Hunt every em-dash
The single biggest tell. Replaced with a comma, period, or "and".
A Gmail tool that quietly pulls the AI fingerprints out of your drafts. Three styles. Your own key. Zero servers in between.
Open source. Built by @jaseem.
The single biggest tell. Replaced with a comma, period, or "and".
"I hope this finds you well." "Synergies." "Circling back." Gone.
CEO mode adds the kind of small typo a real thumb makes.
Compare the original draft with the cleaned version in real time. The slider shows how Subtle, Human, and CEO modes change tone, punctuation, and phrasing before you send anything.
Humanly is provider-agnostic by design. Bring your own key from the model family you already use, keep the rewrite local to your browser, and avoid introducing a new vendor into the email workflow.
The flow is intentionally simple: draft naturally, open the panel, choose a tone, review the highlights, and send. The page mirrors that sequence so search engines can extract the product story fast.
AI-first, finger-typed, voice memo. Doesn't matter. Humanly starts when you've got something to send.
The panel opens inside the compose window. Drag the slider between Subtle, Human, and CEO. Click Humanize.
Yellow highlights show every change. One click writes the rewrite back into your draft. You hit send.
Privacy is part of the product positioning, not a footnote. Keys stay local, drafts go directly to the provider over HTTPS, and the site now discloses analytics usage clearly in the page copy.

These answers are written for both visitors and crawlers: they are short, direct, and scoped to the things people usually ask before installing the extension.
Humanly runs inside Gmail, reads the draft in your browser, rewrites it with the model you choose, and writes the cleaner version back into the compose window.
No. The extension stores keys locally, sends requests directly to your provider over HTTPS, and does not use a backend or remote logging service.
Humanly supports Anthropic, OpenAI, Google, xAI, Groq, DeepSeek, Mistral, and OpenRouter, so you can use the provider you already trust.
This site explains where the project came from, why it exists, and how it differs from a typical AI email assistant: no account system, no backend, and no hidden data path.
A while back I came across Sinceerly by @ben and got hooked on the idea - a tiny tool that pulls the AI out of AI emails. I went to install it on Chrome.
The Web Store told me "this extension is not available on Chrome." I tried twice. Same answer.
So I built my own, in the same spirit and style, and open-sourced it. Bring your own key from any provider - Claude, GPT, Gemini, Grok, whatever. It runs locally. No servers. No accounts. About two seconds per rewrite.
Big thanks to @ben for the original idea. Go look at Sinceerly - it's gorgeous.
If something breaks or you have an idea, ping me on Instagram.
Installation is a standard unpacked extension flow. Download the release asset or repo ZIP, extract it, and load the folder in Chrome so the extension can run locally in the browser.
