# Compare Mode

> How to compare ranges side by side and identify differences.

<Note>
  Compare mode is available on **Pro** and **Elite** plans.
</Note>

## What is compare mode?

Compare mode lets you view two or more ranges side by side in the Study workspace. It's useful for:

* Comparing your range against a solver solution
* Seeing how a range changes between positions
* Comparing opening ranges across different stack depths
* Reviewing differences between GTO and simplified ranges

## Enter compare mode

<Steps>
  <Step title="Open the Study workspace">
    Navigate to **Study** and select a spot.
  </Step>

  <Step title="Click Compare in the toolbar">
    In the toolbar above the grid, click the **Compare** button.
  </Step>

  <Step title="Add ranges to compare">
    The workspace splits to show multiple grids. Click **Add** on the empty panel to select another spot or strategy to compare against.
  </Step>
</Steps>

You can compare up to **4 ranges** simultaneously.

## Diff overlay

When comparing ranges, you can enable the **Diff overlay** to highlight cell-by-cell differences between two ranges:

| Color     | Meaning                                              |
| --------- | ---------------------------------------------------- |
| **Green** | Cells that match (same action in both ranges)        |
| **Red**   | Cells that differ (different actions between ranges) |
| **Gray**  | Cells that are empty in both ranges                  |

The diff overlay makes it immediately obvious where two ranges disagree.

## Diff info panel

When the diff overlay is active, a **Diff Info panel** shows summary statistics:

* Total cells that match
* Total cells that differ
* Percentage agreement
* Which hand classes have the most differences

## Synced navigation

In compare mode, you can enable **synced navigation**. When enabled, selecting a new spot in one panel automatically loads the equivalent spot in the other panels. This lets you quickly step through all positions and compare the same decision across strategies.

## Exit compare mode

Click the **Compare** button in the toolbar again to return to the single-grid view.

## Practical uses

<Tip>
  **Compare your ranges against the Library.** Add a GTO solution from the Library, then compare it against your custom range for the same spot. The diff overlay shows exactly where you deviate from GTO, which can help you decide if those deviations are intentional or accidental.

* **Before and after import** — Compare your hand-built range against the solver output before replacing it
* **Stack depth comparison** — See how your opening range should change between 100bb and 25bb
* **Coach review** — Compare your ranges against a coach's recommended ranges
