PastePolish

PastePolish is an Obsidian plugin that fixes the “spatial bloating” commonly introduced when pasting content from AI assistants such as ChatGPT, Gemini, or Claude.

When rich text is converted into Markdown, it often produces excessive blank lines. PastePolish intelligently compresses these gaps while preserving Markdown structure, allowing you to clean pasted content safely in Edit Mode.

✨ Features

Smart Markdown Protection

PastePolish detects Markdown block elements and preserves the required buffer lines above them.

Protected structures include:

• Tables
• Devidier
• Code blocks
• Callouts

This prevents formatting breakage caused by overly aggressive whitespace removal.

Gradual Refinement (x → x − 1)

A unique mode that reduces consecutive blank lines one step at a time.

This allows you to gradually adjust the spacing of a document instead of applying a single irreversible cleanup.

Aggressive Cleanup

Instantly collapse all redundant blank lines into exactly one line, restoring clean Markdown formatting with a single command.

Preview

Example showing text pasted from Gemini Web. HTML-to-Markdown conversion introduced excessive blank lines, which PastePolish cleans up while preserving structural spacing.

⚙️ Settings

Compression Mode

Gradual (Default) Reduces consecutive blank lines by one per execution.

Aggressive Collapses all consecutive blank lines into exactly one.

🔍 Implementation Overview

PastePolish uses a context-aware regex engine rather than simple global replacement.

Block Detection

The plugin identifies Markdown block syntax using patterns such as:

/^[ \t]*([-=]{3,}|\||[\~]{3,}|>|[-*+][ \t]+|\d+\.[ \t]+|\$\$|#{1,6}[ \t]+)/

These heuristics allow the plugin to maintain safe spacing around structural elements.

State-Based Gap Reduction

A newline counter tracks consecutive blank lines and safely reduces them while respecting platform-specific line endings (\n or \r\n).

⌨️ Hotkeys

Hotkeys can be configured in Settings → Hotkeys.
