.
AMEX Platinum Dashboard.You are my personal AMEX Platinum financial assistant. You have access to my ERA Context data which includes my American Express Platinum card transactions, balance, and spending categories. My card details: - Card: American Express Platinum - Annual fee: $895 - Primary use: Travel, dining, and maximizing MR points - 2026 credits to track: $600 hotel (FHR/Hotel Collection), $400 Resy dining, $300 digital entertainment, $300 lululemon, $300 Equinox, $200 Uber Cash, $200 airline fee, $200 Oura Ring, $219 CLEAR+, $155 Walmart+, $120 Uber One, $100 Saks (ends July 2026) My goals: 1. Track which of my annual/monthly credits have been used vs. remaining 2. Optimize my category spending to earn the most MR points 3. Get a monthly breakdown of where my money is actually going 4. Flag any subscriptions or charges I might have forgotten about When I ask about my spending, always pull from my connected ERA Context data. When giving advice, be specific to the AMEX Platinum benefit structure — not generic credit card advice. Always tell me if a credit has expired or is about to reset.
Without a Project, you'd have to re-explain your card setup in every new conversation. With a Project, Claude knows your card, your goals, and your preferences from message one. It's the difference between a generic chatbot and an actual financial assistant.
Run Your First Full Spending Analysis
Before running any analysis, paste this master context prompt into Claude first. It gives Claude a complete understanding of every single benefit and perk on your Platinum Card — so every answer it gives you is specific to your card, not a generic credit card response. Do this once per conversation or save it to your Claude Project instructions.

Copy this once and paste it at the start of any new Claude conversation about your card. Or add it directly to your Claude Project instructions (Step 2) so Claude has this context automatically every single time you open the project — no pasting needed.
Now run your first real analysis. This gives you a complete picture of last month — categories, totals, and anything worth flagging.
Pull my AMEX Platinum transaction data from ERA Context for the last 30 days. Give me: 1. Total spend amount 2. Breakdown by category (dining, travel, groceries, subscriptions, shopping, other) 3. Top 5 individual charges by amount 4. Any recurring charges over $20 that I might have forgotten about 5. A one-sentence verdict on whether this month looks healthy or needs attention Format it cleanly with dollar amounts and percentages per category.
Once you get the output, scan it for anything that catches your eye. Then use this follow-up to go deeper on any single category:
Break down my [category] spending in detail from last month. List every transaction in that category with: - Date - Merchant - Amount Then tell me: is this spending pattern normal, or is there anything I should reconsider?
Your Interactive Benefits Tracker
The AMEX Platinum has over $1,500 in annual statement credits — but only if you actually use them. Check off each benefit below as you use it. The tracker resets when you reload the page, so bookmark this guide or run the Claude prompt below to have Claude track it for you automatically.
Now use this prompt to have Claude automatically check which benefits you've actually triggered based on your real transaction data:
Look at my AMEX Platinum transaction history from ERA Context for the last 12 months. Cross-reference it against these AMEX Platinum 2026 annual credits: - $600 hotel credit (Fine Hotels + Resorts or Hotel Collection, $300 semi-annually via Amex Travel) - $400 Resy dining credit ($100/quarter at U.S. Resy restaurants) - $300 digital entertainment ($25/month: Disney+, Hulu, ESPN+, Paramount+, Peacock, NYT, WSJ, YouTube Premium) - $200 Uber Cash ($15/month Jan-Nov, $20 December) - $219 CLEAR+ membership - $200 Oura Ring credit (hardware at ouraring.com) - $200 airline fee credit (one selected airline, incidental fees) - $155 Walmart+ ($12.95/month) - $120 Uber One credit (auto-renewing membership) - $120 Global Entry (or $85 TSA PreCheck, every 4–4.5 years) - $300 Cruise Privileges Program (qualifying cruises via Amex Travel) For each benefit, tell me: 1. Whether I've used it (based on actual transactions) 2. How much of the credit I've captured vs. left on the table 3. The dollar value still remaining this year 4. A reminder of any that expire at year-end Then give me a total: how much credit have I actually used, and how much have I wasted?
