What does the Token Usage Optimizer estimate?
It estimates how many tokens a block of text will consume, plus the characters, words, lines, whitespace, and punctuation behind that estimate, and the estimated cost per selected model.
How to estimate token usage
Paste the text you want to measure into the primary input on the first screen and run the tool. Token Usage Optimizer reports a deterministic estimate of the tokens your text will consume, together with the characters, words, lines, whitespace, and punctuation that feed that estimate. The output reflects the actual text you supplied, so a longer prompt never produces the same estimate as a shorter one.
What the optimizer reports
Every run returns an evidence report with the input statistics, the estimated token count, the estimated cost per selected model, and the projected savings from the suggested optimizations. Estimates are computed with fixed character and morphology heuristics that run entirely in your browser, so the same input always produces the same numbers and the report never overstates what was measured.
Optimization suggestions
Alongside the estimate, the optimizer lists deterministic, actionable ways to lower your token usage: removing filler words and redundant phrases, compacting excess whitespace, reusing system prompts instead of repeating instructions, and tightening verbose sentences. Each suggestion shows an estimated saving so you can decide which edits are worth making before you paste the text back into your model.
How your inputs and reports are handled
All analysis runs locally in your browser against deterministic heuristics. No account, sign-in, or API key is required, and your text is never uploaded anywhere. The tool never publishes anything on your behalf: you decide whether to copy the report, download it, or share it. If you save a run, the record and its notes stay in your own browser storage.

Frequently Asked Questions
How are token estimates computed?
Estimates use fixed character and morphology heuristics that run locally in the browser, so the same input always produces the same deterministic result and no text ever leaves your device.
Do I need an account or an API key?
No. Paste your text into the primary input and run the optimizer. No account, sign-in, API key, or payment is required, and the tool works from the first screen.
Are the optimization suggestions reliable?
Suggestions are deterministic and derived from the text you supplied — filler-word removal, whitespace compaction, and system-prompt reuse — with estimated savings shown for each one.
Can I keep or share a report?
Yes. Every report can be copied as text or downloaded from the output area, and saved runs persist locally with notes. The tool never posts a report anywhere; sharing is always your own action.
