Arty is a desktop tutor for reading, speaking, listening, writing and grammar. Bring your own book, video or API key — nothing is locked behind a subscription.
Five ways to practise, one vocabulary list
READING
Read a real book
Open a PDF or paste text. Tap any word for a definition in context, hear it read aloud, and save it with one click.
SPEAKING
Talk, then get corrected
Hold a spoken conversation on a topic at your level. Afterwards Arty shows what worked and what to fix.
LISTENING
Watch with clickable subtitles
Pull in a YouTube video, follow the subtitles line by line, and look up anything you didn't catch.
WRITING
Write to a brief
Pick a task — a comment, an essay, a report — write a few hundred words, and get line-by-line corrections.
GRAMMAR
Learn a rule, then drill it
Short explanations from A1 to C2, each with examples and an eight-question drill you can repeat.
WORDS
One list, every source
Words saved while reading, watching or talking land in the same list — and come back in quizzes.
AFTER EVERY SESSION
Feedback that names the mistake
Not a score out of five. Arty quotes what you said, writes the corrected version next to it, and explains the rule behind the change — then hands you the words worth keeping.
- Fluency, grammar and vocabulary read separately
- Corrections shown as before / after, with the reason
- New words go straight to your list
No account, ever
There is no sign-up, no profile and no server of ours to hold your progress. You open the app and start.
Your files stay yours
Books, saved words and session history live in a local database on your own machine. Copy it, back it up, delete it.
You pick the model
Arty talks to whichever provider you give it a key for. Pay them cents per session, or point it at a model on your own hardware.
BRING YOUR OWN MATERIAL
The novel you are already reading
Drop in a 900-page PDF and Arty keeps the chapters, your page and your bookmarks. Words you look up are highlighted the next time you meet them, so a re-read shows you what stuck.
Free, and staying free
Arty is a hobby project released under the GPL. No trials, no tiers, no upsell — you pay only whatever your model provider charges you.
