Abbreviation First-use Auditor

How to use Abbreviation First-use Auditor

A glossary does not tell you whether a reader meets an unexplained short form first. Supply your own exact labels and expansions, then inspect their earliest use and exact expansion pattern. The tool reports source evidence for an editorial decision rather than guessing a dictionary or claiming every abbreviation needs a definition.

1. Paste a plain excerpt and your own exact abbreviation glossary.
2. Choose long form (ABC) or ABC (long form), then run the check.
3. Review each first occurrence, missing expansion and author-declared exemption; export the source evidence.

Good to know

• At most 100,000 well-formed UTF-16 source characters, 100 glossary rows and 5,000 total abbreviation occurrences. Glossary text is capped at 40,000 characters; each expansion at 300.
• Labels are unique ASCII uppercase strings beginning with a letter and containing 2–16 letters/digits. Every TSV row has exactly three fields: label, nonblank expansion and required/exempt. Matching is exact case with Unicode letter/mark/number/underscore token boundaries.
• Only the exact selected parenthetical expansion is recognized. No acronym discovery, dictionary lookup, inflection/plural recovery, case inference, HTML/Markdown parsing or checking that the expansion is factually correct is performed. Code, quotations and headings remain literal source text.
• Offsets are zero-based UTF-16 positions. NFC and NFD remain different. An unused or author-exempt term is reported separately; a clean selected check does not establish a complete style, accessibility or editorial review.
• Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
