What is sentiment analysis?

Sentiment analysis uses artificial intelligence to understand the sentiment or feeling behind some text. For example, if you come across a tweet and you don't know if its overall tone is positive or negative, we'll be able to tell you.

We offer two ways to get this information. If you are a developer, we offer an API endpoint to quickly identify the sentiment. If you would rather stick to Excel files, you can simply upload an Excel file and receive the same file back with our prediction added as new column.

Option 1: File Upload

Analyze the sentiment of your text data by simply uploading an Excel file.

Option 2: API

Analyze the sentiment of your text data by calling our API endpoint.

How to Get Started

We're offering use of our API tools for free. To get started, simply click the "Create Account" button on the navigation bar and complete the sign up.

If you want to use the file upload service, simply use the above button to take you there. Select your file, upload, and download the returned file when it's ready. If you're planning on using the API, click on Account -> API Key in the top-right of the navigation bar. Copy your key and use it in your API calls!

You can view your usage at any time by going to Account -> Quota. For the free tier, you can analyze 500 items per month. That's 500 API calls or uploading an Excel file with 500 rows of text. We hope you enjoy this service and we'd love to hear your feedback. If you would like to send us a note, feel free to email help@bielite.com. Cheers!
