🤖 AI Token Counter & Cost Estimator
Count tokens and estimate costs across GPT-4o, Claude 3.5, DeepSeek, Gemini, and more. Know your API costs before you call.
| Model | Input (1K) | Output (1K) | Est. Input | Est. Output |
|---|
* Prices as of June 2026. Token count is estimated (~4 chars/token for English, ~2 for non-Latin). For exact counts use tiktoken.
📋 When to Use the AI Token Counter & Cost Estimator
The AI Token Counter & Cost Estimator fits into your daily workflow whenever you need a quick productivity boost. Use it during focused work sessions, between meetings, or as part of your regular toolkit. It's designed for professionals who value efficiency — project managers, developers, writers, and anyone juggling multiple tasks. No account setup, no learning curve — just open the page and get things done.
⚙️ How the AI Token Counter & Cost Estimator Works
The AI Token Counter & Cost Estimator operates as a single-page application in your browser. When you interact with the controls — buttons, inputs, timers — JavaScript event handlers respond instantly, updating the DOM (Document Object Model) without page reloads. State is managed in memory and optionally persisted to localStorage so you can pick up where you left off. The tool uses the browser's built-in timing APIs (setTimeout, setInterval, requestAnimationFrame) for accurate tracking and responsive feedback.
How to Use the AI Token Counter
- Paste your text — Drop any prompt, conversation, or document into the text area. The tool analyzes it instantly.
- Check your stats — View character count, word count, estimated tokens, and detected language (English vs multi-language).
- Compare costs — The cost table shows estimated API pricing for 12 models: GPT-4o, Claude, DeepSeek, Gemini, Grok, and Llama.
- Budget your calls — Use the cost estimates to decide which model fits your budget before making expensive API requests.
Frequently Asked Questions
How accurate is the token count?
Token counts use character-based estimation: ~4 characters = 1 token for English, ~2.5 for non-Latin scripts. This is ~85-90% accurate. For exact counts, use the model's official tokenizer (e.g., tiktoken for OpenAI).
Are the API prices up to date?
Prices are current as of June 2026. API pricing changes frequently — verify with the provider before production use.
Why do input and output have different prices?
Most AI providers charge more for output tokens because generating text is more computationally expensive than processing input.
Does this work for non-English text?
Yes! The tool detects when >30% of characters are non-Latin and adjusts the token ratio accordingly.
