ChatGPT has revolutionized how millions of people interact with AI. Launched by OpenAI in November 2022, it became the fastest-growing consumer application in history, reaching 100 million users in just two months. At its core, ChatGPT is a conversational AI assistant powered by GPT-4, capable of understanding context, generating human-like responses, writing code in dozens of programming languages, explaining complex concepts, and helping with creative writing. The interface is refreshingly simple - just type your question and get an answer. Key features include: multi-turn conversations that remember context, code generation and debugging, document analysis, image understanding (GPT-4 Vision), custom GPTs for specific tasks, and voice conversation. The free tier provides access to GPT-3.5, while ChatGPT Plus ($20/month) unlocks GPT-4, DALL-E, and advanced data analysis. For developers, ChatGPT excels at explaining unfamiliar code, generating boilerplate, writing unit tests, and suggesting architectural improvements. It's become an indispensable tool in modern software engineering workflows.

Claude is Anthropic's AI assistant, widely considered one of the most capable AI models available today. Created by a team of former OpenAI researchers focused on AI safety, Claude offers thoughtful, nuanced responses with a distinctive writing style. What sets Claude apart is its impressive 200,000+ token context window - large enough to process entire books, complete codebases, or multi-hour meeting transcripts in a single conversation. This makes it especially valuable for tasks requiring deep analysis of long documents. Strengths include: exceptional reasoning on complex problems, nuanced creative writing, strong coding abilities (especially for refactoring and architecture), honest acknowledgment of uncertainty, and helpful responses that don't dumb things down. Many developers prefer Claude for tasks like code review of large pull requests, analyzing technical documentation, writing detailed technical content, and working through complex debugging scenarios. The Artifacts feature lets Claude build interactive previews of code, documents, and websites directly in the chat.

Midjourney is widely regarded as producing the most artistic and visually stunning AI-generated images available today. Unlike other image generators, Midjourney was designed from the ground up with an aesthetic sensibility - its outputs have a distinctive beauty that other models struggle to match. The platform is unique in being Discord-first: you interact with Midjourney by joining their Discord server and typing commands like `/imagine dreamy anime sunset over Tokyo`. This creates a community aspect where you can see other users' prompts and learn techniques. Version 6 brought substantial improvements: better text rendering within images, more photorealistic results, improved hand and face generation, and finer control over composition and style. Use cases include: concept art for games and films, marketing imagery, album covers, book illustrations, UI mockup inspiration, storyboards, and personal art projects. Pricing starts at $10/month for basic usage.

GitHub Copilot transforms the coding experience by providing AI-powered code suggestions as you type. Developed by GitHub and OpenAI, it's trained on billions of lines of public code and understands context across multiple files. Beyond simple autocomplete, Copilot can generate entire functions from comments, write unit tests for your code, translate code between languages, explain unfamiliar code, and suggest refactoring improvements. The newest Copilot Chat brings ChatGPT-style conversations directly into your IDE. Supported editors: VS Code, JetBrains IDEs (IntelliJ, PyCharm, WebStorm, etc.), Vim/Neovim, and GitHub.com. It works with virtually every programming language, including less common ones. Pricing: $10/month for individuals, $19/user/month for businesses with additional security features, and free for verified students and open-source maintainers. Most developers report meaningful productivity improvements after the initial adjustment period.

Figma has become the undisputed standard for interface design, replacing tools like Sketch and Adobe XD in most modern design workflows. Its browser-based nature and real-time collaboration features make it perfect for distributed teams. Core strengths include: real-time multiplayer editing (like Google Docs for design), an extensive plugin ecosystem, auto-layout for responsive design, component libraries and design systems, prototyping with interactive transitions, developer handoff with code specifications, and version history. Figma's free tier is generous (unlimited personal files, 3 team projects). Professional ($15/month) adds unlimited team projects. Organization ($45/user/month) adds enterprise features like branching, shared libraries, and SSO. Beyond design, Figma has expanded into FigJam (whiteboarding), Dev Mode (code-focused view), and Slides (presentation tool). Adobe attempted to acquire Figma for $20B in 2022, though regulatory issues ultimately blocked the deal.

GitHub is the world's largest platform for version-controlled code collaboration, hosting over 420 million repositories and serving 100 million+ developers. Originally a git hosting service, it has evolved into a comprehensive platform for the entire software development lifecycle. Core features: git repositories with pull request workflow, issue tracking and project boards, GitHub Actions for CI/CD automation, Codespaces for cloud-based development environments, Copilot for AI-assisted coding, Pages for static site hosting, and Packages for package registry. GitHub is home to most of the world's open-source software - everything from Linux to Kubernetes, React to TensorFlow, Python to Node.js. It has become the de facto resume for developers, with your GitHub profile often mattering more than a traditional CV. Microsoft acquired GitHub for $7.5 billion in 2018, though it continues to operate independently. Free tier includes unlimited public and private repositories. Teams ($4/user/month) adds advanced permissions. Enterprise ($21/user/month) adds SAML, audit logs, and advanced security.

Stack Overflow has been the essential programmer's Q&A resource since 2008. With over 50 million monthly visits and 20+ million registered developers, it's where programming questions get answered by peers. The unique community-driven format rewards well-researched questions and accurate, detailed answers through reputation points and badges. High-quality answers often include multiple approaches, edge cases, and references to official documentation. While AI assistants like ChatGPT have impacted traffic, Stack Overflow remains invaluable for: obscure error messages, language-specific quirks, deep technical discussions, architectural debates, and historical context on why certain solutions work. The community's fact-checking often catches errors that AI confidently presents. Beyond the main site, Stack Overflow for Teams provides private Q&A for companies, and the broader Stack Exchange network covers dozens of technical fields including DevOps, SysAdmin, and Web Apps.
