About these tools
These AI tools are calculators and estimators that run entirely in your browser. They help you plan ahead — work out how many tokens a prompt will use, estimate what an API call or a month of chatbot traffic might cost, and compare the trade-offs between models before you commit. Nothing here runs an AI model or sends your data anywhere.
The lineup covers the numbers that decide a project budget: an AI Token Calculator and a Tokens to Words Converter for sizing prompts, an LLM API Cost Calculator and Chatbot Cost Calculator for ongoing spend, plus Embedding, Fine-Tuning, and AI Image Cost Calculators for one-off jobs. A GPU VRAM Calculator helps you check whether a model will fit on the hardware you have.
Because every estimate is computed locally, you can change assumptions freely and see the impact instantly without an account or any upload. Treat the results as planning figures rather than invoices: real provider pricing and tokenization can shift, so confirm the current rates before you ship a budget.
Frequently asked questions
No. They are calculators and estimators that compute token counts, costs, and hardware requirements in your browser. They do not generate text or images, run any model, or send your inputs to a server.
They are planning estimates based on the rates and assumptions you enter. Tokenization and provider pricing vary by model and change over time, so check the current published prices before relying on a number for a budget.
A token is a chunk of text — roughly a few characters — that language models read and write in. Most API pricing is per token, so estimating token counts is the most direct way to estimate cost. The Tokens to Words Converter helps translate between the two.
No. The calculations happen on your device and the numbers you enter stay in your browser. There is no account, no upload, and nothing is saved on a server.
