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

The problemCanadian 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 doesPigeon 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 coverage30,413 curriculum standards collected from official provincial curriculum websites13 provinces and territories7 subjects: Mathematicas, English Language Arts, Science, Social Studies, Arts Education, Physical & Health Education, Core FrenchGrades 1–12English and French output, written at the correct grade reading level rather than machine-translatedA built-in Curriculum Browser lets teachers search standards by province, subject, and grade, and generate a worksheet directly from any outcome.Material typesTeachers choose what kind of material to create:TypeWhat it producesPractice WorksheetQuestions, word problems, and exercises with an answer keyReading ComprehensionAn original passage with follow-up analysis questionsNarrative Writing PackBrainstorming tools, story planning, and drafting spaceLesson OutlineStructured teaching points for introducing a conceptBrainstorming TemplateGraphic organizers, mind maps, idea-generation toolsVocabulary BuilderDefinitions, sentence matching, context-clue exercisesGenerated question formats include multiple choice, short answer, open ended, fill-in-the-blank, true/false, matching, and word problems.Worksheet editor — capabilitiesGeneration is a starting point, not the deliverable.
