Look before you run.
Estimate the size of your input and see how much of a context window it occupies. Find the heavy parts before they become a bill.
OPEN-ACCESS TOKEN INTELLIGENCE
Make every
token count.
Intelligence is precious. Wasted context isn’t.
See what your prompt costs before it runs—and give your best ideas more room to think.

01THE CONTEXT PLAYGROUND
A little foresight.
A lot less overhead.
Drop in a prompt. Inspect its footprint.
Start making deliberate decisions about every token you send.
ⓘ
Local heuristic estimates, not a provider tokenizer. Cleanup removes exact repeated lines and excess whitespace; review the preview before using it. No model is called.
02A MORE DELIBERATE PIPELINE
The smartest token
is the one you
didn’t need.
Context grows quietly. A repeated instruction here. A stale memory there. We make that invisible overhead visible—before you hit send.
See your context differentlyGive repetition an exit.
Compare your original context with a lighter version. Remove exact duplicates and unnecessary spacing, with every change available for review.
Know the shape of the cost.
Bring your own rates. Adjust request volume and output length. Turn a token count into a budget you can reason about.

04BUILT WITH A SMALLER FOOTPRINT IN MIND
Big ideas shouldn’t
need big budgets.
SaveYourToken began with a simple question: how much computation could we avoid if we understood our context first? An open-access project for students, independent developers, and everyone building with limited resources and unlimited curiosity.

05A FEW GOOD QUESTIONS
Under the hood.
Does my context leave my browser?
No. This page processes your text locally. It doesn’t send prompts to an AI provider, store them on a server, or require an API key. Fonts may load from Google Fonts; your context is not part of those requests.
Are these exact token counts?
They are heuristic estimates based on text length and character types. Actual token counts depend on the model’s tokenizer, message formatting, and tool definitions. Use your provider’s tokenizer for exact billing or context limits.
What does context cleanup change?
It trims trailing whitespace, collapses excess blank lines, and removes exact repeated lines longer than 40 characters. It does not understand intent or summarize meaning. Repetition can be intentional—always review the cleaned preview.
Can I use my own model pricing?
Yes. Enter input and output prices per million tokens, the expected output length, and monthly request volume. The cost explorer recomputes immediately using your current context.
LESS WASTE. MORE ROOM TO BUILD.
Your next great idea.
Fewer tokens away.
