Three tools · Zero uploads · One tab each

Every post starts as a file. these are the tools that shape it

A Markdown reader for whole folders of docs, a split-pane HTML editor with click-to-edit visual mode, and an SVG inspector that pans, zooms, exports PNG, and turns Mermaid into clean vector diagrams.

No accounts. No uploads. No telemetry.
Every tool runs entirely in your browser —
your files never leave your machine.

HTML Editor

Split-pane editing with a live rendered preview

Syntax-highlighted code on the left, the rendered page on the right — or flip to visual mode and edit the text in place. Tabs for multiple files, find & replace, word wrap, and ⌘S saves straight back to an .html file.

SVG Viewer

Pan, zoom, play, export — and generate from Mermaid

Drop in any SVG to inspect it against checkerboard or solid backgrounds, scrub the source, pause and restart SMIL/CSS animations, and export crisp PNGs at 1–4×. A built-in Mermaid panel turns diagram syntax into downloadable vectors.
