What's in it

More than 2,200 briefs, and a new one most days.

Enterprise AI

Deployments, agents, infrastructure, and what companies are actually shipping.

Fintech & payments

Banking, digital payments, stablecoins and tokenized assets.

AI research & models

New papers, open-source releases, LLM and agentic AI developments.

Policy & regulation

AI governance, risk and compliance, and how the rules are changing.

Investment & startups

Funding, venture activity, and the deals behind the headlines.

US, China & Singapore

Regional coverage of the places where this is being decided.

Listen on the way in

Any brief can be spoken aloud, with a voice you choose per language and a speed you set. Playback keeps going with the screen off and the phone in your pocket, and a mini player follows you around the app. A commute is enough for a day's briefing.

Works with no signal

The newest issues and everything you've saved are downloaded before you open them — not fetched at the moment you need them. The archive still reads on a plane, or underground.

An archive you can actually search

Thousands of past briefs, searchable in English and Chinese, browsable by tag, and indexed in Spotlight — so you can find the one you half-remember from the Home Screen without opening the app.

On the Home Screen, and in Siri

A Home Screen and Lock Screen widget shows the newest issues. Ask Siri to play today's briefs or open the latest one, or build either into a shortcut of your own.

Quiet by default

Refresh manually or on an interval you choose. Notifications are off until you ask for them, and there is no badge counting unread issues at you.

Reads in English and Chinese

The whole app, not just the briefs: 中文界面, Chinese voices for listening, and search that handles both.

No account. No tracking. No subscription.

Deltabrief has no sign-up, no analytics, no advertising and no third-party SDKs. What you read, what you save and how you set it up never leaves your iPhone. One purchase, and that's the transaction.
