Overview

## What Timebook does

Timebook records billable work for independent professionals and small teams, with clients and projects organized inside it. From ChatGPT, the connector lists clients and projects, starts and stops a timer, logs work done in the past, and shows recent entries.

Existing entries can be changed or removed, but only within whatever the connected assistant has been permitted to modify. That boundary is stated in the record without further detail. Squidcode LLC publishes it. Nothing in the entry covers invoicing, hourly rates, exports, or reporting, so the described scope stays on capturing and correcting time rather than what happens to it afterwards.

### Who it is for

Solo practitioners and small teams that bill hourly and log time as work happens.

### What stands out

Editing and deleting entries is bounded by explicit permission rather than open by default.

## Where Timebook is listed

Timebook is listed in the ChatGPT apps directory only. Squidcode LLC 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.
