Question: Is there a note-taking app that can convert my notes into executable code for rapid prototyping?

If you want a note-taking app that can transcribe your notes into executable code for rapid prototyping, Znote is a great option. The clever interface lets you turn plain notes into to-do lists and code blocks. It can handle Markdown and text files, and it can run short snippets of JavaScript, Bash or Shell code. Znote has a one-click deployment option so you can automate tasks and get work done faster. It's available for Windows, Mac and Linux, and it comes with templates and AI help to get you started.

Code Snippets AI is another impressive tool that uses multiple AI models to generate code in a chat interface. It supports multiple programming languages and can generate code, create documentation and refactor code. The system is designed to be easy to use and reusable, with end-to-end encryption to protect your code. It also comes with a free desktop app using open-source models and Pro plans for more features.

Although not a note-taking app per se, CodeAI could be useful for adding coding help to your workflow. The VS Code extension uses AI to help with code completion, unit tests and documentation. It supports multiple programming languages and prioritizes data security with end-to-end encryption. CodeAI offers a variety of pricing tiers so it's available to solo developers and teams.
