How can I tell if an email was written by AI?

Paste the email body into Plagly. The engine scores each sentence for statistical patterns associated with models like ChatGPT and Copilot, then highlights AI-generated lines with confidence scores so you can judge the message's origin.

Does it work on short emails?

Emails of roughly 80-100 words or more give the most reliable results. Very short one-line messages may not carry enough signal for a confident verdict.

Can it detect AI-generated cold outreach and sales emails?

Yes. Automated sales and outreach emails are a common use case. Plagly flags the AI-generated body text while leaving standard templated elements unmarked, helping you identify mass-produced outreach.

Will normal business phrasing be falsely flagged as AI?

No. Plagly is calibrated for email conventions and detects AI writing patterns, not formality. Standard professional phrasing written by a human is not flagged.

Is the email checker free?

Yes. Quick email scans are completely free with no signup. Document upload and batch analysis are available with a free account.

Why Check Your Email for AI Content?

AI now drafts a large share of professional and outbound email, from sales outreach to customer support replies. Plagly.ai's Email AI Checker lets recruiters, sales teams, and individuals verify whether an email was written by a human or generated by ChatGPT, Microsoft Copilot, Gemini, or another model. Email is a difficult format for naive detectors because messages are short and follow conventional templates; our engine is calibrated to recognize genuinely AI-generated phrasing while leaving standard greetings, sign-offs, and boilerplate unflagged, holding the false-positive rate below 0.4%. Paste the email body for an instant, sentence-level analysis showing which lines carry AI patterns — useful for spotting automated outreach, vetting candidate communications, or confirming that your own AI-assisted draft sounds human.
