Pigeon Lab — AI-Powered Worksheets for Teachers - Sell Project

The problem Canadian teachers spend hours each week building practice materials from scratch. Generic worksheet sites are written to American standards, so the content does not line up with what a teacher in Quebec, Ontario, or British Columbia is actually required to teach. General-purpose AI chatbots produce text that still needs to be reformatted into something printable. What Pigeon Lab does Pigeon Lab is a curriculum-first authoring tool. It combines a database of real provincial curriculum outcomes with AI generation and a purpose-built document editor, so a teacher goes from "I need to teach main idea to Grade 4" to a printed worksheet in about two minutes. Curriculum coverage 30,413 curriculum standards collected from official provincial curriculum websites 13 provinces and territories 7 subjects: Mathematicas, English Language Arts, Science, Social Studies, Arts Education, Physical & Health Education, Core French Grades 1–12 English and French output, written at the correct grade reading level rather than machine-translated A built-in Curriculum Browser lets teachers search standards by province, subject, and grade, and generate a worksheet directly from any outcome. Material types Teachers choose what kind of material to create: TypeWhat it produces Practice WorksheetQuestions, word problems, and exercises with an answer key Reading ComprehensionAn original passage with follow-up analysis questions Narrative Writing PackBrainstorming tools, story planning, and drafting space Lesson OutlineStructured teaching points for introducing a concept Brainstorming TemplateGraphic organizers, mind maps, idea-generation tools Vocabulary BuilderDefinitions, sentence matching, context-clue exercises Generated question formats include multiple choice, short answer, open ended, fill-in-the-blank, true/false, matching, and word problems. Worksheet editor — capabilities Generation is a starting point, not the deliverable. Every worksheet opens in a block-based editor built on TipTap/ProseMirror, giving teachers full editorial control before anything reaches students. Document blocks — inserted via a slash menu or the mobile insert button: Question blocks — editable prompts, options, points, and answer key entry Math blocks — LaTeX equations rendered with KaTeX Image blocks — upload an image or generate one with AI, with layout control Tables — full table editing with header rows and cells Callout blocks — highlighted instruction or tip boxes Work areas — configurable blank space for student work (lined, grid, blank) Signature lines — parent/guardian sign-off lines Spacers — fine-grained vertical spacing control Page breaks — explicit control over what lands on which printed page Banner section — worksheet header with title and optional banner image Text formatting: bold, italic, underline, strikethrough, inline code, links, text colour, highlight, font size, and left/centre/right alignment. AI editing assistance, applied in place: Regenerate a question — swap a single question for a fresh one testing the same skill, without touching the rest of the document Differentiate — produce an easier or harder version of the whole worksheet for mixed-ability classrooms, preserving topic and structure Generate an image for a specific question or the worksheet banner Document handling: Drag-and-drop reordering of blocks Live paper preview showing exact printed pagination Automatic saving as the teacher works Worksheet history, so past materials can be reopened and reused Export and sharing PDF export with print-accurate layout Word (.docx) export for teachers who need to edit in Word Direct printing with page-break control and background graphics preserved Share links — a tokenized read-only URL for colleagues or students Business model Subscription, sold directly to individual teachers.
