The Problem

Creating flashcards manually takes hours, longer than actual studying

Current Solutions (Not Great)

Manually create Anki cards, use pre-made decks that don't fit

Who Needs This

Students, lifelong learners, certification preppers

Paste your lecture notes, textbook chapters, or any content and instantly get a deck of study flashcards. Built-in spaced repetition helps you remember. Export to Anki or study right in the app.

Honest Take

Strong product-market fit—students hate making flashcards and Anki's learning curve is brutal. This space is heating up fast with RemNote, Quizlet AI, and others. Anki export is smart—lean into the ecosystem rather than competing. Med students and language learners are your best early adopters.

Build Prompt
Use this prompt with an AI assistant to start building
Build a React PWA called 'Instacards' using WebInfer for AI inference. UI: large textarea for pasting notes/content, or file upload for PDF/images. Use generateObject with schema { cards: [{ front: string, back: string, difficulty: 'easy' | 'medium' | 'hard', tags: string[] }] } to generate flashcards. Show cards in editable grid, click to flip preview. Edit/delete individual cards inline. Study mode: show front, user clicks to reveal back, rate (again, hard, good, easy) for spaced repetition. Track cards due using localStorage. Export button generates Anki-compatible .txt file (tab-separated). Add 'Generate more cards' button for dense content. Progress stats: cards studied today, streak, mastery percentage.
