A real assistant on your iPhone — chat, browse, remember, automate. Bring your own keys, run a model on-device, or pair with the aricode desktop over end-to-end encryption. No accounts, no analytics, no middleman between you and the model.
The biggest mode. Bring your own keys, run a local GGUF, or both. Personas with their own memory, routines, watchers, briefings, native iOS tools, and a real browser with Ari sitting beside the page you're on.
Scan one QR code to pair with aricode on your Mac. Stream long-running jobs, approve tool calls, and glance at what your workstation is doing without touching it.
Named agents live on your Mac — each with a persona, a pinned workspace, and its own browser profile. Chat them like people from the phone; they read mail, browse, file things, draft replies. Anything outside the pin routes to you for a tap.
On-device GGUF inference is a real fallback for privacy moments and offline use, but for day-to-day Ari you want a frontier model with full tool support, fast streaming, and a context window that fits a real browse session. Two we recommend:
gpt-5.4-mini as Ari's daily driver — cheap, fast, full tool support. Step up to gpt-5.5 for the harder turns, or gpt-5.4-nano for the absolute cheapest path. Pay-as-you-go; a $5 top-up lasts weeks of casual chat.
Subscription, billed on GPU time not per-token — Pro is $20/month. Generous quotas covering frontier open models. Daily drivers: deepseek-v4-flash, qwen3-next, gemma4. Frontier picks for harder turns: deepseek-v4-pro, kimi-k2.6, minimax-m2.7, glm-5.1.
https://ollama.comWant offline? Drop a GGUF into Files → AriCore → Models. No key needed, runs entirely on the phone — just slower and with smaller models.
Threads, memories, personas, notes, canvases and study courses now travel with your iCloud account. Open AriCore on a second iPhone, an iPad, or your Mac and your full state arrives a few seconds later. Apple operates the infrastructure through your private CloudKit container — we have no access to any of it.
A community gallery of plugins (ONE-mode JS extensions), skills (tools Ari can call) and personas (full assistant configurations) shared between AriCore users. Opt-in to publish, opt-in to install. Every download shows you the full source before it touches your assistant.
Personas finally gets its own bottom-bar tab in Solo — between Study and Browse — so switching between your work, home and research personas is one tap instead of three. The old Settings route still works if you prefer the long way.
A real browser inside the app — tabs, bookmarks, history, reader mode, private tabs, ad blocking. A floating Ari orb sits in the corner of the page; tap it and the chat slides up. Ask Ari to summarise, extract, or act on the page in front of you.
Ask Ari to add something to a basket, log into a site, file a contact form. It scouts the page, plans every step, and shows you the whole batch on a single approval card before anything fires. Each action highlights the element it's about to touch — you see exactly what's happening.
A "work" persona that knows your colleagues; a "home" persona that knows the dog's vet; a "research" persona that's read everything you've saved. Each one has its own system prompt, memory bank, default model, and tool allowlist. Switch between them with a tap.
Calendar events, Reminders, Mail drafts, iMessages, Shortcuts. Every tool routes through native iOS APIs — events appear in the system Calendar, drafts open in Mail, reminders are real EKReminders. Approval cards show the exact payload before each call fires.
Set a routine that fires every morning, weekday, or specific weekday. Ari writes you a briefing — calendar, weather, reminders, news if you've configured it — and posts it as a fresh thread you can read with coffee. Watchers do the same on event triggers (location, calendar, weather changes).
An optional cosmetic. Sun by day, moon by night, with a soft crossfade through dusk and dawn. Cloud outlines drift across the masthead in fair weather; rain, snow, fog, or thunder show up when the forecast says so. A starfield with the rare shooting star at night.
Paper is the original — warm cream, ink-black type, one gold accent. Midnight matches the website's dark "Golden Thread" aesthetic — deep ink with brass accents. Both ship with the app, both included in Solar Hours' day-arc.
Slate — cool blue-grey newsroom calm. Vellum — pinks and clays, the art-journal palette. Ink — black on paper, all restraint. Three quieter palettes for users who want neutral chrome without the warm cream.
Linotype — cornflower / press-blue, hot-metal type. Foxglove — saturated lilac with magenta-purple, deep bloom. Verdigris — jade and tropical teal, glasshouse rooms. Crow — brick-blood with white and black, cinema poster. Manuscript — honey amber with aubergine purpura, illuminated.
Warm cream, ink-black type, one gold accent. The interface gets out of the way so the model's output doesn't have to fight for attention.






AriCore has no accounts, no analytics, no crash reporting that phones home. Messages between phone and desktop are end-to-end encrypted with standard primitives — the relay server only ever sees ciphertext.
X25519 ephemeral key exchange. A short fingerprint is compared on both screens before anything is trusted.
ChaCha20-Poly1305 AEAD on every frame. Keys derived with HKDF-SHA256, fresh per session.
API keys and device keypair live in the iOS Keychain with ThisDeviceOnly access. No iCloud sync, no backup leak.
A chat app that doesn't watch you chat.
That's the whole pitch.
