What Letterstory is, and the words we use
A two-minute tour of what the platform does and the handful of terms you'll see everywhere.
Letterstory writes, improves, and publishes content for your company. You decide what to say and how it should sound; the platform researches the topic, writes the piece in a consistent voice, improves it with links and visuals, and publishes it where you want it to go.
You can drive all of that from the web app at app.letterstory.com, or from your own tools: an AI agent connected over MCP, a command line, or plain HTTP. Every feature is the same underneath, so nothing you set up in one place is missing from another.
The words you'll see everywhere
Collection: a group of posts that publish together, usually one per site or blog. Settings like Auto-Pen and the publishing destination live on the collection, so every post inside it behaves the same way.
Post: one article. It starts as a headline, becomes a draft, and ends up published. Posts always belong to a collection.
Auto-Pen: the one-click writer. It runs three steps in order: Research (reads the web and writes an outline), Write (a writing kernel turns the outline into a draft), and Enhance (links, sources, visuals). See KB-301.
Writing kernel: the voice a draft is written in. There are eight shared ones, each with a distinct tone; your organization picks a default, and can build kernels of its own under Primitives → Kernels. See KB-701.
Guaranteed passes: what Auto-Pen's Enhance step adds to a draft (a brand mention, visuals, internal links, outside sources, and metadata). You switch each one on per collection, and can run any of them on demand from a post's Enhance panel. See KB-303.
Context: who you are and what you stand for: your company description, the topics you lead with, the stances you hold, and the competitors you track. Everything the platform writes is shaped by it.
Phantom site: a stand-alone publication Letterstory hosts for you, with its own name, look, and topic plan. It never carries your company's name; it exists to build an independent voice that AI answer engines and search cite. See KB-601.
Planner: autopilot for a collection: it picks topics, writes them with Auto-Pen, and publishes on a schedule.
Seer: a watcher on an outside signal (a GitHub release, a Notion page, a news query) that turns what it sees into headline suggestions or drafts.
Topic map: the pillars and spokes a collection plans to cover. Each spoke is one future post.
