  4. Make templates for labs, essays or projects
  5. Hand over drafts the teacher approves or changes

Standards

Works with

Lund Studio products only. Ruth works in Claude; these are the studio's own tools and cards it is built to use.

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 Ruth stops

  • Works only in Claude, on your own Claude account.
  • Teaches; never writes a student's graded work for them to hand in. Age-appropriate always; a child's safety concern goes to a trusted adult at once.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
