LLM Token Counter & API Cost Calculator (Multi-Model)
Don't get surprised by your API bill. Paste your prompt to estimate the token count and API costs for popular models like GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Flash.
Why Use This Private Token Counter?
Your Prompts Stay Private (Client-Side)
When working on sensitive code or proprietary business data, you cannot risk pasting it into public online tokenizers that might log your data. Pixedra runs locally in your browser. Your prompts are counted using local JavaScript libraries. We do not send your text to OpenAI, Anthropic, or our own servers.
Compare API Costs in Real-Time
Stop switching between pricing pages. We update our cost database regularly to reflect the official pricing per 1M tokens. Instantly see if it's cheaper to run your prompt on GPT-4o vs Claude 3.5 Sonnet.
Accurate BPE Tokenization
We use standard Byte-Pair Encoding (BPE) logic similar to OpenAI's own `tiktoken` library to ensure the counts are accurate for modern Large Language Models (LLMs).
Supported Models & Pricing Logic
We currently support cost estimation for the following major models:
