# Track changes

## Introduction

Track Changes is a [premium feature](/getting-started/free-and-premium-plans/premium-features.md). Overleaf premium features are available to participants in [Overleaf Commons](https://www.overleaf.com/for/universities), members of [group subscriptions](https://www.overleaf.com/for/groups), and owners of individual [subscriptions](https://www.overleaf.com/user/subscription/plans). All collaborators invited to a project owned by an Overleaf account with this premium feature will be able to use Track Changes in that project. The Track Changes feature is not available through the discontinued Personal plan.

This article shows how to use Track Changes. You can use Track Changes to observe changes made by some, or all, co-authors or those you have invited to review, or proofread, your work. At a glance you’ll see any revisions which you can also comment upon to suggest further changes, ask for clarifications, request sources and much else besides.

You can leverage Track Changes and/or comments as a way to remind yourself of any follow-up work required based on your co-authors’ edits and contributions. Comments can be replied to, resolved (archived) and permanently deleted—see the article [Commenting](/collaborating/commenting.md) for some video clips showing how to use Overleaf’s commenting features.

## Accessing Track Changes

Track Changes can be accessed by switching to reviewing mode. To switch modes, click the icon at the top right of the Overleaf editor toolbar and choose from the options that appear.

* If you have edit access, you can switch between Editing and Reviewing.
* If you only have review or view access, you won't be able to change your mode.

### Configuring whose changes will be tracked

To force another collaborator’s changes to be tracked, the project owner can update their [sharing permissions](/collaborating/reviewing-and-reviewers.md).

## How to accept or reject all tracked changes

Follow these steps to accept (or reject) all tracked changes contained in a part, or whole, of your document.

1. Select the section of text containing the set of tracked changes you want to accept or reject. To accept or reject *all* tracked changes, select the entire document text using `ctrl+A` (Windows) or `cmd+A` (Mac).
2. After the text is selected, the option to **Accept selected changes** or **Reject selected changes** will appear, as shown in the following example:

3. Select **Accept selected changes** or **Reject selected changes** to display a pop-up window asking you to confirm or cancel your choice.

{% hint style="warning" %}
If you make a copy of your project, all tracked changes are automatically applied in the copied version. They will no longer be shown as tracked.
{% endhint %}

## Notifications

{% hint style="info" %}
Notifications on project activity must be enabled in your [Account Settings](https://www.overleaf.com/user/notification-preferences).
{% endhint %}

You can manage notification emails per project through the Project Settings (File > Settings > Project Notifications) for the following types of activity:

* **All project activity** - You’ll be notified about *all* tracked changes (and [comments](/collaborating/commenting.md)).
* **Replies to your activity only** - You’ll be notified about activity on *your* tracked changes (and comment replies).

{% hint style="warning" icon="timer" %}
Notifications are not real-time, instead they are bundled in ten minute increments to avoid inbox overload.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.overleaf.com/collaborating/track-changes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
