# BI Similarity

The BI Similarity tool within Datalogz' Control Tower is designed to automatically detect and quantify duplication among your BI reports, dashboards, and underlying datasets across various platforms like Power BI, Tableau, and Qlik.

#### Availability

* **Power BI** — Generally Available. BI Similarity for Power BI datasets and reports is fully supported for all customers.
* **Tableau** — Private Preview. BI Similarity for Tableau dashboards and workbooks is available to a limited set of customers. [Contact your Datalogz representative](mailto:support@datalogz.io) to request access.

With BI Similarity, you can use the Cluster Map to:

* [Browse](/guides/bi-similarity/bi-similarity-cluster-map.md) through similar reports and datasets.
* [Explore](/guides/bi-similarity/compare-similar-assets.md) what makes the assets similar. Open any pair to see a side-by-side **Comparison view** with the similarity score, the signals driving it (e.g., overlapping data source), and a metadata diff that highlights which fields are the same and which differ
* Act on the recommendation surfaced in the Comparison view, for example, **Possible Redundancy Detected** when two assets are highly similar, using the inline actions to **Keep Both** or **Notify Owners**

You can also find similar assets in the [Inventory](/guides/inventory.md).
