Searching for "ChatGPT First Horizon"? You're in the right place. Your First Horizon account holds the day-to-day mechanics of your Southeast financial life: checking balances, savings goals, money market deposits, CD ladders, IRA contributions, mortgage payments, and wealth management positions. Until now, getting "AI for First Horizon" meant exporting CSVs from Memphis-region online banking, copying numbers into spreadsheets, and hoping the figures stayed accurate by the time you asked ChatGPT a question.

By Scott Blandford, Founder & CEO of Truthifi | Reviewed by Mike Young

Truthifi changes that. With a ChatGPT First Horizon connection through Truthifi, ChatGPT can see your live First Horizon balances, transaction history, CD maturity schedule, and wealth management positions. Truthifi rebuilds your historical data on connection: it fills gaps, corrects categorization errors, and resolves merchant naming mismatches, so ChatGPT works with clean, normalized data from day one. All of this happens through a read-only MCP connector that never touches your credentials and cannot move money between your First Horizon accounts.

This guide walks you through setup (about 5 minutes), explains exactly what Truthifi allows and blocks with your First Horizon data, and shows you how to turn raw banking data into actionable First Horizon AI insights with ChatGPT.

What You Need

• First Horizon account with online banking access (Checking, Savings, Money Market, CDs, IRAs, Mortgage, or Wealth Management)

• ChatGPT Plus plan ($20/mo) with Apps & Connectors enabled

• Free Truthifi account registration at truthifi.com

• Approximately 5 minutes for setup

How to Connect ChatGPT to Your First Horizon Account

Ready to connect ChatGPT to your First Horizon accounts? Here's the exact flow.

1. Open Settings in ChatGPT — Go to chatgpt.com. Click your profile icon → Settings → Apps & Connectors.

2. Add the Truthifi connector — Scroll to Custom connectors → Add custom connector. Enter Name: Truthifi, URL: https://api.truthifi.com/mcp. Click Add.

3. Authorize your First Horizon accounts — ChatGPT redirects you to Truthifi's OAuth screen. Sign in to your Truthifi account, choose First Horizon from the institution picker, authenticate with your First Horizon username, password, and MFA code on First Horizon's domain (via BAA, Plaid, or Yodlee — whichever provider returns the cleanest mapping for your account types), select which First Horizon accounts to share with ChatGPT, confirm the read-only scope, and click Authorize.

4. Enable Truthifi per conversation — In any new chat: Tools → Use apps → toggle Truthifi on. This must be re-enabled each new conversation.

5. Verify the connection — Send: "What is my current First Horizon checking balance and last 10 transactions?" If ChatGPT responds with your actual First Horizon activity, the connection is live.

Perfect — you've now linked your First Horizon account to ChatGPT for comprehensive AI-driven financial planning.

Example Prompts for ChatGPT

• Southeast Cash Flow Audit — "Pull my First Horizon checking and money market activity for the last 6 months. Categorize spending into fixed (mortgage, utilities, insurance), variable (groceries, fuel, dining), and discretionary (travel, entertainment). Flag any month where my Memphis-area spending exceeded inflows and show me my savings rate per month."

• CD Ladder Optimization — "Review my First Horizon CD ladder. List each CD with its current rate, maturity date, and principal. Compare my weighted average rate to current First Horizon promotional CD rates and to top regional Southeast banks. Recommend a rung-by-rung renewal plan."

• Money Market vs. High-Yield Savings — "Compare the yield on my First Horizon money market account against my First Horizon savings APY and against a benchmark of top-yielding online savings accounts. Calculate the annual dollar difference at my current balance and recommend whether to shift funds."

• Mortgage Acceleration Analysis — "Using my First Horizon mortgage balance, rate, and remaining term, model three scenarios: paying minimums, adding $200/month extra principal, and one annual lump-sum payment from my tax refund. Show total interest saved and payoff date for each."

• IRA Contribution Tracking — "Show my First Horizon IRA year-to-date contributions and compare against the current IRS annual limit. Calculate the dollar amount and monthly auto-transfer I'd need to max out by December 31."

• Wealth Management Fee Review — "Pull every advisory fee, expense ratio, and account fee I've paid through my First Horizon wealth management account over the past 12 months. Show me the dollar total, the percentage of assets, and the 10-year compounding impact at 7% growth."

• Memphis Local Spending Categories — "Analyze my First Horizon checking transactions and tell me how much I spent at Memphis-area merchants (restaurants, retail, services) versus online or out-of-region merchants. Show the split as a percentage and trend over the last 12 months."

