WhichPost

Claude · ChatGPT

Use WhichPost in Claude and ChatGPT

Ask which creators to rebook, test again or pause, right in the chat. Answers come from your own WhichPost reports, with a likely range on every number and a link to the full report.

Your connector address

Paste this into Claude or ChatGPT. It's the same address for both.

What you can ask

Questions that end in a decision

Ask in your own words. Every answer about your campaign carries the same ranges and calls as your report.

  • “Which creators should I rebook this month?”

    Each creator's call (rebook, test again or pause) with paying customers and cost per paying customer, each as a likely range.

  • “What did @creator bring in paying customers?”

    That creator's paying customers and cost with their ranges, and the plain reasons behind the call.

  • “Compare my two biggest creators on cost per paying customer.”

    Side by side. One is called cheaper only when its range sits clearly below the other's.

  • “Is my campaign data complete?”

    Whether your revenue source and posts are up to date, and which posts' views aren't read yet.

  • “What would make my report more certain?”

    What more data would narrow the ranges: creators to test again, trials still running, posts to add.

  • “Mark our Product Hunt launch on 12 October.”

    Adds the launch, so sales around it aren't credited to creators. Only if you allowed it when connecting, and the assistant checks with you first.

  • “What does WhichPost cost, and is it a fit for our app?”

    Plans and prices, plus a quick fit check from a few questions about your campaigns.

Privacy

What the assistant can and can't see

You choose one workspace when you sign in. The assistant sees nothing else.

It can

  • Read that workspace's reports, each creator's call with its ranges, marked events and whether your data is up to date.
  • Create a fresh report when you ask it to.
  • Mark a launch, press mention or other event, only if you ticked that box when connecting, and only when you ask.

It can never

  • See your Stripe or RevenueCat keys, or your customers' details.
  • Delete anything, or change your reports, payouts or account.
  • See your other workspaces.

Disconnect any time

Go to your account, find Connected assistants and select Disconnect. Access ends at once. Connections also end on their own after 90 days; connect again to keep going.

Your assistant may phrase answers its own way. The numbers and calls come from your report, and the report link is always the record.
