Should you build your own MarketMaster?
Turns a researched website into reviewed ads, social posts, video, and email campaigns
A solo campaign generator that scrapes one site and prompts an LLM for coordinated copy is a realistic weekend build. MarketMaster's paid value is the deeper research, multi-format media generation, deterministic quality gates, independent review, integrations, scheduling, and maintained publishing workflow.

Build me a personal AI campaign generator inspired by MarketMaster. Requirements:
- Use Node.js 22, Express, server-rendered HTML, and better-sqlite3.
- Run locally on port 4860 with no accounts, analytics, or telemetry.
- Accept one public website URL and fetch only same-domain HTML pages.
- Extract visible product, audience, pricing, proof, brand voice, and CTA text.
- Show the extracted campaign brief in an editable approval form before generation.
- Use one OpenAI or Anthropic model selected with variables in .env.
- Generate one campaign containing three ad concepts, five social posts,
one five-slide carousel outline, one short-video script, and one email.
- Keep every asset grounded in approved brief fields and flag unsupported claims.
- Add deterministic checks for missing proof, vague CTAs, generic hype, and
platform character limits; show warnings beside each affected asset.
- Let me edit, approve, and export the package as Markdown and JSON.
- Save briefs and campaigns in SQLite with created dates and approval status.
- Include fixture-based tests for extraction, claim flags, and exports.
- Secrets stay in .env and fetched page text stays on the local machine.
- Out of scope: image/video generation, multi-model review, OAuth integrations,
automatic publishing, scheduling, collaboration, billing, and hosted accounts.
- Include a README with setup, model costs, robots.txt etiquette, and limitations.The prompt opens pre-filled in your agent. Review it before running.
What would building your own look like?
Read one public website, extract a campaign brief, generate coordinated channel copy, review it, and export the approved package.
What you will need
- LLM API key
- website text extraction
- SQLite
- hosted or local web app
They pay to move from a website to a coordinated, reviewable, publish-ready campaign without maintaining research, media, validation, integration, and delivery infrastructure themselves.

Nothing worth pointing at. That’s why the prompt exists.

Is it cheaper to build or buy MarketMaster?
Adjust the numbers: hours to build, your hourly rate, running costs and the subscription price.
Over 24 months, subscribing is cheaper.
Starting hours estimated from the analysis (multi-day). Does not price what you give up (support, integrations, security).
Can I rebuild MarketMaster?
Kinda. The core of MarketMaster is buildable in a weekend with the prompt on this page, but there are real gaps: multi-model campaign review, generated image and video assets. Read the honest list above before committing.
How much does MarketMaster cost?
MarketMaster costs about $29/mo (Starter, checked 10/20/2026), which is $290 per year.
What do I lose by replacing MarketMaster?
Honestly: multi-model campaign review; generated image and video assets; live social and email integrations; scheduled publishing and delivery history; maintained ad-pattern and platform-limit references. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to MarketMaster?
No mature open-source alternative worth pointing at, which is exactly why the one-shot prompt on this page exists.
