### 5/5 — 진짜 너무 좋움

*2026-07-18*

코덱스 어플보다 이게 좋은것 같아요. 
개발자님 제발 서버 추가 가능하게 해주세요 ㅠㅠ

맥으로 개발하고 서버로 운영중인데
두대 등록이 필요합니다ㅠㅠ 

지금은 1대만 등록 가능하고
꼭 QR말고 코드로만 등록도 가능하면 좋겠습니다. :)

### 1/5 — It’s good, but do not trust it

*2026-07-11*

Every time you change one feature our updated feature or fix something you need to do a full app test because I guarantee you will have new bugs that come up as a result of this so keep that in mind expect something to be broken whenever you use this to fix anything inside of your software

### 2/5 — qrcode

*2026-07-11*

i do not know how to pair my mac in terminal, since there are no qrcode displayed after i install npx-replay

### 5/5 — Better than OpenAI

*2026-07-01*

Codex experience is night and days difference! I’m greatful that this dude is killing it

### 1/5 — メインPCとモバイルを連携し辛い

*2026-06-28*

互換性、ログイン、紐図けが簡素化出来ていない。PC間でのリモート(遠隔操作に求められる認証が非常に使い勝手が劣悪)、何度、挑戦してもChatGPTと紐付けてもGitやTailscaleと連動させても全く使えないゴミアプリ。

### 5/5 — 2

*2026-06-24*

Finally! Love it.

### 5/5 — 이거 크네요.

*2026-06-23*

매우매우 감사합니다. 잘 쓸게요. 지속 업데이트 부탁드립니다.

### 5/5 — 공식앱보다 기능 많아 좋네요

*2026-06-22*

최고!

### 5/5 — this is by far the best app in the whole App Store

*2026-06-04*

but I guess only a fraction of mankind will ever experience

### 5/5 — ゲーム開発してる方に最適おすすめ生成AI！最高です

*2026-06-03*

⚠️忖度なしでレビューします

使いやすさ★★★★★
汎用性★★★★★
正確性★★★★☆

用途
・エラー潰し
・コード生成
・コード修正
・説明
etc...

まず、私はRobloxというゲームプラットフォームでの開発でluaUというマイナーな言語を用いて使用しましたが、問題なく動作し、従来の生成AIとは違い、細かく正確なコードを書いてくれるのでとても助かりました。
使っていて分かったのが生成AIにおける使い方について、プロンプトの重要性がかなり大事だと感じました。
使う人はプロンプトを細かく説明すればうまく使えます。とにかくプロンプトの細かさをうまく指定できるようになりましょう
