Custom Digital Flashcards
Create cards online and remember information via Telegram.
WitSlice brings material back on a spaced-repetition schedule — in small portions, whenever it suits you.
How it works
From the 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 about it later to help fix the information in memory.
02 / LEARNING
Learn in small pieces
Each card focuses on one idea or question. Work through the material at your own pace.
03 / REVIEW
Return to your knowledge
WitSlice builds a review schedule and sends cards to your chosen messenger.
A familiar format
Why Telegram
Cards and reminders arrive in a chat that is already on your phone. Open a message whenever it is convenient and return to it later.
- No need to find and open a separate app for a quick review.
- Set the timing and frequency of notifications around your day.
- Messages remain available in the conversation.
