FAQ

Frequently asked questions

Yes. Everything — PDF/text generation, unlimited decks, SM-2 spaced repetition, cloze deletion, printing, PDF export, and CSV/JSON import/export — is completely free with no signup and no ads.
Scroll to the Generator section, click the "From PDF" tab, drop your PDF file, and click "Generate Flashcards." The app extracts text and creates editable Q&A cards. You can review and edit them before saving.
Cloze deletion turns a sentence into a fill-in-the-blank card. Wrap the answer in double curly braces or double square brackets. Example: The capital of France is {{Paris}}. During study, the front shows "The capital of France is [ ... ]" and the back reveals the answer highlighted. This is often faster and more effective than splitting sentences.
Yes. Flashcard.online is a free, browser-based Anki alternative. It works instantly in your browser without installation, supports PDF-to-flashcard generation and cloze deletion, and offers print/PDF export. You can import and export CSV files to move data between tools.
Open any saved deck and click "Print / PDF." Choose cut-out cards, duplex cards, or a simple list. For duplex, select the correct flip edge (long or short) to match your printer. In the print dialog, select "Save as PDF" to download the file instead of printing.
All your decks are stored locally in your browser using IndexedDB (with a localStorage fallback). Nothing is uploaded to a server. You can back up your entire library as a single JSON file from the dashboard, and export individual decks as CSV anytime.
Your study data is always stored locally and is fully accessible offline. Fonts and the PDF-reading library load from a CDN on first use; if you plan to use the PDF generator offline, load the page once while online first. For a fully offline experience, use your browser's "Install app" or "Add to Home Screen" option.
