The mail we answer fastest

Scheduler discrepancies. If a card’s interval doesn’t match the documented algorithm, that’s a bug and we want it: tell us the card’s grade history (or attach the exported CSV) and what interval you expected.

Import/export problems. A CSV that imports wrong, an export that a spreadsheet can’t read, an Anki round-trip that loses cards. Attaching the actual file (or the first dozen lines) turns a week of guessing into a same-day fix.

Sample-deck corrections. Vocabulary and capitals should be boringly correct. If a card in the Spanish or capitals sample decks is wrong, awkward, or out of date, name the card.

Also welcome

• Feature requests — within the site’s single-job scope: scheduling, decks, CSV, session flow.
• Accessibility issues — keyboard traps, contrast problems, screen-reader weirdness.
• Everything else — broken pages, typos, partnership requests.

Include the page URL and, for app problems, your browser and OS. Since your decks live in your browser, we can’t see them — the exported CSV is the fastest way to show us what you’re seeing.

Response expectations

A person reads every message; there is no ticket queue. Bug reports and corrections usually get a reply within a few days. If your report becomes a fix, you’ll see it land rather than get a changelog — small site, direct line.
