Estimate Token Usage Before You Run It
Know how many tokens a job will consume before you send it — input plus an assumed response, costed per call and at scale.
Measure first, then trim. This counts a padded, over-polite prompt so you can see the tokens the filler is costing — before you cut it.
You cannot cut what you have not measured. This loads a deliberately verbose, please-and-thank-you prompt and counts it, so the cost of padding is a number rather than a feeling. Measurement is this tool's job; the actual trimming — removing redundancy and noise without changing meaning — is the Prompt Cleaner's. Used together, the loop is tight: count here, clean there, count again, and watch the per-1,000-calls figure drop.
Count the padded prompt
See what the filler and politeness are costing in tokens.
Trim with the Cleaner
Remove redundancy and noise without changing meaning.
Re-count
Measure again and watch the per-1,000-calls figure fall.
The report turns padding into a number: it counts the verbose prompt at roughly 176 tokens (range 158-193) and shows a per-1,000-calls cost line where token spend becomes real. Token Counter produces this browser estimate; the figures are character-based estimates, not tokenizer output, so treat them as approximate and verify pricing before relying on a number.
Only measures. Its job is counting; the actual trimming, removing redundancy and noise without changing meaning, is the Prompt Cleaner's. The loop is count here, clean there, count again, and watch the per-1,000-calls figure drop. It also isn't a fit check, the report notes for "will it fit?" the Context Window Estimator is the right tool.
No, they're estimates. The report shows the same text as roughly GPT-5 176, Claude Opus and Sonnet 184, Gemini Pro 176, but notes these are character-based estimates that tokenize differently per provider, which is why it gives a range rather than a single number. Pricing is approximate as of June 2026, so verify current rates before budgeting.
Know how many tokens a job will consume before you send it — input plus an assumed response, costed per call and at scale.
Paste a prompt, get an honest token estimate — a range, not a fake-precise number — plus the cost across GPT, Claude, and Gemini.
Turn a prompt into a dollar figure: input cost, output cost, combined per call, and the number that actually matters — cost per 1,000 calls.
Token budget planning for real workloads: how much of the window a transcript actually consumes, what is left for the answer, and how much headroom remains.
The "message too long" error has a structural fix: split at paragraph boundaries into sequenced chunks with wait rules, instead of pasting fragments and hoping.
A set of before-and-after examples showing exactly what prompt cleanup removes — and what it deliberately leaves alone.
Estimate how many tokens a prompt is and what it costs — honest ranges across GPT, Claude, and Gemini, with per-call and per-1,000-call pricing.
Cut what an AI feature costs without dumbing it down — price the prompt as it runs today, see where the tokens go, trim the waste, and re-measure to prove the saving holds at scale.
Counting a prompt's tokens before you send it tells you whether it fits the model, what it will cost, and whether the end might get cut off. Here's how to check and trim.
