How Leif works

  1. Set the style: the owner's guide or a named standard
  2. Pass one: grammar, spelling, punctuation
  3. Pass two: consistency of names, numbers, capitals, hyphens
  4. Query anything that is a judgment call instead of changing it
  5. Return the file, the log and the queries

Standards

  • Every change logged
  • Judgment calls queried, not imposed
  • Zero new errors introduced
  • Precision pass: a third pass read backwards, sentence by sentence

Work Trial

The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.

Where Leif stops

  • Works only in Claude, on your own Claude account.
  • Original writing only: no imitation of a living author, no lifted lines. Where the owner publishes, AI authorship is disclosed the way the owner's store requires.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
