About

In complex environments, memory is a liability. The Checklist Generator is engineered to mitigate cognitive load and prevent failure in high-stakes processes. Unlike basic to-do apps, this tool treats checklists as hierarchical documents - Standard Operating Procedures (SOPs) - where accuracy is paramount. It is designed for developers deploying code, pilots verifying flight readiness, and project managers overseeing critical paths.

Why use this tool?

Zero Latency: Runs entirely in the browser (Client-Side). No database round-trips.
Data Sovereignty: Your data is stored in localStorage. It never leaves your device.
Structure: Supports deep nesting (parent-child relationships) to map complex logic.
Portability: Instant export to Markdown (for GitHub/Obsidian) or JSON (for API integration).

We utilize a flat-file database structure rendered virtually to ensure performance even with lists exceeding 1000 items.

Formulas

To calculate the effective completion of a hierarchical task list, we use a weighted progression formula. Simple counting is insufficient for nested SOPs. The Weighted Progress W is calculated as:

W = N∑i=1 w_i ⋅ s_iW_total

Where w_i represents the complexity weight of the item (based on indentation level d) and s_i is the boolean state (1 for complete, 0 for incomplete). The weight decays as nesting deepens:

w_i = 1d + 1

Frequently Asked Questions

We prioritize keyboard accessibility and speed. Use the "Up" and "Down" arrows to reorder tasks. Use the "Indent" (Right Arrow icon) to turn a task into a sub-task of the item above it. Use "Outdent" (Left Arrow icon) to move it back up the hierarchy. On desktop, standard Tab/Shift+Tab navigation is preserved for accessibility.

Yes. This tool follows a "Local-First" architecture. Your checklist is serialized into a JSON string and stored in your browser's LocalStorage. No data is transmitted to our servers. If you clear your browser cache, the data will be lost, so we recommend using the "Export JSON" feature for backups.

Absolutely. Click the "Copy Markdown" button. The output is formatted specifically for GitHub Flavored Markdown (GFM). You can paste it directly into PR descriptions, Issues, or Readme files, and GitHub will render interactive checkboxes.

The "Clear All" button requires a double-confirmation (browser prompt). However, individual item deletions are immediate. We recommend regularly exporting your list if you are working on a critical long-term document.

We have pre-loaded over 50 industry-standard templates. When you select a template, the system parses the stored JSON structure and hydrates the DOM. You can then edit these templates and save them as your own current state. We do not currently support saving multiple custom templates in the browser, but you can save them as JSON files on your computer and reload them later.
