Kioku pairs SuperMemo-style incremental reading with modern FSRS-6 scheduling. The articles, papers, and notes you read become flashcards you actually retain. Works fully offline. Your collections live in local files you own — never uploaded, always exportable.

Spaced repetition shows a card right before you would forget it.
How well did you recall?
Import any article or PDF, read it in passes, and extract what matters into cards as you go. The rest comes back tomorrow. No pressure to finish in one sitting.
The modern spaced-repetition algorithm schedules every card for the moment just before you would forget it, and retunes itself to your own memory over time.
No account. No cloud. No telemetry unless you opt in. Everything lives in a local file you own, and can export or back up anytime.
Import your .apkg

Paste a URL, drop in a PDF, or bring your Anki decks across.
Highlight as you read and turn passages into cloze and question cards, right in context.

Kioku is built for people who want to own what they learn. It runs fully offline, stores everything locally, and never asks for an account. The ink stays on your paper.
