Process locally in your browser. Inputs: Text or prompt to tokenize, Target Model Family, Input Price ($/1M tokens), Output Price ($/1M tokens). Outputs: Total token count, Visual token boundaries, Estimated API cost, Character & word statistics.
How to use it?
Provide the listed input and choose Execute. Review the result, then copy or download where available. Clear removes inputs and results.
Browser-local processing. No uploads, content logging, persistence or remote resource loading. Generated markup is inert text; files are treated as untrusted data.
100% in-browser AI & prompt processing. Token estimation, JSON repair, vector metrics, and prompt construction run entirely in client memory with zero server uploads or external LLM API calls.
Inspect multi-model token counts across GPT-4o, Claude 3.5, Gemini 1.5, Llama 3, and generic BPE with visual token boundaries and cost estimation per 1M tokens.
