Conversational UI

Rise of the Bots

Messaging apps have become ubiquitous and claim higher engagement with more monthly active users than the big four social networks. Frequently hyped as an answer to app fatigue, chatbots do not require your users to install a new app, and are often cheaper to build than traditional mobile applications.

Chatbot development

We have experience developing bots for all the major messaging platforms including Facebook Messenger, Slack, SMS, and voice interfaces such as Amazon Alexa. We can help you understand whether a conversational or menu-driven approach is right for your use case, how to design conversations, and how to apply AI and natural language processing technology.

Life is busy and getting busier. Sometimes technology is the problem, causing all kinds of distractions, but it can also be your friend. mindBot is a chatbot that uses introspective questioning and AI to help you organize your mind and concentrate on doing what matters most to you.

Initially developed as a Slack Application, Atchai have taken the Mindbot concept to every mobile device on the planet, integrating with Twilio's SMS service and Facebook Messenger. Working in short sprints, we suceeded in getting an MVP to market within 2 weeks, allowing us to start learning about user needs and continually iterate on the product.

Department of International Trade

We're working with the UK Government Department of International Trade to develop an innovative new conversational AI product. The laws around importing and exporting goods are complex, and cover everything from importing plans to exporting military hardware for repair. It can be extremely time consuming for the ordinary citizen or small business to understand whether they need a license, and if so which one.

By using a conversational user interface, we believe that we can reduce the time it takes to find these answers, as well as reducing the burden on human advisors.

LastSeen is a Facebook Messenger bot that asks the user to check-in once a day and notifies their designated contact if they don’t.

It was designed initially for older people living alone, providing them with a reminder that someone cares about them, and offering their children the security of knowing that their parents are safe.

LastSeen found more traction with a younger audience, especially young professional women living alone, students living away from home for the first time, and dog walkers!

What I like about working with Atchai is that they take the time at the beginning of the project to understand the big picture before choosing the right tech stack for the job.

What they delivered was cutting edge, very high quality software.

All work was delivered on time, on budget, to a very high standard with clear, honest communication throughout.
