Common questions
For basic sentiment (positive/negative), fastText is faster and free. For nuanced sentiment with context (e.g., sarcasm), expert.ai is better but costs a lot more. Most everyday users should start with fastText.
Not directly—fastText is a command-line tool and Python library. However, you can export a compressed model and run it inside a mobile app using a library like TensorFlow Lite. No ready-made mobile app exists.
Yes. expert.ai requires API integration using OAuth2.0, writing symbolic rules, and working with JSON. It's not a point-and-click tool—you'll need a developer or strong technical skills.
FastText is the better choice: it's free, fast, and you can train it on your own feedback data. expert.ai is overpriced and overcomplicated for a small business unless you have compliance needs.
Yes—fastText has pre-trained models for 157 languages and can identify languages automatically. It's one of its strongest features for multilingual text processing.
fastText wins for everyday users: it's free, fast, and practical; expert.ai is powerful but only makes sense for deep-pocketed enterprises.
If you're a regular person without a big budget or a dedicated tech team, start with fastText—it's free, fast, and you can learn it in an afternoon with a YouTube tutorial. Leave expert.ai for the corporate world where explainability and compliance justify the high cost.
