Chat with AI
that never leaves
your iPhone.
Aside runs entirely on-device using Apple Intelligence. No servers. No cloud. No account. Works in airplane mode. Your conversations stay where they started.
$9.99 on the App Store · Free in TestFlight beta · iPhone 15 Pro or later · iOS 26+
Built for the conversations that matter
Aside is for the questions you wouldn't post to a server. Health. Legal. Personal. Drafts you're not ready to share. Aside answers — and forgets nothing, because it never had a reason to remember anywhere but on your phone.
100% on-device
Your conversations stay on your iPhone.
Aside speaks to Apple Intelligence directly on your phone's Neural Engine. There's no server it could send your messages to. No cloud sync. No account to leak. Verify with a packet sniffer — Aside makes zero outbound network requests during a chat.
Code, Markdown, formatting
Polished replies — even on a plane.
Code blocks render in monospace inside framed boxes. Markdown headings and bold come through cleanly. Long-press any message to copy, regenerate, or delete. Because everything is local, you get this even at 35,000 feet.
History + search + export
Every chat saves on-device.
Organized in a clean list, sorted by recency. Pull down to search across every message you've ever written. Open any chat's menu to share or copy it as Markdown. Delete in a swipe.
Make it yours
Personality, look, and feel.
Pick a persona (concise, friendly tutor, brutally honest, code-focused — or write your own). Adjust text size, toggle Markdown rendering or the suggested-prompt chips, turn haptics on or off. Aside adapts to how you actually use it.
Why an on-device chat?
Most AI chat apps ship your conversation to a server and call it "private" because they encrypt the transport. Aside takes a different shape: the model itself lives on your phone, and the conversation never has the option of leaving.
No account
Nothing to sign up for. Install, open, chat. There's no profile, no login, no email.
No telemetry
Aside makes zero outbound network requests during a chat. Verify with any network monitor.
No cloud
Everything — conversations, attached photos, your settings — stays on the iPhone.
Common questions
Which iPhones support Aside?
Any iPhone that supports Apple Intelligence — iPhone 15 Pro / Pro Max, and all iPhone 16 / 17 models. You'll need iOS 26 or later and Apple Intelligence enabled in Settings.
Is Aside really free of any cloud?
Yes. Aside uses Apple's FoundationModels framework, which runs the language model on your device's Neural Engine. There's no API key, no remote inference, no fallback to a cloud LLM. If your phone is in airplane mode, Aside still works.
Why an on-device LLM instead of GPT-4 or Claude?
Different trade-off. Frontier cloud models are smarter; on-device models are private. Aside is for the moments where the conversation actually matters — health questions, legal drafts, journaling, exploring an idea — and you don't want it on someone else's server.
Will Aside ever add cloud features?
No. The whole point is "this conversation never leaves your phone." If we ever ship cloud sync or remote inference, it'll be a separate app — Aside stays local-only.
Can I attach photos?
Yes. Aside uses on-device Vision to extract text and classify the image, then asks the on-device model to reason about it. The image and its analysis never leave your phone.
Can I export a conversation?
Open the chat's menu (⋯) and pick "Share conversation" or "Copy as Markdown". You get a clean Markdown transcript you can paste anywhere.
How much does Aside cost?
$9.99 one-time on the App Store. No subscription, no in-app purchase, no upsell. Free during the TestFlight beta if you want to try it first.
Can I buy the source code?
Yes — Aside's complete iOS Swift source is available as a one-time $19 bundle, designed to be AI-agent friendly (well-commented, AGENTS.md included). Same package the app ships from. Coming soon on Polar.
Install it. Forget about it. Talk to it whenever.
