Description

Perplexity answers complex questions with cited web sources and AI-native search.

GitHub Copilot transforms the developer experience by providing contextualized AI assistance throughout the software development lifecycle, from inline code suggestions and chat in the IDE to automated code reviews and vulnerability fixes.

Key features

• Source diversity
• Audio brief

• Inline code suggestions
• IDE chat assistance
• Agent mode for autonomous background execution
• Copilot Autofix for vulnerability remediation
• Copilot code reviews on pull requests
• Multiple LLM options for speed, accuracy, or cost
• Custom agent and MCP tool integration
• Command Line Interface (CLI) support

Pros

• Real-time web search grounding
• Citations to sources
• Choice of LLMs on Pro
• Focus modes (academic, Reddit, etc.)
• Threads keep context
• Deep-research Copilot
• Native mobile apps
• Sonar developer API

• Offers a completely free tier with basic code completions and chat limitations.
• Provides free verified student, faculty, and open-source maintainer plans.
• Integrates natively with major IDEs like VS Code, Visual Studio, JetBrains, Vim, and Neovim.
• Ensures Copilot Business and Enterprise subscriber data is never used to train GitHub models.
• Includes an autonomous agent mode to plan, explore, and execute tasks across multiple files.
• Allows users to switch between multiple leading LLMs optimized for cost, speed, or accuracy.
• Enables Copilot code reviews for pull requests on github.com across entire organizations.
• Helps developers locate and remedy security vulnerabilities automatically with Copilot Autofix.

Cons

• Free tier has query limits
• Citations sometimes mismatched
• Less conversational depth than ChatGPT
• Best models gated to Pro
• Occasional hallucinations
• Search bias toward popular sources
• Limited customization
• No file training

• Free plan users are restricted to 2,000 completions and 50 chat requests.
• Individual plan subscriber data (Free/Pro/Pro+) may be used to train models unless users manually opt out.
• Chat functionality is not supported directly in vim, neovim, or Azure Data Studio IDE extensions.
• Coding suggestions may be less robust or frequent for languages with low public repository representation.
• Enabling pull request code reviews for non-licensed users incurs additional organization metered charges via AI credits.
