A LITTLE CONTEXT GOES A LONG WAY
NEW MESSAGE
To Your recipient

Hello,

Good thinking deserves clear words.
Here’s where mine came from.

Best,
Your name
Your role · Organization

Human reviewed — AI drafted; a human reviewed and approvedI reviewed it. I stand behind it.
The process is shared.
The responsibility stays.
SELF-DECLARED. NEVER A CERTIFICATION.
THE IDEA IS SIMPLE

AI can help with the words. Accountability stays with the sender.

01 / A shared language

Five ways to say
how it was made.

No scores. No hierarchy. Just a clear, voluntary declaration of the process behind a message.

These signals describe a process. They do not guarantee accuracy, quality, sincerity, or independent verification.

02 / Yours in a minute

A signature that feels like you.
With a little more context.

One small mark beneath your contact details. A clear declaration of how this message was made.

03 / The thinking behind the signal

Good writing
is good thinking.

The tools have changed.
The responsibility hasn’t.

Writing is how we organize ideas, consider consequences, and connect with another person. AI can help produce the words. It cannot accept responsibility on your behalf.

A human can write carelessly. AI can produce useful, carefully reviewed work. Trust grows through openness about the process, appropriate judgment, and ownership of the final message.

Outsource the mechanics.
Keep the judgment, integrity,
and accountability.
Read the philosophy

A process, not a promise.

“Human reviewed” means someone could evaluate, correct, or reject the message. “Governed AI” means defined controls were applied; those controls may be automated. Neither means independently certified.

04 / Put it into practice

Your next email.
A little more transparent.

Use the rendered signature in a desktop email editor, or copy the plain-text version anywhere.

01 Gmail

On the web, go to Settings → See all settings → General → Signature. Create a signature, paste the copied signature, set your defaults, and save. For mobile signature editors, use “Copy text”.

02 Microsoft Outlook

In new Outlook or Outlook on the web, open Settings → Accounts → Signatures. In classic Windows Outlook, use File → Options → Mail → Signatures. Paste the rendered signature and save. In Outlook mobile, use Settings → Signature and paste the text version; rich-signature support varies.

03 Apple Mail

On Mac, open Mail → Settings → Signatures. Select the account, create a signature, and paste. Disable “Always match my default message font” if you want to keep the formatting. Use the text version in mobile signature settings.

04 Images, privacy & portability

Text badges need no image hosting. This site also hosts PNG badges you can use. For PNGs, use a public HTTPS host or insert the downloaded PNG with your email editor. Keep the visible declaration text when images are blocked. Remote image hosts may receive normal HTTP requests; email signatures contain no tracking scripts or recipient IDs. Website visits are measured separately with Vercel Web Analytics.
