Chat Marks

Chat Marks is a browser extension that helps you organize the ChatGPT chat list more clearly. It adds visual organization tools to chats in the left sidebar, including marks, highlights, short labels, and filters, so it becomes easier to identify and manage conversations.

Each chat can have its own mark with a selected color and shape, making it easier to distinguish different types of conversations at a glance. Chat titles can also be highlighted with a marker-style effect, and short labels can be displayed for additional visual organization.

One of the main features is filtering. You can filter chats by mark color or shape to quickly narrow the list and find the conversations you need. This can be useful for separating chats by purpose, priority, or workflow.

Settings such as marks, colors, shapes, highlights, and labels are saved through Chrome Sync, so they can be carried across environments where you use the same Chrome account. For example, your setup can stay available across different devices. Filter state is not synced. Filters are treated as temporary, per-tab state and apply only to the tab you are currently using.

Chat Marks works by adding its own extension UI to the chat list on supported pages. It does not edit or modify ChatGPT’s underlying data, and it does not send your settings to a developer server.
