Why use OnlineToolsPlus?

AI tools on OnlineToolsPlus use the Claude API — one of the most capable AI models available.

This gives you full control over cost and privacy while accessing professional-grade AI writing assistance.

Frequently asked questions

What types of scams can it detect?
Phishing emails, fake invoice scams, romance scams, lottery and prize scams, impersonation of banks or government agencies, advance fee fraud, tech support scams, and other common patterns.
How accurate is the detection?
The AI identifies common scam patterns and characteristics. It provides an assessment with reasoning rather than a definitive verdict. Novel or sophisticated scams may not always be caught. When in doubt, do not respond or click any links.
Does it need an API key?
Yes. A free Anthropic API key is required.
Can I paste the full email including headers?
Yes. More context produces better analysis. Include the full email text including the subject line and any visible headers.
What should I do if the tool identifies a scam?
Do not respond, click any links, or open any attachments. Report it to your email provider as phishing. If it impersonates a real company, report it to that company\'s fraud team.
Can it analyze text messages and WhatsApp messages?
Yes. Paste the message content and the tool analyzes it regardless of the original channel.
