You don't need a marketing team. You need the right stack.

A full marketing team runs 15,000 to 30,000 EUR a month. A content writer, a media buyer, a video editor, a CRO specialist, a copywriter. Most solo founders and creators skip marketing entirely because they can't afford a single one of those roles.

Five free tools change that equation. Each one handles a job that used to require a dedicated hire. They run inside Claude Code, install in under a minute, and cost nothing.

In this guide, you get for each tool: what it does, how to install it, and the exact use case where it saves you the most time. No theory. Just links and concrete steps.

Marketing Skills: 20+ agents in a single install

🔗 github.com/coreyhaines31/marketingskills
💡Why it's useful

A collection of 20+ specialized agents for Claude Code. Copywriting, SEO audits, CRO reviews, analytics setup, content strategy, landing page optimization. Each agent brings domain expertise that a marketing hire would take months to build.

⚙️How to use it
1
Clone the repo and add it to your Claude Code skills folder. Each skill loads on demand.
2
You call each skill when you need it. /copywriting writes your landing page. /seo-audit scans your site. /page-cro tells you what's killing your conversions on any page.
3
Bonus: the extended collection (40+ skills) is available at github.com/alirezarezvani/claude-skills.
🎯Tip
→
Start by running /page-cro on your homepage. Most founders have 3 to 5 conversion killers they've never noticed. The skill spots them in seconds.
Key takeaway

One install replaces a copywriter, an SEO consultant and a CRO specialist. You fire up each agent from your terminal whenever the task lands.

Humanizer: strip the AI voice out of your copy

🔗 github.com/blader/humanizer
💡Why it's useful

AI-generated text has a signature. Readers feel it before they can name it. Phrases like "in today's landscape" or "it's important to note" signal that no human wrote this. Your audience scrolls right past.

⚙️How to use it
1
Install the skill with: git clone https://github.com/blader/humanizer ~/.claude/skills/humanizer/
2
Run /humanizer on your text. It's scored across four dimensions: Directness, Rhythm, Trust, Authenticity. Each one scored out of 10.
3
Below 35/50, the tool rewrites until the text reads like a human wrote it.
4
Run all your client-facing copy (landing pages, emails, posts, ad copy) through Humanizer before it ships to production.
🎯Tip
→
Paste your best email (the one that converts highest) into Humanizer and note the score. That score becomes your benchmark. Run all your future copy through until it matches or beats that number.
Key takeaway

AI text that sounds like AI gets ignored. Humanizer catches the patterns your readers already pick up on and rewrites until the voice rings true.

Claude Ads: complete ad campaigns from a single prompt

🔗 github.com/AgriciDaniel/claude-ads
💡Why it's useful

A media buyer costs 2,000 to 5,000 EUR a month to manage your ad accounts. Claude Ads generates complete campaign structures from a single prompt: headlines, descriptions, audience targeting, bid strategies, creatives tailored to Google, Meta, YouTube and LinkedIn.

⚙️How to use it
1
Install the skill from the repo and load it into Claude Code.
2
Describe your product, your audience and your budget. The skill builds the full campaign: ad groups, keyword targeting, negative keywords, responsive search ad variations, A/B test structures.
3
You copy the output into your ad platform and launch.
🎯Tip
→
Start with a Google Search campaign on your highest-intent keyword. Claude Ads generates 15 headline variations and 4 descriptions. Test them against your current top performers for two weeks.
Key takeaway

You can launch a multi-platform ad campaign in an afternoon. Claude Ads handles the creative and targeting structure. You sign off on budget and strategy.

Claude Code + Higgsfield: cinematic ad videos on autopilot

🔗 higgsfield.ai
💡Why it's useful

Higgsfield's Marketing Studio generates cinematic product videos, UGC ads and brand content. Claude Code drives the browser, writes the prompts and sends the jobs to Higgsfield without you ever touching the interface.

⚙️How to use it
1
Install the Playwright MCP server so Claude can drive your browser. Ten-minute setup.
2
Describe the video you want. Claude generates the Seedance 2.0 prompt with the right camera language, style modifiers and negative prompts.
3
It opens Higgsfield, pastes the prompt, uploads your product photo and kicks off the render. One command, done.
🎯Tip
→
A video editor costs 3,000 to 8,000 EUR a month. This pipeline produces unlimited variations for the price of Higgsfield credits (which start free).
Key takeaway

Claude writes the prompts. Higgsfield renders the video. You approve the final cut. A complete video ad pipeline, zero manual editing.

Seedance 2.0 Skills: free prompt templates for your ad videos

🔗 github.com/dexhunter/seedance2-skill
💡Why it's useful

Seedance 2.0 powers Higgsfield's video generation. Render quality comes down to prompt quality. A bad prompt gives you generic footage. A structured prompt (camera angles, motion types, lighting, style) gives you a cinematic result.

⚙️How to use it
1
Clone the repo and add the templates to your skills.
2
The collection includes frameworks for product ads, UGC content, cinematic brand films and social media hooks. Each template follows the structure that works best with Seedance: Subject, Action, Camera, Style.
3
Load a template, swap in your product details, generate. Zero trial-and-error on the prompt.
🎯Tip
→
Start with the "product turntable" template. Upload a photo of your product, run the prompt, and you've got a 360° video in under 5 minutes. Perfect for your hero section or your product pages.
Key takeaway

Prompt engineering is the bottleneck of AI video. These frameworks remove the guesswork. You pick a template, plug in your details, and get a consistent result.
