AI presentation maker for teachers lesson slides from a topic or your notes

1. Start from what you already have. Type a topic ("photosynthesis for 12-year-olds", "causes of the First World War"), paste your course notes, or drop a PDF, Word (.docx), Excel or PowerPoint file into the single box.
2. Choose the length. 5 to 35 slides: a short starter for a 10-minute introduction, or a full sequence for a double period.
3. Check and adjust in the browser. Edit any text or figure, rewrite a definition at your class's level, switch the theme in one click.
4. Take it to class. Export an editable .pptx that opens in PowerPoint, Google Slides or Keynote.

Ask for a lesson and say how you want it taught, for example: "start with a big question, define the key concept, show the steps, give a worked example, end with a recap". Slidy has layouts that match these moments of a lesson:

• Big question: a statement or quote slide to open the discussion.
• Key concept: a short definition with a photo from a free library, credited.
• Steps: a step-by-step process slide (a method, an experiment, a proof).
• Context: a timeline for history or the history of a discovery.
• Compare: a comparison table or a 2x2 matrix (two characters, two systems, pros and cons).
• Recap: key points to copy down before the bell.

Slidy never invents numbers. Figures come only from the text or file you give it; when a slide needs a figure you did not provide, it shows "XX" so you fill it in yourself rather than teach a made-up date or percentage. Slides are written in the language of your topic or document, so a French, Spanish or German class gets slides in that language. The interface itself is in English. As with any AI tool, read the deck before you present it: you remain the subject expert.

Good fit: a teacher who builds lessons alone and wants a first draft fast, from a topic or existing notes, and only pays for the decks they keep as PowerPoint.

Not a fit: Slidy has no real-time co-editing, no comments, no shared team or school workspace and no brand kit, and the PowerPoint download is not free. If your department builds decks together every week, a subscription tool will suit you better. Starting from a handout? See PDF to PowerPoint and Word to PowerPoint.
