About KerfSense
KerfSense exists because woodworking plans deserve a tool that thinks in boards and joints — not in sketches that happen to look like furniture.
The standard
The best version of KerfSense should not feel like CAD. It should feel like a bench: grab a board, put it against another board, choose how they meet, see the joint settle, pull it apart, change the stock, watch the plan adjust, get the cut list, get the shop sheet.
KerfSense does not give advice. It states what is, and it tells you when something is impossible. Never "you should try this."
The format
Plans are .kerf files: plain, human-inspectable, versioned
documents. Compatibility is treated as a promise, not a feature — a file saved
by an earlier version of KerfSense keeps opening in every later one, carried
forward by explicit migration, never by luck.
The site's curated web demo reads the format with the same implementation the desktop app is built from — one source of truth, not a lookalike.
Where it runs
The KerfSense application is native to Windows, and built in Rust. The web
curated demo is the first cross-platform surface: one included
.kerf plan opens in the browser on any machine, nothing installed.
Opening your own plans is a later step.
The maker
KerfSense is made by Sacred Noir.
