Free, No-Account, Hobby-Grade Cutlist Optimizer Mobile App To Replace The 5-Calculations-Per-Day Paywall Driving Woodworkers To ChatGPT

mobile app weekend hack •• multiple requests

On LumberJocks and FineWoodworking forums in 2026, hobbyists are openly using ChatGPT as a workaround because every popular cutlist optimizer (Cutlist Optimizer, OpenCutList, CutList Plus, SketchList3D) has either a 5-projects-saved limit, a 5-calculations-per-day limit, or a recurring subscription, and free options like Cutlist Evolution miss key features. Ship a no-account, no-subscription cutlist optimizer mobile app that handles standard sheet stock plus dimensional lumber and exports a printable PDF.

builder note

The honest moat here is principled refusal to monetize. If you ship a free app and it works, hobby woodworkers will tell every other hobby woodworker for free. Don't get cute with 'pro features' - just ship the calculator clean and let donations or affiliate links to lumber retailers cover hosting.

The cutlist-optimizer space is solved technically (it's bin-packing) but every commercial vendor has converted to recurring revenue, leaving a market for a deliberately-free, deliberately-mobile, deliberately-no-account app with optional Patreon/donation. The bar to beat is 'better than ChatGPT in a glove,' which is low.

Cutlist Optimizer (CutList Opt) Web-based, free tier gates calculations and project saves. New mobile app launched March 2025 retains the limits

OpenCutList (SketchUp extension) Free and open-source but requires SketchUp install and is famously picky about dimension precision (rejects 0.750364" pieces from being grouped with 3/4" pieces)

SketchList3D Full 3D woodworking software with cutlist as a feature; subscription-priced ($29/mo+), aimed at pros

Cutlist Evolution Free, no daily limits, but Windows-only desktop and dated UI; no mobile, no PDF export tuned for shop printers

ChatGPT (the workaround) Hobbyists actually using this in 2026 with hand-typed prompts; brittle, hallucinates dimensions, no kerf accounting, no waste optimization
