Choose a coding assistant according to where you work and what you can verify. A tool that explains a function is different from an agent that edits a repository or a platform that publishes the app.
Match the tool to the job
| Work to finish | Starting point | What a person should check |
|---|---|---|
| Understand unfamiliar code | Claude or ChatGPT | The actual implementation and caller behavior |
| Make repository changes | Cursor or Devin Desktop | Diff scope, commands and regression checks |
| Work in the GitHub review process | GitHub Copilot | Permissions and independent review |
| Build a hosted prototype | Replit | Runtime costs, authentication and data handling |
A first workflow to try
Use a branch with a known starting state. Describe one bug with reproduction steps, expected behavior and a focused acceptance check. Ask for a short plan before changes. After the implementation, inspect the diff and execute the changed journey yourself; do not infer success from the agent’s summary.
Tools for this shortlist
- Cursor — A coding agent with desktop and terminal workflows for working in an existing software project.
- GitHub Copilot — AI coding assistance across supported editors, the terminal and GitHub, with agent and review workflows.
- Devin Desktop — The current Windsurf successor: an IDE and command center for coordinating coding agents.
- Replit — A browser-based platform for building and publishing apps with AI assistance and managed infrastructure.
- Claude — An AI assistant for document-led writing, analysis and code, with project context and collaborative artifacts.
- ChatGPT — A general AI assistant for drafting, revising, learning and working with files in a conversational workflow.
Before making it part of your routine
Keep generated work within the project’s conventions. Avoid granting production credentials for a local experiment. Review dependency changes and external network calls. If several agents work at once, identify who will integrate their patches and validate the combined behavior.
Frequently asked questions
Which tool is best for an existing project?
Compare repository context, editor support and review workflow using a real small change.
Can I skip tests when a build passes?
A build checks a different property from the user journey. Run the checks needed for the actual behavior.
What should I include in a prompt?
The goal, relevant context, constraints and the way success will be verified.
