Critic by Feyn

Critic is a tool for reviewing code written by AI coding agents, from Feyn, shown by its makers on 24 September 2026; the site footer names Chonkie, Inc. It installs as a plug-in for coding agents, which then write an account of each change as they make it: what changed, the assumptions made, the decisions taken, the parts that are complex, and evidence such as screenshots and instructions for running it. The reviewer reads that account alongside the code and can ask questions, which are answered by a fork of the original agent session — so the reviewer questions the context that produced the change rather than a fresh model guessing at it. Everything is also available over MCP, and changes pushed to GitHub are mirrored with GitHub’s permissions. No price is published. The problem it addresses is real for teams letting agents write a growing share of their code: review becomes the bottleneck, and a diff alone does not show why a change was made. The questions to ask before adopting it are where the agent’s session and the code are stored, and who can read them. It is listed as “Critic by Feyn” because several code-review tools use similar names.

Not yet independently verified: The launch date rests on the maker’s own launch post of 24 September 2026. The site publishes no price, its terms name no company (the site footer names Chonkie, Inc.), and no independent report of the product was found. We will update this when it can be confirmed, and remove this note.
