As answered by people managing Tokensave.app and Diffee.
Tokensave.app's answer
Developers and teams building on LLM APIs who want to estimate costs, people deciding between ChatGPT Plus, Claude Pro or Google AI Pro and the API, developers using coding agents like Claude Code and Codex, and non-English users who want to know how much extra their language costs.
Tokensave.app's answer
It puts every AI cost question in one free place: tokens and API cost for GPT, Claude and Gemini side by side, whether a subscription or the API is cheaper for you, what coding agents like Claude Code and Codex cost per month, and the price of AI video and images. It also shows how much more non-English text costs (Korean needs about 44% more tokens than English on GPT, Japanese about 79% more) and can translate a prompt to English on your device to save tokens. It runs in 41 languages, and nothing you paste leaves your browser.
Tokensave.app's answer
Most token counters cover one model family and stop at the token count. AI Token Counter compares GPT, Claude and Gemini at once, turns tokens into money with prices updated daily, and goes further: subscription vs API, coding agent costs, and video and image prices. It is completely free, needs no account, and your text is never uploaded.
Tokensave.app's answer
I'm a solo developer who builds mobile games with AI, without a coding background. While working with Claude and other models, I kept wondering what each prompt really cost and whether my subscription was worth it. When I measured the same prompt in 41 languages, I found that non-English text often needs far more tokens than English. So I built a free tool to make those costs visible, and it grew into a set of calculators.
Tokensave.app's answer
A static site built with Python and plain JavaScript, styled with Tailwind CSS and hosted on GitHub Pages. Tokens are counted in the browser with tiktoken-compatible tokenizers, and prompt translation uses the browser's built-in Translator API, so no text is sent to a server. API prices are refreshed daily by a GitHub Actions workflow.
