Your numbers, in any ChatGPT thread.
Pull a financial fact into whatever you're already writing. Drop last year's net income into a board update, AR aging into a status email, or your cash position before a call. Same governed connection, surfaced where you think.
A number in the thread you're already in.
ChatGPT is the cross-service surface. You're mid-task, drafting or thinking, and you want a Prosper fact without leaving. It's not your primary bookkeeping interface, the real work lives in Prosper or Claude.
Board updates
"Drop last year's net income into this board email." The number lands in the thread you're already drafting, cited to the workspace and period.
Status emails
"What's my AR aging?" Pull it straight into the update you're writing for an investor or partner, no tab-switching, no copy-paste from a report.
Pre-call prep
"What's my cash position right now?" Get the figure before a call without opening the books, then keep working in the same thread.
Quick lookups
Net income, biggest expense category, uncategorized backlog, a duplicate-charge check. Fast facts and synthesis, surfaced where you're already thinking.
What ChatGPT will never do
The GPT reads your books and can draft, but never executes the irreversible. Anything that moves money, closes the books, or destroys a record stays inside Prosper, behind a person.
- Post journal entries
- Send, void, or write off invoices
- Close the period
- Approve reconciliations
- Issue refunds
- Delete anything
Every call is workspace-scoped, OAuth-authorized, and audit-logged. Each number cites the workspace and period it came from.
Use the published GPT, or build your own.
The Prosper GPT is already published, so you don't have to build anything. Open it, sign in once with OAuth, pick your workspace, and ask.
The published Prosper GPT
Open the GPT, send any message, and ChatGPT prompts you to sign in with prosperfinance.app. Approve the scopes, pick a workspace, and you're authorized. Read calls can be set to Always Allow; writes always confirm individually.
Build your own
Prefer a private deployment? In ChatGPT, create a GPT and import the Action from the Prosper OpenAPI schema, then set the privacy policy URL.

ChatGPT is the lookup surface. To approve decisions, work the review queue, and assemble a CPA packet in conversation, use the Claude integration. Same governed connection, more reach.
Put your numbers where you already work.
Prosper design partners get hands-on setup and shape where the connection goes next. Nothing destructive can happen from the outside.
