How we're different
The big AI dailies — The Rundown, TLDR, Superhuman — are excellent at broad coverage for millions of readers. ContentBuffer is deliberately smaller: fewer, higher-signal items chosen for people who build, with every story linked to its source. And unlike email-only newsletters, everything lives on a browsable site you can search and share. See how we compare →
Frequently asked questions
Is ContentBuffer free?
Yes — entirely free. The daily email, the weekly vertical newsletters, and everything on the site. It is supported by clearly-labeled sponsorships, never paywalls.
When does the newsletter arrive?
Every morning at about 7am Pacific Time, timed to local mornings for readers in other timezones.
How long does it take to read?
About 5 minutes. We deliberately pick fewer, higher-signal stories instead of long link dumps.
How is ContentBuffer different from TLDR or The Rundown?
The mega-dailies are excellent but broad, and they are email-only. ContentBuffer is smaller and more curated, and pairs the email with a live site: an AI tools directory, guides, a jobs board, and an hourly-updated news feed.
Who writes ContentBuffer?
ContentBuffer is independently published by Kodetra Technologies. Stories are curated editorially with AI-assisted summarization, and every item links to its original source.
How do I unsubscribe?
One click on the unsubscribe link in the footer of any email. No account or confirmation hoops.
What are the vertical newsletters?
Optional weekly digests on Quantum computing, Robotics, and general Tech — subscribe to any of them independently of the daily AI letter.
