Back to the toolCan I analyze many reviews at once?

What is sentiment analysis?
Sentiment analysis uses AI to decide whether a text expresses a positive, negative or neutral opinion. Businesses use it to understand reviews, comments and feedback.
How accurate is it?
The English model is trained on movie and product reviews and is usually above 90% accurate on clear opinions. Sarcasm, mixed opinions and very short texts are harder.
Does it work with Urdu or Roman Urdu?
The models are trained mainly on English and European languages, so results for Urdu and Roman Urdu are less reliable.
Can I analyze many reviews at once?
Yes. Turn on “One per line”, paste up to 500 lines and export the results as CSV.
Is my text uploaded?
No. The AI runs in your browser and your text stays on your device.
