Pencilmind - A local-first workspace for visual thinking and planning

Hi everyone! 👋 Technical thinking often gets scattered across diagramming tools, documents, and task boards. Pencilmind brings them together in one calm workspace where you can map systems, document decisions, and turn ideas into next steps. Pencilmind combines visual canvases, structured notes, sequence diagrams, and lightweight boards. It is local-first: your workspace lives on your device in browser-backed SQLite, with an optional linked local-file backup. No account is required. This is the first public release, and I’d especially value feedback on the canvas workflow, local-first storage, and what would make Pencilmind more useful in your daily work. Thanks for taking a look!
