Live chat has become a crucial tool for businesses to improve customer experience and satisfaction. It allows for faster response times, better engagement with customers, and increased sales and revenue. Many companies are using live chat creatively across various industries such as social messaging, customer engagement, livestream, and custom chat applications. Some examples include Super, Decathlon, Guru, HubSpot, Discount Mugs, Bank of America, DripShop, Reddit, WIZZO, AskFirst, and UCAS. To implement live chat, businesses can choose from building a system from scratch, using a Chat-as-a-Service (CaaS), or using a Platform-as-a-Service (PaaS). Ably offers a flexible PaaS for realtime applications, including live chat experiences, with features such as Pub/Sub channels, emoji reactions, push notifications, authentication, and more.
