Prompt whitespace token savings

Client

Normalize spacing on drafts and see how many rough tokens you might save. For full text stats use token estimate.

Draft text

?

Trims outer whitespace, strips trailing spaces on each line, and collapses three or more blank lines to one. Does not rewrite wording—only spacing.

  • Context window fit check — See if pasted text fits a 4K–1M token window with a rough CJK-aware heuristic—plan headroom before chat paste, browser-only. when you want a second pass with AI-assisted explanation on Toolcore.
  • Trim lines — Strip leading and trailing whitespace on each line—optionally remove empty lines locally. when you want a second pass with AI-assisted explanation on Toolcore.
  • LLM character budget from token cap — Plan max paste characters from a target token budget—same CJK-aware heuristic as token estimate, browser-only, not tokenizer-exact. when you want a second pass with AI-assisted explanation on Toolcore.

Common use cases

  • Shrink sloppy system prompts copied from docs without changing wording.
  • Preview token savings before applying normalization to a large template.
  • Pair with token estimate when you need exact before/after numbers in one view.

Common mistakes to avoid

  • Expecting semantic compression

    This tool only adjusts whitespace—it does not shorten sentences or remove content.

  • Removing intentional blank lines in code blocks

    Review normalized output; code fences may need manual fixes.

FAQ

Does this rewrite my prompt?

No. It trims edges, trailing spaces per line, and collapses runs of blank lines.

Are token savings exact?

They use the same rough heuristic as our token estimate page—not provider tokenizers.
