Create, Grade and Personalize learning

This is the record of what shipped between the start of May and the first week of July, kept in Keep a Changelog form. Two asks from teachers ran through all of it: mark a whole class in one pass, and show me the whole class in one view. Everything below is one of those two, or the plumbing they stand on.

1 to 22 May: bulk grading and AI authoring​

Mark a whole class set against your rubric in one pass, draft lessons and questions with AI, and take the results out of Zippy.

Added

  • Bulk grading, with an inline evaluation editor.
  • An AI authoring flow for lessons and questions.
  • Export submissions as PDF, DOCX, or Markdown.

Changed

  • A unified grading page with a shared roster sidebar.

Fixed

  • Made the editor and learner views mobile-friendly.

24 May: the platform grows a public surface (CLI v0.1.2)​

The first pieces of Zippy you can install without asking us: a versioned CLI, an extractable client library, MCP servers, and the first mobile build.

Added

  • The zippy-client library with a public surface.
  • Model Context Protocol servers, including a student-scoped server and asset tools.
  • Zippy Mobile, phase 1.
  • Open-source skills rewritten as Claude Code skills under an MIT licence.

Changed

11 to 23 June: the classroom gradebook​

See your whole class in one view. Grading collapses to one screen, and the classroom gets a gradebook and a monitor.

Added

  • A classroom teacher view: gradebook, monitor, and submissions.
  • A feedback split with inline annotations and a one-column grading config.
  • Structured comments and next steps, with per-rubric parallel evaluation.
  • A live grader demo with grading progress.
  • Product analytics.

Changed

  • Grading redesigned to a one-screen create with in-page import.
  • A typed question model and a unified grading pipeline with deterministic auto-grade.

Fixed

  • Submission reliability: no duplicate records, no stale spinner, and per-submission delete.
  • Retry for submissions that fail to process.

24 to 30 June: Discover library and standards-driven grading​

Pull ready-made content and grade against standards without hand-building every rubric.

Added

  • A redesigned Discover library with self-service grading presets and a quiz flow.
  • A read-only content preview for library items.
  • Standard-driven grading via assessment packs.
  • Math and physics question types with curriculum-grounded generation.
  • Inline skills rubrics with skill-map resolution.

Changed

  • Library clone gets soft-delete revive and a simpler overwrite flow.
  • Editor authoring, with bulk submissions and objective auto-grading.

Fixed

  • Two-phase save (draft then publish), so saving never throws a duplicate-id error.
  • Answer edits no longer target the wrong row on re-graded submissions.

1 to 7 July: mobile import and generation reliability​

Getting work into Zippy from a phone was slower than marking it. This week was the unglamorous fixes.

Added

  • A prominent Add new import button above the roster.
  • A mobile-optimised import layout with tap-select and bottom sheets.

Changed

  • The AI panel preloads the lesson-editing skill to cut latency.

Fixed

  • Repaired the lesson-generation plan-to-generate path.
  • Overhauled native PDF and DOCX export, with a crash fix and stale-rubric re-runs.
  • Recovery when a login session gets stuck.

Honest about what this is​

Every line here describes what the software does: it drafts, it grades a first pass, it exports, it tracks patterns. None of it is a claim about measured learning outcomes, because that is not ours to claim yet. The teacher reviews and releases everything the grader writes.

The next instalment is What shipped in July. All release posts live under the release tag, and the open-source CLI and skills are at github.com/heyzippy/zippy.
