Small tools that do one job well.
Amacy Works makes focused add-ons for Google Workspace and apps for Shopify. Each tool solves one everyday annoyance, loads fast, asks for as few permissions as possible, and has honest, flat pricing.
Apps
Heading Numbers & TOC Google Docs · coming soon
Add 1.2.3-style numbers to your headings (start from H1 or H2), renumber after every edit with one click, and keep your table of contents in sync.
Permissions: only the document you have open. We never read your other files.
More tools are on the way. Tell us what slows you down — that is how we decide what to build next.
How we build
- Minimal permissions. Our add-ons only touch the file you are working on.
- Your data stays yours. We do not sell data, show ads, or train AI models on your content.
- Flat, honest pricing. Prices are shown before you start. No per-order surprises.
- Maintained. When Google or Shopify changes something, we fix our tools. If we ever stop maintaining one, we will tell you in advance.
