Dictionary & Word Book

Look up any word with AI-generated definitions, save it to your personal vocabulary, and track mastery over time.

Word Lookup

Click any word in the translation log or overlay to trigger an AI-powered dictionary lookup. The LLM generates a context-aware definition that includes:

  • Primary meaning in context
  • Alternative meanings
  • Part of speech
  • Example usage from the game

Definitions are generated by the same LLM used for translation, so they understand game-specific terminology and context.

Word Book

Save looked-up words to your Word Book for later review. Each entry stores:

  • The word and its definition
  • The original context (sentence where you found it)
  • The game profile it came from
  • Timestamp and language pair
  • Mastery tracking (correct/wrong counts from quizzes)

Free version: Up to 50 words (cumulative). Pro: Unlimited.

Spaced Repetition (SRS)

Words are tracked with a mastery system based on quiz performance:

  • New — never quizzed
  • Learning — quizzed but not yet mastered
  • Mastered — 3+ correct answers with more correct than wrong

The mastery bar at the top of the Word Book shows your progress at a glance. Quiz modes draw from your Word Book with SRS scheduling to prioritize words you need to practice most.

Editing & Regeneration

Manual editing: Click any word entry to edit its definition in the detail panel. Useful for correcting AI definitions or adding personal notes.

AI regeneration: Request a fresh AI-generated definition if the original wasn't accurate. The LLM re-generates using the stored context.

Blacklist

When auto-save is enabled, Playto automatically saves words it encounters during gameplay. The blacklist lets you exclude specific words from auto-saving — useful for proper nouns, game UI labels, or words you already know well.

Blacklists are per Game Pack, so different games can have different exclusion lists.

Auto-Save

Playto can automatically extract and save words from translated text. Three modes:

  • Manual — only save words you explicitly click
  • Quality — auto-save from refined/VLM translations only
  • All — auto-save from every translation

Auto-save filters out stop words (common function words), short words (<4 characters), and blacklisted words.
