Cordbook
The firewood seller's yard ledger — cord math, seasoning dates, moisture proof and the customer book
Measure a stack and Cordbook turns length × width × height into full and face cords, counts it down to honestly seasoned by species, logs moisture-meter readings against the 20% line, keeps every buyer and delivery by Jul–Jun season, and tells you whether the winter paid. Free, no install.

What you can do in Cordbook on the web
Cord math on the spot
Type a stack's dimensions or tap a preset (8 ft rack, 4×8 face-cord rack, pallet stack, level or heaped pickup bed) and get full cords, face cords and a quote at your price.
Seasoning board by species
Red oak 24 months, hickory 18, maple/cherry/birch/mixed 12, ash and pine 8 — every stack gets a ready date, a progress bar and a countdown; ready stacks are pinned under SELL THESE.
Moisture log with the 20% line
Log meter readings per stack and watch the hard-edged trend fall toward the dashed seasoned line — dated proof for a skeptical buyer.
Customer book and reorder list
Name, phone (tap to text or call), address, yard notes and full delivery history; the REORDER LIST surfaces everyone whose last load was 9–15 months ago.
Delivery ledger and receipts
Log loads in cords or face cords against a buyer and a source stack (which subtracts from the pile), track paid vs owed, and download or copy a clean receipt.
Season summary
Fuel, chains and bar oil, equipment, bought log loads and other expenses roll up with sales into cords sold, revenue, expenses and net for any July-to-June season.

Questions
Is the web version of Cordbook free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Cordbook iPhone app?+
Receipts download as text or copy to the clipboard instead of rendering as a PDF share sheet. Tap-to-text and tap-to-call open your device's messaging or phone app only where the browser supports sms: and tel: links. Data lives in this browser only; export a JSON backup to move it to another device.
