Frequently Asked Questions
How accurate is the tone analysis?
Our AI provides confidence scores with each analysis. Longer, more detailed text typically yields more accurate results. The analysis is meant to be a helpful guide, and we recommend using your judgment alongside it.
Can it detect sarcasm?
Yes! Our analyzer can detect sarcasm and irony, though these are inherently difficult to identify in text. The context type you select helps improve accuracy for these nuanced tones.
What's the difference between tone and sentiment?
Sentiment is the overall positive/negative feeling (happy vs. unhappy). Tone is more specific—it tells you how something is expressed (frustrated, sarcastic, enthusiastic, etc.). We analyze both.
Why do context types matter?
Different communication channels have different norms. What's casual in a chat might seem unprofessional in an email. Selecting the right context helps our AI calibrate its analysis.
Can I analyze multiple messages at once?
Currently, the tool analyzes one text at a time for the most accurate results. For bulk analysis, you can run multiple analyses or consider our enterprise solutions.
