# Usage & Limits
> See what your workspace spends its balance on, and the ceilings your plan applies
Two pages answer two different questions. **Settings → Usage** shows what you have spent and on what. **Settings → Limits** shows how much of each resource your plan allows.
## Usage
Open **Settings → Usage**. The date range picker in the header drives every chart on the page: last 7, 30, 60 or 90 days, year to date, or a custom range.
The overview card gives you the headline numbers for the selected range:
* **Total Spend**, in dollars.
* **Total Credits**, the internal unit every billable operation draws from. You pay in dollars; credits just let messages, knowledge searches and broadcast sends draw from one balance.
* A **daily chart** of both, so a spike is easy to spot. Use the controls in the corner to switch between bar, line and area, and to export the underlying numbers as CSV.
### Where the money went
**Usage by Event Type** breaks the same range down by what produced the spend, with each type's share of the total.
| Event type | What it covers |
| :------------------------------------------------ | :-------------------------------------------------------------------- |
| **AI Tokens** | Assistant replies and everything else the model generates |
| **Speech-to-Text** / **Text-to-Speech** | Voice notes transcribed, and spoken replies |
| **Embeddings** | Indexing and searching your knowledge base |
| **Conversation Analysis**, **Follow-up Analysis** | Automatic analysis of conversations and follow-up decisions |
| **Memory Reconcile**, **Memory Summarize** | Keeping contact memory up to date |
| **Broadcast Email / SMS / WhatsApp** | Per-message fees for broadcasts, split by marketing and transactional |
| **Workflow Run** | Workflow executions |
**Spend by Event Type Over Time** stacks the same categories per day, which is what you want when a total moved and you need to know which category moved with it.
Spot a category you did not expect? Compare two ranges before changing anything. A single busy day can dominate a 7-day view and disappear in a 30-day one.
## Limits
Open **Settings → Limits** for the ceilings that come with your current plan.
The table covers how many members, assistants, channels, actions, active contacts, segments, broadcasts, workflows, sub-organizations and custom domains your workspace can have, plus the size of your knowledge base.
Some rows are not capped at all. Conversations, broadcast sends, integrations and API access are **unlimited** on every plan: you are billed for what you use rather than blocked at a ceiling. The last rows show the per-message fee for each broadcast channel, which is the usage side of the same page.
Limits follow your plan, so upgrading raises them immediately. If your workspace needs more than the listed ceilings, the banner at the top of the page points to Enterprise, where limits are set per workspace.
Every sub-organization gets its own limits, so a busy client workspace never consumes another one's headroom.
## Keeping spend predictable
Usage and limits are only half the picture. The controls that actually cap what you can spend live in billing:
* A **monthly spending limit** pauses billable operations once the cap is reached.
* **Auto-recharge** tops the balance up when it dips below a threshold, so sends do not stall.
Both are covered in [Pricing and Plans](/guides/pricing-and-plans#billing-management).
