Choosing Your AI Tool
Cursor, Copilot, Claude Code, or a chat window? Pick a task and see which kind of tool actually fits it.
There is no single best AI coding tool, only the one that fits what you're doing right now. Pick a task below to see what fits.
Cursor
Your editor · Whole repo
An AI-first code editor that edits files directly and understands your whole project.
GitHub Copilot
Your editor · Open file + repo search
Autocomplete and a chat panel inside your existing editor, VS Code, JetBrains, and more.
Claude Code
Your terminal · Whole repo + can run commands
A command-line agent that reads your repo, runs tests, and makes multi-file changes on its own.
ChatGPT / Claude.ai
Your browser · Only what you paste
A chat window for quick questions or snippets, with no access to your files or terminal.
You don't have to pick one
Most vibe coders end up using more than one of these: a repo-aware editor or agent for the actual building, and a chat window on the side for quick questions that don't need any codebase context at all.
Picking wrong at this stage costs less than it feels like it does. Every one of these tools reads and writes ordinary text — a prompt, a diff, a file — so trying a second one later means an afternoon, not a migration. Treat the choice below as a starting point rather than a commitment.
- 1What does the task touch?
One function you can already see on screen, or files you would have to go find first? The second needs something repo-aware.
- 2How much do you trust the result before you look?
If you will read every line regardless, autocomplete is enough. If you want a full draft before you look, you need something that can act, not just suggest.
- 3Is this a one-off or a daily habit?
A single question does not justify installing anything. A workflow you will repeat every day justifies the setup cost.
Three jobs, not four products
The four tools above are not four points on the same scale. They do three different jobs, and the job determines what the tool needs to see and what it is allowed to do — which is the part that survives once the products themselves change name or get replaced.
Autocomplete-style
Predicts the next few lines as you type, using your open file and a little surrounding code. Fast, cheap, and blind to anything it was not already looking at.
Good for finishing a thought you have already started. Useless for a task that begins with “go find where X happens”.
Agentic editors and terminal agents
Can read your whole repo, edit multiple files, and run commands, then show you what changed. This is the category that can actually build a feature rather than complete a line.
The cost is trust: you are approving actions, not just text, and a command it runs is a command your machine ran.
Chat only
Sees nothing except what you paste into the box. No files, no commands, no memory of your project between sessions.
That is a limitation and a feature: the one category with nothing to configure, and the one where you decide exactly what it can see.
What a feature list won't tell you
Comparing tools by their feature list is a trap, because the feature list is the part that changes every few months. Two things about a tool matter more, and change slower: where your code actually goes, and how you pay for using it.
The other axis is how you pay. Some tools bundle usage into a flat subscription, so a slow, careful session costs the same as a fast one. Others meter by how much you actually send and receive, so a habit of pasting a whole file when a single function would do gets expensive in a way autocomplete never was. Neither model is wrong, but knowing which one you are on before you build a habit around it saves a surprise later.
Key takeaways
- The tools on this page are three jobs, not four points on one scale: autocomplete, agentic editing, and chat.
- Repo-aware tools earn their setup cost the moment the answer depends on code you did not write.
- A chat window is not a lesser tool — it is the right one for a question with no codebase context, and the one where you control exactly what it can see.
- Where your code goes and how you're billed for using it matter more, and change slower, than any single feature.
- Most people end up running two: one that edits, one that answers.
