# AI impact

The [AI tools → AI impact](https://app.swarmia.com/ai/impact/code) page helps you understand how pull requests assisted by different AI coding tools — or no AI tools — perform across metrics like throughput, cycle time, batch size, and review time.

This makes it easier to [answer questions like](https://www.swarmia.com/blog/staged-approach-AI-adoption-for-engineering/): Is AI-assisted work moving through your system faster or slower? Which teams benefit most from AI tools? How are quality indicators responding to increased AI usage?

## Available metrics

* PRs merged (throughput)
* Cycle time
* Time to first review
* Time in review
* Batch size

## Available selections

### Comparison type

First, use the tabs to select how the pull requests are grouped:

* **AI tools:** GitHub Copilot vs Claude Code vs Cursor vs everything else. 
* **Modes:** [local changes (editor/CLI)](/features/ai-tools/ai-tool-detection-and-filters.md#local-changes-editor-cli) vs [cloud agent](/features/ai-tools/ai-tool-detection-and-filters.md#cloud-agent) vs [review agent](/features/ai-tools/ai-tool-detection-and-filters.md#review-agent) vs everything else. 
* **AI used:** AI-assisted PRs (based on the tools and modes you select) vs everything else.

The structure of the page is the same for all comparisons.

### Included modes

Select which modes ([local changes (editor/CLI)](/features/ai-tools/ai-tool-detection-and-filters.md#local-changes-editor-cli), [cloud agent](/features/ai-tools/ai-tool-detection-and-filters.md#cloud-agent), and [review agent](/features/ai-tools/ai-tool-detection-and-filters.md#review-agent)) are included in the comparison.

There's also an option to [include only high-confidence matches](/features/ai-tools/ai-tool-detection-and-filters.md#local-changes-high-confidence-only) in the *local changes* mode.

## Frequently asked questions

### Why is the total under "PRs merged" lower than the sum of its parts?

A single pull request can be associated with multiple AI tools and modes. For example, a developer might use both Cursor and Claude Code on the same PR. In that case, the PR is counted once in the Cursor category and once in the Claude Code category.

### How do you determine which AI tools to show for a PR?
