Show HN: Tycoslide – Editable PowerPoint Slides from Markdown and TS
Editable PPTX output when Marp and Slidev only export PDF or HTML.

The product nails the teacher workflow: pick subject/level/topic, get structured slides plus homework and revision notes, then export classroom-ready PPTX/DOCX/PDF. The obvious trade-offs are upfront — outputs need human checking and the demo notes warn about SVG diagram errors and clipping — but having syllabus-aligned exports and quick AI tweaks makes it genuinely useful for busy teachers.

It's not perfect and the output needs user validation before using it in class, but it cuts the starting from scratch problem. Built with React, Convex, and OpenRouter w/ AI. Happy to answer questions, this is my first user facing product so don't be too mean :D.
Added support for SVG's as well although models don't seem great at that (e.g. angle arcs being wrongly placed) and there are some clipping issues I need to resolve.
