Re:Skill to Create Flashcards on Monday June 15, 2026 @05:03AM (#48538550)
Hey, I created a skill that allows you to easily create flashcards with Claude Code / Codex. It contains the best practices on flashcards and gives the llm an explanation on how to use Space. Space is my flashcards app that I started building 7 years ago. It's free, multi-device and you own the data. I hope this is useful to some

Yes the current image editing was not made for image occlusion and feels cumbersome for that. I will think about it. Thank you!

No it currently doesn‘t do it. It’s basically an easy way to access the SQLite database. You could tell Claude Code/Codex to find them and delete them. They would then immediately delete in the app

I will probably add any easy way to detect them in the app. Is there any advantage to do it in the cli?

Yes, there are many differences to a 1-shotted flashcard implementation:

- modern UI & UX

- offline-first mode

- your data belongs to you. You can either use the export function or use the CLI to export in every format you want

- subdecks (only nested to one depth, so that the UI is not confusing)

- images, videos and latex support

- work on decks with friends or share them with the world

- runs on iOS, Android, Windows, macOS and Linux

- latest algorithm FSRS6

- everything is free, except optional AI.

Hey, I created seven years ago a flashcard app with a main focus on UX. In the last months I added offline-first mode and a CLI that allows Claude Code or Codex to create high quality flashcards for you. I use that to learn about pharma rules, technology, dancing, taxes and smart home. Never really did marketing, this not my specialty. Would love to know what you think

I found this 13 min explanation very helpful in understanding backpropagation (https://youtu.be/c36lUUr864M?t=2520).

First he explains the necessary concepts:

1) Chain Rule

2) Computational Graph

Then he explains backpropagation in these three steps (first in general and then with examples):

1) Forward pass: Compute loss

2) Compute local gradients

3) Backward pass: Compute dLoss/dWeights using the Chain Rule

A spaced repetition flashcard app with the main focus on creating flashcards together. Sharing is still missing, but we are starting to work on it: https://play.google.com/store/apps/details?id=com.space.spac... or https://apps.apple.com/us/app/space-spaced-repetition/id1546....

I'm still a student and started programming the app with a friend because I wanted to learn physics with my classmates. But the other apps Anki, Brainscape and Quizlet have a pretty bad UX to create flashcards collaboratively, so I started working on it.
