Paste any code snippet and get numbered pseudocode plus a ready-to-render Mermaid flowchart of the same logic.
Ready when you are
Paste a code snippet and hit generate to see plain-English pseudocode and a flowchart.
A pseudocode generator converts real source code into plain-English steps that describe the logic without language-specific syntax — useful for documentation, teaching, or explaining code to non-programmers.
Yes. Every result includes a Mermaid flowchart of the same logic, which you can copy and paste into mermaid.live (or any Mermaid-compatible renderer) to see the diagram.
Any mainstream language — the generator auto-detects the language from the code you paste, no need to specify it.
It works best on focused snippets and functions (up to 8,000 characters). For very large files, paste the specific function or block you want explained rather than the whole file.
