1. Adaptive Proficiency Re-Writing

The Sidekick doesn't just translate text: it re-shapes it. It analyzes the page and rewrites the Spanish side of your split-screen to match your exact proficiency level. It provides the "scaffolding" you need to enjoy the story while subtly pushing you toward the next level of fluency.

And you're never guessing where you stand: the Sidekick labels the difficulty of each paragraph, so you can see at a glance which passages are comfortable and which are stretching you. This is comprehensible input you can actually see working.

2. Real-Time Vocabulary & Phrase Capture
Forget manual flashcards. As you read what you love, the Sidekick acts as a silent partner. Find a word you don't know? A single click sends it straight to your LinguaVault word bank.

The capability extends beyond isolated words: the Sidekick automatically picks out useful phrases from each paragraph. One click lets you add whole contextual chunks to your deck, helping you build the expressions real conversation is actually made of. Because you met them in a story you enjoyed, they're already far more likely to stick.

3. Paragraph-Level Comprehension Quizzes
Recall is where the learning actually happens. At the end of every paragraph, hit the "Quiz Me" button. These aren’t generic tests: they are context-aware challenges designed to ensure your brain is actively processing the new language instead of just skimming.

• Interest-Driven Encoding: When you read content you actually care about, you engage with it more deeply. Attention and personal relevance are the strongest biological drivers of what your brain encodes and retains over the long term.
• The Push-Pull Dynamic: This approach is rooted directly in comprehensible input theory. Keeping the adapted web text just at the edge of your current ability eliminates the cognitive frustration of text that is too hard (the pull) while maximizing your overall rate of language acquisition (the push).
• Zero-Friction Immersion: By modifying the text directly on the page, the Sidekick lets you stay fully immersed in your reading material. You can build your vocabulary naturally in context, without breaking your momentum to toggle between browser tabs and dictionary apps.
