There are three ways to get working code in front of you: scaffold a fresh project, read the in-repo reference miniapp, or browse the first-party miniapps that ship in this repo.

​
Start from the scaffolder

The fastest path is create-mentra-miniapp. It writes a ready-to-run project with both layers wired together. The Quickstart walks through it end to end.
It asks for a project name and the kind of glasses you’re targeting. You can skip the prompt with a flag:
The --type choice only changes the manifest’s hardwareRequirements (display vs. camera plus microphone). The generated code is the same either way: a glasses button press calls session.display.render(...), and the WebView UI sends a ping that the background answers with a pong carrying a roundtrip timestamp. That gives you a button-to-display path and a UI-to-background path to edit from.

​
The in-repo reference miniapp

If you’ve cloned the monorepo, miniapps/example-miniapp is the reference app that consumes the SDK. Its manifest names it “Mentra Example”, and it exercises more of the surface than the starter does: transcription, text-wall display, TTS, button events, and an “SDK Tester” UI that drives each session module (session.camera, session.location, notifications, calendar) page by page. Run it from the repo to see the SDK working against your phone:
bun dev validates the manifest, builds both layers, serves them over your LAN, and prints a QR code. Scan it from Mentra App → Settings → Developer settings → Mini App Development → Scan Mini App QR Code (phone and laptop on the same Wi-Fi).

​
First-party miniapps in this repo

These are apps Mentra ships, all under miniapps/. Read them when you want a real feature rather than a demo. Each builds with bun dev the same way the example does.

Teleprompter

miniapps/teleprompter: paste a script and read it off the glasses; scrolling follows your voice or runs at a set speed.

Mentra Maps

miniapps/navigation: turn-by-turn walking navigation with compass heading and Google Maps, driven by session.location.

Recorder

miniapps/recorder: capture the glasses microphone to a WAV file on your phone, play it back, and export it. Built on session.recorder + session.blob.

Captions

miniapps/captions: live transcription rendered on the display, with a WebView for language and display settings.

Translation

miniapps/translation: translate a detected source language into a target language and render it on the display.
New here? Read the Quickstart first, then come back and open whichever app above is closest to what you’re building.
