Built for the people who write, edit, and grow newsletters
The problem
Most newsletters fail for the same five reasons
Creators rarely lack ideas. What they lack is a clear, honest read on what's actually working — and what to do next.
- What's weak in this draft, specifically
- What's repetitive across issues
- What's quietly hurting engagement
- What should be rewritten before it ships
- What readers actually value, versus what feels good to write
Newsletter Engine AI answers all five — before you hit publish.
Platform
An editorial team, built into your workflow
Ten capabilities that turn every newsletter into a chance to get sharper.
Editorial Intelligence™
Analyzes every newsletter like a professional editor would — structure, voice, originality, flow, and eight more dimensions, scored and explained.
Editorial DNA™
Captures your unique writing style — sentence rhythm, tone, vocabulary, and the habits that make your voice recognizable.
Living Writer Brain™
A structured, versioned model of your writing that keeps learning from every piece you approve — not a static style guide.
Editorial Coaching™
Specific, actionable recommendations for this draft — not generic advice, but what to fix and why it matters.
Generate V2™
One-click rewrite that applies every improvement recommendation at once, then re-analyzes the result against the original.
Editorial Strategy™
Tracks topic coverage, saturation, and gaps across your archive so you know exactly what to publish next.
Knowledge Sources™
Train your Writer Brain on PDFs, books, transcripts, and videos — the material behind your voice, not just your published output.
Research Intelligence™
Strengthens every article with better evidence — surfacing missing citations and validating factual claims.
Sessions™
Every version, every analysis, every rewrite — tracked in one place, so you can see exactly how a draft evolved.
Export
Premium PDF reports and clean Markdown exports, ready to share with a team or drop straight into your publishing tool.

Why it's different
Not another AI writer
General-purpose AI generates text. Newsletter Engine AI builds an editorial understanding of your work that compounds over time.
| Traditional AI | Newsletter Engine AI | |
|---|---|---|
| Understanding | Generates text from a prompt | Editorial Intelligence™ analyzes every piece |
| Memory | Forgets after each conversation | Living Writer Brain™ learns continuously |
| Context | One conversation at a time | A structured model built across your full archive |
| Output | Generic responses | Editorial Coaching™ tailored to your voice |
| Planning | No sense of what you've already covered | Editorial Strategy™ tracks gaps and repetition |
| Revision | Rewrites on request, no scoring | Generate V2™ rewrites and re-scores automatically |
AI Workforce
Your AI editorial team
Six specialized agents, each focused on one part of the editorial process — not one general-purpose model trying to do everything.
Editorial Analyst
Runs the 12-dimension Editorial Intelligence™ analysis on every draft.
Editorial Coach
Turns analysis findings into specific, prioritized editorial recommendations.
Rewrite Specialist
Executes Generate V2™ rewrites, applying coaching recommendations to your draft.

Checks factual claims and flags evidence that needs a stronger source.
Security
Your content is yours
Editorial work is sensitive — unpublished drafts, voice, strategy. The platform is built to keep it that way.
Private Knowledge Sources
PDFs, transcripts, and videos you upload are scoped to your account only.
Encrypted in transit and at rest
All traffic runs over TLS; data at rest is encrypted by our managed infrastructure provider.
Secure authentication
Session-based auth with signature-verified tokens on every request.
Row-level security
Database access is enforced per-user with Postgres row-level security policies, not just application-layer checks.
GDPR-ready
Built with data minimization and user data control as defaults.
LGPD-ready
The same data-protection principles, aligned with Brazil's LGPD.
