We make newsletters better.

Personalized for every reader. Smarter with every send. Real relationships at scale.

Riff is the newsletter platform that understands your audience β€” so every reader gets the version meant for them.

This is a newsletter.

You write it once. Everyone gets the same thing.

Now imagine it knows each reader.

Same voice. Different conversation.

Rachel β€” just starting to explore wine
David β€” serious collector, 600+ bottles

Readers reply. The AI listens.

Every reply makes the next issue smarter.

ok I love this but β€” two bottles on a weeknight? I can't finish two bottles. Also I don't know what to pair. I just buy whatever has a cool label honestly

Ha β€” you don't finish them. You open both, pour a glass of each, and compare. Cork the rest. They'll be fine for 2-3 days.

On the label thing β€” no judgment, everyone starts there. But try this: next time you're at the shop, grab one bottle you'd normally pick AND one from the same region that looks boring. The boring-looking bottle is usually the one made by someone who spent money on wine instead of graphic design.

What's your price range? I can give you three specific bottles to try this week.

Like $15-25 usually. Sometimes $30 if I'm feeling fancy

Next week, their newsletters diverge.

Same writer. Completely different issues.

Rachel's next issue
David's next issue

That's a riff.

One writer. Thousands of readers.
Every single one gets their own version.

Works for wine writers, fitness coaches, VCs, teachers, local businesses, anyone with an audience and something to say.
