📖 The AI Tool Bible

Coding

Pair programmers, autocompletes, and agentic code editors.

93 tools

Why it matters

Every developer is now an AI-assisted developer. The split is between in-line autocompletes, AI-first IDEs, and full agents that write commits and open PRs.

What's in here

Includes IDE-integrated pair programmers (Cursor, Copilot, Codeium), CLI/terminal agents (Aider), and full autonomous coding agents (Devin, Replit Agent).

How to pick

Pick an AI-first IDE (Cursor) for daily coding. Pick Copilot if you're standardised on JetBrains/VS Code already. Pick a coding agent (Devin, Replit Agent) for greenfield prototyping or ticket-grade work.
