Kelu vs Intercom Fin
Last reviewed:
Intercom Fin is Intercom's AI agent. It answers in the Intercom Messenger and many other channels, also runs on other helpdesks such as Zendesk, Salesforce and Freshdesk, and costs $0.99 per outcome. Kelu is an AI knowledge assistant on a flat monthly plan: one knowledge base answers tickets in Zendesk, Intercom, Freshdesk, Front and Linear, and also powers a docs widget, Slack and Teams bots, and an MCP server.
Choose Intercom Fin if you want an AI agent for customer conversations on many channels (voice, WhatsApp, social, Slack, Teams) with Procedures for multi-step tasks, and per-outcome pricing suits you. Choose Kelu if you want flat pricing and one knowledge base that answers tickets in your helpdesk and also runs your docs widget, Cmd+K search, internal Slack and Teams bots and an MCP server for AI coding tools.
Feature comparison
Intercom Fin details come from Intercom's and fin.ai's own pricing, help center and product pages, listed under the table.
Where Kelu focuses differently
Flat pricing instead of per outcome
Fin's per-outcome price is clear, but the bill moves with your volume: a launch or a bad-release week changes it. Kelu is a flat monthly plan with included question quotas, emails as you approach the limit, and no overage fees.
One knowledge base, beyond support
Fin is built for customer conversations. Kelu answers tickets too, and the same knowledge base runs your docs widget and Cmd+K search, Slack and Teams bots for your own team, and an MCP server for AI coding tools.
Sources from engineering, not only help content
Kelu indexes GitHub repositories, issues and pull requests, OpenAPI specs, Discourse, Stack Overflow and YouTube next to your docs and help center. Intercom's list of Fin sources does not name these.
Abstention enforced in code
When your sources don't cover a question, Kelu's abstention gate withholds both the excerpts and the citations, so the answer is "I don't know" rather than a guess. In a ticket, nothing is posted and your escalation tag is added.

Frequently asked questions
Can Kelu replace Intercom Fin?
For answering tickets and Messenger conversations from your knowledge base, yes: Kelu's Support Ticket AI runs inside Intercom, either as private-note drafts or as live replies. If you rely on Fin's Procedures, voice, WhatsApp or social channels, Fin covers ground Kelu does not. Kelu also stops answering a conversation once Fin joins it, so the two can run side by side.
Does Fin only work with Intercom?
No. Intercom sells Fin for other helpdesks too, including Zendesk, Salesforce Service Cloud and Freshdesk, with a $49/month minimum that includes 50 outcomes. Kelu works across Zendesk, Intercom, Freshdesk, Front and Linear on one flat plan.
How does pricing compare?
Fin costs $0.99 per outcome (a resolution or a Procedure handoff), plus Intercom seats if Intercom is your helpdesk. Kelu is flat monthly: Free (100 questions), Pro $99/mo or $79/mo billed yearly (1,000 questions, 5 knowledge bases), Enterprise custom. Kelu counts each answer as one AI question, whether or not it resolves the ticket.
Do I need to move off Intercom to use Kelu?
No. Kelu connects to Intercom with one Connect button, can index your public Intercom help center as a website source, and answers Intercom tickets and Messenger conversations. You keep Intercom.
How can I compare answer quality?
Test both on your own past tickets. Kelu's Simulations replay up to 100 recent resolved tickets and show each answer next to what your agent sent; Fin offers batch tests built from recent conversations. Kelu's retrieval combines vector and full-text search, rewrites the query with an LLM and reranks with a cross-encoder, and an abstention gate stops it answering when your sources don't cover the question.
