Changelog

What we've shipped, week by week.

We're building Rival Newsletter as a research project on agentic marketing. This is the public log — every change to how the agents read, write, and personalise.

Improvement

Briefs now know your business

Five context docs — positioning, ICP, pricing, voice, differentiators — capture who you are and what you sell. They're editable from your dashboard and refresh weekly from your live site. Every brief anchors its takeaways to your actual positioning instead of giving you generic advice.

Feature

Drafts you can ship the same day

Every theme in your weekly brief now includes a short ready-to-ship artifact — a tweet, hero line, pricing copy variant — phrased in your voice. Test the draft on Monday afternoon, ship the winner by Wednesday.

Feature

Six signal sources, not just websites

Beyond rival website changes, the agents now read their changelogs, blog posts, web news, Reddit, and Hacker News. Layoffs, fundings, exec moves, content pivots — all surface without you opening another tab.

Improvement

First-week briefs are honest about being first-week

If you just signed up and your rivals haven't moved yet, the brief no longer pretends they have. It introduces each one in present tense — where they stand today — and sets expectations for what changes from next week.

Research

What we're learning, posted in public

We added a research log at /research. Every meaningful thing we discover while building agentic marketing — what works, what surprises us, what we got wrong — gets posted there as we go.

Fix

No more hallucinated competitors in subject lines

The editor agent occasionally invented rivals you weren't tracking. It can't anymore — we reject any subject line that mentions a brand outside your tracked list and fall back to a deterministic version. You'll never open an email about Airtable when you're not tracking Airtable.

Feature

Editable business context in your dashboard

Your dashboard now has five tabs — positioning, ICP, pricing, voice, differentiators — each a markdown doc the agents drafted from your live site. Edit any of them and the agent treats your version as the source of truth from that moment on.

Improvement

Dashboard loads cleanly with proper states

Real loading and error states. The dashboard won't drop to a blank page or a generic 500 if something transient hiccups — you'll always see what's happening and have a way to retry.
