Lecture slides from your lesson plan, ready before the bell.
Decklume turns notes, a syllabus or an old PowerPoint into a teaching deck with definitions, worked steps and reveal-one-point-at-a-time builds, in a theme built for reading from the back row.

What you can make
Copy a prompt, change the details, paste it into Claude Code.
- Lectures from notes
Turn my notes in week-5.md into a 40-minute lecture for first-year economics, with a recap slide every 10 minutes.- Revision decks
Make a 15-slide revision deck on photosynthesis for 9th grade using the Chalk theme, one definition per slide.- Converted PowerPoints
Convert lecture-04.pptx into a Campus-themed deck and keep all my speaker notes and charts.- Workshop and training
Build a 90-minute teacher-training workshop deck with activities, timings and discussion prompts.
Why it works for teachers
- Definitions and formulas
- A dedicated definition layout with pronunciation, examples and native MathML for equations.
- Reveal one point at a time
- Builds show points in order and dim earlier ones, so the class follows along.
- Readable from the back
- Body text stays at 24 px or larger on the 1920×1080 canvas, and every theme passes WCAG AA contrast checks.
- Reuse your PowerPoints
- Import .pptx files with bullet levels, tables, images, notes and native chart data intact.
Themes to start with

Questions
Can Decklume convert my existing PowerPoint lectures?
Yes. It extracts text with bullet levels, tables, images (including grouped ones), speaker notes and native chart data, then redesigns the deck in the theme you choose.
Do the slides work on a classroom projector?
Yes. Slides stay at 16:9 on any screen and scale as a whole, so nothing reflows on a projector, laptop or phone.
Can students get a copy?
Export a PDF handout, PNG images of each slide, or deploy the deck to a link that works on any device.
Is there a theme for younger students?
Bloom is warm and playful, and Chalk looks like a classroom blackboard. Both pass the same accessibility checks as every other theme.
