Built for people who want to know more, faster

1

Pick your topics and sources

Add YouTube channels, newsletters, publications, Substack, or custom sources. Our AI extracts the signal — implications, not just headlines — from your list. Takes 2 minutes.

2

AI does the filtering and analysis

Every night the AI reads your sources, dedupes stories, identifies emerging trends across sources, and writes a tight 10–30 minute script — in a natural voice, in your timezone.

3

Listen during your morning routine

A crisp MP3 lands in your inbox at the time you chose. Press play on the commute, the dog walk, or while you make coffee. You finish informed — without spending an hour on the feeds yourself.

Provide feedback → improves future intelligence

After every briefing, your feedback shapes the next one. What to lean into, what to skip, what matters to you. Every listen makes the next one smarter — the loop back to step 2 is continuous.

Your AI Editor-in-Chief

You now have your own AI Editor-in-Chief.

It learns what matters, what doesn’t, your interests, your priorities — and continuously improves.

Frequently asked questions

How does personalization work?

You define your subjects and sources. The AI curates, filters, and writes a briefing tailored to your interests — not a generic news roundup.

How does AI learn?

After every briefing, your feedback shapes future ones. The system learns what matters to you, what to skip, and what to prioritize. Every listen makes the next one smarter.

How do I cancel?

Settings → Billing → Cancel subscription. No retention calls, no friction.

How does the trial work?

7 days, free, no credit card. You get the full experience — all topics, all sources, all features.

Why is this different from AI summaries?

Summary tools recap what happened. ListenBrief tells you what it means. It’s closer to a 20-minute briefing from a sharp analyst than a 5-minute news roundup.

How are duplicate stories removed?

Your AI Editor-in-Chief compares every source against historical knowledge. If the same story appears on YouTube, X, news, and blogs, only one survives — with the best angle. You see new insights, not echoes.

How does my personal editor work?

Think of it as your own AI Editor-in-Chief. It learns your interests, your priorities, your industry — and continuously improves. It deduplicates, prioritizes, and writes the briefing you’d write for yourself if you had the time.

In the spirit of

ListenBrief is brand new, so we don’t have a wall of customer reviews yet. What you can read below is the founder’s own framing of why he built it, a friend’s reaction from the early-bird list, and the historical figures we’d brief if we could send a daily podcast back through time. The historical cards are inspirational, not endorsements.

Early reactions

The founder
“To keep myself informed I followed multiple YouTube channels and listened to them when I was driving, in the airplane or walking the dog. The irritating thing was that high profile topics were covered by almost every channel, so I was wasting my time listening to basically the same topic covered by different YouTubers. I still listened because sometimes an interesting extra angle was brought up, but in general I was wasting my time. So when building my dog walk podcast I paid close attention to undubbing stories. And ending with a quote was unbelievably inspiring.”

Rhett, Founder

“Missing your RSS this morning 😝”
