Changelog

See what is new in Kelu, release by release.

v1.8.0September 29, 2026

Encrypted Credentials, Widget Form Deflection & Site Search

  • newCredentials you give Kelu for sources, helpdesks and AI providers are now encrypted at rest with AES-256-GCM
  • newSource visibility — mark a source's documents Public or Restricted; restricted documents never reach the widget, public API or MCP clients. Later replaced: there is no per-source setting now, visibility follows the knowledge base type, and every document in an internal knowledge base is restricted
  • newWidget form deflection — answer the question when a visitor submits your support form, before the ticket is sent
  • newReplace site search — the widget can take over your site's search box and Cmd+K (finds Mintlify's search box by itself)

  • newWidget event hooks and component styling options
  • newSign in with Google
  • newSign up with your docs URL — Kelu creates a knowledge base named after your company and adds your docs as its first source
  • newThe widget gets a public MCP server when its knowledge base has none

Confidence Scoring, Custom Answers & GitHub Code

  • newConfidence scoring — every answer is graded against its sources, and the assistant says so when your content does not cover a question
  • newCustom Answers — write your own question-and-answer pairs as a knowledge source
