What is an AI token and why does it cost money?
Every time you type a message to ChatGPT, Claude, or Gemini, your text gets broken into small units called tokens. A token is roughly 4 characters or about ¾ of a word. AI models charge by the token — both for what you send and what they reply with.
For example, GPT-4o charges around $5 per million input tokens. A single long conversation can cost more than you'd expect. Without a token tracker, you're spending blind.
Stataz puts a live token counter directly inside your AI chat — so you always know exactly where you stand.
AI token calculator for ChatGPT (OpenAI)
ChatGPT is the most widely used AI tool in the world — and also one of the most expensive to use at scale. GPT-4o charges for both input and output tokens separately, which means a single back-and-forth conversation can add up fast.
Stataz adds a live token counter directly inside the ChatGPT interface. You can see your token count update in real time as you type, and track your cumulative usage across your session. No copy-pasting into a separate tool. No guessing.
- Live token count as you type
- Session total and per-message breakdown
- Cost estimate in USD based on current OpenAI pricing
AI token calculator for Claude (Anthropic)
Claude by Anthropic offers three model tiers — Haiku, Sonnet, and Opus — each with different token pricing. Haiku is the most affordable; Opus is the most capable. If you use Claude daily for writing, coding, or research, knowing which model you're spending tokens on matters.
Stataz tracks your token usage inside Claude.ai in real time, so you can see at a glance how much each conversation is costing you and when it might be worth switching to a lighter model.
- Works across Claude Haiku, Sonnet, and Opus
- Per-conversation token breakdown
- Cost estimate based on Anthropic's current pricing
AI token calculator for Gemini (Google)
Google's Gemini is growing fast — and for users on the Gemini Advanced or API tier, token costs matter. Gemini Pro processes both text and image inputs, which means your token usage can spike unexpectedly if you're working with multimodal content.
Stataz brings the same live token tracking experience to Gemini, giving you visibility across all three of your AI tools in one consistent interface.
- Tracks Gemini Pro and Gemini Advanced token usage
- Works with text and multimodal conversations
- Unified dashboard alongside ChatGPT and Claude data
Track your AI token price and estimate your monthly cost
Knowing today's token count is useful. Knowing your 7-day average is powerful. Stataz stores your token usage history so you can spot patterns — which days you use AI the most, which conversations cost the most, and where you could cut back.
Use the cost estimator to project your monthly AI spend before your bill arrives.
| Model | Tokens per day (est.) | Monthly cost (est.) |
|---|---|---|
| GPT-4o | 50,000 | ~$7.50 |
| Claude Sonnet | 50,000 | ~$9.00 |
| Gemini Pro | 50,000 | ~$3.50 |
* Estimates based on current published pricing. Actual cost depends on input/output ratio and model version.
