What are you learning?

Each language is a separate course with its own deck, review history and daily budget. You can switch any time, and add another later.

Lessons

Each lesson teaches one thing and takes about twenty minutes. They're written against your actual diagnosis, so the order matters — work through them in sequence. Opens in a new tab; this one keeps your place.

Reference sheets

The compressed version, built for looking things up rather than reading through. Prints cleanly — worth keeping one next to your editor.

Add a word

Type a word and look it up — the definition, part of speech, phonetics and synonyms come from Wiktionary, and if it has no example sentence one is pulled from the Tatoeba corpus instead. Everything stays editable before you save.

Import a spreadsheet

Excel (.xlsx), CSV or TSV. Columns are matched by their header names where possible and you can correct the mapping before anything is added. A word and a definition are required; everything else is optional.

Your words

Daily new words

How many unseen words enter the rotation each day. Lower it if reviews pile up.

Pronunciation

Press P on any card, or the speaker button. Human recordings are used when Wiktionary has one for that word; everything else — phrasal verbs, idioms, anything multi-word — falls back to your browser's built-in speech synthesis, so all 500 entries can be heard. This setting is per device, since available voices depend on the OS.

Your account

Each account has its own deck, review history and added words — nobody else can see them. Reviewing itself never waits on the network: everything saves locally first and syncs in the background, so a dropped connection mid-session costs you nothing.

Backup

Works with or without sync. A file export is the only copy that survives losing your sync code, so it's still worth doing occasionally.

How the scheduling works

Cards are scheduled with SM-2, the SuperMemo algorithm that Anki's scheduler grew out of. Each card carries an easiness factor starting at 2.50. Recall it well and the gap to the next review multiplies by that factor; fail it and the card resets to one day and the factor drops (floor 1.30). First two successful intervals are fixed at 1 day and 6 days. Original spec ↗
