# Guides for building apps with AI | NorthernGo > Tested guides for building real web apps with AI: local generation on your own GPU, Supabase data, Stripe payments, offline PWAs and GDPR. Source: https://northerngo.com/resources/ Language: en Updated: 2026-08-28 --- Step-by-step guides for building and shipping real web apps with AI — from local generation on your own GPU to databases, payments, offline support and code ownership. Every guide documents what does not work as clearly as what does. ## Backend & Database - [How to store data in an AI-built app with Supabase](https://northerngo.com/resources/connect-supabase/): Every app built in NorthernGo gets a Supabase PostgreSQL database automatically. Here is the exact API for saving, reading and deleting records, plus how to add per-user login. ## Next-Gen AI & WebGPU - [How local AI works in the browser with WebGPU and React](https://northerngo.com/resources/webgpu-react-local-ai/): NorthernGo runs language models on your own graphics card through WebGPU. What actually runs locally, which five models you can choose, and where it fails. ## Cloud & Hosting - [How to publish an AI-built app and get a live URL](https://northerngo.com/resources/cloud-deployment-firebase-hosting/): There is no deploy step in NorthernGo: saving a project is what puts it online. How apps are stored, which URL each plan gets, and what goes wrong. ## Domains & Security - [How to connect your own domain to an AI-built app](https://northerngo.com/resources/connect-custom-domain-ssl/): Connecting a domain needs Pro, a matching subdomain name and one CNAME record. What the platform configures for you, and why the first label matters. ## PWA & Mobile Optimization - [How to turn an AI-built app into an installable PWA with your own icon](https://northerngo.com/resources/create-pwa-app-icons/): Publish an app built in NorthernGo to its own .northerngo.com subdomain, upload a square icon, and install it on the home screen on both iOS and Android. ## SaaS Monetization - [How to accept payments in an AI-built app with your own Stripe keys](https://northerngo.com/resources/integrate-stripe-payments-saas/): Connect your own Stripe key to an app built in NorthernGo, open a Checkout session that takes card and Klarna, and see exactly who is responsible for what. ## Native App Development - [How to export an AI-built app as a native iOS and Android project with Capacitor](https://northerngo.com/resources/export-native-ios-android-capacitor/): Download your NorthernGo app as a Capacitor-ready ZIP, add the iOS and Android platforms, and open it in Xcode or Android Studio — plus what is missing. ## AI Features & Travel - [How to build an AI travel assistant that recommends real places](https://northerngo.com/resources/ai-travel-assistant-concierge/): A travel concierge app is a place database plus one AI call that picks from it. Here is the code, the plan requirement, and how to stop it inventing places. ## E-commerce & Monetization - [How to build a single-product store on top of Shopify with AI](https://northerngo.com/resources/trending-ecommerce-sleep-wellness/): Build a storefront that fetches products from your own Shopify and hands the cart to Shopify checkout. The exact API, the Pro requirement and the real limits. ## Offline & PWA - [How to build a web app that still works without internet](https://northerngo.com/resources/offline-first-web-apps-pwa/): Most web apps show a blank screen in airplane mode. Here is how a service worker keeps your app loading and usable offline — and which parts genuinely cannot work without a connection. ## Local AI & Privacy - [Local AI vs cloud AI app builders: cost, privacy and speed](https://northerngo.com/resources/local-ai-vs-cloud-ai-app-builders/): Cloud AI builders bill per generation and send your prompts to a third party.

Includes the exact CORS commands for macOS, Linux and Windows that most guides leave out. - [A vibe coding platform that still owns the unread code](https://northerngo.com/resources/vibe-coding-platform/): Vibe coding is describing software and accepting the result. A platform around that loop still leaves you liable for unread code. Here is the honest version. ## GDPR & Compliance - [Building GDPR-compliant apps: a practical checklist for EU founders](https://northerngo.com/resources/gdpr-compliant-app-building-eu/): A practical checklist for EU founders building apps that handle personal data: consent, data location, deletion rights and what AI generation adds to the picture.
