MarkGrab - Web Page to Markdown for LLMs

About

Turn any web page into clean, well-structured Markdown that's ready to paste straight into ChatGPT, Claude, Gemini, your notes, or a Git repo — in a single click. No copy-paste cleanup, no leftover navigation, ads, or script junk.

MarkGrab isolates the real content of the page (using Mozilla's Readability), converts it to tidy Markdown, and runs every table through a purpose-built processor so the structured data you actually care about survives the trip.

WHY MARKGRAB
- One-click conversion of the page you're already on — nothing to configure, nothing to sign up for.
- Output that's genuinely LLM-ready: clean headings, lists, and tables instead of messy pasted HTML.
- Best-in-class HTML table handling (the whole reason it exists — details below).
- Everything runs locally in your browser. No accounts, no servers, no tracking.

BEST-IN-CLASS TABLES
Most converters mangle real-world tables. MarkGrab doesn't:
- Expands merged cells (colspan / rowspan) into a clean, rectangular grid so no data is lost.
- Detects data tables vs. layout tables, so layout grids become readable text instead of broken Markdown.
- Recovers real data tables that content extractors often drop, and keeps them in their original section.
- Falls back to JSON or CSV automatically for tables that are too wide or too complex to read as a Markdown grid.
- Handles nested tables and multi-line cell content without breaking the output.

FEATURES
- Clean article extraction — strips nav, ads, headers, footers, and scripts; falls back to the full page when there's no clear article.
- Popup preview with a scrollable, monospace view of the Markdown before you use it.
- Copy — put the Markdown straight on your clipboard.
- Copy as prompt — wraps the content as a ready-to-send LLM prompt.
- Download .md — saves the Markdown as a file, named from the page title.

THREE WAYS TO TRIGGER
1. Click the MarkGrab toolbar icon.
2. Press Alt+M (rebindable at chrome://extensions/shortcuts).
3. Right-click the page and choose "Convert page to Markdown."

SETTINGS
Quick toggles, remembered between sessions:
- Include images (off by default) — keeps alt text when on.
- Include links (on by default) — keep or flatten links.
- YAML front-matter (on by default) — prepend title, URL, author, date, and site.
- Table format — Markdown table, JSON, or CSV.

PRIVACY & MINIMAL PERMISSIONS
- No host permissions — MarkGrab has no standing access to your sites. It only reads a page when you ask it to, on that single tab.
- No data collection and nothing sent anywhere — all conversion happens locally in the page.
- No remote code — all logic is bundled inside the extension.
- The only thing stored is your four UI preferences, kept locally in your browser.

Open any normal web page, trigger MarkGrab, and you've got clean Markdown ready to paste.
