This is a web app that generates interactive and visually appealing reports from chat exports obtained from supported platforms. The generated report contains statistics, information and interactive graphs about the chats. Privacy is paramount to this app, as all chat data stays in the device while generating reports. The following platforms are supported: Discord, Messenger, Telegram, and WhatsApp. Users can generate reports using the command line interface (CLI) with the npx chat-analytics command. Technical details and development instructions are available in the docs/README.md and docs/DEV.md files, respectively. The project acknowledges several libraries and tools that made it possible, including FastText, multilang-sentiment, Emoji sentiment data, and stopwords-iso. The AGPLv3 license governs the use of this app.
