EverFlip for your AI

List the languages everflip teaches (46+), with code, name, and how many lessons/decks each has. Use to discover what is available before fetching a deck.

Get one language's full structure — its levels and the decks in each (slugs + names + card counts). Use after list_languages to see what a specific language offers before fetching a deck.

Fetch a built-in everflip vocabulary deck by language code and deck slug. Returns the cards (front/back/translation). Use list_languages first to find valid codes and deck slugs.

Compute the next spaced-repetition review with FSRS (the modern algorithm everflip and Anki use). Given an optional prior card state and a rating (1=Again 2=Hard 3=Good 4=Easy), returns the updated state and next due date.

Simulate the FSRS forgetting curve and a spaced-review schedule over time, plus an effort estimate (days to learn N cards). Useful for explaining or planning spaced repetition.

Parse raw flashcard text (CSV, TSV, or an Anki "Notes in Plain Text" export) into clean, structured cards. Handles quoted fields, headers, and the Anki #columns preamble; strips HTML.

Convert a list of cards into an Anki-importable file. Returns both an Anki tab-separated text (with #preamble) and a CSV. Hand the user the content to save and import into Anki.

Turn a list of cards into a shareable everflip study link. Returns a URL that opens straight into the spaced-repetition study flow — no sign-up, no install. The entire deck is encoded in the link itself (nothing is stored on a server), so it works instantly for anyone you give it to. Use this to hand a user a ready-to-study deck of cards you generated.

Build a real Anki .apkg deck file from a list of cards — the file Anki imports in one click (front/back Basic notes). Returns the .apkg as base64; decode it and save as "<name>.apkg". Unlike convert_to_anki (which returns text the user pastes), this is the actual binary package, so there is no manual import mapping. Use when the user wants a ready-to-open Anki deck.

List the certification exams everflip prepares for (e.g. JLPT — the Japanese proficiency test), with their levels and which levels have a live deck set. "JLPT N3 flashcards" is everflip's exam wedge — use this to discover exam prep before fetching an exam deck.

Get one exam's structure — its full name, the subject language it tests, and every level with its readiness (which levels have live everflip decks). Use after list_exams.

Fetch everflip's curated flashcards for a specific exam level, optionally one tier (grammar/vocab/kanji). Returns the cards (front/back/translation) plus the honest coverage meter — how many curated-core cards ship vs. the target. Currently live: JLPT N3. Each card is checked against the level.

Compute a study pace to be ready for an exam by a target date: given the exam date and how many cards are left to master, returns days left, new-cards/day needed (with a mastery buffer so FSRS has time to carry cards to durable recall), and whether a given daily pace is on track.
