-## {% data variables.product.prodname_copilot %} features
+## Assistive features
+
+These tools are used synchronously, providing advice or suggestions as people work on a task.
 
 ### {% data variables.copilot.copilot_chat_short %}
 
-A chat interface that lets you ask coding-related questions. {% data variables.copilot.copilot_chat %} is available on the {% data variables.product.github %} website, in {% data variables.product.prodname_mobile %}, in supported IDEs _({% data variables.product.prodname_vscode %}, {% data variables.product.prodname_vs %}, JetBrains IDEs, Eclipse IDE, and Xcode)_, and in {% data variables.product.prodname_windows_terminal %}. Users can also use skills with {% data variables.copilot.copilot_chat_short %}. See [AUTOTITLE](/copilot/using-github-copilot/asking-github-copilot-questions-in-github) and [AUTOTITLE](/copilot/using-github-copilot/asking-github-copilot-questions-in-your-ide).

-### {% data variables.copilot.copilot_cloud_agent_tmp %}
+### Inline suggestions
 
-An autonomous AI agent that can research a repository, create an implementation plan, and make code changes on a branch. You can review the diff, iterate, and create a pull request when you're ready. You can also assign a {% data variables.product.github %} issue to {% data variables.product.prodname_copilot_short %} or ask it to open a pull request directly to complete a task. See [AUTOTITLE](/copilot/how-tos/use-copilot-agents/cloud-agent).
+Autocomplete-style suggestions from {% data variables.product.prodname_copilot_short %} in supported IDEs. See [AUTOTITLE](/copilot/using-github-copilot/getting-code-suggestions-in-your-ide-with-github-copilot).
 
-### Third-party coding agents ({% data variables.release-phases.public_preview %})
+If you use {% data variables.product.prodname_vscode_shortname %}, Xcode, or Eclipse, you can also use {% data variables.copilot.next_edit_suggestions %}, which will predict the location of the next edit you are likely to make and suggest a completion for it.
 
-You can use third-party coding agents alongside {% data variables.copilot.copilot_cloud_agent %}. See [AUTOTITLE](/free-pro-team@latest/copilot/concepts/agents/about-third-party-agents).
+### {% data variables.copilot.copilot_for_prs %}
+
+AI-generated summaries of the changes that were made in a pull request, which files they impact, and what a reviewer should focus on when they conduct their review. See [AUTOTITLE](/copilot/using-github-copilot/creating-a-pull-request-summary-with-github-copilot).
+
+### {% data variables.copilot.copilot_desktop_short %}
+
+Automatically generate commit messages and descriptions with {% data variables.copilot.copilot_desktop_short %} based on the changes you make to your project.
+
+## Agentic features
+
+These features can work autonomously without direct human supervision. However, they typically need human approval to perform sensitive actions, such as running commands in a developer's terminal or merging a pull request.
 
 ### {% data variables.copilot.copilot_cli_short %}
 
-A command line interface that lets you use {% data variables.product.prodname_copilot_short %} from within the terminal. You can get answers to questions, or you can ask {% data variables.product.prodname_copilot_short %} to make changes to your local files. You can also use {% data variables.copilot.copilot_cli_short %} to interact with {% data variables.product.prodname_dotcom_the_website %}—for example, listing your open pull requests, or asking {% data variables.product.prodname_copilot_short %} to create an issue. See [AUTOTITLE](/copilot/concepts/agents/about-copilot-cli).
+A command line interface that lets you use {% data variables.product.prodname_copilot_short %} in your terminal. Use the CLI to add features or fix bugs, then create a pull request. Start {% data variables.product.prodname_copilot_short %} working on a task in your terminal, then continue working in the same session on {% data variables.product.prodname_dotcom_the_website %}, or on your mobile. See [AUTOTITLE](/copilot/concepts/agents/about-copilot-cli).

+### {% data variables.copilot.copilot_cloud_agent_tmp %}
+
+An autonomous AI agent that can research a repository, create an implementation plan, and make code changes on a branch. You can review the diff, iterate, and create a pull request when you're ready. You can also assign a {% data variables.product.github %} issue to {% data variables.product.prodname_copilot_short %} or ask it to open a pull request directly to complete a task. See [AUTOTITLE](/copilot/how-tos/use-copilot-agents/cloud-agent).
+
+### Third-party coding agents ({% data variables.release-phases.public_preview %})
+
+You can use third-party coding agents alongside {% data variables.copilot.copilot_cloud_agent %}. Third-party agents are subject to the same security protections, mitigations, and limitations as {% data variables.copilot.copilot_cloud_agent %}. See [AUTOTITLE](/copilot/concepts/agents/about-third-party-agents).
 
 ### {% data variables.copilot.copilot_code-review_short %}
 
 AI-generated code review suggestions to help you write better code. See [AUTOTITLE](/copilot/using-github-copilot/code-review/using-copilot-code-review).
 
 Several {% data variables.copilot.copilot_code-review-tools_short %} are in {% data variables.release-phases.public_preview %} and subject to change. See [AUTOTITLE](/copilot/concepts/agents/code-review).
 
-### {% data variables.copilot.copilot_for_prs %}
+### Agent mode in IDEs
 
-AI-generated summaries of the changes that were made in a pull request, which files they impact, and what a reviewer should focus on when they conduct their review. See [AUTOTITLE](/copilot/using-github-copilot/creating-a-pull-request-summary-with-github-copilot).
+Allow {% data variables.product.prodname_copilot_short %} to work autonomously in the IDE. {% data variables.product.prodname_copilot_short %} will determine which files to make changes to, offer code changes and terminal commands for the user's approval, and iterate to remediate issues until the original task is complete.
