NODUS - AI Idea Capture by Nodus

You ask an AI the perfect question, get a brilliant answer… and a week later it's gone — buried in an endless scroll of chats you'll never find again. NODUS makes sure that never happens.

WHAT IS NODUS
NODUS is a browser extension that captures, organizes and lets you reuse the best ideas, answers and prompts from your AI conversations — turning scattered chats into a personal knowledge base you actually own, right inside your browser.

HOW IT WORKS
1. Capture — one click saves any AI answer the moment it appears.
2. Organize — sort captures into projects, color-code them with tags, and link related ideas across platforms with Chains.
3. Reuse — search everything instantly and turn your best prompts into reusable templates.

WORKS EVERYWHERE YOU CHAT WITH AI
ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, Grok and DeepSeek — all from one place, no copy-pasting between tabs.

FEATURES
• One-click capture from 7 AI platforms.
• Chains — link related ideas across different AIs into one thread of thought.
• Projects — group captures by topic, client or goal.
• Color tags — label and filter your whole library at a glance.
• Full-text search — find any idea across everything you've saved in seconds.
• Prompt reuse — save your best prompts as templates and run them again anytime.
• Full chat capture — archive an entire conversation in a single click.
• Dark & light mode — easy on the eyes, day or night.

WHO IT'S FOR
Developers, researchers, writers, students, founders — anyone who uses AI every day and is tired of losing great answers in the scroll.

PRIVACY BY DESIGN
NODUS is local-first. Your captures live in your browser (chrome.storage.local) — no account, no sign-up, no cloud. Your conversations and prompts never leave your device. Only anonymous, aggregated usage stats are collected, and you can switch them off with one click.

FREE TO START
NODUS is free to use, with an optional PRO upgrade for power users (more queues, unlimited projects, HTML/DOCX export and encrypted backup).

16 LANGUAGES
NODUS speaks your language — fully available in 16 languages, from English and Portuguese to Japanese, Hindi and Turkish.