• Multi-Account Net Worth — "Aggregate every First Horizon account I've connected — checking, savings, money market, CDs, IRA, mortgage, wealth management — and produce a single net worth statement showing assets, liabilities, and the trend over the past 24 months."

• CD vs. Treasury Comparison — "Compare the yield on my First Horizon CDs to the equivalent-duration US Treasury rate today. Calculate the after-tax difference in my federal bracket and tell me which is more efficient for each maturity."

• Southeast Regional Banking Dashboard — "Build me an executive dashboard summarizing my First Horizon relationship: total deposits, total borrowings, YTD interest earned, YTD interest paid, wealth management performance, and average daily balance. Format as a single-page summary I could share with my CPA."

Why Truthifi?

5.1. Security

Your First Horizon username, password, and MFA code never touch Truthifi's servers. Authentication occurs directly on your provider's domain through BAA, Plaid, or Yodlee, creating a read-only, protocol-enforced connection secured with AES-256 encryption. ChatGPT receives only scoped data tokens, never your actual credentials. You maintain complete control and can revoke access anytime at First Horizon's connected apps settings or through your Truthifi dashboard.

5.2. Privacy

Your financial data stays under your complete control when using Truthifi. We never store login credentials from First Horizon or any financial institution. You decide which specific First Horizon accounts ChatGPT can access — you can share only checking, or only wealth management, or all account types. Data never gets sold to third parties, and connecting one AI tool doesn't automatically grant access to others.

5.3. Audit Trail

Every MCP data request is logged with complete session details for ChatGPT financial planning transparency. When ChatGPT accesses your First Horizon checking, CDs, IRA, or wealth management data, the timestamp and specific information retrieved gets recorded automatically. You maintain full visibility into which financial details were accessed during each interaction. This comprehensive tracking ensures you always know exactly what happened with your First Horizon information.

5.4. Data Quality

When First Horizon delivers raw transaction data through its data providers, Truthifi rebuilds historical information from BAA, Plaid, and Yodlee to correct inconsistencies. Our normalization process fills data gaps, deduplicates pending vs. posted transactions, and resolves merchant naming mismatches that could mislead ChatGPT financial planning algorithms. This approach ensures up to 10 years of clean, accurate transaction history — useful when your mortgage was originated by IBERIABANK before the 2020 merger and you need consolidated reporting.

About ChatGPT

Powered by advanced language processing, ChatGPT functions as a sophisticated financial analysis tool that connects to your accounts at First Horizon and other institutions through Truthifi. The Apps & Connectors feature must be enabled to access the full MCP ecosystem, which allows real-time integration with banking platforms, investment portfolios, and budgeting tools.

ChatGPT Plus ($20/mo) is the minimum tier that supports custom MCP connectors — Free accounts cannot reach First Horizon data. This deep protocol integration means fewer connection errors and more consistent data retrieval during extended analysis sessions. This connectivity transforms ChatGPT personal finance analysis from static advice into dynamic, account-specific recommendations based on your actual First Horizon transaction history, deposit balances, CD maturity schedule, and wealth management performance.

Frequently Asked Questions

Is it safe to connect my First Horizon account through Truthifi?

Connecting through First Horizon's authentication via BAA, Plaid, or Yodlee ensures your login credentials stay on First Horizon's own secure servers. When you connect, you're redirected to First Horizon's domain to log in directly with your username, password, and MFA code, then grant specific read-only permissions before returning to Truthifi. Your credentials never pass through our systems.

ChatGPT receives only a scoped data token with read-only access, meaning it cannot move money between your First Horizon accounts, make wire transfers, or change account settings. Every data request is logged for transparency, and you maintain full control through First Horizon's connected apps settings or our dashboard. Complete security details at https://truthifi.com/security.

Truthifi security overview →

What does Truthifi allow with my First Horizon data — and what does it block?

When you connect ChatGPT to First Horizon, the AI cannot move money between accounts, place wires, originate ACH, or change account settings due to architectural limitations. The read-only access token from BAA, Plaid, or Yodlee prevents ChatGPT from executing any transactions on your First Horizon account. Instead, ChatGPT can surface your spending categories, flag CD maturities, model mortgage payoff scenarios, and aggregate your wealth management performance.

Your First Horizon banker and wealth management advisor provide tailored guidance based on your full financial picture, while AI analysis supplements your understanding between professional meetings.

What about my First Horizon banker or wealth advisor?

The relationship between First Horizon advisors and ChatGPT creates a comprehensive support system. Your advisor knows Memphis-area markets, regional rate trends, and the nuances of your CD ladder and trust accounts. ChatGPT helps you arrive at advisor meetings already understanding your own numbers — your spending patterns, CD maturity schedule, fee load, and net worth trajectory.

