Founder story
I built Code Diary because I needed it.
I built Code Diary because I wanted dedicated places for the commands I use. Instead of searching old chats or notes, I could open the app, click copy, and use the command in my terminal.
As the diary grew, I noticed something more valuable: once I saved a solved issue with its context, I did not need to solve it again. The app became a practical memory for the work that is easy to forget but expensive to repeat.
I am now building Code Diary in public through Ambryonic. Sharing the releases, lessons, and decisions helps the product reach more developers and gives me the feedback needed to make it genuinely useful beyond my own workflow.
