Aside is a private, on-device AI chat app for iPhone — powered by Apple Intelligence, no servers, no account, works in airplane mode. Five Apple Intelligence demos baked in. Free on the App Store; full Xcode source as a one-time $19 purchase.
Payments are handled by Polar, our merchant of record. Polar issues your receipt/invoice and manages the download — so everything about a purchase lives in the Polar customer portal:
Enter the email you used at checkout; Polar emails you a one-time link. From the portal you can:
Your purchase doesn't expire — sign in to the portal any time to download the latest delivered zip. Newer revisions (e.g. when a new App Store version ships) get added to the same benefit, so re-downloading always gets you the latest.
The order-confirmation email from Polar is your receipt. A formal invoice (with your billing details, VAT/tax where applicable) can be downloaded from the order in the portal. Because Polar is the merchant of record, any tax is handled there.
The portal lists all your orders and benefits. The source bundle is a one-time purchase — there's no subscription to cancel.
I didn't get any email after paying. Check the spam folder and confirm which address you entered at checkout — the email goes there, not necessarily your main inbox. You can always access the download via the customer portal.
What's included? The complete Xcode project (xcodegen project.yml + all Swift source), the five Apple Intelligence demos (Image Playground, Writing Tools, Translate, Summarize, Smart Reply), the FoundationModels wrapper, SwiftData persistence, the on-device voice input, and a customer-facing AGENTS.md. ~2.3 MB.
Can I use it commercially? Yes — the license covers personal and commercial use. Build derivatives, change branding, ship under your own developer account.
How do I build it? brew install xcodegen → xcodegen generate → open Solo.xcodeproj → set your team in Signing → change com.example.aside to your own bundle id → run on iOS 26+ (Apple Intelligence required).
Refunds? There's a 7-day money-back guarantee — reply to your Polar receipt email within 7 days. Polar (merchant of record) processes the refund.
iPhone 15 Pro or later, running iOS 26 or newer. Apple Intelligence is required because the entire chat runs on it — there's no cloud fallback.
Locally on your iPhone, in Aside's app sandbox via SwiftData. Nothing leaves the device. If you have iCloud Backup enabled, your encrypted device backup will include the chat database — that's between you and Apple.
Apple Intelligence loads the on-device model on the first prompt of a session. Subsequent replies in the same session are noticeably faster. The model itself ships with iOS — no download needed.
Yes, entirely. Aside makes zero network calls. Toggle Airplane Mode and the chat continues working.
Settings → Persona. Choose from presets or write your own system prompt. The new persona applies on the next message.
Microphone button → speak → tap Send. Transcription runs on-device via Apple's Speech framework. You can optionally enable Auto-send in Settings.

For purchase issues (refund, re-download, invoice), use the Polar customer portal with the email you used at checkout.
See the Privacy Policy. Short version: Aside collects nothing — the chat runs entirely on your device, all data stays local.
