Learning
The Learning tab in Settings controls how translations are shown and what gets saved to study later. Mirrors the in-app Settings → Learning section.
Learning mode
The top toggle decides whether translations appear at all:
- Full — show every translation in the overlay (default).
- Off — capture only, no overlay. Useful when you want to save vocabulary in the background without on-screen distraction.
Overlay placement
The overlay is an always-on-top, transparent, click-through window that sits over your game. You choose where translated text appears:
- Bottom — pinned to the bottom of the screen. Default; works in every translation mode.
- Near text — each translation is drawn right next to the original text, so your eyes barely leave the action. Available in Text Reading and Text Reading + modes (it needs per-line coordinates); Image Recognition falls back to Bottom.
You can also drag the overlay to a custom position with the Set Custom button.
Overlay appearance
Tune the look to your taste:
- Overlay BG — background opacity, 0–100% (default 80%).
- Overlay Font — font size, 12–48 px (default 18 px).
- Highlight — color-code difficult words in the overlay (B2+ orange / red). See Difficulty hints below for the rule.
Difficulty hints (CEFR / JLPT)
When enabled, words in the overlay are tagged by estimated difficulty so you can see at a glance which vocabulary is worth learning:
| Source language | Scale | Visible levels |
|---|---|---|
| Japanese | JLPT | N5 → N1 |
| Other languages | CEFR | A2 → C2 |
Classification uses curated word lists plus length / structure heuristics. Common A1 words are not highlighted to keep the overlay clean.
Auto-save
How aggressively Playto saves what you encounter to your Word Book / Journal:
- Manual — you decide what to save by clicking each word.
- Auto — words above the difficulty threshold are saved automatically as you play.
Auto is convenient for passive sessions; Manual is better when you want a curated study list.
