Plain Language Rewriter

Testing whether a model can rewrite dense administrative text into clearer language without changing its meaning.

Hypothesis

A constrained rewriting prompt plus a meaning-check step produces clearer text that reviewers accept more often.

Problem

Official wording is often accurate but difficult for the intended reader.

Experiment design

  • Define a fixed reading-level and terminology constraint
  • Generate a rewrite alongside a diff of changed terms
  • Run a second pass that flags possible meaning changes
  • Require an editor to accept or reject each paragraph

Technology and technique

Constrained rewriting with a verification pass.

Human involvement

A person reviews and approves the model's output before it is used. The AI drafts; the reviewer decides.

Result

Clarity improved on most samples; edge cases needed an editor in every run.

Limitations

  • The verification pass catches obvious meaning drift, not subtle legal nuance.
  • Domain terms still need a human glossary.

Ethics and privacy

Sample text is written for the experiment and contains no real records.

Rewrites are never published automatically; legal or policy text always needs a qualified reviewer.

Next step

Build a reusable glossary so terminology stays consistent across documents.