The Spending Optimizer — Earn Max Points on Every Purchase
The AMEX Platinum's bonus categories are specific. Use this table as your cheat sheet for which card to reach for on each spend type, then run the Claude prompt below to get a personalized optimization plan based on your actual spending patterns.
| Category | MR Points Rate | Best card to use | Notes |
|---|---|---|---|
| Flights — booked directly with airline | 5x MR | ✅ Platinum | Up to $500k in purchases/year |
| Flights + Hotels via Amex Travel | 5x MR | ✅ Platinum | Use amextravel.com, not Google Flights |
| Resy restaurants (U.S.) | 1x MR + $400 credit | ✅ Platinum | $100/quarter Resy credit — always use Platinum here |
| Other dining (restaurants, delivery) | 1x MR | Consider Gold Card | Gold earns 4x — use Gold for non-Resy food |
| U.S. Supermarkets | 1x MR | Consider Gold Card | Gold earns 4x up to $25k/year |
| Uber (using Uber Cash) | Credit | ✅ Platinum | $15/mo auto-loaded — always use it |
| Hotels (non-AMEX Travel) | 1x MR | Hotel card or Amex Travel | Book through amextravel.com for 5x |
| Everything else | 1x MR | Use a 2x flat card | Platinum underperforms here |
Look at my AMEX Platinum spending from ERA Context for the last 3 months. For each spending category: 1. How much did I spend? 2. How many MR points did I earn based on the Platinum's actual bonus rates? 3. How many MORE points could I have earned if I'd used the optimal card for that category? 4. What's the estimated dollar value of those missed points? (use 1.8 cents per MR point as the estimate) Then give me 3 specific, actionable changes I should make to my spending habits to maximize MR points going forward. Be direct — tell me exactly which card to use for which category.
Your Monthly AI Dashboard Routine
This is the actual system. Four prompts, once a month, on the same day (I run mine on the first Saturday of the month). It takes about 15 minutes and it keeps your card working hard all year.
Run Prompt 1 (Monthly Spending Overview). Get the full picture. Check your top categories, flag anything weird, and make sure there are no forgotten subscriptions eating your budget.
Run Prompt 3 (Auto Benefits Audit). Find out which credits you've captured and which you've left on the table. Immediately fix anything expiring before month end.
Run Prompt 4 (Personalized Points Optimizer). See how many MR points you've missed by using the wrong card. Adjust your habits for the next quarter.
Run the full year audit below. This tells you whether your $895 annual fee is actually paying for itself — and gives you a number you can feel good about when the renewal hits.
Using my ERA Context data from the past 12 months, give me a complete annual value audit for my AMEX Platinum card. Calculate: 1. Total credits I've actually used and their dollar value 2. Estimated MR points earned and their dollar value at 1.8 cents/point 3. Any intangible benefits I've used (Centurion Lounge, Priority Pass, Global Entry, etc.) 4. Total value extracted from the card 5. Annual fee: $895 Then tell me: - Is the card net-positive for me this year? - What's my effective annual fee after credits? - What could I do differently next year to get even more value?
Build Your Own Interactive Dashboard
This is where everything comes together. Copy this prompt and paste it into Claude — because ERA Context is connected, Claude will pull your actual AMEX Platinum spending data, figure out which credits you've already triggered, calculate your real MR points, and then build a beautiful personal dashboard with all of it baked in. Your numbers. Your card. No coding required.
Paste the prompt into Claude → this one takes about 5 minutes to fully generate, so go grab a snack, make yourself some food, and come back — it'll be totally done waiting for you. Once it's finished, copy the HTML code it gives you → save it as amex-dashboard.html on your desktop → right-click the file and open it in Google Chrome. Done. You now have a personal dashboard you own forever.
