Turn teaching materials and an optional example answer into grading instructions. Adjust them in ordinary language, paste a student's text or scan from WhatsApp or another source, and get an explained assessment. Compare revised submissions in the conversation. This workflow uses bundled Kvasir prompts and your available ChatGPT capabilities; no Kvasir account is needed. Register with Google at kvasir.pub for the full workspace: stored materials and editable instructions, submission versioning, stored results, and group processing. This plugin does not save or transfer chat content to Kvasir.
