Features & Capabilities

Timestamp Injector for ChatGPT

A browser extension that automatically injects customizable timestamps into ChatGPT conversations. It displays the exact time each message was sent or received, directly below the message bubble.

Features

Automatic Injection: Timestamps are automatically added to all messages (user and AI) in a ChatGPT conversation.
Customizable: Click the extension icon to customize the appearance of the timestamps:
Color: Choose any color for the timestamp text.
Font Size: Select between Small, Medium, and Large.
Format: Choose how the date and time are displayed (e.g., full date and time, short date, or just time).
Seamless Integration: Matches the native look and feel of ChatGPT.
Cross-Browser Support: Works on Chrome, Edge, and Firefox.

Note for Firefox users: Due to a long-standing Firefox extension bug regarding native color pickers in popups, the custom color picker is disabled on Firefox. Only the preset colors are available.

Is Timestamp Injector for ChatGPT Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Timestamp Injector for ChatGPT requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Timestamp Injector for ChatGPT is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
