Open-source help center
Help customers.
Keep control.
OPAS turns your published knowledge into searchable guides and cited answers—then shows you what content is still missing.
A complete answer loop
From draft to better answers.
One workflow connects the article, the answer, and the improvement signal. Your chatbot never drifts into a second, stale knowledge base.
-
Publish knowledge
Import Markdown or write visually, apply your runtime theme, and move drafts to published guides without a rebuild.
-
Answer with evidence
Hybrid retrieval returns cited answers, keeps context for follow-up questions, and abstains when the evidence is weak.
-
Improve the gaps
Privacy-light signals reveal unsuccessful searches, low-confidence answers, and the context your team needs for human follow-up.
Runtime theming
One product. A help center that feels like yours.
Portable by design
Run it where your data already lives.
The application stays the same while the storage and deployment target change. No hosted content silo is required.
