For marketing teams choosing an agent

Open-source AI marketing agents that land work as a diff

The open-source AI Operating System

An AI marketing agent drafts the marketing work itself and then acts in your tools: the launch note, the campaign variants, the weekly digest. Kortix is the open-source AI Operating System, and its voice file, claims list and approval rules are files in a repo your team owns.

Nothing merges itself: work reaches main through a change request a person approves, unless an admin granted the merge capability.

Four marketing jobs a team can hand off

Each card is what comes back, in the shape a person reviews.

Launch note

Writes the note once and fits it to every channel.

One brief returns an email, a Slack post and a social draft, each on its own change request.

launch-note-email.diffWhat comes back
Subject: Big news from Acme
Subject: Exports get four times faster on Thursday
We are thrilled to announce a big platform update.
On Thursday Acme ships faster exports, CSV import and an audit view.
one draft, three channels

Campaign variants

Drafts ten subject lines against your voice file.

Each variant is checked against the banned words in the skill before it reaches the draft.

Claims audit

Reads a live page and flags the sentences you cannot support.

Every flag names the line, the page and the source, date or number that is missing.

Competitor digest

Reads the rivals' changelogs on Monday and writes the note.

Plan changes, renamed features and price moves arrive as a short digest, with a link on every line.

Where the shortlists stop

Deskferry's five factors leave approval out, and Campaign Agent's governance does not cover self-hosting or what leaving costs.

What open source changes for a marketing team

Kortix is the open-source AI Operating System: your agents, their skills, your company memory, and every connector in one git repo you own, with the agents working on real cloud computers.

Questions a marketing team asks before it picks an agent

The plans and the approval step, in the words the vendors use.

What can AI agents do for marketing?

An AI marketing agent drafts and adapts the work a team repeats: launch notes across channels, campaign variants, an audit of the claims on a live page, and a weekly competitor digest. It works inside the tools the team already uses, so a draft arrives with its numbers and links.

What are the big 4 AI agents?

There is no fixed list. The four names usually meant are ChatGPT, Claude, Gemini and Microsoft Copilot, general assistants that answer in a chat window. A marketing agent is a different product: it runs the job in your tools and hands back a draft you can review.

How much does an AI agent cost?

Published prices run from nothing to about $1,250 a month. Deskferry charges $49 a month for 5,000 credits, Blueshift's plans start at $1,250 a month billed annually, and Salesforce Campaign Agent publishes no price. Kortix is $0 with 500 credits a month on your own provider keys or ChatGPT subscription, then from $50.

Which AI agent is best for marketing?

Kortix, for a team that has to show its work. The voice file and the claims are a skill in your repo, a draft lands as a diff a person approves, and self-hosting is free. Deskferry suits a team that wants ready-made agents; Campaign Agent suits a Marketing Cloud account.

Do these agents send a campaign without a person?

That depends on the gate you set. File work reaches main through a change request a person approves, unless an admin granted the merge capability. A connector call runs when your policy allows it, and approval gates are off until you set them.

Can our voice and banned words live in a repo we own?

Yes. The tone, the claims you can support and the words you never use are markdown files a session loads, and a change to any of them arrives as a line in a diff. The platform comparison shows where the other tools keep theirs.

Hand the next launch note to an agent, then read the diff.

Free is $0 with 500 credits a month, on your own provider keys or ChatGPT subscription, and a paid month draws on one shared credit pool.
