There are 88 tools in this catalogue for writing, reviewing and explaining code. This guide is about how to narrow that down, not about which one is best — that depends on work only you can see.
What the catalogue actually holds
As of August 2026, the 88 listings in this category break down like this:
- 3 are free with no paid tier at all.
- 31 have a free tier alongside paid plans — worth checking what the free tier removes, because for several of them it is the thing you wanted.
- 54 are paid only, though most of those offer a trial.
Those numbers move. Tools in this space are launched and abandoned quickly, and every listing here is checked automatically for a site that still answers — the ones that stop answering are removed rather than left as dead links.
The mistake worth avoiding
Measuring autocomplete accuracy. The gain is not in typing faster; it is in the questions you no longer have to leave the editor to answer. A tool that is slightly worse at completion and much better at explaining an unfamiliar codebase usually wins.

What to check before you pay
Whether your code is used for training, and whether that can be turned off on your plan.
Two more that apply to everything in this category: what happens to your work if you stop paying, and whether there is an export that another tool can read. Both are answered on the vendor's own pages, and both are the questions people wish they had asked.

How this guide was put together
The counts come from the catalogue as this page was generated, and the descriptions come from each vendor's own published summary. Nothing here is a hands-on test: where a judgement is offered above, it is offered as a judgement. How the catalogue is built sets out what is checked and what is not.
