Where Kelu focuses differently

1

Query rewriting and an answer gate

Both products use hybrid search with reranking. Kelu also rewrites the question with an LLM before it searches, so 'how do I auth' can find the same chunks as 'authentication SDK setup guide'. A coverage check then decides whether your sources answer the question at all. If they don't, Kelu says it doesn't know and shows no citations.

2

Git-push sync for repos

Add Kelu's webhook to your GitHub repository once. Each push starts a sync, and files that didn't change are skipped. Docs, code, issues, pull requests and discussions are separate sources, so you index only what you want answered.

3

Self-serve, with bots on Pro

Sign up, connect a docs URL and get answers without a demo call. The Free plan includes the widget, form deflector, REST API and MCP server. Slack and Microsoft Teams bots come with Pro, not only with an enterprise contract.

4

Full public pricing with a free tier

Kelu publishes all plan limits and prices openly. The free plan includes 1 knowledge base, 500 indexed pages and 100 AI questions per month — enough to evaluate the platform end-to-end without a sales conversation.

Frequently asked questions

How is Kelu different from Inkeep?

Both turn documentation into AI answers with citations, with a widget, bots, an API, an MCP server and a support form. Inkeep has also become an agent platform, with a visual builder and a TypeScript SDK for custom agents. Kelu is a packaged product with public prices and a free plan, Slack and Teams bots on Pro, and Support Ticket AI in Zendesk, Intercom, Freshdesk, Front and Linear.

Can I migrate from Inkeep to Kelu?

Yes. Kelu indexes the same kinds of sources — docs sites, GitHub repos, Notion, Confluence, Google Drive and solved Zendesk tickets — so migration is usually reconnecting your sources and swapping the widget embed or API calls. Kelu can't add Slack, Discord, Freshdesk or Help Scout as sources.

Does Kelu support the same integrations?

Kelu ships a web widget, a support form deflector, Slack and Microsoft Teams bots, an open REST API with WebSocket streaming, an MCP server per knowledge base, and Support Ticket AI in Zendesk, Intercom, Freshdesk, Front and Linear (tickets) and Freshchat (live chat). React and JavaScript SDKs are on npm. Kelu's Discord bot is switched off for now.

Do answers include citations?

Yes. Each answer built from your content links to the exact source passages it used. When your sources don't cover a question, Kelu says it doesn't know and shows no citations.

Is my data used to train AI models?

No. Your connected content and your users' conversations are never used to train models. Content is indexed only to answer questions for your knowledge base. PII masking and zero data retention are available on every plan.

How much does Kelu cost?

Pricing is public. Free is $0, with 1 knowledge base, 500 indexed pages and 100 AI questions a month. Pro is $99/month, or $79/month billed yearly, with a 14-day free trial. Enterprise is custom. There are no per-seat fees. See the pricing page for details.
