Additions to this list

1. GitHub Copilot Chat (Developer: Microsoft/GitHub) GitHub Copilot Chat goes beyond code completion — it is a full AI chat interface embedded in VS Code and GitHub.com that developers use to explain code, debug, write tests, and generate entire features in conversation. It is the most widely adopted AI coding assistant among professional developers and is critically missing from the development-focused list.

2. Amazon Q (Developer: Amazon/AWS) Amazon Q is AWS's enterprise AI assistant for developers and business users, capable of answering questions about AWS architecture, generating code, debugging, and connecting to internal data sources. It is a major enterprise player in the development-focused AI chat space.

3. Ollama (Developer: Ollama) Ollama enables developers to run large language models (LLaMA, Mistral, Gemma, DeepSeek, etc.) entirely locally on their own machines with a simple command-line interface and API. It has become the de facto standard tool for local LLM experimentation among developers and is extremely popular in the open-source community.
