Anthropic says conversations in Claude’s new Personal Finance hub “aren’t used to train our models.” OpenAI’s page for the ChatGPT finance tool it launched in May sets a different rule: those conversations “follow the same model training settings you choose across ChatGPT.” Claude’s version runs on paid plans, with Pro listed at $17 a month on annual billing.
Claude’s launch post on X had 2,859,843 views when we checked at 23:30 UTC on 5 November, about 2.86 million. The launch came 174 days after OpenAI’s 15 May preview, by our arithmetic.
Business Pill · The Model and the Harness
A short Business Engineer explainer on the difference between an AI model and the harness around it. It teaches the general idea only and says nothing about Anthropic, OpenAI or these tools.
The key insight: Claude and ChatGPT read bank accounts through the same Plaid connection, but their published terms differ on training: Anthropic says Personal Finance hub chats aren’t used to train its models, while OpenAI’s page applies each user’s ChatGPT training setting; Claude arrived 174 days after ChatGPT’s preview, by our arithmetic.
Both tools connect to banks through Plaid. Anthropic’s announcement says accounts are linked once users sign in to their bank “yourself through Plaid, a service that connects apps to banks.” OpenAI’s page says ChatGPT guides users “through securely linking accounts through Plaid, with Intuit support coming soon.”
OpenAI’s page says ChatGPT launched “with support for more than 12,000 financial institutions.” TechCrunch reported in May that the list included “Schwab, Fidelity, Chase, Robinhood, American Express, and Capital One.”
Introducing Personal Finance in Claude, in beta in the US.
Connect the accounts you choose, and Claude answers your money questions in everyday language, from your own balances and transactions. Access is read-only, and Claude can’t move, manage, or invest your money.
Claude’s official account announced Personal Finance on X at 18:00 UTC on 5 November, describing a US beta that connects the accounts users choose with read-only access. The post had 2,859,843 views when we checked at 23:30 UTC; this piece compares the terms in Anthropic’s announcement with OpenAI’s for ChatGPT.
What Each Tool Can See
For the accounts a user connects, Anthropic says Claude sees “the bank’s name, each account’s name, type, and last four digits, balances and credit limits, and up to two years of transactions.” That is up to 24 months of history, by our arithmetic.
OpenAI’s page says ChatGPT “can access your balances, transactions, investments, and liabilities” and that it “cannot see full account numbers or make any changes to your accounts.” Anthropic’s post says Claude’s access is read-only and that Personal Finance “can’t move, manage, or invest your money.”
Training and Deletion
Anthropic’s rule depends on where the chat happens. Inside the Personal Finance hub, it says, conversations “aren’t used to train our models.” For anything shared with Claude outside the hub, the post says users’ existing privacy settings apply.
OpenAI’s page ties finance chats to the general ChatGPT training setting, which it says users can change at any time in their data controls. It says that once accounts are disconnected, “your synced account data will be deleted from OpenAI’s systems within 30 days.” Anthropic’s post says: “You can unlink an account anytime, and then Claude can no longer see its data.”
Who Gets Each, and When
Anthropic says Personal Finance “starts rolling out in beta this week, on the Pro, Max, and Ultra plans in the US.” Claude’s pricing page lists Pro at $17 a month with the annual discount ($200 billed up front) or $20 billed monthly, Max at $100 and Ultra at $200 a month.
OpenAI started with a preview for Pro users in the US on 15 May. An update on its page dated 25 June says the experience “is now available to Plus and Pro users in the U.S. on web, iOS, and Android.” Claude’s launch came 133 days after that wider ChatGPT rollout, by our arithmetic.
How Banks Are Responding
Investing.com, reporting the launch, wrote that “Charles Schwab Corp. (NYSE:SCHW) said it blocks personal agents that can complete financial tasks independently.” It added that Schwab “has developed its own AI assistant”. Bloomberg ran the news under the headline “Anthropic, Plaid Collaborate on AI Consumer Finance Guidance”; we have not read that article’s body.
Anthropic’s own post points the other way. It says it would like to hear from “banks, wealth managers, and financial services companies who want to help shape it.”
As we read the two pages, the products share their plumbing and differ in their data terms: the bank connection is Plaid in both cases, while the training rule for finance chats is set differently.
As we read Anthropic’s post, the training carve-out covers the Personal Finance hub only; outside it, users’ existing privacy settings apply.

“When you chat with Claude in the Personal Finance hub, those conversations aren’t used to train our models.”
Three Implications
FOR USERSOpenAI’s page says synced account data is deleted within 30 days of disconnecting; Anthropic’s post says Claude can no longer see an unlinked account’s data.
FOR BANKS Investing.com reports that Schwab blocks personal agents that complete financial tasks on their own, while Anthropic’s post invites banks to help shape the product.
FOR ANTHROPIC Claude’s launch post had 2,859,843 views when we checked at 23:30 UTC.
The framework says: “In the embedding era, value comes from what the software connects to.”
As we read it, both assistants now connect to the same bank data through Plaid, so the terms on what happens to that data are where the two products differ.
What Is Not Established
Anthropic’s announcement does not say how long it keeps an unlinked account’s data. OpenAI’s page does not say what the default training setting is for a new user. Neither company gives user numbers for its finance tool, and neither says what it pays Plaid.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Claude and ChatGPT now read bank accounts through the same Plaid connection, but their published terms differ on training: Anthropic says finance-hub chats are not used to train its models, while OpenAI’s page applies each user’s ChatGPT training setting. Claude arrived 174 days after ChatGPT’s preview, by our arithmetic.
A note on sourcing. Anthropic’s terms are from its announcement of 5 November 2026; OpenAI’s terms are from its own page of 15 May 2026 and its 25 June update; plan prices are from Claude’s pricing page; Schwab’s stance is Investing.com’s report. The view count is our reading of Claude’s post at 23:30 UTC; the 174-day and 133-day gaps are our arithmetic.
