How to choose an AI for coding

Popularity is a start, but the points below are where tools actually differ for this use case.

1. Inside your editor, or in a chat?

For autocomplete and multi-file edits, editor-integrated tools (GitHub Copilot, Cursor and the like) fit best. For design questions and debugging an error, an AI chat is usually enough.

2. How much code it can read at once

If you ask about large files or a whole repository, pick a model that supports file reading and handles long inputs.

3. API and usage-based pricing

If you build it into CI or internal tools, compare usage-based API prices rather than monthly plans. Estimating cost from token volume makes the differences clear.
