Who it is for
Club and amateur racing drivers who already log sessions in ApexLog and want to question that history in plain language.
ApexLog
Read-only access to a personal track day logbook
Overview
What ApexLog does
ApexLog records what happened at a track day, and this connector lets a driver interrogate that record conversationally. Questions can be about lap comparisons broken down by sector, the point in a lap where time went missing, the setup and tyre condition used at a given event, or how much life is left on a set of pads.
The logbook keeps the surrounding detail too: the car, tyre model and age, session setup, component wear, weather, track. GPS traces are available, and OBD channels such as fuel and temperatures appear where they were recorded.
The connection is read-only and limited to the account holder's own data. It cannot edit or delete entries. There is no cap on questions, since it runs on the driver's existing ChatGPT plan.
What stands out
The connector has no write access at all, so nothing in the logbook can be altered through conversation.

Where ApexLog is listed
ApexLog is listed in the ChatGPT apps directory only. Marcin Sitko 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.
