The two halves

Most marketing tools ask you to write inside them. plgn does the opposite. You write where you already work, a terminal, with an AI assistant, and plgn holds the result.

The half	Where it lives	What it does
The workspace	useplgn.com, in a browser	Keeps your posts, pictures, topics and everything the system knows about your brand. Your team reviews here. Nothing publishes without a person.
The plugin	Claude Code, in your terminal	Adds twenty-seven commands starting with `/plgn`. They read your brand, write posts, make pictures, and save all of it into the workspace.

You can use the workspace on its own. You cannot use the plugin on its own for anything that needs saving: seven of its commands work with no account at all, and the rest need a workspace to write into.

What you need before you start

Claude Code, installed and working in your terminal. Everything else happens inside it.
A website for your brand. Not required, but the plugin reads it to learn how you sound, and a description you type by hand gives a thinner result.
A plgn workspace, for anything that saves. Free to create, and you can wait until after you have tried the free commands.

You never need an API key, a token or a password for plgn itself. If anything ever asks you to paste one into your terminal, something is wrong: sign-in happens in your browser, once.

Free commands and connected commands

The twenty-seven commands split into two groups, and the split is not about quality. It is about whether the result has anywhere to go.

	Free, seven commands	Connected, twenty commands
Account needed	No	Yes
Writes posts in your voice	Yes	Yes
Where the result goes	Text in your terminal	Saved in your workspace
Checked against your banned words	No	Yes, on the server
Pictures made	No	Yes
Scheduled	No	Yes
Your team can review it	No	Yes, on the board

A free command never reads or writes your workspace, signed in or not. When plgn is connected it reads websites and public posts through plgn's research tools (site_read, social_fetch, web_search), which cost a few points per read, so the server sees the addresses it reads and nothing else; without a connection it uses Claude Code's own web fetch. It cannot see your brand, so it works your voice out from your website and says so before it shows you anything. That guess is good enough to judge the tool by, and not good enough to publish thirty posts from.

Your first five minutes

Install the pluginTwo lines inside Claude Code add the plugin and turn it on. The install page has them.
Restart Claude CodeThis is the step people skip, and skipping it causes the single most common problem. Close it and open it again.
Run a free command/plgn demo https://yoursite.com gives you seven posts with no account and no sign-up.
Create a workspaceGo to useplgn.com and make one. This is where your posts and your brand will live.
Run /plgn setupYour browser opens once and asks you to approve access. Then the plugin reads your site and writes four things about your brand: how it sounds, who it talks to, what it sells, and words it refuses to use.
Write your first month/plgn month "your subject" --dry-run shows the plan and writes nothing. Run it again without the flag when the plan looks right.

The whole thing, in the order you type it

/plugin marketplace add PLGN-App/PLGN-CLAUDE
/plugin install plgn

   ... restart Claude Code here ...

/plgn demo https://yoursite.com
/plgn setup
/plgn month "Q3 launch" --dry-run

The words this documentation uses

Seven words appear on every page and each one means something narrower than it does in ordinary use. Learning them now saves you filing things in the wrong place later.

Word	What it means here
Brand	One business you publish for. A workspace can hold several, an agency runs one per client. Each has its own voice, its own posts and its own banned words.
Post	One piece of copy for one platform. The same idea written for LinkedIn and for X is two posts, not one post in two places.
Draft	A saved post that is not going anywhere yet. Drafts are the safe state: nothing publishes from a draft, and a run that goes wrong leaves drafts you can delete.
Topic	A repeated argument the brand makes, not a category. "Migration stories" is a topic. "Educational" is not. It would fit any business in any market.
Offering	One thing the brand sells, saved as its own record with its benefits. Not a knowledge entry, and not the same as a post about it.
Campaign	One thing the brand is saying for a while, with a start and an end. Ramadan, a launch, a season. Posts inside it inherit its message and its rules, and stop inheriting them when it ends.
Point	What making a picture costs. Points come with your plan, and you can buy more. What one picture costs depends on the model it is made with, and every command that spends them states the cost before it spends anything.
