SEO and marketing decision

MarketMaster

A focused self-hosted replacement that performs research, brief generation, evidence checks, and asset export is realistic for a single technical user in ~1 week; reproducing MarketMaster’s full multi-model review, high-volume media, and polished multi-platform publishing breadth is more involved and leans toward a paid product.

No open-source build does this yet

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.

What a replacement has to do

  • Research website → build Brand Kit → generate campaign brief and assets with LLMs → run automated evidence checks → export or publish assets

What it still won’t have

  • High-volume built-in AI media caps (images/videos) and managed media pipelines
  • Multi-model independent review (Anthropic + OpenAI/Google) guarantee without additional API spend
  • Built-in integrations breadth and per-platform publishing polish (carousels, reels, provider-specific formats)
  • Operational monitoring and strategic product reviews included in Studio plan

What remains hard

  • Product polish and ongoing maintenance

Runnable build prompt

Build a minimal self-hosted MarketMaster-style Ad Studio using FastAPI (backend), React (frontend), Postgres (data), Redis (jobs), and OpenAI/Anthropic (LLM) plus a generative-image/video API. In scope: website crawler & HTML parsing to extract product/pricing/proof/logo/colors; Brand Kit creation and storage; one guided Studio UI implementing Source → Brief → Ad pattern → Create → Review → Export; LLM-based asset generation for static ads and platform-specific copy; an Evidence Engine that re-checks claims against crawled pages and blocks publishing on fail; export to ZIP and a single-platform publish adapter (e.g., post to X via OAuth). Out of scope: multi-model reviewer redundancy beyond one reviewer, high-volume managed media pipelines, and agency-level analytics. Include error handling, retryable background jobs, API usage rate-limiting, and unit + integration tests for the core flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
