Typos are back, baby
Be sinceerly human – AI to undo your AI writing
AI that adds typos to sound human sparks laughs and side‑eye
TLDR: Sinceerly is a Chrome plugin that uses AI to strip AI‑sounding phrases, kill em dashes, and sprinkle typos so emails feel human. Commenters split between calling it satire or clever tone‑tuning, while others warn it’s just better fakery—with many giggling at the deliberate “mistkaes” aesthetic.
An AI that “undoes” AI writing? The internet pounced. Sinceerly, a Chrome add‑on that kills em dashes, deletes roboty clichés like “not just…,” and even adds typos to make emails feel human, rolled in with big “Sent from my iPhone” energy and a cheeky “Humans make mistkaes.” Cue chaos.
One commenter nailed the vibe with “Sinceerily ironic,” while another begged this be satire, citing a founder blurb about cold‑emailing Fortune 500 CEOs and getting typo‑filled replies—one even calling him “Larry.” Supporters praised the vibe‑tuning idea: people want emails that sound like a person, not a PowerPoint. “I don’t hate this idea,” said one, arguing tone control should be a built‑in feature of chatbots. Another liked the name and icon but admitted they wouldn’t pay—relatable.
Then the ethics hammer dropped: is this just “better lying”? One voice warned AI tools increasingly help us fake authenticity—and adding typos to seem real feels like catfishing your inbox. Fans countered that everyone’s exhausted by “synergy” speak and this is a funny, useful band‑aid until models get better at personality.
Between the slider‑based “three levels,” the “Subtle Human CEO” sign‑off, and the Add to Chrome freebie, the crowd split into three camps: giggling at the meta joke, cautiously calling it clever tone control, and side‑eyeing the whole “humanify by typo” hustle. Internet, never change.
