WhatTheDiff
WhatTheDiff is an AI-powered code review assistant that automatically generates pull request descriptions, provides inline code refactoring suggestions, and sends summarised notifications to keep both technical and non-technical stakeholders informed about code changes. The tool integrates with GitHub and GitLab, translating technical changes into plain language for wider team communication.
ChatGPT
ChatGPT is OpenAI's flagship conversational AI on web, mobile, and desktop. It covers writing, coding, research, image/video, voice, and agentic work. As of late 2026, paid Work and Codex surfaces expose the GPT-6 family (including GPT-6.1 Sol), while Pro/Business Premium users in eligible markets get OpenAI Dots: always-on agents with their own cloud computer.
Claude
Claude is Anthropic's AI assistant for nuanced writing, long-context reasoning, and coding via Claude Code. The Claude 5.5 family (including Sonnet 5.5, launched September 28, 2026) is the current default for fast, cost-efficient professional and coding work on claude.ai and the Claude API.
Gemini
Gemini is Google's multimodal AI assistant and model family across the Gemini app, AI Mode in Search, AI Studio, and the Gemini API. As of October 2026 the frontier flagship is Gemini 4 Argon (paid API / Pro+Ultra surfaces); Flash-class models remain the cheaper workhorse for high-volume agents.
Cursor Ai
Cursor is an AI-native code editor (VS Code fork) for software developers. Agent mode plans and edits across your repo with frontier models (GPT, Claude, Gemini, and others). Tab completions stay unlimited on paid plans; agent and premium model use is metered. Use Cursor when you want full-repo context inside the editor. Prefer GitHub Copilot when PR review and GitHub-native seats matter more. Many teams run both.
Windsurf
Windsurf is an AI-powered code editor (a VS Code fork) developed by Codeium. Its headline feature is Cascade, an AI agent that handles multi-file editing, planning, code generation, and terminal command execution. Positioned as a lower-cost alternative to Cursor, Windsurf offers unlimited autocomplete on the free tier and a flat $20/month Pro plan (vs. Cursor's variable pricing that can reach $35–60/month for heavy users).
