AI has fundamentally changed phishing. In 2023, you could often spot a phishing email by its broken grammar, awkward phrasing, and generic templates. In 2026, AI-generated phishing emails are grammatically perfect, contextually relevant, and personalized to the recipient. Security firm SlashNext reported a 1,265% increase in phishing emails since the mainstream release of generative AI tools, and the average time to create a convincing phishing campaign has dropped from hours to minutes.
What Has Changed
Grammar Is No Longer a Red Flag
The most commonly taught phishing indicator — "look for spelling and grammar mistakes" — is becoming obsolete. AI-generated text is grammatically flawless. Scammers in any country, speaking any language, can now produce native-quality English emails. This does not mean grammar-based detection is useless (many low-effort scams still have errors), but you can no longer rely on it as a primary indicator.
Personalization at Scale
AI enables scammers to personalize emails using data scraped from social media, data breaches, and public records. An AI-generated phishing email might reference your real employer, a recent LinkedIn post, or a conference you attended. This level of personalization was previously only possible in targeted spear-phishing attacks. Now it can be automated across millions of emails.
Convincing Impersonation
AI can mimic writing styles. Given examples of how a company communicates, it can generate emails that match the tone, formatting, and vocabulary of legitimate corporate communications. This makes brand impersonation significantly more effective.

Detection Strategies That Still Work
AI-generated text may be harder to spot, but the fundamentals of phishing have not changed. The email still needs you to take an action, and that action is what you should scrutinize:
1. Verify the Sender Domain
No matter how perfect the email text is, the sender address must still come from the company's real domain. AI cannot change the "From" address in a way that passes email authentication (SPF, DKIM, DMARC). Check the full sender address — not just the display name.
2. Inspect the Links
The destination URL is the single most reliable technical indicator. AI-generated text can be flawless, but the phishing link still points to a domain the scammer controls. Hover over every link and verify the domain matches the company's actual website.
3. Question the Request
What does the email want you to do? Click a link? Download an attachment? Reply with information? Call a number? Every phishing email requires action from you. If the requested action involves credentials, payment, or personal information, verify through a separate channel — go directly to the company's website or call them.
4. Use AI to Fight AI
If scammers use AI to create phishing emails, defense must use AI to detect them. IsThisAScam.to uses AI analysis specifically trained to detect manipulation patterns, regardless of how well-written the text is. The tool identifies urgency cues, social engineering techniques, and request patterns that are inherent to phishing — features that persist even in AI-generated messages.
5. Check Through Official Channels
This remains the gold standard: if you receive an email about your account, go directly to the company's website (type the URL yourself) and check your account. If the email is legitimate, you will see the same information in your account. If it is phishing, there will be nothing there.
AI Voice Phishing (Vishing)
The threat extends beyond email. AI voice cloning can now replicate a person's voice from just a few seconds of audio. Scammers use cloned voices of executives for business email compromise (BEC) attacks, and cloned voices of family members for emergency scams ("Grandma, I'm in trouble and need money"). If you receive an unexpected call from someone asking for money or information, hang up and call them back on a number you know is real.
The Arms Race Ahead
AI phishing will continue to improve. The defenses that matter most are behavioral, not technical:
- Never click links in emails when you can go directly to the website
- Never provide information in response to an incoming request — verify first
- Use a scam detection tool as a second opinion on any message you are uncertain about
- Enable multi-factor authentication on all important accounts — even if credentials are stolen, the attacker cannot log in without the second factor
