The verdict
If you have a support team and want AI to resolve a share of conversations, I'd pick Intercom. If your problem is the content itself, pick Document360. Intercom is priced per seat, and Fin is billed separately by resolved outcome, which makes cost harder to forecast. Document360 is quote-based. In both cases, the AI is only as good as the articles behind it. Thin or out-of-date content produces confident wrong answers, so budget time to write and maintain it. If your team is small, Intercom's own Knowledge Hub is a sensible place to start before you add a separate documentation tool.

Who each is for
Choose Document360 if…
Pick Document360 if documentation is a real function in your company. It suits teams with several writers, approval workflows and a mix of public help centre, internal wiki and API docs. The writing agent can draft from videos and files, and someone with product knowledge should review the output before it is published. Ask which AI features and MCP access your quote includes. Skip it if you want a price today, or if a help centre inside your support tool is enough for the number of articles you have.
Choose Intercom if…
Pick Intercom if you are a support or customer experience team that wants an AI agent to resolve conversations alongside human agents in one inbox. Start with a trial and one channel, and measure resolved conversations and customer replies before you widen it. Check which tier holds workflow automation, private help centres and single sign-on, because the step up per seat can be large. Skip it if you want one flat, predictable bill, or a very simple helpdesk. Check your data region too, as the hosted MCP server runs only in US and EU regions.
