Introducing Kwern
Quick answer
Kwern opens to every maker today: one AI agent per marketing channel, drafts that wait for your approval, your own model key, from $29 a month.
Today we open Kwern to every maker. You give it the URL of what you built, and it puts an AI agent on each marketing channel your product has. The agents draft the work. You approve it. Nothing goes out without you.
The second to-do list
You shipped. Then a second to-do list started, under the real one: reply to the App Store reviews, answer the Reddit thread where someone asked for exactly what you built, update the keywords, fix the pages Search Console flags, look at the ad bids you set on launch day and never touched again.
It grows every time you ship, and it rarely gets opened. An agency would work through it, for $2,500 to $10,000 a month. Most of us building alone have neither that budget nor the hours. We built Kwern to work through that list with you.
How it works
- Paste your URL. An App Store listing, a Google Play listing, a website, or all three. Kwern reads it and writes the Foundation doc: who the product is for, what it promises, how it speaks. Every agent works from that doc, and you can edit it.
- Connect what you already use. App Store Connect, Google Play, Search Console, Google Analytics, PostHog, RevenueCat, Apple Ads, Google Ads, X, LinkedIn and GitHub. The agents read your real data through them. Each connector has its own page, screen by screen.
- The agents go to work. ASO, Apple Ads, SEO, GEO, Google Ads, X posts, X replies, Influencers, LinkedIn, Reddit, Hacker News, Competitors and Writer. Each one reads its channel and drafts what belongs there: a post, a reply, a listing change, a bid, a fix. The agents page says what each one reads and proposes.
- You decide. Every draft lands in one feed as a proposal. Approve it, edit it or reject it. Approve an X post and it goes out at its hour; approve a bid change and Apple Ads gets it. Replies on Reddit, Hacker News and X you post yourself, from your own account.
Why every action waits for you
There is no autopublish setting to switch on, and that is on purpose.
An AI that posts for you is a liability before it is a feature. One off-key reply on Reddit can cost you the account. One post in the wrong voice, and it is your name on it. So the drafts are cheap and your approval is the gate. Kwern's code holds the guard rails, such as acting only on the accounts your product connected. Every judgement lives in the agents' instructions, which you can read and edit.
Your own model key
Kwern runs on your own model key. Your provider bills the tokens at their price, and every run shows what it cost. No meter decides how much marketing you get, and no balance hides what you paid for. The plan covers the paid data reads Kwern buys for the agents, such as search, keyword and Reddit reads.
Apps first, fixes rather than reports
Apps are first class: an ASO agent, an Apple Ads agent, and RevenueCat revenue read per campaign. The AI marketing tools we compared stop at the website.
On the website side, SEO and GEO findings arrive as draft pull requests on the repository that serves the site. You review a diff, not a to-do list.
Open skills and an MCP server
The marketing skills the agents run are open Agent Skills files, readable without an account. You can see exactly what an agent was told before it drafted anything.
Kwern also has an MCP server. From Claude Code or any MCP client you can read your product's docs and its approval feed, approve drafts, put your own posts on the calendar, and call your connectors' APIs through Kwern, with the credentials kept on Kwern's side. Every X post of this launch went on the calendar that way.
What it costs
$29 a month for one product (Lite), $59 for three (Pro), $99 for five (Max), in US dollars, excluding VAT. Annual plans cost less. The pricing page has the details.
There is no free plan, because every agent run buys real data reads. In its place: no setup fee, no minimum term, a withdrawal right, and an agent you turn off costs nothing.
Kwern on Kwern
We run Kwern on kwern.app, and we start from zero. In its first week the X agent drafted seven posts and we rejected all seven. Our GEO probe found Kwern named in none of the 45 AI answers it asked for. We will publish what changes, the good and the bad.
If you are weighing Kwern against another tool, our comparisons say where the others are the better buy.
Paste your product's URL at kwern.app and see what the agents draft for it.
