Frequently Asked Questions

Is EmoScan really free?

Yes, EmoScan is 100% free with no hidden tiers. There is no sign-up, no credit card and no daily cap on how many texts you can analyze. Every tool on the site works the same way: paste your text, get the emotional breakdown, close the tab if you like. We do not lock features behind a paywall or ask for an email before showing results, because the whole point is to make emotional intelligence available to anyone who needs it right now. 🎉

How does AI detect emotions in text?

The AI reads the same signals a perceptive person would, just faster and without bias. It weighs word choice, sentence structure, punctuation patterns and the surrounding context to work out what the writer actually feels. Short clipped sentences and a missing greeting often read as cold. Exclamation marks and intensifiers can signal excitement or anger depending on what surrounds them. The model was trained on millions of human-labeled examples, so it recognizes patterns like sarcasm, forced politeness or suppressed frustration that are easy to miss when you are emotionally involved in the conversation. 🧠

Which emotions can EmoScan detect?

EmoScan detects the six core emotions from Paul Ekman's research: joy, anger, sadness, fear, surprise and disgust. On top of those it identifies the harder social tones that cause most misunderstandings at work and in relationships, including passive-aggression, sarcasm, coldness, anxiety, defensiveness and forced enthusiasm. Instead of one label, you get a breakdown showing how strongly each emotion appears, so you can see when a message is mostly neutral with a thin edge of irritation, or when politeness is covering real frustration. 🎭

How accurate is the emotion analysis?

It is highly reliable for tone and overall sentiment, and it is especially good at catching things you cannot see when you are close to a conversation. That said, written text is missing tone of voice, facial expression and shared history, so no tool can be perfect. Inside jokes between friends, cultural differences in directness and very short messages are the hardest cases. Treat the result as a strong second opinion: if EmoScan says your email reads as cold, that is worth a rewrite, but you still know the relationship and context better than any model does. 🎯

Is my text stored or shared?

No. Your text is analyzed in the moment and is not stored on our servers, not attached to any profile and not shared with third parties. There is no account, so there is nothing to link your text to in the first place. Once you close the page, the analysis is gone. That matters because people paste genuinely sensitive things here: a message to an ex, a complaint about a manager, a resume they have not shown anyone. You should be able to check how something sounds without worrying about where it ends up. 🔒

Can I check if my message sounds rude before sending?

Yes, and it is one of the most popular reasons people use EmoScan. Paste your draft before sending and you will see whether it reads as cold, harsh, passive-aggressive or simply blunt in a way you did not intend. This is most useful for messages written while annoyed, tired or in a hurry, which is exactly when tone slips without you noticing. It also helps with cross-cultural and cross-generational communication, where a message that feels efficient to you can land as rude to someone else. If the result flags a problem, you can soften a phrase and re-check in seconds. ✉️
