N

An open-source workflow automation tool that can be self-hosted for maximum privacy and customization. n8n is popular among developers and tech-savvy businesses who want the flexibility of Zapier/Make but with full control over their data and infrastructure. It supports AI integrations and custom code execution within workflows.

AI systems designed and trained to perform a specific, well-defined task — such as playing chess, recognizing faces, translating language, or recommending products. All commercially deployed AI systems today (including ChatGPT, Claude, and Gemini) are narrow AI, despite their impressive breadth. They cannot transfer their skills to genuinely new domains without retraining.

A subset of natural language processing focused on the AI's ability to produce human-like text from structured data or instructions. NLG powers AI writing tools, automated report generation, and chatbot responses. Modern LLMs represent the most advanced form of NLG ever developed.

A branch of AI focused on enabling computers to understand, interpret, and generate human language. NLP is the foundation of every chatbot, voice assistant, search engine, and language model. Modern NLP is dominated by transformer-based large language models that have dramatically outperformed earlier rule-based and statistical approaches.

A subset of natural language processing focused on the AI's ability to comprehend the meaning, intent, and context of human language — not just recognize the words. NLU powers intent detection in chatbots, sentiment analysis in customer feedback tools, and entity extraction in document processing systems.

A computing architecture loosely inspired by the human brain, consisting of layers of interconnected nodes (neurons) that process and transform data. Neural networks are the fundamental building block of modern deep learning systems, including large language models.

AI tools and platforms that allow non-developers to build AI-powered applications, automations, and workflows without writing any code. No-code AI tools like Zapier, Make, and Bubble have democratized AI implementation, enabling business owners and marketers to build sophisticated AI systems using visual drag-and-drop interfaces.

Google's AI-powered research and note-taking tool that lets you upload your own documents — PDFs, Google Docs, YouTube videos, websites — and then ask questions, get summaries, and generate audio overviews (podcasts) from your source material. Unlike general AI chatbots, NotebookLM only answers from the sources you provide, making it highly accurate for research and document analysis. The Audio Overview feature generates a realistic two-host podcast discussion of your material.

Notion's built-in AI assistant that helps users write, edit, summarize, translate, and brainstorm within the Notion workspace. Notion AI can generate first drafts, summarize long documents, extract action items from meeting notes, and answer questions about your Notion content.
