Example Prompts for Claude
Portfolio Deep Dive
Pull my complete asset allocation across all my Ally Bank accounts and break it down by asset class, sector, and geography. Format the results as a table with dollar amounts and percentages for each category.
Fee Audit
Calculate the total expense ratios, advisory fees, and any other costs I'm paying across every fund and account in my Ally Bank portfolio. Show me the dollar amount per year for each fee layer and the cumulative impact over 10 years assuming 7% annual growth.
Retirement Readiness
Run a retirement readiness analysis using my current Ally Bank balances, contribution rate, and historical savings trajectory. Model three scenarios — conservative, moderate, and optimistic — and tell me at what age each scenario runs out of money. Present the results as a comparison table.
Stress Test
Stress-test my entire Ally Bank portfolio against a 2008-style market crash, a 2020-style rapid drawdown, and a sustained stagflation environment. Show projected drawdown percentages and estimated recovery timelines for each scenario.
Tax-Loss Harvesting
Identify every tax-loss harvesting opportunity in my Ally Bank taxable accounts. For each position with an unrealized loss, estimate the tax savings at a 24% federal bracket and suggest a replacement holding that maintains similar sector exposure.
Cash Flow Analysis
Analyze my spending and cash flow from my Ally Bank transaction history over the past 6 months. Categorize expenses into fixed, variable, and discretionary. Calculate my savings rate and flag any months where I spent more than I earned.
Rebalancing Plan
Compare my current Ally Bank portfolio to a standard 60/40 target allocation and to a three-fund lazy portfolio. For each comparison, show me where I'm overweight and underweight, and recommend specific rebalancing moves with dollar amounts.
Holdings Review
Review my top 10 holdings by portfolio weight and run a fundamental analysis on each — P/E ratio, dividend yield, 52-week performance, and analyst consensus. Flag any positions where concentration exceeds 10% of my total portfolio.
Account Overlap Check
Analyze the overlap between my Ally Bank brokerage account and my retirement accounts. Identify any duplicate holdings, correlated positions, or sectors where I have unintentional concentration risk across accounts.
Financial Dashboard
Summarize my complete financial picture across all connected Ally Bank accounts — total net worth, investment performance over the past 1, 3, and 5 years, total fees paid last year, and my current savings rate. Format this as an executive financial dashboard.
Why Truthifi?
Security
Your Ally Bank username and password never touch Truthifi's servers. Authentication occurs directly on your provider's domain, creating a read-only, protocol-enforced connection secured with AES-256 encryption. Claude receives only scoped data tokens, never your actual credentials. You maintain complete control and can revoke access anytime at Ally’s connected apps settings or through your Truthifi dashboard.
Privacy
Your financial data stays under your complete control when using Truthifi. We never store login credentials from Ally Bank or any financial institution. You decide which specific accounts Claude can access, creating selective permissions rather than blanket access. Data never gets sold to third parties, and connecting one AI tool doesn't automatically grant access to others.
Audit Trail
Every MCP data request is logged with complete session details for Claude financial planning transparency. When Claude accesses your Ally Bank account data, the timestamp and specific information retrieved gets recorded automatically. You maintain full visibility into which financial details were accessed during each interaction. This tracking means you always know exactly what happened with your sensitive financial information.
Data Quality
When Ally Bank delivers raw transaction data with unified Ally Invest brokerage and high-yield savings history, Truthifi rebuilds historical information from multiple aggregation sources to correct these inconsistencies. Our normalization process fills data gaps and resolves ticker mismatches that could mislead Claude financial planning algorithms. This process delivers up to 10 years of clean, accurate transaction history for reliable analysis.

Frequently Asked Questions
Is it safe to connect my Ally Bank account using Truthifi?
Connecting through Ally Bank's OAuth 2.0 flow ensures your login credentials stay exactly where they belong: on Ally Bank's own secure servers. When you connect, you're redirected to Ally Bank's domain to log in directly, then grant specific read-only permissions before returning to Truthifi. Your username and password never pass through our systems. Claude receives only a scoped data token with read-only access, meaning it cannot move money, execute trades, or modify account settings. Every data request is logged for transparency, and you maintain full control through Ally’s connected apps settings or our dashboard. Complete security details at https://truthifi.com/security.
What does Truthifi allow with my Ally Bank data — and what does it block?
When you connect Claude to financial accounts, the AI cannot move money, place trades, or change account settings due to architectural limitations. The read-only access token from OAuth 2.0 flow prevents Claude from executing any transactions on your Ally Bank account. Instead, Claude personal finance capabilities focus on surfacing your fee burden across funds, flagging allocation drift from your target, and modeling retirement scenarios using your actual contribution rate. Financial advisors provide guidance based on your full financial picture, while AI analysis supplements your understanding between professional meetings.
What about my financial advisor?
The relationship between Ally Bank advisors and Claude creates a support system for your financial planning needs. Your advisor sets strategy and provides personalized recommendations, while Claude helps you stay informed between meetings by reviewing holdings, tracking allocation drift, and running what-if scenarios on your actual data. AI analysis supplements — but does not replace — professional guidance.
What Ally Bank account types does Truthifi support?
Truthifi supports connecting your Ally Bank savings, checking, CD, or Ally Invest brokerage accounts through its read-only MCP connector. Each account type is linked with the same security architecture — no trading, no transfers, no changes to your Ally Bank settings. You can connect multiple account types simultaneously for a complete financial picture.

How do I disconnect Claude from Truthifi?

Check your investment performance, run AI stock analysis, review fees across accounts, model retirement scenarios, or simply ask Claude to explain what changed since last month.
Because the data refreshes automatically using Truthifi's read-only connector, every answer reflects your current balances, holdings, and transaction history — not a snapshot from days or weeks ago. Whether you manage a single brokerage account or coordinate across multiple financial institutions, the combination of Claude and Truthifi puts real portfolio intelligence when you need it.
As Claude evolves, the financial insight it can extract from your Ally Bank data will only deepen. This connection puts you closer to your own financial data.

You stay in full control of what data is shared and can revoke access at any time through your account settings.
The result is financial transparency without financial risk — your data, your questions, on your schedule.
Congratulations! With your Ally Bank account now connected through Truthifi, Claude can analyze your real portfolio data in real time. Track your investments, review your fees, and ask questions about your actual financial accounts. Your data flows using Truthifi's read-only MCP connector — Claude can see your data but cannot make trades, move funds, or alter your account settings in any way.
Start with a simple question like 'What is my current asset allocation?' or 'How have my investments performed this year?' to see the connection in action. From there, you can explore deeper analyses specific to your financial goals. As you continue using Claude with your Ally Bank data, you may discover patterns in your spending, identify underperforming holdings, or find opportunities to reduce fees across your portfolio.
Each conversation builds on the last, giving you progressively richer financial awareness. The more questions you ask, the more value this connection delivers.
