Every GoodBarber feature, in plain sight

In Structure, the "Add a section" button opens a window that starts with a question: "What do you want to add?". Below it, the list gathers everything GoodBarber can add to an app, grouped by what each entry does to it: what adds a section, what fills a section from a service you already use, what works in the background without adding a screen, and what enriches a section already in place. Ideas to build with the AI Extension Builder have a group of their own.

Find answers in podcasts with GoodBarber Chatbot

Take a local radio station with live programmes, a schedule and interviews available on demand in its app. Every recording has a title and a description. Those help listeners browse, but an interview often contains useful details that never make it into the summary.In our example, the episode is called “The city we share”. Its description introduces a conversation about everyday life in the city. During the recording, an urban planner explains the city's approach to summer heat: planting trees along school routes, adding shade to playgrounds and replacing some paved surfaces with planted areas.None of those measures appears in the title or description. A listener remembers the subject and asks:Which episode explained how the city plans to reduce summer heat?We have added audio podcasts as knowledge sources for GoodBarber Chatbot so questions like this can lead back to your programmes. There are two levels: the written information you publish about each episode, and the spoken content you choose to have transcribed.

The same approach can support learning resources, member guides, technical references or any other useful documents shared through an app. For our example, consider a colleague trying to book a client trip who needs to know:Which travel expenses need prior approval?We have added document sources to GoodBarber Chatbot so that the files you already maintain can support these conversations.
