How the Wallet System Works: Pay-Per-Use AI
No subscriptions. No minimums. Just add funds, use AI, and pay for what you consume. Here's everything you need to know about the wallet system.
How It Works
The Basics
1. **Add funds** to your wallet
2. **Select assistants** you want to use
3. **Use via embed or API**
4. **Costs deduct** automatically per conversation
5. **Top up** when balance gets low
It's like a prepaid phone plan for AI.
Why Prepaid?
**Predictable costs**
You control exactly how much you spend. No surprise bills.
**No commitment**
Start with $10. Scale to $10,000. No contracts.
**Immediate access**
Funds available instantly. No approval process.
**Usage flexibility**
Use across multiple assistants. Allocate as needed.

Understanding Costs
Token-Based Pricing
AI usage is measured in **tokens**:
- Tokens are fragments of words (~4 characters)
- Both input (your message) and output (AI response) use tokens
- A typical conversation: 500-2,000 tokens
Per-Assistant Pricing
Each assistant has a per-million-token price:
- Set by the assistant creator
- Minimum: $3.75 per million tokens
- Typical range: $3.75-$15 per million tokens
Cost Calculation
```
Cost = (Tokens Used / 1,000,000) × Token Price
```
**Example:**
- Conversation uses 1,500 tokens
- Assistant price: $7.50 per million tokens
- Cost: (1,500 / 1,000,000) × $7.50 = $0.01
Yes, most conversations cost pennies.
Typical Costs
| Use Case | Avg Tokens | Typical Cost |
|----------|------------|--------------|
| Simple FAQ | 500 | $0.003-$0.008 |
| Product question | 1,000 | $0.005-$0.015 |
| Technical support | 2,000 | $0.01-$0.03 |
| Complex consultation | 5,000 | $0.025-$0.075 |
Monthly Estimates
| Conversations/Month | Low ($3.75/M) | High ($15/M) |
|--------------------|---------------|--------------|
| 1,000 | $4-$8 | $15-$30 |
| 10,000 | $40-$75 | $150-$300 |
| 100,000 | $400-$750 | $1,500-$3,000 |

Watermark Removal
The "Powered by Assisters" Badge
Free tier embeds show a small badge. Many businesses prefer unbranded.
Removing the Watermark
When your wallet balance reaches **$50 or more**, you can enable watermark removal:
1. Go to Wallet settings
2. Toggle "Remove Watermark"
3. Your embeds now appear unbranded
The feature stays active as long as your balance stays above $50.
