Kelu vs Zendesk AI
Zendesk AI (Advanced AI / Answer Bot / Zendesk Copilot) is Zendesk's native AI, deeply integrated with the Zendesk suite. Kelu is a helpdesk-agnostic knowledge assistant with Support Ticket AI that runs inside Zendesk (and Freshdesk / Front / Intercom / Jira SM / Linear / Salesforce) plus a widget, Slack / Discord / Teams bots, and MCP.

Where Kelu focuses differently
Not locked to Zendesk
Zendesk AI is bundled into the Zendesk suite. If you use another helpdesk, or use multiple, or ever migrate — Zendesk AI doesn't come with you. Kelu's Support Ticket AI runs inside every major helpdesk, so the AI outlasts the helpdesk decision.
Same knowledge base beyond the helpdesk
Zendesk AI answers inside Zendesk. Kelu answers on your docs widget, in Slack / Discord / Teams bots, and inside AI IDEs via MCP — all from the same knowledge base. One source of truth, every surface.
Broader source coverage
Zendesk AI retrieves from Zendesk help center articles by design. Kelu indexes 25 source types including GitHub, Notion, Confluence, Google Drive, OneDrive, Salesforce, and every major helpdesk (including Zendesk tickets themselves) — internal knowledge as well as customer docs.
Flat pricing with public tiers
Zendesk AI is priced as an add-on to Zendesk seats plus per-resolution fees on Advanced AI. Kelu has flat monthly pricing (Free / $99 Pro / Enterprise) with clear included quotas — predictable regardless of ticket volume.
Frequently asked questions
Can Kelu replace Zendesk AI?
If you use Zendesk, yes — Kelu's Support Ticket AI runs inside Zendesk (as copilot drafts and auto-resolution) with a knowledge base that spans Zendesk articles, your product docs, GitHub, Notion, and more. If you use another helpdesk or several, Kelu covers all of them; Zendesk AI covers only Zendesk.
Does Kelu deflect on the Zendesk Messaging widget?
The form deflector (a standalone SDK) can answer questions on any support form, including the entry points of the Zendesk Messenger flow, with confidence-scored deflection. It runs before a ticket is created.
How does pricing compare?
Zendesk AI is priced as an add-on to Zendesk suite seats (Advanced AI is an additional per-seat add-on) with per-resolution fees on some Copilot features. Kelu is flat monthly: Free (100 questions), Pro $99/mo (1,000 questions, 5 KBs), Enterprise custom.
Do I need to leave Zendesk to use Kelu?
No. Kelu indexes Zendesk (help articles + tickets) as a source and runs Support Ticket AI inside Zendesk as agent copilot / auto-resolution. You keep Zendesk; you gain a knowledge base that also serves your widget, Slack, Teams, and AI IDEs.
How does answer quality compare?
Kelu layers full-text (BM25) and reciprocal rank fusion on top of vector search, rewrites the query with an LLM before search, and reranks with a cross-encoder. An abstention gate refuses low-confidence questions. LLM-as-judge evals score every answer for groundedness and citation quality.
