Learn languages through
the games you love
Playto is a desktop app that reads on-screen text from any PC game with local AI, shows the meaning instantly, and turns gameplay into language immersion. The words you meet collect in a word book — review and quizzes turn them into lasting vocabulary.
It reads the whole game — not just the subtitles
Cursor-follow — hover any menu, tooltip, item or quest text and it reads what's there
Fixed regions — pin a spot and Playto re-reads it the moment the text changes, hands-free
Works on any PC game — Steam or not, with nothing to install into the game
It never interrupts the game — and every word you read can be saved for review, so the game turns into vocabulary you keep.
Reading a game becomes a learning loop
Immersion that sticks: Play → Capture → Save → Review → back to play. Each pass leaves more of the game's vocabulary in your hands.
Play
Run the game like normal. Playto stays out of the way.
Capture
Lines you don't understand land in the Log — original and translation, side by side.
Save
Words and sentences worth keeping go into your study lists.
Review
A few minutes a day in Practice or Session Review locks it in.

Everything you need to learn while you play
From text reading (OCR · Text+ · Image Recognition) to 8 quiz modes and AI-powered tools, Playto turns your gaming time into study time.
Playto supports 12 languages — how fully each feature works can vary by language, and we're expanding coverage. See supported languages →
PLAY & CAPTURE
Reads right on top of your game.
This scene is interactive — hover over any text (tap works too) and flip the controls below. Try both capture modes (cursor follow and fixed region), both reading engines (text reading and image recognition), and overlay placement (over the original, or a subtitle bar at the bottom).

What early players say
It saves the words and sentences you translate so you can study them — flashcards, and clicking a word pulls up a dictionary with example sentences. Because it's built on a game I love, it stays in my head; you keep seeing the frequent words, so the learning effect multiplies. We've reached an era where I can proudly say I'm studying while gaming.
I've always wanted to learn Russian through games because textbooks are too painful. I used to screenshot Genshin storylines, run a free OCR tool (5 screenshots an hour), then type the words into Excel by hand. Playto just lets me skip all those steps — it's already done by the time the game ends.
Amazing use of AI in an area that abuses it. It takes some time to get to know, but it's worth it — and it works perfectly for games from itch.io too!

Common questions
See all FAQ →What is Playto?
Playto is a language-learning tool for PC gamers — not a translator. As you play, it reads the on-screen text with local AI, shows what it means, and saves the words you meet to a personal word book. You review them later with built-in quizzes and spaced repetition, so the more you play, the more your vocabulary grows.
Can you really learn a language just by playing games?
That's the idea behind immersion learning — you pick up a language by understanding real input you care about, not by drilling grammar tables. Playto makes each line comprehensible the moment you meet it, then saves the words so you can lock them in with quizzes and spaced repetition. Playing is the immersion; the review is what makes it stick.
Which games work with Playto?
Any PC game client that displays text. Playto reads your screen and runs as an overlay — no modding, no plugins, no per-game setup. Text-heavy genres work best (JRPGs, visual novels, strategy, simulation). Fast-action games work too; you'll just have fewer words to save per session.
Is it free? How much does it cost?
There's a free edition (Lite) with the core translation workflow, and a one-time paid edition (Standard) that adds cursor-follow capture, all AI engine tiers, all quiz modes, and higher word-book limits. No subscription. See the Steam page for current pricing.
Does it work offline? What does it send over the internet?
Translation runs entirely on your PC — no internet needed while playing. OCR, translation, and all your learning data stay on your machine. Playto doesn't collect your word book, quiz history, or screenshots, and doesn't require an account.
Do I need an NVIDIA GPU?
Local AI works best with an NVIDIA (CUDA) GPU but also supports AMD and Intel GPUs via Vulkan. A CPU-only mode is available but slower. Try the free demo first to confirm it runs well on your hardware before buying.
How is Playto different from a translator like Language Reactor or Textractor?
Those are translation tools — Language Reactor works on video and streaming subtitles, Textractor hooks visual-novel text. Playto is a learning tool for any game client: it reads on-screen text, shows the meaning, and turns the words you meet into a vocabulary you review over time. For a quick translation those tools are fine; for building vocabulary from the games you play, that's what Playto is for.
Can it translate browser games or visual novels?
Browser tabs are intentionally excluded so Playto doesn't translate general web pages. Most visual novels also offer a Steam or downloadable version — install the standalone client and Playto recognizes it as a game and works normally.
