Plantoir

Plan the plot. Plant your notes. Grow a class website.

Turns a folder of Markdown notes into a fast, searchable class website.

Three overlapping windows in a diagonal cascade: Markdown notes in Obsidian on the left, Plantoir deploying the site in the middle, and the finished class website in Safari on the right.
From your notes in Obsidian, through Plantoir, to a live class website.

What it is

A plantoir is a dibber — the simple hand tool that opens a hole at the right depth so a seedling can be set in and take root. This app does the same for teaching materials.

Write in Obsidian, preview locally, deploy when you're ready. No content management system, no fifteen clicks to post a handout, and no platform holding your work hostage if you move schools.

How it works

  1. Add a course.
  2. Write your notes as Markdown files, in Obsidian or any text editor.
  3. Preview the site on your own machine, as often as you like.
  4. Deploy when you're ready. Your students get a real website.

What students see

Quick, searchable, and readable using a laptop or a phone.

Mathematics is typeset properly. Diagrams are drawn from your notes rather than pasted in as pictures. Every page can link to every other.

A Grade 10 mathematics worksheet on a class website: typeset equations, a diagram of two similar triangles drawn from the notes, folded answers, and a Print button beside the date.
Mathematics typeset, a diagram drawn from your notes, and a Print button.

A worksheet can print as a proper handout, and a graph is a few lines of text that students can drag. See how to write a handout and a diagram or a graph.

On the Mac. The Windows version gets this in a later release.

It helps you plan

Every course has curriculum expectations to cover, and tracking which ones you have addressed takes ongoing planning.

Plantoir answers that from the material itself. Tag a lesson with the expectations it addresses, and each build draws a map of the whole course — every expectation shaded by how many pages reach it.

A grid of every curriculum expectation in a course, each square shaded by how many pages address it, with pale squares showing the gaps.
Every expectation in the course, shaded by how well it is covered.

A course that answers to two curricula — the Ontario expectations and an AP framework, say — gets a map for each.

Because it's built from your own pages each time the site is built, it can't drift from the course the way a planning spreadsheet does. Useful throughout the school year, and ready whenever a department head or principal asks.
