From Perfect Grammar to ‘Anti Grammarly’: What Sinceerly Tries to Fix
For years, tools like Grammarly and polished AI email assistants have pushed us towards flawless, hyper‑formal writing. Now a Harvard Business School student, Ben Horwitz, is betting that people actually want the opposite. His Chrome extension, Sinceerly, deliberately introduces small mistakes and casual wording into emails so they sound less like AI and more like a rushed, real human. Horwitz announced the tool on X with the line, “I made the anti-Grammarly. Mess up your emails with AI,” explaining that he was “sick of everyone in my inbox sounding like AI.” Instead of correcting spelling and tightening tone, the Sinceerly email app leans into hesitation, inconsistency and mild clutter. In other words, it treats imperfection as a feature, not a bug — a striking contrast to traditional productivity tools built to remove every rough edge from our writing.
Why ‘Too AI’ Emails Make People Uneasy
Behind Sinceerly’s sudden virality is a wider anxiety: emails that sound “too AI” can feel cold, generic and suspicious. Malaysians using AI email assistants for job applications, scholarship appeals, or university emails worry that hiring managers and lecturers can spot template‑like phrases and overly polished paragraphs from a mile away. At the same time, AI detector tools that claim to separate human from machine writing are far from perfect. Independent tests show many detectors miss lightly paraphrased AI content and struggle with hybrid text that humans have edited, creating uncertainty about what will be flagged in academic or professional contexts. When both senders and recipients are second‑guessing what’s “real,” tone becomes a trust signal: a slightly messy sentence, a local expression, or an imperfect sign‑off can sometimes reassure readers that there is a person, not just a model, behind the message.
When Messier Emails Help — and When They Hurt
Sinceerly taps into a real desire for AI writing authenticity, but chaos has limits. In informal contexts — WhatsApp‑style emails to colleagues you already know, community group updates, or quick follow‑ups with long‑term clients — a looser, less polished tone can build warmth and relatability. Here, an anti Grammarly tool that softens stiffness might help you sound less robotic. But in high‑stakes situations common to Malaysian users, like job applications, government correspondence or legal documents, deliberate messiness can backfire badly. Recruiters still expect clear structure, correct names and coherent grammar. Universities and scholarship bodies may also use AI generated emails or essays as a red flag, even though detectors can be inconsistent. The risk isn’t just looking unprofessional; it’s signalling that you rely on gimmicks instead of genuine care and effort, especially when first impressions are formed through text alone.
How Sinceerly Works Differently from Grammarly and Standard AI Assistants
Traditional writing tools aim for accuracy, clarity and correctness. Grammarly flags grammar errors; typical AI email assistants draft entire messages that are clean, neutral and on‑brand. Sinceerly inverts that logic. Rather than smoothing out your writing, it uses AI to roughen it up, tweaking wording, tone and structure so it feels less like a model’s default output. While the exact mechanisms are not fully disclosed, the idea is simple: inject small imperfections so messages look more human at a glance. This flips the usual AI value proposition. Instead of promising error‑free language, the Sinceerly email app sells plausible human fallibility. It mirrors another emerging category of tools built to bypass AI detectors by mimicking human‑like variability — a reminder that as detection systems get smarter, some users respond by making their text strategically less perfect, not more.
Practical Tips for Malaysians: Blending AI Help with Your Own Voice
The healthiest approach for Malaysian professionals is not to blindly perfect or purposely wreck your writing, but to blend AI with your own voice. Use any AI email assistant for structure: outlining key points, fixing glaring grammar issues, or shortening long paragraphs. Then localise and personalise: add Malaysian English phrases you naturally use, greet people the way you normally would, and reference specific context that a generic model would not know. For sensitive situations — job applications, academic submissions, visa or financial aid emails — keep control by drafting the core message yourself and using AI only for light editing. If you experiment with an anti Grammarly tool like Sinceerly, reserve it for low‑risk, relationship‑building messages. Ultimately, trust grows when your emails sound consistently like you — clear, respectful and recognisably human, even if that includes the occasional typo.