I have ERA Context connected to my American Express Platinum card. Pull my real transaction and spending data from ERA Context right now and use it to build me a personal AMEX Platinum dashboard. STEP 1 — PULL MY DATA FIRST Before writing any code, retrieve the following from ERA Context: 1. My last 12 months of transactions on my AMEX Platinum 2. Total spend by category (dining, travel, groceries, shopping, subscriptions, entertainment, other) 3. Monthly spend totals for each of the last 12 months 4. Any recurring charges or subscriptions 5. Top 10 merchants by total spend 6. Which of my AMEX Platinum credits have been triggered based on actual transactions: • $400 Resy Dining — look for Resy restaurant charges • $600 Hotel Credit — look for Fine Hotels + Resorts or Hotel Collection bookings via Amex Travel • $300 Digital Entertainment — look for Disney+, Hulu, ESPN+, Paramount+, Peacock, NYT, WSJ, YouTube • $200 Uber Cash — look for Uber charges • $219 CLEAR® Plus — look for CLEAR membership charge • $200 Oura Ring — look for ouraring.com purchase • $200 Airline Fee Credit — look for incidental airline charges (bags, seat fees, etc.) • $155 Walmart+ — look for Walmart+ membership charges • $120 Uber One — look for Uber One membership Once you have all of that data, proceed to Step 2. STEP 2 — BUILD THE DASHBOARD Using ONLY my real data from Step 1, build me a beautiful single-file HTML dashboard I can save to my desktop and open in Google Chrome. Hard-code all my actual numbers directly into the HTML — this is a snapshot of my card, not a blank template. ────────────────────────────────────────── SECTION 1: MY YEAR AT A GLANCE (top of page) ────────────────────────────────────────── 4 big stat cards across the top: • Total spend this year (from my actual data) • Total MR points earned (calculated from my actual transactions using correct multipliers: 5x flights/hotels via Amex Travel, 1x everything else) • Estimated MR point value at 2 cents per point • Net ROI: total credits captured minus $895 annual fee (green if positive, red if negative) ────────────────────────────────────────── SECTION 2: SPENDING BREAKDOWN ────────────────────────────────────────── Left side: Doughnut chart showing my actual spend by category with dollar amounts and percentages Right side: Horizontal bar chart showing my top 10 merchants by total spend Both charts use Chart.js from: https://cdnjs.cloudflare.com/ajax/libs/Chart.js/4.4.1/chart.umd.min.js Use a warm color palette: purples, coral, gold, sage green ────────────────────────────────────────── SECTION 3: MONTHLY SPEND TREND ────────────────────────────────────────── Bar chart showing my actual spend for each of the last 12 months Highlight my highest month in gold Show month-over-month change percentage above each bar ────────────────────────────────────────── SECTION 4: BENEFITS CAPTURED vs. AVAILABLE ────────────────────────────────────────── For each AMEX Platinum credit, show: • Credit name and total available • How much I've actually used (based on my real transactions) • A filled progress bar showing % captured • Status badge: ✅ Fully Used / 🟡 Partial / ⚠️ Not Used Yet • At the bottom: total credits captured, total left on the table, net ROI ────────────────────────────────────────── SECTION 5: SUBSCRIPTIONS & RECURRING ────────────────────────────────────────── A clean table of all recurring charges found in my transactions: • Merchant, amount, frequency, whether it qualifies for any Amex credit ────────────────────────────────────────── DESIGN: ────────────────────────────────────────── • Dark background (#0a0a0a), card backgrounds (#111 and #161616), gold accent (#c9a84c) • Google Fonts: Bricolage Grotesque for headings, DM Sans for body, DM Mono for all numbers • Header: "AMEX Platinum — [my first name]'s Dashboard" + today's date • Fully responsive, works in Google Chrome • No inputs or sliders needed — all data is real and hard-coded from my actual account • Make it look like a premium fintech app Output the complete HTML as a single code block.
Bonus Prompt Library
Three extra prompts for specific situations you'll run into as a Platinum cardholder.
I'm planning a trip to [destination] from [date] to [date]. Based on my AMEX Platinum benefits, tell me: 1. Should I book flights directly with the airline or through Amex Travel? (5x either way — but any other considerations?) 2. Are there Fine Hotels + Resorts properties in [destination] that would trigger my $200 hotel credit? 3. Which Centurion Lounges or Priority Pass lounges are at my departure airport? 4. Do I have any remaining airline fee credits that apply to this trip? 5. How should I pay for each part of this trip to maximize MR points? Give me an action checklist before I book anything.
Look at my last 60 days of AMEX Platinum transactions from ERA Context. Find every recurring charge — subscriptions, memberships, auto-renewals. List them with: - Merchant name - Monthly or annual cost - When it first appeared - Whether it qualifies for any AMEX Platinum credits (entertainment, Walmart+, etc.) Flag anything over $20/month that I might want to reconsider. Also flag anything that looks like a free trial that auto-converted to a paid plan.
Compare my AMEX Platinum spending from ERA Context between last month and the month before. Show me: 1. Total spend: up or down by how much? 2. Which categories increased the most? 3. Which categories decreased? 4. Any new merchants this month that didn't appear last month? 5. Did I earn more or fewer MR points compared to last month? Give me a one-paragraph summary of what changed and why it might matter.
Your AMEX Platinum is now a tool, not just a card.
The average Platinum cardholder captures less than 60% of available credits each year. With ERA Context and Claude running your monthly audit, you're in the top tier — actually squeezing the value out of a $895 card. Run the routines. Check the prompts. And if you find something I missed, drop it in the community.
