# BI Similarity

BI Similarity automatically detects and quantifies duplication across your BI estate: the multiple versions of the same report or dataset that different teams built and never reconciled. It finds duplicate and near-duplicate assets in Power BI and Tableau, scores how similar they are, and gives you the tools to act.

#### Availability

* **Power BI**:  Generally Available. BI Similarity for Power BI datasets and reports is fully supported for all customers.
* **Tableau**: Preview. BI Similarity for Tableau dashboards and data sources 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).

## 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.datalogz.io/guides/bi-similarity.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.
