Understanding Blocks
How Starlight's usage-based block system works.
Starlight uses a block-based system. Every AI-powered action costs a set number of blocks, and your plan determines how many blocks you get each month.
Block Costs
| Action | Blocks | Description |
|---|---|---|
| Search | 12 | Run a new lead or company search |
| Load more results | 8 | Fetch the next page of search results |
| AI search enhance | 2 | AI-powered query refinement |
| Draft with AI | 4 | AI-draft personalized outreach for a lead |
| Preview with AI | 4 | Preview a draft for a recipient in the Outbound builder |
| Enhance brief | 2 | AI-polish your campaign brief |

| Agent tool call | 1 | Each action the AI chat agent runs, added to that action's own cost |
Chatting with the AI agent is free — ask questions and plan as much as you like. You're only charged when the agent takes an action: each tool call costs 1 block plus that action's own cost (for example, a lead search the agent runs is 12 + 1).
Checking Your Balance
Your current block usage is always visible in the sidebar at the bottom left. It shows a progress bar with blocks used out of your total allowance.
For a per-charge history of every block spent, open Settings → Blocks. It shows a running balance, your recent usage trend, and each transaction with the action that caused it. Plan-level usage lives in Settings → Plans & Billing.
Monthly Reset
Blocks reset every 30 days from when your billing cycle started. Unused blocks do not roll over to the next month.
Running Low on Blocks
When your blocks are running low, you'll receive a Blocks Low notification. You can:
- Upgrade your plan for more monthly blocks — see Plans & Pricing
- Wait for reset — blocks refresh at the start of your next billing cycle
What Happens When Blocks Run Out
When you're out of blocks:
- AI-powered actions (search, drafting, meeting notes) will show an upgrade prompt
- Already-scheduled messages will remain queued and send when blocks are available
- Manual actions (viewing contacts, reading inbox) continue to work normally
