Under a day for a first index: the 14-day trial is self-serve with a work email and no credit card, and the vendor quickstart says a documentation site of a few hundred pages indexes within minutes. On paid plans the vendor states most teams are live in less than 7 days.

Pros & Limitations

Editorial assessment

kapa.ai

Pros

  • ✓Every generated answer carries inline citations to the customer's own sources, and it is designed to say it does not know when those sources do not cover a question.
  • ✓One knowledge base serves the Retrieval API, a hosted MCP server and pre-built agents for a website widget, Slack, Discord, a support form, Zendesk and in-product use.
  • ✓Ingests more than 20 source types, from documentation sites, GitHub and OpenAPI specs to Zendesk tickets, Confluence and Notion, with continuous sync on paid plans.

Limitations

  • –Growth and Enterprise are quote-only, commercial plans carry a minimum annual commitment, and there is no self-serve card signup.
  • –Private sources, continuous sync, zero data retention and PII masking start on Growth, and SSO, SCIM, role-based access control and EU hosting are Enterprise features.
  • –The hosted MCP search tool returns results in about 3 seconds at the median and 4.5 seconds at the 95th percentile, and public OAuth servers allow 600 searches per user per day.
