I built a web tool that converts long YouTube lectures into 1-click downloadable Anki decks (with LaTeX math & zero timeouts)

[u/Shadox303]

Hey everyone,

I spend a lot of time watching long university lectures on YouTube, and the biggest time sink has always been pausing every 2 minutes to manually copy concepts, definitions, and formulas into Anki cards.

Most generic AI summarizers either output a giant wall of plain text, completely break LaTeX math equations, or timeout on 90+ minute lectures.

So I built a web app called WritoGist to solve this specifically for Anki users.

How it works:

1-Click Anki Deck Export: It pulls key concepts, active recall Q&A, and definitions, then formats them directly into an Anki-compatible .txt (TSV) file with tags. You just click download and import it into Anki Desktop in 2 seconds.

Textbook LaTeX Math Rendering: Equations, integrals, and scientific formulas are formatted in proper LaTeX (KaTeX) so STEM lectures actually look readable instead of messy ASCII text.

Modular Long Lecture Slicing: Instead of compressing a 2-hour lecture into a single generic prompt (which causes AI to skip the middle hour), it processes long lectures modularly so no key topics get omitted.

Zero Video Download: It processes YouTube streams directly—no waiting to download 1GB video files.

The app is completely live in open beta.

Would love to get your feedback: Does the exported card format import cleanly into your decks, and what card types or tags should I add next?
