International school leader building tools for teachers.
I build software to solve problems that teachers and school leaders run into at work. The tools here run on your device, so student data stays out of the cloud. I also lead research into how AI affects classroom practice, and run practical workshops for educators.

Tools
Small tools for classroom and school admin work. They run entirely in your browser, including the AI tools.
- NEW
Daily Journal
A daily notebook with one plain Markdown page per day. Everything stays on your device.
QR Generator
I use this to make QR codes for presentations and classroom materials.
Resource Library
A searchable home for the teaching resources I find online.
Flashcard Maker
A simple way to create printable flashcards for my students.
- NEW
Image Converter
I use this to resize and convert iPhone and iPad photos for my newsletter.
Prompt Masker
Removes student details from AI prompts before they leave your device.
Report Checker
Checks school reports for common errors and inconsistent wording.
Report Writer
An AI assistant for drafting personalised student reports.
Text Differentiator
Adjusts a text to a different reading age for EAL students.

Name Trainer
Photo games that help me learn my students' names at the start of term.

Group Maker
Splits a class into balanced groups, with rules for students who should or shouldn't sit together.

Random Picker
Keeps track of who has had a turn, so I do not keep picking the same hands.

16 sites with copyright-free video footage for iMovie projects
Finding free footage to include in your iMovie projects is easy, but finding footage that students are actually allowed to use, is free, in HD quality and doesn’t require registration can be another story. Here is a list of websites that I regularly tell my students to use to download quality video footage from.

ImageOptim – A great lossless image optimiser
ImageOptim is a great piece of free software (open-source, and free) to reduce the amount of space an image takes up on a hard drive, without any loss in quality.
Why I share my work
Publishing a tool forces me to finish it properly. I build these for myself and my colleagues. If one saves you some time too, good.
Your data stays put
Free tools should not cost you your privacy. These tools run on your device and do not send your data to my servers.
They work offline
A classroom connection is not always reliable. Load a tool once and you can keep using it without internet access.
Free
Teachers already buy too many classroom supplies themselves. I do not charge for these tools or track their users. The code is not open source, and I have no plans to make it so.
