X Post Agent
Most accounts die of silence. This agent keeps your posts planned ahead: it reads what your audience is talking about and what your own last posts did, and drafts each one in your voice for its own day and hour. You read it, and it goes out from your own account.
The compose box is still empty
You know you should be posting. You have known it for months. The account has 300 followers and a last post from the week you launched, and every time you open the compose box at eleven at night you write half a sentence and close it again. Meanwhile the people you are competing with post every day, badly, and it works, because on X the person who turns up is the person who gets read.
What is marketing on X?
Marketing on X is turning up in the timeline every day with something worth reading. There is no way to buy past that. An account that posts three times in March and nothing in April reaches nobody in May, and the people who do well on X are mostly the people who did not stop. The work itself is small: one post, most days, in a voice that sounds like a person. It is the relentlessness that is hard, and it is the first thing to go the week you are shipping.
An X agent is the relentless half of that work, done before you open the app. It reads what the people you are writing for are talking about, and what your own last posts actually did, and plans the posts for the days ahead that have none, each on its own day and hour; a day that holds nothing but promotion still gets a post on something else. Kwern holds your X connection, so approving a draft schedules it and it goes out from your own account at its hour. The week is spread across the few topics your product owns, with promotion kept to a small share of it. On the days a thread works best, it writes a thread, built on the key takeaways of one of your published articles when there is one, and when a post in your niche deserves an answer with more to it than a reply, it drafts a quote. The link stays out of the body and goes in a first reply you post yourself, which is the instruction the template ships with.
What it leaves you
The posts for the days ahead that have none, each planned for its own day and hour, with the link kept for a first reply you post under it: single posts, threads (on an article's key takeaways when you have one), and quotes of posts it can add to. Replies to other people are the X replies Agent's job, on the same channel and in the same feed.
The skills it runs
A run may activate these and nothing else. Every one of them is open: read the file before you turn the agent on.
What an X agent costs elsewhere
These are the prices on those companies' own pages on the day shown, and they are the only figures here we can stand behind. Kwern publishes no audience figure for X, because we have not measured one.
Kwern against the alternatives
Goes out from your own account, after you have read the draft
An agency posts from a shared login, the login that eventually leaks. A point tool posts from your account, but from a queue you filled three weeks ago; some suites publish with no stop in between.
Keeps turning up in the timeline, whether or not you remembered
A scheduler posts what you put in it and stops when you stop. An agency and a suite do turn up, on a calendar filled a month early — which is the next row.
Reads what your audience is posting today before it writes
A content calendar is generated before any of it happened. Kwern reads the day's timeline and what your own last posts did, so the draft answers the week rather than repeating it.
Written in your voice, about what your product really does
A suite drops your product name into a template; a copywriter has never opened what you built; a scheduler does not write. Kwern keeps the link out of the body and in a first reply you post yourself.
Every agent in every plan, from $29 a month
Suites run $20 to $1,000 a month and $5,000 for a done-for-you tier. Point tools charge a seat per channel. An agency is a retainer agreed before anything ships. Doing it yourself costs nothing but the evenings.
The model runs on your own key, at the provider's price
Across the 11 models Kwern vets, the provider bills you and nobody marks a token up. Credits bought from a suite never itemise the markup; an agency keeps its margin inside the retainer.

This Agent runs about 10 times a month. The tokens those runs spend are billed to you by your own provider: $0.10 per million in on gpt-6-luna, $10 on gpt-6-astra. Kwern never resells a token and never marks one up.
Three plans, every agent in each
Your model key, your accounts, your approval on every post. The plan decides how many products you run.
