Knowledge Assistant

Let users ask your docs anything. Anywhere.

Give users natural-language answers from your documentation and the additional sources you provide.

Grounded answers

Give users a natural-language way to find answers, with responses grounded in your docs and additional sources you choose.

Ask anything...

Relevant context

Your assistant retrieves the most useful sources for each question, keeping answers focused and easy to verify with links back to relevant docs pages.

Embed anywhere

Add your Knowledge Assistant to any web page with a simple script tag, so users can get answers wherever they need help.

Additional sources

Add website content, PDFs, and other files as sources for your assistant, so answers can draw from more than your docs.

Agent-ready docs

Docs that agents can find, read, and query.

Every deployment publishes clean Markdown, a complete map of your documentation, and a read-only MCP server—so your users can bring authoritative product knowledge into the tools where they work.

Every page is available as clean Markdown

Your users and their agents can skip HTML parsing and read token-efficient Markdown versions of every published page.

Let users ask your docs from their agent

Each docs site can expose a read-only MCP server, so users can query your documentation from Cursor, Claude Code, Codex, or any compatible MCP client.

Edit Content

Flexible workflows for every team.

Make updates in Radiant’s visual editor, keep content in a GitHub repo your team controls, and preview changes before they go live.

Visual editor

Create and update docs directly in Radiant, with full control over pages, navigation, content, images, and components. No code required.

Team-owned repository

Keep your docs content in a GitHub repo your team controls. Changes can move through your usual review and release process before Radiant publishes them.

Components

Use ready-made components to keep complex content clear, consistent and visually organized.

Preview before you push

Use the Radiant CLI to preview docs while you make changes locally. What you see here is what you'll see once you deploy your changes.

Writing agent

A writing partner that knows your docs

Ask for a rewrite, a new page, or a structural update. The agent explores your docs repository, edits your draft, and checks its work before you publish.

  • Uses your entire docs repository as context
  • Edits pages, navigation, and configuration
  • Validates MDX, links, and components automatically
