Our Mission
Universal LLM Token and Cost Counter was created to solve a simple but important problem: developers and AI practitioners need an accurate, fast, and private way to understand token usage and costs across different LLM providers.
Before Universal LLM Token and Cost Counter, counting tokens typically required sending your data to external APIs or using provider-specific tools. This meant sharing potentially sensitive prompts, proprietary code, or confidential data with third parties.
We believe tokenization should be transparent, accessible, and private. That's why we built a tool that runs entirely in your browser — no servers, no data collection, no compromise.
100% Private
All processing happens in your browser. Your prompts, code, and files never leave your device.
Instant Results
Get real-time token counts and cost comparisons across all major LLM providers as you type.
Multi-Provider Support
Compare tokens and costs across OpenAI, Claude, Gemini, Llama, DeepSeek, Mistral, and more.
Accurate Token Counting
Using official tokenizers (tiktoken for OpenAI, llama3-tokenizer-js for Meta) and calibrated estimations for other providers.
Real-Time Cost Comparison
See input costs, output costs, and total API costs across flagship models from every major provider.
File Processing
Upload CSV, JSON, TXT, or LOG files up to 10 MB to tokenize entire datasets locally.
Token Visualization
See exactly how your text is split into tokens with our color-coded viewer.
Batch Processing
Process multiple prompts at once with our CSV/log batch upload feature.
Dark Mode
Easy on the eyes for late-night coding sessions.
Privacy First
We will never collect, sell, or share your data. Our architecture ensures your content stays on your device.
Accuracy Matters
We use official tokenizers where possible and provide transparent accuracy indicators for estimated models.
Free Forever
No sign-up, no API key, no limits. Universal LLM Token and Cost Counter is and will remain free for everyone.
Open Source
We leverage open-source tokenizers and tools. Transparency is at the core of everything we build.
