DocGrab — Docs to Markdown / JSON

About

DocGrab — Save documentation as clean Markdown or JSON into a folder you choose

Turn the documentation you read every day into clean, offline files you actually own. DocGrab converts the page open in your browser — or an entire documentation site — into well-structured Markdown or JSON and writes it directly into a folder you pick on your computer. One click for a single page. One start URL for a whole site. No copy-pasting, no broken formatting, no servers in the middle.

Because DocGrab reads the page your browser has already rendered, it handles modern, JavaScript-heavy documentation that older “view source” scrapers cannot process. If you can see the content in your tab, DocGrab can save it — no Python, no headless browser, no command line, and nothing extra to install.

WHY DOCGRAB EXISTS

Documentation lives on someone else’s website. That works until you need it offline, behind a firewall, or for tools that expect local files. Sites go down, pages change, and links break.

DocGrab gives you a clean, portable copy of the docs that matter. Markdown is readable, searchable, and version-control friendly. JSON gives you structured data for automation and pipelines.

The result is your own personal documentation library: searchable, editable, and always available.

WHAT YOU CAN DO

• Save the current page — Convert your active tab into Markdown and/or JSON with one click.
• Crawl an entire site — Provide a docs root URL and download every page under it.
• Choose your folder — Files are saved exactly where you want using the File System Access API.
• Remove ads and clutter — Cookie banners, pop-ups, and overlays are stripped automatically.
• Pick your format — Markdown, JSON, or both.

SINGLE PAGE CAPTURE

Click “Download this page” and DocGrab will:

• Load all lazy content so nothing is missed
• Expand hidden sections and code samples
• Remove ads and overlays
• Convert the cleaned content into structured output

The result preserves headings, lists, code blocks (with language), tables, and links in clean, readable form.

SITE CRAWL

Capture entire documentation sites automatically:

• Parallel tabs (1–8) — control speed vs. resource usage
• Delay between pages — adjust for politeness
• Page limit — cap crawl size or set unlimited

DocGrab only follows links within your specified path, so crawls stay focused on the docs you want.

Progress is shown live, with logs and a stop button for full control.

OUTPUT FORMAT

Files are organized to mirror the original site structure:

your-folder/
docs.example.com/
guide/
getting-started.md
api/
endpoint.json

Markdown includes YAML front matter (URL, title, date, metadata).
JSON provides structured content for programmatic use.

WHO IT’S FOR

• Developers — offline API references and docs in your editor
• AI builders — clean Markdown/JSON for RAG, embeddings, and datasets
• Writers and researchers — archive and compare documentation
• Students — build a personal offline knowledge base
• Anyone tired of losing useful docs to broken links

PRIVACY

DocGrab is fully local:

• No accounts
• No analytics or tracking
• No data transmission
• No remote code execution

Everything runs in your browser. Files stay on your device.

HOW IT WORKS

DocGrab uses your browser’s rendered DOM, converts content locally, and saves it using the File System Access API. Crawling uses background tabs within limits you control.

GETTING STARTED

1. Open the extension side panel
2. Choose a folder
3. Select Markdown, JSON, or both
4. Click “Download this page” or start a crawl

TIPS

• Test small before large crawls
• Choose the correct start URL for scope
• Use lower speed settings for smaller sites
• Save both formats for flexibility
• Keep noise removal enabled for cleaner output

GOOD TO KNOW

• Pages that fail to load are skipped
• Only real links (<a href>) are followed
• Some browser pages cannot be accessed
• Background tabs may be throttled by the browser

EXAMPLE USES

• Build offline docs for frameworks
• Feed AI pipelines with clean structured data
• Archive pages before they change
• Track documentation changes over time with Git
