TextCaptcha Description
The TextCaptcha Service provides access to textual CAPTCHA problems via a simple JSON API or XML over HTTP.
The question is a textual challenge to be presented to the user. The answers are MD5 hashes for correct lowercased answers. You should be able check responses from real users that you challenge with a question against these checksums.
Text CAPTCHAs are more accessible to visually impaired people than image-based CAPTCHAs like ReCAPTCHA. Text is also more flexible, for example if you need to present a challenge via a text-only channel such as SMS or IRC.
The problem with text CAPTCHAs, is that they give inherently more information than an image distorted. They can be parsed, and under the right circumstances they are solvable. These simple logic puzzles are now easier to solve using Wolfram Alpha and other contextual parsing tools.

Yandex SmartCaptcha
The service filters out bots without affecting response time. We use ML models that are trained on datasets with data from many years of experience protecting Yandex's web resources. The datasets are updated regularly. The service generates images independently and does not use pre-made images. This allows it to maintain a human recognition rate of 85% while making it harder for bots to recognise the CAPTCHA. SmartCaptcha runs on the Yandex Cloud, which is compliant with international standards and Russian laws regarding information security. Verify your website without the "I am not a bot" button. Only users who make requests that look suspicious will see the invisible captcha. You can select the level of complexity for the texts that are generated by the service.

GeeTest
Traditional captcha distinguishes bots from legitimate users who have cognitive challenges. Machines are not able to recognize images or items. Humans are better at visual recognition tasks like item recognition and image recognition. Machine learning has made it possible for machines to perform these cognition tasks. Traditional CAPTCHA is too difficult to protect against sophisticated bot threats. This leads to high user friction, which in turn results in lower conversion rates. GeeTest created Slide CAPTCHA powered by AI in 2012 to solve the security vs user-experience problem. GeeTest developed an AI-powered Slide CAPTCHA in 2012 to replace the visual recognition challenge. This model was built using massive biometric data over the past 8 years. It is based on Graph Convolutional Networks. Our dynamic defense model, which analyzes over 200 parameters, gives you a deeper understanding of bot activities related to any API.
