One platform, from ingestion
to answer

RAG answers with source citations, conversation memory, and streaming across every channel.

Websites, GitHub, Notion, Confluence, help desks, Drive — 24 source types in all, synced automatically.

Kelu watches which questions the assistant can't answer well, ranks them by volume, drafts the missing answer from your own content, and hands the draft to your team.

Kelu combines semantic vector search with full-text ranking and fuses the results — so "rotate credentials" finds the page titled "regenerate API keys," and an exact error code still matches exactly.

Embeddable Docs AI with chat, Cmd+K search, and reader sidebar modes — one script tag.

Kelu's browser extension (Chrome, Edge, Opera) opens your knowledge base in the browser's side panel.

Install the Kelu bot in your Slack workspace and every channel becomes a front door to your knowledge bases.

The Discord bot is switched off for now.

Bring your knowledge bases into the chat tool your company actually uses.

Ticket deflection, copilot drafts inside your helpdesk, and simulations.

Answer the question when a user submits your support form — deflect before the ticket exists.

Kelu reads incoming tickets in Zendesk, Intercom, Freshdesk, Front, and Linear, answers the ones it has grounded evidence for, and hands the rest to your team with your escalation tag — nothing is posted on them.

Simulations run the assistant against your past resolved tickets and produce a reviewable result set — each answer with its sources, confidence score and a human review — so you calibrate the confidence threshold on real data instead of guessing.

Questions per week, top sources, languages, knowledge gaps, and token counts per answer.

Indexed content and questions from the widget, API, and Ask can be scanned for PII (emails, names, phone numbers, card numbers, IBANs) and masked before they reach any model.

On any plan, Kelu can call the model on your provider account with your key.

Trust in AI answers comes from provenance.

An assistant you can't measure is an assistant you can't trust in production.

Your knowledge is your business.

Every Kelu knowledge base doubles as a Model Context Protocol server.

Everything the widget does is available to your code: streaming RAG chat, hybrid search, feedback, and suggested questions — via the public REST API, the hosted widget script, an MCP server per knowledge base, and the React and JavaScript SDKs.
