Open-source builds that already do this
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. All Sofie Wiki alternatives, with the arithmetic →
What a replacement has to do
- User chat -> LLM generates/edits markdown wiki pages and cross-links them -> pages indexed for semantic search -> user queries via chat or search to get answers or open pages.
What it still won’t have
- Hosted AI service (built-in usage limits)
- SSO and custom domain in team plan
- SOC 2 / GDPR attestation (listed as ‘soon’)
- Priority support and managed team features
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal AI-driven wiki: Stack: Next.js (React) frontend, Node/Express backend, Postgres for pages and revisions, Redis for caching, Milvus or Pinecone for vector storage, OpenAI (or configurable LLM) for embeddings and completions. In-scope features: upload/parse documents, Notion import connector, embed and index text, semantic search API, chat endpoint that generates edits and new markdown pages, automatic simple cross-linking (detect and create links between titles), page view/browse UI with TOC and history, public read-only share links, user account auth (single-user). Out of scope: multi-user permissions/SSO, SOC2 compliance, hosted AI service. Require: error handling, input validation, retries for LLM calls, unit and integration tests for ingestion, search, chat-to-edit flow, and deployment scripts (Docker + basic Helm or Vercel instructions).

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.
