Import PowerPoint slides; slide titles, bullet hierarchies, and structure are automatically preserved.
Master desktop-grade keyboard navigation designed for frictionless writing speed.
Generate architecture flowcharts and sequence diagrams directly in text.
Full math typesetting for quantum mechanics and advanced engineering.
iℏ ∂/∂t Ψ(r,t) = [ -ℏ²/2m ∇² + V(r,t) ] Ψ(r,t)Web applications traditionally rely on cloud uploads or temporary file blobs. LocalMD bypasses server layers entirely by leveraging the native W3C File System Access API (`showOpenFilePicker`).
Once a file handle is granted, hitting `Ctrl+S` streams data directly back to disk through a `FileSystemWritableFileStream` at native disk read/write speeds, offering a desktop-class IDE experience inside the browser.
