⛨  Notarized by Apple · There is no server

Private AI. Nothing is transmitted.

Advisors, accountants, and mental health professionals can’t paste client data into ChatGPT — or any cloud. SecureOffline runs a capable AI entirely on your Mac, so you can read, summarize, and draft from sensitive documents that never leave your device. Not a privacy promise — an architecture. There is no server to leak.

✓ Client data never leaves your Mac  ·  ✓ No account needed  ·  ✓ 30-day money-back guarantee

Wi-Fi: off — and it works exactly the same. That’s the point.

Built for work that can’t go to the cloud

If your profession makes client confidentiality a legal duty, general AI tools are off-limits for your most sensitive work. SecureOffline is the one you can actually use — because the data never leaves your machine.

One product, one download. The examples differ by profession; the architecture is the same everywhere — your clients’ data never leaves your device. See plans →

A full AI assistant — with nothing leaving your machine

Everything you’d reach for in a cloud AI, running on your own Mac: read your documents, draft on top of them, dictate and listen — on the confidential work you can’t send anywhere.

Reads your documents

Attach statements, returns, case files, or contracts and ask questions about them. The file is read on-device and never uploaded.

Drafts on top of them

Client emails, review summaries, memos, letters — drafted from the documents you provide, in your voice, ready to edit.

Copy & export anywhere

Drop any answer straight into your CRM, email, or Word — copy to clipboard or export a clean PDF. Your workflow, offline.

Dictate & listen

Speak instead of type; hear answers read back. All speech is processed on your Mac — nothing sent to a transcription service.

Private by architecture

Not a policy promise — a design fact. There is no server, no account, no telemetry. Verify it yourself with any network monitor.

An accountable vendor

Signed and notarized by Apple, published by a real US company (OnyxLinc LLC) — not an anonymous app or a weekend Ollama setup.

How it works

Three steps, five minutes, and it’s yours.

Download the app

Apple-notarized for macOS on Apple Silicon (M1 or newer). Open the file, drag to Applications.

Pick your AI model

One-time download, sized to your Mac — from 1 GB (fast) to 5 GB (most capable). Needs internet once.

Go offline. Forever, if you like.

Every answer is generated on your machine. Unplug the router and watch it keep working.

Why not just use ChatGPT, Apple, or a $10 app?

Fair question — we’ll answer it honestly. For casual use, those are fine (and cloud models are smarter online). For confidential client work, the picture changes.

The honest trade-off: online, the big cloud models are smarter. But the sensitive 20% of your work can’t go there — and that’s exactly the work SecureOffline is for. We win where the others aren’t allowed to play.

The same app works when the internet doesn’t

Because it runs entirely on your Mac, SecureOffline keeps working on a plane, in a dead zone, off-grid, or in a blackout — a genuine benefit well beyond the office.

Travelers & remote work

Planes, ships, cabins, dead zones — your AI and your documents come with you.

Questions, answered honestly

Is it safe to use on confidential client data?

That’s the whole reason it exists. SecureOffline makes no network connections during use — the AI model runs on your Mac’s own chip, and your documents, prompts, and answers never leave the device. There’s no server to breach, subpoena, or leak, and nothing to appear in a third party’s logs. You can verify it yourself: run any network monitor while you work and watch for zero traffic. (SecureOffline is a tool you operate under your own professional obligations — it doesn’t make claims of certification on your behalf; it removes the transmission that creates the exposure.)

Isn’t Apple’s built-in AI free — why pay for this?

Apple Intelligence is genuinely good for everyday convenience, and for casual use it may be all you need. But it’s a general OS feature: for harder requests it can route to Apple’s Private Cloud Compute (off-device), it’s tied to your Apple account and OS version, and it isn’t built around a profession’s confidential workflow. SecureOffline is single-purpose: it never leaves the device, works on any Apple-Silicon Mac regardless of OS timeline, reads and drafts from the documents you attach, and comes from an accountable US vendor you can call. Different job.

How is this different from ChatGPT?

ChatGPT runs on OpenAI’s servers: it needs internet and your conversations leave your machine — a non-starter for confidential client work. SecureOffline runs a capable open AI model locally: it works anywhere and nothing is transmitted. Honest trade-off: online, the largest cloud models are smarter. But the sensitive work you can’t send to the cloud is exactly what this is for — try it free and judge on your own documents.

Does it really work with no internet at all?

Yes. After the one-time app and model download, every answer is generated by an AI model running on your Mac’s own chip. Turn off Wi-Fi and it works identically — that’s the product. The only thing that ever needs internet again is downloading a different model or an app update.

What Mac do I need?

Any Apple Silicon Mac (M1 or newer, 2020+) with 8 GB of memory or more. The app recommends the right AI model size for your machine automatically. Intel Macs and an iPad edition are on the roadmap.

Is my data really private?

By architecture, not by promise. There is no server, no account, and no telemetry — the app makes no network connections during use. Don’t take our word for it: run any network monitor (like Little Snitch) while you chat and watch the traffic. Zero packets.

What can it actually do?

General questions and writing, step-by-step guidance for repairs and emergencies, reading and answering questions about your PDFs, voice input, natural spoken answers, and exporting any conversation as a printable PDF. It will honestly say “I’m not sure” rather than guess on safety-critical details.

What’s the refund policy?

30 days, money back, no questions. One number, no contradicting fine print. And the 7-day trial means you’ll know long before you pay.

Who makes this?

SecureOffline.ai is a product of OnyxLinc LLC, a US company. The app is signed and notarized through Apple’s developer program — macOS itself verifies every copy you download. See our trust & verification page for the technical details.
