Where Kelu focuses differently

Knowledge isn't only in Microsoft 365

M365 Copilot retrieves from SharePoint, OneDrive, Outlook, Teams. Real-world knowledge lives across OneDrive, Confluence, Notion, GitHub, Google Drive, Zendesk, Slack, and files nobody has migrated. Kelu indexes all of them into one knowledge base — OneDrive is one source among 25.

Customer-facing surfaces

Copilot is internal — it helps employees inside Microsoft 365. Kelu ships a hosted widget for your docs / product site, plus Slack, Discord, and Teams bots for community and customer channels. Microsoft-hosted content can be a source; Kelu is the assistant that surfaces it externally.

Multi-helpdesk Support Ticket AI

Kelu runs Support Ticket AI inside Zendesk, Freshdesk, Front, Intercom, Jira SM, Linear, and Salesforce. Copilot's helpdesk story is limited to Microsoft's own tools (Teams). Different job.

Not locked to Microsoft 365 seats

M365 Copilot is priced per user (~$30/month) on top of your Microsoft 365 subscription. Kelu is standalone SaaS with a $0 free tier and a $99 Pro tier — priced by usage, not by Microsoft seat count.

Frequently asked questions

Should I use Microsoft 365 Copilot or Kelu?

If your use case is 'help employees do work faster inside Outlook, Word, Excel, and Teams', M365 Copilot is well-suited. If your use case is 'answer questions from our docs on our site, in Slack/Teams/Discord, and inside our helpdesk', Kelu is purpose-built for it. Many organisations use both.

Does Kelu index Microsoft 365 content?

OneDrive, yes — the OneDrive connector walks Microsoft Graph and indexes the documents in the drives it is given, under the permissions of the account it is connected with, on a 10-minute sync cadence. There is no SharePoint site connector; SharePoint-hosted pages can be reached with a website source.

Can I use Copilot inside M365 and Kelu for customer-facing?

Yes — they're complementary. Copilot helps employees write emails and analyse Excel; Kelu answers your customers on the widget, in support tools, and via MCP for AI IDEs.

How does pricing compare?

M365 Copilot is priced per Microsoft 365 seat (~$30/user/month). Kelu is flat monthly (Free / $99 Pro / Enterprise) and independent of your Microsoft 365 subscription — you don't pay per user for a customer-facing widget.

Is my data used to train models?

No. Your indexed content and end-user conversations are never used to train models. PII masking runs before every LLM call; zero-retention mode is a per-workspace toggle.