What First Horizon account types does Truthifi support?

Truthifi supports connecting your First Horizon Checking, Savings, Money Market, CDs, IRAs, Mortgage, and Wealth Management accounts through its read-only MCP connector. Each account type is linked with the same security architecture — no transfers, no wires, no changes to your First Horizon settings. You can connect multiple account types simultaneously for a complete financial picture.

How does Truthifi compare to other options?

How do I disconnect ChatGPT from Truthifi?

To disconnect ChatGPT from Truthifi, go to Settings → Apps & Connectors → find Truthifi → Disconnect or Remove. You can also revoke access directly from First Horizon's online banking under connected apps. This won't affect your other AI connections, and ChatGPT will stop receiving your First Horizon data once disconnected.

Does the First Horizon connection work for accounts opened before the 2020 IBERIABANK merger?

Yes. If your account originated under IBERIABANK and migrated to First Horizon during the systems integration, Truthifi pulls the current First Horizon account record through BAA, Plaid, or Yodlee. Where pre-merger transaction history is fragmented, Truthifi's normalization layer reconciles the two histories so ChatGPT sees a continuous timeline rather than a gap at the merger date.

Do I need a paid ChatGPT plan?

Yes. To use ChatGPT with Truthifi and First Horizon, you need a Plus subscription at $20/mo or higher. Apps & Connectors with custom MCP servers is the feature that powers the integration, and it is not available on the Free tier.

Where is my data stored?

ChatGPT does not store First Horizon account data between conversations. When you connect through Truthifi's MCP, data flows directly into your active session. Once the conversation ends, nothing about your First Horizon balances or transactions remains in ChatGPT's memory for that thread.

How do I enable the ChatGPT connection with Truthifi each session?

In every new ChatGPT conversation, go to Tools → Use apps → toggle Truthifi on. The First Horizon account connection itself remains intact between sessions; only the per-conversation app toggle has to be re-enabled.

Does this replace my financial advisor?

No, connecting First Horizon through Truthifi does not replace your advisor. The platform offers data analysis, not advisory services, while ChatGPT supplements advisors between meetings with account-specific insights.

What is Truthifi?

Truthifi serves as an independent financial data platform that enables you to connect ChatGPT to financial accounts from over 18,000 US institutions, including First Horizon. The service operates on a subscription model and does not sell data, earn commissions, or sell financial products. Through secure MCP integration, ChatGPT can access your First Horizon accounts and other holdings for AI financial planning purposes.

Who can see my First Horizon data?

No external parties can access your First Horizon account information when using ChatGPT through Truthifi. Only ChatGPT receives your data during active conversations, and we maintain a subscription model that never involves selling your financial information.

Subject to ChatGPT privacy policy.

Can I connect both ChatGPT and Claude to my First Horizon account?

Yes. Each AI connection through Truthifi is independent. Connecting ChatGPT to First Horizon does not expose your data to Claude, and vice versa. You control which accounts each AI can see and can revoke either connection without affecting the other.

Can ChatGPT compare First Horizon to other Southeast and regional banks?

Yes. If you connect accounts from other regional banks, ChatGPT can compare deposit yields, fee structures, and CD rates. See chatgpt-frost-bank for Texas-based Frost Bank or chatgpt-comerica for Comerica.

How does ChatGPT compare to a robo-advisor for my First Horizon Wealth Management?

A robo-advisor makes investment decisions within a managed account. ChatGPT analyzes your existing First Horizon wealth management positions without moving or managing money — useful for fee reviews, allocation drift checks, and tax-loss harvesting candidate lists you can take to your First Horizon advisor.

Can ChatGPT help with tax planning on my First Horizon accounts?

ChatGPT can surface data relevant to tax planning — interest income from CDs and money market accounts, IRA contribution status, mortgage interest paid year-to-date — but it is not a tax advisor and cannot file returns. Take its output to a CPA for review.

What types of accounts can I connect beyond First Horizon?

Truthifi supports over 18,000 US financial institutions. You can connect AI to brokerage accounts, additional bank checking and savings, retirement accounts, HSAs, credit accounts, mortgage accounts, and more. Once connected, ChatGPT produces a unified AI financial dashboard across every account.

Is there a fee from Truthifi or First Horizon for using this?

First Horizon does not charge for read-only data access through BAA, Plaid, or Yodlee. Truthifi has its own subscription tiers — see truthifi.com/pricing. ChatGPT Plus is $20/mo and is required for MCP custom connectors.
