Letz - Lucy

Letz was the world's first active multi-platform productivity chatbot. Our bot, Lucy, functioned as a virtual assistant. People could set tasks, ask questions, and the bot studied people’s behavior and even sent funny jokes upon request. It provides Artificial Intelligence to empower professional productivity for individuals.
As an innovative company, we developed our proprietary AI tech based on Recurrent Neural Networks and machine learning that gave the bot a personality and a human touch in the interaction. Additionally, we developed our own NLP technology that was specially designed to significantly boost the accuracy, fluency, and speed of text entry on mobile and computing devices also making it possible for the bot to learn new languages fast without a vast amount of data. She could make you laugh, entertain you, inform you at any time about the weather and world news but also encourage you to be very productive. She was a friend.
Letz was the first and only EU startup that won the prestigious Product Hunt – product of the year award. We won the award competing side by side with Google, Slack, and Product Hunt.


Slavcho, the chatbot assistant helps the users through the process of choosing the most suitable smartphone for themselves.
The main purpose of this chatbot is to give users a phone recommendation based on their discussed preferences. Slavcho transforms for what is today a cumbersome and a tiresome process into a pleasant and simple experience for the users.
The chatbot gathers preferences to find out which smartphone will suit the user the most according to the user’s needs and capabilities. The chatbot chooses the best recommendations for the users with the help of a built recommendation system.
Slavcho gathers the information in an interesting and fun way as he doesn’t ask direct questions for the phone specifications, but he tries to find out how the user will utilize the smartphone instead. This way the chatbot gets more genuine answers and can form a more accurate list of suggestions.
The chatbot works on a back-end server with the machine learning modules which are responsible for composing the next message that the chatbot replies to the user. An AI model is also trained with certain information about general knowledge and everyday type of conversation. The content engine is responsible for the logic of how the chatbot responds to the messages from the user. This includes the expert system and natural language processing (NLP). The interesting part is that the NLP technology was used for a bot that uses the Macedonian language for communication, which was really challenging due to the fact that there are not many resources, data, and tools that use this language and lettering. The chatbot understands the Macedonian language, both Cyrillic and Latin lettering.
With these capabilities of the chatbot, the users will get reliable answers to their questions and the best recommendation for smartphones according to their own preferences.
