Workflow, boundaries, sources, and common questions in one compact block.
Reddit questions about AI costs are rarely just about counting tokens. They are usually about why output gets expensive, how fast chat history grows, and which model is cheap enough for testing.
The calculator shows your prompt and planned answer separately. That reveals whether cost comes from the long document or the expected model response.
Free models, cheap paid models, context windows, and price per request sit side by side so budget decisions are faster.
The tool does not send your prompt to a model. It estimates locally and only uses public model data.
