Writing and content decision
Clearscope
A focused SEO content optimizer (topic research, term suggestions, LLM drafts, and local scoring) is realistic for one developer to build and maintain; matching Clearscope's full visibility tracking, enterprise features, and analytics is not practical without additional data, integrations, and ongoing operations.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Ingest a target topic or URL, fetch top SERP results, extract frequent terms and intent signals, produce an LLM-guided draft with suggested terms, and score/compare the draft against top pages.
What it still won’t have
- AI citation monitoring across chat models and aggregated visibility tracking
- Enterprise features: SSO, crawler whitelisting, dedicated account manager
- Pre-built analytics dashboards and long-term content monitoring
- Polished UX, collaboration/sharing features, and customer support
What remains hard

Runnable build prompt
Build a minimal Clearscope-like content optimizer using Node.js (Express) + Postgres + a simple React UI. In scope: (1) endpoint that accepts a topic or URL and queries Google SERP (using a SERP API) to fetch top 5 result URLs; (2) HTML fetcher + extractor that reads H1/H2 and body and computes term frequencies; (3) server integration with an LLM (OpenAI/Anthropic) to generate a draft from a prompt plus top-term suggestions; (4) scoring function that compares draft term coverage to aggregated top-page terms and returns a numeric score and suggested additions; (5) a web UI to create projects, run a report, view draft, and see the score; (6) logging, retry/error handling for network/LLM failures, and unit tests for extractor and scoring. Out of scope: long-term analytics dashboards, AI-citation tracking across chat models, SSO, enterprise billing, and large-scale crawling. Deliver with Dockerfiles and a README showing how to run locally and how to swap LLM and SERP API keys.

- Evidence score63
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.
