Home › For Confidential Work

Whatever your profession, if it’s confidential — it stays here.

HR teams handling personnel matters. Consultants under NDA. Journalists protecting sources. Executives with board material. Engineers and founders guarding trade secrets. If your work can’t go to the cloud, SecureOffline runs a capable AI entirely on your Mac — nothing is transmitted, because there is no server.

The problem is the same in every confidential profession

The material that would benefit most from AI — personnel files, source notes, deal documents, agreements, anything under NDA — is exactly the material you can’t paste into a cloud chatbot. Every cloud AI tool means transmitting it to someone else’s servers, logs, and retention policies. So the most sensitive work gets done the slow way, by hand, while everyone else gets the productivity.

SecureOffline removes the transmission, not the usefulness. The AI model runs on your Mac’s own chip. Your documents are read on-device, your drafts are generated on-device, and you can verify with any network monitor that nothing leaves. There is no server to breach, no account, no third-party logs — nothing of your work outside your control.

What confidential work looks like here

Document review & Q&A

Attach agreements, reports, plans, or working files and ask questions — the file is read on your Mac and never uploaded anywhere.

Sensitive drafting

Personnel communications, negotiation emails, memos on matters you can’t discuss outside the building — drafted from your notes, in your voice.

Notes → structure

Turn interview notes, meeting notes, or investigation notes into clean summaries, timelines, and action lists.

Compare & extract

Two versions of an agreement, a stack of statements, a long report — find what changed, what’s missing, what matters.

Copy any result into your own tools with one click, or export a clean PDF. It works on a plane, at a client site, or anywhere else the internet isn’t — or isn’t allowed.

Five prompts to try on day one

Attach the document, ask in plain English. Every one of these runs entirely on your Mac — nothing is uploaded. One honest limit to know: on-device models read a bounded portion of a long attachment — roughly the first 10–15 pages on Personal, nearly double that on Professional — and the app labels the document “partial” whenever that happens, so you always know what the AI saw. Full-document retrieval is next on our roadmap.

“Compare these two versions of the agreement and list every substantive difference between them.”
“Summarize this agreement in one page: who’s committing to what, the deadlines, and anything unusual worth a closer look.”
“Turn my interview notes into a clean, chronological summary with a list of open questions.”
“Draft a firm but courteous response from my bullet points below — professional tone, no filler, under 200 words.”
“Extract every commitment, owner, and deadline from these meeting notes into a checklist.”

Built to be defensible

Private by architecture, not policy. No account, no telemetry, no network calls during use. Verify it yourself with a network monitor.
An accountable vendor. Signed and notarized through Apple’s developer program, published by OnyxLinc LLC, a US company — not an anonymous app store listing.
You stay in control. AI output is a draft for your professional judgment — review before it reaches a client, a colleague, or a file, like anything an assistant hands you.
