AI Documentation Crawler & Knowledge Base Builder

This n8n template automatically crawls technical documentation websites, scrapes their content, and converts it into clean, structured, developer-friendly documentation.
Each page is organized into folders and saved as Google Docs, making it easy to build or maintain an internal knowledge base.

Who’s it for

• Developer teams maintaining internal or external documentation
• SaaS companies onboarding users or support teams
• AI builders creating documentation-based knowledge bases
• Anyone who wants to turn raw docs into structured, readable references

How it works / What it does

1. Manual Trigger

   • The workflow starts manually whenever you want to crawl or refresh documentation.

2. Documentation Discovery (Crawler)

   • The workflow crawls a root documentation URL and generates a sitemap of all discoverable documentation pages.

3. URL Processing

   • The sitemap is split into individual URLs.
   • The workflow dynamically analyzes URL depth to recreate the documentation hierarchy.

4. Folder Structure Creation

   • A parent folder is created in Google Drive for the service.
   • Subfolders are automatically generated to mirror the documentation structure (based on URL paths).

5. Content Scraping

   • Each documentation page is scraped using the Olostep API.
   • Clean markdown content is extracted from the page.

6. Information Extraction

   • AI extracts structured technical details such as:
     • API summaries
     • cURL examples
     • Authentication methods
     • Key notes and pitfalls

7. AI Documentation Generation

   • An AI agent transforms the scraped content into a polished, human-readable API reference or guide.

8. Document Creation

   • A Google Doc is created for each documentation page.
   • The generated content is inserted into the document and saved in the correct folder.

9. Rate Control

   • A wait step prevents API throttling during large documentation crawls.

The result is a fully structured documentation library generated automatically from live documentation websites.

How to set up

1. Import the template into your n8n workspace.
2. Set the root documentation URL you want to crawl.
3. Connect your Google Drive and Google Docs accounts.
4. Add your Olostep API key and AI model credentials.
5. Execute the workflow to generate your documentation library.

Requirements

• n8n account (cloud or self-hosted)
• Olostep API key
• Google Drive & Google Docs access
• AI model provider (OpenAI or Gemini)

How to customize the workflow

• Limit the number of pages crawled per run.
• Adjust AI prompts to match your documentation style.
• Store results in Notion, Confluence, or Markdown files instead of Google Docs.
• Add vector storage (Pinecone, Supabase) to turn docs into an AI knowledge base.
• Schedule automatic re-crawls to keep documentation up to date.
