Hi Product Hunt 👋 I built LocalMark Studio because I wanted a Markdown editor that: works instantly doesn’t require an account doesn’t upload my notes anywhere still feels powerful and polished Most editors are either cloud-heavy or overly complex. LocalMark Studio focuses on local storage, performance, and a clean writing experience — while still giving you real folders, exports, and advanced Markdown features. Would love your feedback and feature ideas!

If someone already uses a common setup (Obsidian + sync, VS Code + Markdown preview, Typora, or Notion for drafting), what’s the clearest ‘switching moment’ where LocalMark Studio wins—what job does it do better enough that a user would change behavior?

Wow, LocalMark Studio looks amazing! The local-first storage and real file tree are exactly what Ive been searching for. How does the smart paste handle complex tables from websites?

Congrats on the launch! A local-first Markdown editor with this level of polish is really appealing. The focus on speed, privacy, and a real file tree makes it feel like a serious daily driver rather than a toy editor. Smart paste and scroll-synced preview are small details that make a big difference in real workflows. Curious if you’re planning any export or sync options while keeping the local-first philosophy intact.

Is IndexedDB reliable enough?
