Cocovox is packed with features that are easy to overlook. Here are ten things you might not know about.

Voice Mode Works Offline

After the initial setup, Voice Mode can function without an internet connection. The speech recognition engine caches locally, so you can practice vocabulary and pronunciation even when you do not have a signal.

Swipeable Flashcards

Flashcards support swipe gestures. Swipe right if you know the answer, swipe left to review it again. The card stack reshuffles based on your responses, using spaced repetition to prioritize the ones you need to see most.

The Pentagon Blender Has 5 Axes

The pentagon blender in Tone Remix is not just a visual gimmick. Each of the five axes controls an independent dimension of writing tone. Drag the points to blend formality, emotion, complexity, audience awareness, and creative flair into a custom voice.

Adaptive Exercise Difficulty

Deep Dive exercises adapt their difficulty based on your EMA (exponential moving average) mastery score. The system tracks your performance over time and adjusts the challenge level automatically. If you are acing everything, it gets harder. If you are struggling, it provides more scaffolding.

Time-Aware Vocabulary

The CocovoxKeyboard changes its suggested vocabulary based on the time of day. Morning sessions surface different word suggestions than evening ones, reflecting natural patterns in how people communicate at different times.

Four Achievement Rarity Tiers

Achievements come in Common, Rare, Epic, and Legendary tiers. Legendary badges are extremely difficult to earn and require sustained excellence over long periods. Can you collect them all?

Contextual Memory

Your AI tutor remembers context from previous conversations. If you discussed fractions last week and bring up division today, the tutor can reference your earlier work and build on what you already know. This continuity makes the learning experience feel more personal.

Theme-Aware Slideshow Gradients

Slideshow gradient presets automatically adapt to your current theme. Switch from the Velvet theme to Coral and your slideshows update their visual style to match. The presets are designed to look great across all thirteen themes.

Pause and Resume Exercises

You can pause a Deep Dive exercise at any time and come back to it later. Your progress is saved automatically in local storage, so you pick up right where you left off. No need to start over if you get interrupted.

Calendar Sync

The Weekly Planner syncs with external calendars. Connect your Google Calendar, Outlook, or Apple Calendar to see your Cocovox study blocks alongside your other commitments. Changes sync in both directions, so your schedule stays up to date everywhere.
