Why Avorio
Anki's algorithm pedigree.
Designed for humans.
01 · Import
Your Anki decks, better experience
Import .apkg and .colpkg files with everything intact — ease factors, intervals, review history, media, tags. Anking, Dorian, Lightyear, and AMBOSS-tagged Step decks all open with state preserved.
You don't start over. You level up.
02 · Habit
Learning that feels like a game
Daily streaks with milestone bonuses. Gems you earn by studying and spend on streak freezes and power-ups. Three review modes — Speed Timer, Pomodoro, and Life Drain — so long sessions don't blur together.
Small wins compound into real habits.
03 · Intelligence
AI that stays on your machine
Free tier runs on-device — Ollama on Mac, Apple Intelligence on iPhone/iPad — for explanations and chat, no cloud, no account, no API keys. Paid plans add managed cloud AI across multiple models, including open-source ones, with keys held server-side; you never juggle credentials.
Private by design, not by policy.
04 · Architecture
Offline-first, native on every Apple device
Built in Rust with a SwiftUI front-end. Cards live in a local SQLite database, encrypted by macOS Data Protection / iOS file protection. Sync between your Mac and iPhone is optional, encrypted in transit, and never a requirement.
Your data. Your machine. Your terms.
Algorithm
FSRS-5,
explained without the paper.
A modern spaced-repetition algorithm that learns how your memory actually decays — and schedules cards to land near the retention rate you set.
SM-2
Fixed intervals.
Doubles based on a hand-tuned ease factor. Works, but doesn't adapt to how a card actually behaves for you.
FSRS-5
Curve-fitted to your reviews.
Trains a small forgetting-curve model from your own history, then schedules each card to hit your retention target — 90%, 95%, whatever your boards demand.
Outcome
Fewer reviews, same recall.
On a typical med-school deck, FSRS-5 cuts review load 20–30% versus SM-2 at the same retention. Avorio ships it on by default — no add-ons, no config files.
Meet Avorio
A small elephant
who notices.
A mood for every kind of session. No 11pm push notifications guilt-tripping you. He's there because reviewing 200 cards alone gets bleak — not because dopamine loops convert.
Free + private
Free.
Actually free.
Local-first by default. Cards live on your device, the core review never makes a network call, and accounts are optional. Cloud AI runs through Avorio's managed gateway — paid subscribers get inference without ever holding an API key.
Account optional
Open the app, import a deck, start reviewing. Sign in only when you want sync across devices or cloud AI.
No personal analytics
Zero pixel tracking, zero crash reporters tied to you, zero behavioral analytics. We don't measure things we can't see.
Free core forever
Cards, decks, reviews, .apkg import, local AI on Mac — all free, no card limits. Paid plans only add managed cloud AI.
Local SQLite
Your decks live in a database on your device, encrypted by macOS Data Protection / iOS file protection.
Go further with a paid plan
Bring your own brain.
We'll bring the cloud.
The free core runs on-device — a local LLM on your Mac, Apple Intelligence on iPhone/iPad — no account, no keys, no network call. Basic, Pro, and Max add managed cloud AI through Avorio's gateway: a curated set of open-weight models for generating cards and explaining the hard stuff, with every API key held server-side. You subscribe; we handle the credentials.
Managed cloud AI — no API keys. You never sign up with a provider or paste a key. Keys live on our gateway; you just study.
Open-weight models, routed automatically by task — fast and cheap for flashcards, deeper reasoning for STEM proofs and medical cases. Pick an effort level; we pick the model.
A generous monthly allowance. Pro includes 3 million tokens a month; Max steps up to 12 million (4×) — enough for roughly 1,500 to 6,000 AI card generations.
The free core stays free. Cards, decks, reviews, .apkg import, and on-device AI never cost a thing. A paid plan only adds the cloud.
From $3.99/mo. Three plans — Basic, Pro, and Max — with 1M, 3M, and 12M tokens a month. Cancel anytime.

FAQ
The questions
every Anki user asks.
Yes. Avorio reads .apkg and .colpkg files directly — including ease factors, intervals, lapses, review history, media, tags, and custom note types. Anking, Dorian, Lightyear, AMBOSS-tagged Step decks all open with state intact.
