Claude | Chunked Paste — Bypass Attachment Detection

Pastes clipboard content line-by-line in chunks to prevent Claude.ai from forcing large pastes into file attachments. Every line lands directly in the input field — fully in context, ready to work with.

Why You Need This

When you paste a large block of text into Claude's chat input, Claude automatically converts it into a file attachment — there's no prompt, no option to keep it inline. The core problem is how Claude processes attached files: rather than reading the full content into its context window, it may use grep or selective extraction to find relevant sections. This means Claude is working with a partial view of your content — which matters most when you need it to refactor, review, or reason over the whole thing at once.

Pasting inline forces the entire content into Claude's context window from the start. The script also prevents:

Forced attachment — your pasted text becomes a .txt file attachment instead of appearing in the input field
Lost formatting context — attachments are processed differently than inline text; Claude may not treat the content the way you intended
Interrupted workflow — you have to delete the attachment, then figure out another way to get your text into the input

This script splits your paste into small chunks with brief delays between them, staying under Claude's detection threshold so every line lands directly in the input field.

How It Works

Action	Result
Ctrl+V (normal paste)	If text exceeds the line threshold, it's split into chunks and pasted sequentially
Small pastes	Passed through normally — no interception
Alt+P	Toggle chunked paste on/off
Click floating 📋 button	Toggle chunked paste on/off

Features

Chunked Paste Engine

Splits clipboard content by lines and pastes in configurable chunk sizes
Configurable delay between chunks (default: 10ms)
Minimum line threshold before chunking activates (default: 5 lines)
Works with Claude's ProseMirror editor, including inside code blocks

Progress Indicator

Real-time progress bar showing chunks completed, total lines, and percentage
Auto-dismisses after completion
Can be disabled in settings

Floating Toggle Button

Small 📋 button in the bottom-right corner
Cyan glow = active, gray = disabled
Hover tooltip shows current state and keyboard shortcut

Configuration

All settings are accessible via your userscript manager's menu (click the extension icon):

Setting	Default	Range
Lines per chunk	50	1–500
Delay between chunks	10ms	1–1000ms
Min lines to chunk	5	1–100
Progress indicator	ON	ON/OFF
Enabled	ON	ON/OFF

Settings are persisted across sessions via GM_getValue/GM_setValue.

Installation

Install Violentmonkey (recommended), Tampermonkey, or Greasemonkey
Install this script
Paste into Claude's chat input as usual — chunking happens automatically for large pastes

Notes

Not a rate-limit bypass — this only prevents the paste-as-attachment detection, not any API or usage limits
Code blocks supported — special handling for ProseMirror code block nodes so formatting is preserved
Disable anytime — Alt+P or click the floating button to let normal paste behavior through
