Custom Digital Flashcards
Create cards online and remember information via Telegram.
WitSlice helps you revisit material on a spaced repetition schedule — in small portions at a convenient time.
How it works
From first encounter to review: three steps that turn scattered facts into knowledge.
Spaced repetition means returning to material at planned intervals. You study a card, and WitSlice reminds you of it later to help it stick.
02 / STUDY
Learn in small parts
Each card focuses on one idea or question. Study at your own pace.
03 / REVIEW
Return to what you know
WitSlice creates a review schedule and sends cards to your chosen messenger.
A familiar format
Why Telegram
Cards and reminders arrive in a chat already on your phone. Open a message when it suits you and return to it later.
- No need to find another app for a quick review.
- Set the timing and frequency of notifications to fit your day.
- Messages stay available in your conversation.
