How it works

Local on your Mac. Cloud only if you ask.

Arandu runs entirely on your Mac. Local LLM inference is the default and nothing leaves the machine. If you want frontier-grade reasoning, you can turn on Arandu Cloud — but only after a consent screen that spells out exactly what gets sent, and every call it makes is written to a tamper-evident log you own.

01

Indexed locally

Calendar, mail, contacts, notes, files. Everything stays on disk in a local database on your Mac. We never touch your data over the network.

02

Cloud is opt-in, and it asks first

Local inference is the default: nothing leaves your Mac at all. Turning on Arandu Cloud takes an explicit, one-time consent screen that says plainly what goes out — your conversation, including the personal context Arandu has learned. No dark pattern, no buried toggle.

Every call on the record

Each cloud request is appended to a SHA-256-chained audit log on your machine — which model, when, how many tokens. The chain is tamper-evident: break a link and verification fails. Read it and verify it yourself, any time, in the app.

What it does

A second mind that earns your trust.

Not a chatbot. Not a productivity dashboard. A continuously running personal AI that learns your life and quietly keeps it organized.

Daily brief

A morning summary in your language. People mentioned, money discussed, dates coming up, threads needing a reply.

Unified inbox

Threads, tasks, and habits collapsed into one ranked stream sorted by what matters most today.

Goal-aware

Pin a horizon ("schedule volleyball reservations"), pin a why ("regular sports + social"). Arandu links every task to a goal.

Composable agents

Write your own — schedules, prompts, delivery to WhatsApp / email / push. Or use the 33 system agents that ship with the app.

15+ connectors

Calendar, Mail, Contacts, Files, WhatsApp, Notion, Linear, Jira, Strava, Oura — all indexed locally on first sync.

Auditable everything

Every firewall decision and every cloud call — cryptographically chained. Verify the chain anytime in Settings.

Security

Local by default. Auditable when it isn't.

Privacy isn't a checkbox on a page. It's a chain of design decisions you can inspect — in source code we publish under Apache 2.0.

What we guarantee

  • No telemetry by default. The app is silent until you explicitly opt in.
  • Local inference sends nothing. Stay on a local model and there is no egress path at all — not reduced, not redacted. None.
  • Cloud asks before it's ever used. A one-time consent screen states plainly that your conversation and learned context are what get sent. Decline and you stay local.
  • Every cloud call is logged locally. Tamper-evident SHA-256 chain, verifiable in the app — so "what left my machine, and when" is a question you can answer yourself.
  • Open source. Apache 2.0. The whole local app — firewall, agents, connectors, storage — is on GitHub to audit. The cloud and billing layer is closed.
Pricing

Simple, honest pricing.

Pay only for what you use. Local LLM inference is free. Cloud LLM inference is billed per token — $10 minimum top-up. Earn $5 in credits for every friend you refer.

FAQ

Questions, honestly answered.

What is Arandu vs Arandu Pro?
Arandu is the open-source app: clone it, build it, run it with local LLM inference only. It has no code that talks to any cloud — there is nothing to opt into. Arandu Pro is the packaged build that adds one thing: the option to route prompts to Arandu Cloud when a local model isn't enough. Same app underneath, plus an off-by-default cloud switch and the billing to go with it.
How does billing work?
$1.00 per million tokens in, $5.00 per million tokens out — the same rate on every model, no tiers to choose between. Reading costs less than writing, which is how the underlying providers price it too. A typical daily brief is ~20k in + ~5k out (~$0.05). A complex multi-step reasoning answer, ~85k in + ~15k out (~$0.16). You top up in $10 / $25 / $100 packs ($10 minimum). Earn $5 in credits per referral. If you run out, the app pauses cloud calls and falls back to local inference — no auto-charge.
What actually gets sent when I turn on cloud mode?
Your conversation, as-is — including the personal context Arandu has assembled to answer well: names, schedules, message content, whatever the question needs. We don't pretend otherwise. An earlier version of this app tried to strip names and amounts out before sending, and we removed it: it degraded answers badly (a brief about redacted people is a brief about nobody) while doing little for privacy, since the surrounding text went anyway. So the honest deal is the one on the consent screen — cloud mode sends your conversation, it's off until you turn it on, every call is logged locally, and you can go back to local-only at any time. If you never want that trade, run local inference or build the open-source Arandu app, which has no cloud path at all.
Who runs the LLM inference for Arandu Cloud?
Arandu Cloud is our gateway, running on infrastructure we operate, in front of a third-party model provider we select and can rotate as better models ship. Our own gateway keeps no conversation content — it proxies the request and streams the answer back, storing only token counts for billing. The upstream provider's handling of a request is governed by that provider's policy, not ours, which is exactly why cloud mode is opt-in and logged rather than sold as a privacy feature. Want none of it? Stay local.
Is Arandu available on iPhone / iPad?
Companion iOS app is on the roadmap. It will read from your Mac's local index over end-to-end-encrypted sync — never directly from cloud connectors. Beta opens late 2026.
How is this different from Apple Intelligence or ChatGPT?
Apple Intelligence only sees data inside Apple's own apps. ChatGPT sees only what you paste into it. Arandu runs continuously, indexes your whole digital life on disk, and gives every prompt full context — with you deciding whether that runs on your own machine or, if you opt in, in our cloud.
What if I stop topping up?
There's nothing to cancel — Arandu Pro is pay-as-you-go. When your balance hits $0, cloud calls pause and the app falls back to local LLM inference. Nothing auto-charges. Your data stays on your Mac. Top up again any time.
Is Arandu open source?
The local app is, under Apache 2.0 — firewall, agents, connectors, storage, the whole thing, at github.com/vdittgen/arandu. Build it yourself and you get a fully local assistant with no cloud path in the codebase. What's closed is the Pro overlay: the cloud gateway, the account and billing service, and the client code that talks to them. We'd rather say that plainly than claim "fully open source" and hope nobody checks.
