Anthropic's AI assistant — exceptionally good at writing, analysis, and coding with a 200K context window.
Claude is Anthropic's flagship AI assistant, known for producing nuanced, thoughtful responses and handling extremely long documents with its 200,000-token context window. It excels at writing, summarizing, coding, and in-depth analysis, and consistently scores at the top of reasoning benchmarks. Claude is designed with safety and honesty as core principles. The free tier gives access to Claude 3.5 Sonnet with daily message limits. The Pro plan unlocks higher usage, priority access during peak times, and access to the latest models including Claude 3 Opus. Projects let you give Claude persistent context and uploaded files to work from across sessions.
OpenAI's AI assistant — the tool that started the AI revolution, now with image generation, voice, and browsing.
ChatGPT is OpenAI's consumer AI product and the most widely used AI assistant in the world. It runs on GPT-4o, which handles text, images, audio, and video inputs, and integrates DALL-E 3 for image generation directly in the chat. The free tier is generous; Plus unlocks faster responses, higher limits, and access to the full GPT-4o model. Custom GPTs let you build specialized assistants with specific instructions and knowledge bases. The Pro plan ($200/mo) adds unlimited access and o1 pro mode — OpenAI's most capable reasoning model — making it the go-to for researchers and power users who need maximum throughput.
The AI-first code editor taking on VS Code with powerful multi-file editing
Cursor is an AI-first code editor built on VS Code. Unlike Copilot (a plugin), Cursor is the entire editor — which allows it to have deeper AI integration. Its standout features are multi-file editing (Composer), codebase chat (ask questions about your entire repo), and the ability to apply AI edits across multiple files at once.
The most widely used AI code assistant, built by GitHub and OpenAI
GitHub Copilot is the industry-standard AI coding assistant, used by millions of developers. It integrates seamlessly with VS Code, JetBrains IDEs, and more, providing inline code suggestions, multi-line completions, and a chat interface. Copilot Chat can explain code, generate tests, and answer coding questions directly in your editor.
Google's AI assistant — deeply integrated with Google Workspace, Search, and the broadest multimodal capabilities.
Gemini is Google's AI assistant, powered by the Gemini 2.0 family of models. It stands out for its native integration with Gmail, Google Docs, Sheets, Drive, and Search — making it the natural choice for anyone already in the Google ecosystem. Gemini Advanced (included in Google One AI Premium) gives access to Gemini Ultra, the most capable model, plus deep Workspace integration through Gemini for Workspace. Gemini 1.5 Pro supports a 1 million token context window — the longest of any major AI assistant — enabling it to process entire codebases, books, or hours of video. Its multimodal capabilities include native image, audio, and video understanding.
Ultra-fast AI code editing model that generates code at 1,000+ tokens per second.
Mercury Edit is a diffusion-based language model from Inception Labs built specifically for code editing. Unlike autoregressive models, it generates entire code blocks in parallel — achieving speeds of 1,000+ tokens per second, which is 5× faster than comparable GPT-class models. This makes it particularly well-suited for IDE autocomplete, fill-in-the-middle completions, and next-edit prediction. It is OpenAI API-compatible, meaning it works as a drop-in replacement in any IDE or toolchain that supports the OpenAI format. Mercury Edit is available on AWS Bedrock and Azure AI Foundry, with 10 million complimentary tokens for new accounts.
AI code assistant built for enterprise privacy and security
Tabnine is an AI code completion tool with a strong focus on privacy and enterprise security. It can run entirely on-premises (air-gapped), uses code only within your organization, and never trains on your code. For teams with strict compliance requirements (finance, healthcare, government), Tabnine is often the go-to choice.
