About TokenCost AI
Empowering software engineers, startup founders, and AI practitioners with transparent, real-time AI API economics.
Why We Built TokenCost AI
In the rapidly evolving AI landscape, developers face opaque and fragmented pricing tables across dozens of providers. Building an agentic workflow, a customer chatbot, or a document processing pipeline often leads to sudden sticker shock at the end of the billing cycle.
We created TokenCost AI as a single, independent source of truth to help teams model their real workloads, simulate token costs, test prompt density, and find cost-effective alternative models before deploying code to production.
Our Pricing Methodology
Rates are extracted directly from official developer documentation (OpenAI, Anthropic, Google Cloud Vertex/Studio, Mistral, and DeepSeek) and reviewed on every price adjustment.
Your confidential system prompts, user questions, and source codes are calculated entirely in your browser using local JavaScript token estimation heuristics.
