What it does

Research smarter,
highlight faster

🔎
Multi-Word Search
Enter several words separated by spaces — each gets a unique, vibrant color assigned instantly.
🎨
Per-Word Highlighting
Instantly see where each word appears across the entire page. Toggle any word on or off with a single click.
🧠
Smart Chip Panel
A floating panel lists every found word with its color and occurrence count. Click a chip to jump to the next match.
📋
Copy with Context
Copy the exact phrase, the surrounding sentence, or the full paragraph — your choice, one click.
💾
Persistent Storage
Save findings to IndexedDB. Export as CSV, JSON, or plain text whenever you need them.
🚫
Exclude Areas
Use CSS selectors to skip headers, sidebars, or ads — search only the content that matters.
📜
Search History
Quickly reuse past queries without retyping — your research workflow, remembered.
🌓
Adaptive Theme
Automatically follows your system's dark or light preference. No configuration needed.
🔐
Site Blacklist
Prevent Lexcope from running on sensitive sites — banking, email — for complete peace of mind.

How it works

01
Ctrl+F / Cmd+F
Open Lexcope
Press Ctrl+F (or Cmd+F on Mac) — Lexcope's toolbar replaces the browser's native find bar.
02
error warning critical
Type multiple words
Enter space-separated keywords — each word is instantly highlighted in a distinct color across the page.
03
Navigate with chips
Use the chip panel to toggle words on/off, see hit counts, and jump between every occurrence.
04
Copy matches
Hit "Copy Matches" to extract all found text with your preferred context — phrase, sentence, or paragraph.
05
Save & export
Save sessions to revisit later, or export everything as CSV, JSON, or plain text.
06
Blacklist sites
Add sensitive domains from the popup — Lexcope stays completely inactive on those pages.

100% on-device

Your data
never leaves

All searches and saved matches stay entirely on your device. Nothing is sent to any server — ever.

Blacklist sensitive domains like *mail*, *bank*, or drive.google.com — Lexcope won't even load on those pages, let alone read them.

Premium license verification is handled via a secure Cloudflare worker. No personal data is stored — only whether your license key is valid.

Site blacklist example
*mail*
*bank*
drive.google.com
paypal.com
zoom.com
