AI tools for coding
AI coding tools ranked by fit: in-editor completion, agents that make multi-file changes, and terminal tools, with pricing and skill level for each.
AI coding tools sit on a line from suggestion to delegation. At one end, completion in your editor finishes the line you are typing. At the other, an agent reads the repository, plans a change across files, runs the tests and hands you a diff to review.
Which end suits you depends on how much you want to review versus write. Completion fits tight loops in code you know well. Agents pay off on larger, well-specified tasks, and ask for more care in review.

How these are ranked: Tools are ordered by the advisor's match score for this use case alone: no budget, skill level or other preference is assumed. Tell the advisor yours to get a personal top three.
What to check before you choose
- Whether it works in the editor or terminal you already use
- How usage is metered: flat, per request, or by tokens through your own API key
- What the vendor does with your code, and whether that can be switched off
- How it handles a large repository rather than a single file
