COLLATERAL SYSTEM 10 / 12
Letterhead & signature generators
Two small browser tools so the team never rebuilds a letterhead or a signature by hand.
Fill the form, watch the preview, print or copy. Both tools run offline in a single file and follow the brand rules without being asked.
THE OUTPUT / GENERATED FOR APEX INSTRUMENTS
What it makes.
Two single-file tools: a letterhead writer and a signature builder.
Apex Instruments, Northlight Group, and every name, price, and contact in these files are fictional demo data. The real versions of this system run inside client systems and are not shown.
THE MECHANISM / SHOW THE SHAPE, NOT THE SOURCE
How it is made.
- 01Ask
Ask for a generator, name the fields the team needs.
- 02Recipe
The tool skill fixes the layout: form on the left, live preview on the right, print or copy on the button.
- 03Assemble
One HTML file with inline CSS and JS. No build step, no server, no dependencies.
- 04Check
The preview is tested by typing into each field. Print output is measured at 8.5 x 11. Copy buttons are exercised.
- 05Ship
Two files the team can open from any folder.
WHAT IT READS
- Sender details
- Brand tokens
- Signature rules
- Letter page geometry
WHAT IT CHECKS BEFORE IT SHIPS
- Works offline from a single file
- Print hides the form and prints the page
- Signature copies as HTML and as rich text
- Brand rules visible in the tool
Counts only. Client and partner names, source files, and internal wording stay private. Every example on this page was regenerated for the fictional company rather than de-branded from client work.
