Grouping, Filtering, and Time Range

Explorer lets you answer any cost question: by team, by service, by provider, across any time range. Five settings shape your query: grouping, filters, time range, granularity, and cost type. The fastest way to set them is to describe what you want in plain English. Type "Show our OpenAI spend by team for the last 3 months" and Explorer configures everything in one step. You can also adjust each control individually using the sections below.

Build your query with AI using Filter Assist (preview)

Filter Assist uses AI to configure your Explorer query from a plain English question. No need to know which settings to change.

1. Click the sparkle icon (✨) next to the expression builder.

2. Enter your question in plain English, or click one of the suggested queries. Filter Assist applies the right grouping, filters, time range, granularity, and cost type based on your question.

3. Explorer updates instantly. Every setting Filter Assist applies is visible in the standard controls. Nothing is hidden.

4. Fine-tune if needed. All applied settings are fully editable using the controls described in the following sections.

Example queries:

• "What was our total cloud spend over the last 3 months?"
• "Show our cost breakdown by cloud provider"
• "Show hourly cloud spend for the past 3 days"
• "What was the OpenAI spend for each AI Agent in November 2025?"
• "What Engineering Team spent the most money over the last 4 weeks?"
• "How is our weekly spend trending over the past 6 months?"

Tips for better results:

• Include time ranges in your query: "last 30 days," "past 3 months," "last week"
• Name Dimensions specifically: cloud provider, service, team, account
• Keep queries direct; one question per query works best

Group By

Group By organizes your costs by any category (Dimension) your business cares about.

To change the grouping, click the Group By selector at the top of Explorer and choose a Dimension. The graph and table update instantly. The total stays the same; only the breakdown changes.

Available categories:

Group by two dimensions

Sometimes a single Dimension doesn't answer the full question. "How much does each team spend?" is useful, but "how much does each team spend on each service?" is actionable. Adding a second Dimension nests one category inside another, so you can see how they interact.

To add a second Dimension, select Add Group By and select it.

For more on how Dimensions work, see Dimensions.

Filters

Filters narrow Explorer to a specific subset of your costs. For example, you can filter to one team, one service, one region, or any combination.

Click a row in the cost table to filter to that item and drill deeper. Keep clicking to reach individual resources.

Use the filter expression builder for more control:

1. Select Add Filter + at the top of Explorer.
2. Select a Dimension to filter on.

3. Choose an operator and select values.

   Operator	What it does
   is	Shows only the values you select (default)
   is not	Hides the values you select
   contains	Shows values that include your search term (case-sensitive)
   does not contain	Hides values that include your search term (case-sensitive)

4. Continue to add more filters to refine your spend by repeating steps 1-3.

Time Range

Time Range sets which period of spend you are analyzing.

To change it, click the Time Range selector and choose a predefined range or set custom dates.

Granularity

Granularity controls how costs are grouped on the time axis (each bar or point on the graph represents one hour, one day, one week, or one month).

Partial periods

When your time range does not align to week or month boundaries, Explorer shows partial periods at the edges.

Weeks always start on Monday and end on Sunday. For example, if you select all of January 2025 with weekly granularity, the first bar covers January 1 (Wednesday) through January 5 (Sunday) and the last bar covers January 27 (Monday) through January 31 (Friday). The three weeks in between are full Monday-to-Sunday weeks.

Months follow the same pattern. If you select November 15, 2024 through February 15, 2025 with monthly granularity, November and February are partial months, while December and January are full months.

When weekly or monthly granularity is selected, Explorer extends your date range slightly to include complete periods. This can cause the total cost displayed to differ from the exact dates you selected.

Visualization

Visualization controls change how the cost graph displays your data.

• Series: how many groups appear in the graph. Default is top 10 by cost; the rest combine into Remaining.
• Chart type: bar, line, or stacked line.

Graph interactions

Click a bar on the graph to add a filter for that element. This changes your query and updates both the graph and table.

The following controls adjust the graph visually without changing your query or the cost table:

• Click a legend item to show only that group on the graph
• Shift + click a legend item to remove that group from the graph
• Click and drag on the graph to zoom into a specific portion of the displayed time range
• Select Reset ( ↺ ) to revert the graph to its original state

Query History and Favorites

Explorer saves every query you run, so you can return to any previous query without rebuilding it.

Click the Query History icon to open the panel:

• Recent: your queries in reverse chronological order. Click any entry to reload it.
• Favorites: up to 12 saved queries. Click the heart icon on a recent query to save it.
