Who it is for
Self-published authors who sell through more than one platform and already track royalties in Book Report.
Overview
Book Report collects an author's sales figures from Kindle Direct Publishing, Draft2Digital, and other publishing platforms, then organises them in one place. This app hands that organised data to ChatGPT for questions and follow-ups.
The kinds of analysis described include summarising trends over time, setting one period against another, finding the strongest performing titles and series, and splitting earnings by distributor or by marketplace. Follow-up questions build on the same retrieved data.
Access runs one way. The app can pull reports and catalogue context but cannot change anything in Book Report, in the account, or in the connected publishing platforms.

The connection is read-only, so no sales or account records can be altered through it.
Availability
Book Report is listed in the ChatGPT apps directory only. Chapter 14 Publishing Inc has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Book Report's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Chapter 14 Publishing Inc, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
