Docs that answer, everywhere developers work
API references, SDK guides, community threads, and changelogs unified into cited answers — on your docs site, in Slack, and inside the IDE via MCP.
Challenges in Developer Tools
Developers ask AI assistants, not your docs
Coding assistants answer from stale training data, hallucinating deprecated endpoints. You field tickets about APIs you fixed a year ago.
Community channels repeat the same questions
Your Discord answers the same install and auth questions daily, answers scroll away, and devrel burns out repeating themselves.
Keyword search fails on technical intent
A developer searching "rotate credentials" finds nothing because the page says "regenerate API keys" — then files a ticket or churns.
How Kelu helps
MCP server for in-IDE answers
Expose your docs as an MCP server so Cursor, Claude, and other MCP clients retrieve current documentation instead of guessing — search and ask_question tools, right in the editor.
Slack and Microsoft Teams bots with citations
The bot answers community questions instantly from docs, OpenAPI specs, GitHub READMEs, Discourse, and Stack Overflow for Teams, and gap analytics show which docs to write next.
Hybrid search and Cmd+K on your portal
Semantic + full-text retrieval matches intent, not just keywords, delivered as a widget, Cmd+K modal, or via the Search API.
Relevant sources & integrations
Common knowledge sources and integrations for Developer Tools teams.

Frequently asked questions
How does the MCP server work?
Each knowledge base exposes an MCP endpoint with search_<name>_knowledge_sources, ask_question, list_sources, and feedback tools, authenticated by a client key. Cursor, Claude, and other MCP clients retrieve your current documentation instead of answering from stale training data.
Can it index code repositories and API specs, not just docs pages?
Yes. GitHub sources index READMEs and Markdown docs (with webhook re-sync on every push), and OpenAPI sources turn your API spec into answerable reference content — alongside Discourse, Stack Overflow for Teams, and YouTube.
How does the Slack bot behave in a busy community?
It answers questions from your indexed docs with citations, so answers do not scroll away as tribal knowledge. Gap analytics then show which questions lacked good docs, giving devrel a prioritized writing backlog.
Can we build our own experience instead of using the widget?
Yes. The public streaming chat/search REST API lets you build fully custom in-product or in-portal experiences. React and JavaScript SDKs are on npm.
How long does setup take?
Most teams are live the same day. Connect a source — a docs URL, GitHub repo, Notion workspace, or a file upload — and Kelu crawls, normalizes, chunks, and embeds the content automatically. The website widget is a single script tag, and the Slack bot installs in a few clicks.
Are answers backed by citations?
Yes. Every answer from your docs includes a structured citations list with the URL, title, and excerpt of each source used, so users can click through and verify any claim against the original document.
Is my content used to train AI models?
No. Your indexed content, embeddings, and conversations are isolated to your workspace and are only used to answer your own questions. Content is never shared across customers, and data is encrypted at rest and in transit.
Is there a free plan?
Yes. The Free plan includes 1 knowledge base and 100 AI questions per month — no credit card required. Pro comes with a 14-day free trial, and Enterprise plans add SSO, source groups, and a custom SLA.
