Free token estimator

Estimate Claude Code context before you send it

A browser token estimate is useful for comparing two versions of context, but it cannot reproduce every provider tokenizer or hidden system component. Paste the visible content you control to identify unusually large files, logs, instructions or history, then verify the final request with provider-reported usage.

Results vary by workload. Provider prices and limits remain controlled by the provider.

Good uses for an estimate

Compare a full log with a filtered log, a long tool description with a concise one, or an entire conversation with a factual summary. The relative difference can guide testing even when the exact token number differs from the provider.

What the estimate cannot see

Claude Code may add system behavior, project context, tool metadata and internal state not present in the text box. Tokenization also changes with content and model. Do not use a character ratio as an accounting record.

Local token estimate

This is an approximate comparison, not provider billing data.

Move from estimate to evidence

Varion keeps its proprietary engine implementation private. Commercial evaluation is based on measurable workload-specific outcomes, clear validation boundaries and customer-specific testing rather than disclosure of internal mechanisms. Use the dedicated Token Optimisation product area to evaluate whether the commercial result is suitable for your traffic; no universal performance percentage is promised.

Measurement checklist

  1. Choose a representative completed task, not an artificial one-line prompt.
  2. Record the selected model, provider input, cached input, output, retries and final result.
  3. Change one optimization mechanism at a time so the cause remains visible.
  4. Verify required identifiers, tool calls, code changes or business fields.
  5. Keep passthrough available when the reduced request does not pass.

Varion commercial evaluation

Varion keeps proprietary product implementation details private. Evaluate Token Optimisation on representative traffic and judge it by the measured commercial result. New verified users receive 100,000 processed input tokens and 50 local test runs.

Frequently asked questions

How accurate is the calculator?

It is a rough text estimate for comparison. Provider-reported usage is the source of truth.

Does code tokenize differently from prose?

Yes. Symbols, whitespace, identifiers and language can affect tokenization.
