Documents and notes decision
Guru
A narrow, self-hosted knowledge-and-search workflow (connectors, vector index, cited answers, and a simple verification flow) is realistic to build, but matching Guru's enterprise compliance, hundreds of connectors, and professional services is not practical for a small team.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

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 Guru alternatives, with the arithmetic →
What a replacement has to do
- Index sources, enforce permissions, serve cited answers to queries, surface verification status, keep content fresh
What it still won’t have
- SOC 2 / HIPAA compliance posture and attestation
- 100+ out-of-the-box connectors and maintained integrations
- Enterprise-grade governance & auditing (centralized policy enforcement, formal audit trails)
- Vendor-provided KM strategy, onboarding, and ongoing optimization services
- Built-in DLP masking, SCIM/SSO integrations, and formally supported permission inheritance
What remains hard
- Compliance and regulation
SOC 2 Type II, HIPAA, GxP compliance
- Integration maintenance
100+ source connectors
First-year cost
No published price
Guru does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted knowledge layer using Postgres + Milvus (or Pinecone) for vectors, Python (FastAPI) backend, Redis for job queues, and a React admin UI. Implement: (1) connectors to sync Slack and a single file source (Confluence or Google Drive) into normalized documents; (2) permission-aware ingestion that attaches user/group ACL metadata and enforces it at query time; (3) a vector+metadata retrieval API and an LLM answering endpoint that returns answers with inline citations and source links; (4) a simple verification workflow to flag stale docs and route drafts to an email webhook; (5) a browser extension or side-panel that lets users ask questions and view cited answers. Out of scope: SOC 2 attestation, 100+ connectors, enterprise SSO/SCIM, and professional onboarding services. Include error handling, unit tests for ingestion+retrieval, integration tests for permission enforcement, and deployment manifests for a single Kubernetes cluster.

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.
