Harvard Student Creates AI That Makes Emails More Human

Tired of reading emails that sound like robots wrote them, Harvard Business School student Ben Horwitz created something completely unexpected. His new browser extension deliberately makes your writing messier, more casual, and wonderfully human.

The tool is called Sinceerly (yes, spelled wrong on purpose). It works like Grammarly in reverse, adding the kind of imperfections that prove an actual person cared enough to write the message themselves.

Horwitz, who also works as an investment partner at Dorm Room Fund, spent the past month building what he calls satirical commentary on our relationship with AI. "If we are using AI to write, then in this moment, can we use AI to un-AI our own writing?" he wondered.

The extension offers three levels of editing: subtle, human, or CEO. Each one transforms polished corporate speak into something real people might actually say.

The "subtle" option condenses wordy paragraphs and adds minor quirks. "Human" mode throws in slang, abbreviations, and casual phrasing. And "CEO" mode goes completely off script, mimicking the busy executive who's too important to worry about punctuation.

The Bright Side

Behind the satire lies a genuine insight about connection. As AI tools make everything look perfect, our little mistakes have become signatures of authenticity and care.

For people like the article's author who live with dyslexia, typos have long felt like professional liabilities. But Sinceerly flips that narrative, suggesting that imperfection might actually build trust in an age of artificial polish.

The misspelled name wasn't just branding. As a student, Horwitz appreciated that he could buy the domain cheap.

Sinceerly reminds us that being perfectly human beats being artificially perfect every time.
