Dex 101 - Getting started with Dex

Hi believers, we're thrilled to have you here. This guide offers a walkthrough of Dex. All the important things at a glance. Enjoy!

1. Get to know your Dex

Hardware Components

Dex features a front-facing touchscreen and a rear camera. On the side sits a silver power button, while the handle houses two additional buttons for camera and menu.

Power / Sleep

Long-press the silver button to power on, short-press to wake the screen, and long-press again while the device is on to access restart or shutdown options.

Charging

Next to the power button you’ll find a USB-C port and speaker. Use the included USB-C cable and keep Dex lying flat for optimal charging.

Camera

The upper handle button wakes Dex and, on a second tap, launches the camera view so kids can start snapping photos.

Menu / Content Library

The lower handle button exits any active mode—camera, story, or other—and brings up the menu/content library.

2. Activate your Dex with Copilot App

Installing the Copilot app and linking Dex

When Dex is turned on for the first time, a QR code appears on-screen. You scan the code with your phone, which takes you to the Copilot app download page. After installing the app, you grant camera access so it can capture the code again and pair that specific Dex unit with your account.

Creating a parent account

Inside Copilot you choose “Sign in with email,” enter an address, and confirm it via the verification link. Once the email is confirmed, the app returns to the setup flow.

Adding your child’s profile and language goals

You’re prompted to tell Dex what to call your child, enter their birth month and year, choose the language they want to learn, and pick a dialect (Redeem selects Colombian Spanish). You also set the child’s proficiency: “New to the language” keeps most narration in English with introductory Spanish, while “Basic conversations” switches Dex to a full-immersion Spanish mode.

Finishing permissions and first launch

Granting audio-recording permission lets Dex capture the child’s voice for interactive features. Once permissions are accepted, the app finishes syncing and Dex immediately becomes functional. The on-device screen now shows story tiles, which Redeem says will be covered in the next video.

3. Camera + Activities

Camera Mode

Double-press the upper handle button to open the live camera. Take a photo of any object, and Dex immediately describes what it sees in the target language, turning each snapshot into a mini-lesson.

Real-World Language Learning

Every photo becomes a teachable moment: Dex names the object and embeds that new word in full, natural sentences, helping children link vocabulary to tangible items around them.

Flashcard Games

From the main menu, scroll to Animal Flashcards. Each card shows an animal and invites the child to say its name aloud. Tapping the small speaker icon plays the correct pronunciation in the target language first.

Pronunciation Feedback

Dex listens and evaluates. If the pronunciation is too far off it prompts another try; if it’s close enough it counts as correct and moves on, keeping the experience encouraging and game-like. 

Navigation & Exit

At the end of a card set, you can restart or pick a different activity. Press the lower handle button at any point to leave the current mode and return to the home menu.

Updates Coming

Additional games and learning activities will be released over time, so check the menu regularly for new ways to explore with Dex.

4. Interactive Stories

Interactive Stories Overview

Interactive stories sit alongside the other activities on the Dex home-screen. Each tale is voiced in the target language and is tagged by difficulty level. We match the content to your child’s proficiency.

Story Selection

After unlocking the device and entering the menu, scroll through the story tiles. Beginner-friendly titles introduce simple vocabulary and slower narration, while advanced stories use richer sentences and a faster pace.

Beginner Example: “Dex Celebrates Lunar New Year”

This entry-level adventure follows Dex and a friendly elephant celebrating Lunar New Year. At key moments the child chooses what Dex should do next—help decorate at home or explore a city festival—by speaking their choice aloud. Correct responses move the plot forward and reinforce new words tied to holiday customs.

Advanced Example: “Anna and Mia’s Trip to San Francisco”

An upper-level story that assumes greater listening and speaking skills. The child steers the journey through more nuanced voice choices—narration and dialogue remain entirely in the target language, encouraging full-sentence responses.

Voice-Controlled Branching

Every interactive tale presents A/B options the child must answer verbally. Dex evaluates the reply: a clear, correct choice advances the narrative, while an unclear response prompts another attempt. This keeps the experience conversational and playful.

Language Practice Benefit

Because the child actively decides the path, each story supplies repeated opportunities to hear, understand, and speak the target language in context—turning storytelling time into productive language practice.

Navigation & Exit

At any point, pressing the lower handle button returns to the main menu, where you can restart a story or pick a new one. More titles will continue to arrive, so check back regularly for fresh adventures.

5. Insights

Session Review

Each time your child plays on Dex—whether it’s a flash-card round or an interactive story—the entire session appears in the Copilot app. Opening a session shows every word practiced, highlights any terms that still need work, and lists all spoken responses captured during stories.

Progress Tracking

As sessions accumulate, the app builds a timeline of activity so you can watch vocabulary growth over days and weeks. Comparing entries makes it easy to spot strengths, gaps, and overall momentum.

Settings & Wi-Fi

In Settings you can adjust the language level, update profile details, and add a home Wi-Fi network. Dex normally uses its built-in cellular connection, but saving a Wi-Fi name and password provides a steadier link whenever mobile coverage is weak.

Device Management

Tap the initial in the upper corner to see every Dex associated with your account. When your Founding-Edition unit arrives, choose Add Dex, scan its new QR code, and it links instantly. You can then delete the beta unit or switch between multiple devices to view separate insights.

6. Privacy

Philosophy & Beta Notice

Dex is still in beta, and policies or service providers may evolve. Any changes will be clearly communicated so families can decide how their data is handled.

Data Collected

• Child profile: first name or nickname, birth month + year, language level.

• Device/data usage: overall cellular data traffic volume, device name/ID for troubleshooting.

• Parent account: email and password for the Copilot app, plus explicit consent for any additional items not listed above.

Security & Storage

All data is encrypted in transit and stored in Dex Cloud on Amazon Web Services. We default to zero-retention policy for children's media (photo and voice).

Third-Party Sharing

Dex never sells or shares data with brokers or advertisers. Limited, anonymized information may be sent to trusted AI partners (e.g., OpenAI) only when AI features are enabled. Identifiers such as names, emails, and device IDs are stripped, and partners are contractually barred from training their own models on Dex data. We maintain zero-retention agreement with those 3rd providers. 

Device & Content Safety

Dex is a closed system: no browser, app store, or external downloads. All on-device content is pre-reviewed, approved, and tested internally before release.

Managing Your Data

Dex follows COPPA guidelines. Parents can delete all stored data at any time: open the Copilot app → Settings → Delete Account. All associated information is removed within 13-14 days. For additional questions, contact support@camera.com.

7. Troubleshoot + Support

Email Support

If you hit a snag, the quickest route is email. You can write directly to the team’s personal addresses or use the official channel, support@worldexlab.com, which funnels every report into a shared queue so nothing slips through the cracks.

In-App Feedback

Inside the Copilot app, open Settings → Send Feedback and type a note. The message, plus basic diagnostic details, reaches the same support queue and helps the team track patterns across users.

On-Device Beta Menu

Press the two handle buttons simultaneously to open the beta utilities on Dex itself. Tap Troubleshooting to push a log snapshot to the cloud; the team sees the alert automatically.

Need extra details while you’re on a call with support? Choose About Device to read out—or photograph—your device ID, software build, system version, and uptime.

Manual Software Check

Updates normally install in the background, but the beta menu also shows Latest Software. Tap it to force a version check and install any pending patch right away.

Using these three channels—email, in-app feedback, and the on-device beta tools—ensures the team gets the information they need and can turn fixes around quickly.
