Open-Source Agent Skills

The pipelines we run in production at POPJAM, distilled into free MIT-licensed skills for Claude Code, Cursor, Codex, and any agent that supports the Agent Skills standard.

popjam-growth-engine

MIT

Turn one website URL into tested ad creatives

Runs POPJAM's full production pipeline inside your agent: brand research → audience segments → a bias-corrected synthetic persona panel → ad angles per audience and platform → real creatives (image, video, animation) → deterministic engagement simulation → iteration. Ends with a leaderboard of who converts and why.

Try: "Make ads for https://yourbrand.com"

award-landing-page

MIT

Design and build pages that sell

Landing, pricing, waitlist, and launch pages as one full deliverable: funnel research, art direction, conversion copywriting, distinctive design and motion, technical SEO, and CTA wiring, built to avoid the generic AI-template look.

Try: "Build a landing page for our launch on Thursday"

brand-guideline-extraction

MIT

Reverse-engineer a brand style guide from your assets

Point it at a folder of design assets (posts, ads, banners, decks, videos) and get a complete brand style guide (rules vs. variations vs. exceptions), plus a reusable style prompt block for on-brand AI image generation.

Try: "Extract brand guidelines from ./assets"

remotion-render-pitfalls

MIT

Ship Remotion animations that actually render

Render-breaking Remotion mistakes that pass tsc and eslint but crash at render time, battle-tested against POPJAM's production render pipeline. Useful for any strict Remotion setup that generates video programmatically.

Try: "Animate this product demo with Remotion"

Test Your Ads Before You Pay for Them

Instead of paying the platform to find your winning creative, POPJAM runs every variant past synthetic personas built from your real buyer segments. You get the reaction and the reasoning: which hooks hold attention, and which CTAs fall flat, before a single impression is bought. It works without any customer data, so there's no privacy or compliance exposure.

Frequently Asked Questions

What free AI marketing tools does POPJAM offer?

Three in-browser tools you can use right now without signing up: an AI persona generator that builds buyer personas from an audience description, an AI ad analyzer that tests your creative against synthetic personas and returns an engagement score with per-persona reasoning, and a pitch deck roaster that critiques your deck in the voice of top VC partners. POPJAM also publishes free, MIT-licensed agent skills for Claude Code and other coding agents.

Are these tools really free?

Yes. The in-browser tools are free to use with no credit card and no signup wall. The agent skills are open source under the MIT license on GitHub, so you run them in your own agent, and the only cost is whatever your agent provider charges for model usage. The full POPJAM platform has a free tier too: 500 credits, no credit card.

Can I test my ads with AI before spending money?

Yes. The free AI Ad Analyzer scores one creative at a time against AI buyer personas so you can catch weak hooks before launch. The POPJAM platform runs the full loop: it generates on-brand variants for Meta, Google, TikTok, LinkedIn, and Reddit, then simulates how each of your personas reacts to every variant, returning the reasoning rather than just a score.

What are the POPJAM agent skills for Claude Code?

Free, open-source skills that package POPJAM's production marketing pipelines as instructions any capable coding agent can follow: popjam-growth-engine (one URL to tested ad creatives), award-landing-page (pages that sell), brand-guideline-extraction (a style guide from your design assets), and remotion-render-pitfalls (programmatic video that renders reliably). Install them all with `npx skills add popjam-io/skills`; they work in Claude Code, Cursor, Codex, and any agent that supports the Agent Skills standard.

What is an AI persona generator?

A tool that turns a plain-language description of your target audience into structured buyer personas: demographics, psychographics, pain points, objections, and buying triggers. Marketers use them to sharpen positioning and creative angles; POPJAM goes a step further and uses the same personas to simulate how your ads will land before you pay for impressions.

How do the free tools relate to the POPJAM platform?

Each free tool is one step of POPJAM's loop, unbundled: personas, creative testing, brand analysis. The platform connects them: analyze your brand from a URL, build reusable audiences and persona panels, auto-generate platform-native ad variants, simulate every persona's reaction, and iterate on the winners. You can start free with 500 credits and no credit card.
