Free tools, built for the classroom.
Welcome — these tools are designed to help your teaching workflows. I'm a primary school teacher who also builds software, and I make the tools I wish I'd had from the start: free, and built around how a classroom actually runs.
- Gap Finder
- Word Checks A & B
- Lesson Builder
Structured Literacy planning, from word check to lesson plan.
Codeline is a daily reference, assessment and lesson-planning tool for the Structured Literacy Programme, built around word checks. Paste in the words a student is getting wrong and it matches each one against the year-level word checks, tells you the pattern and year it belongs to, and can build a printable catch-up lesson — learning intention, success criteria and curriculum link included. It also includes the full literacy reference by year, print-ready word-check assessments and word lists, a five-step Lesson Builder, and a set of Structured Literacy novel studies for Years 4–6.

The whole maths curriculum, at a glance.
Chalkline is a free planning reference covering all mathematics concepts across Years 1–8 of the New Zealand Curriculum. Every concept comes with a plain-language description, the order to teach it in, what needs to be secure first, diagnostic checks, materials and worked examples — mapped onto both the 2026 Mathematics and Statistics learning area and the 2007 curriculum levels and Number Framework stages.

Open Chalkline →A calm way to bring current events into the classroom.
Compass World News is a privacy-first news reader I built after noticing how hard it can be to find balanced coverage for classroom discussion. It groups reporting on the same story from across the political spectrum, so students — and teachers prepping a current-events lesson — can see how different outlets are framing the same event, rather than reading from a single source.
A political lean dial lets you see where a story sits across the spectrum, and blindspot mode surfaces stories one side has barely covered — useful for teaching media literacy and critical reading of the news. It's ad-free and doesn't track you, with no account required.
