Filechat is an AI-powered tool that utilizes artificial intelligence to facilitate document exploration. It allows users to upload diverse document formats and interact with a chatbot by posing questions. The chatbot retrieves relevant excerpts as evidence to substantiate its responses. The tool provides subscription plans that grant credits for various functionalities, including API integration. The credit system relies on token utilization, ensuring that documents are safeguarded and encrypted in cloud storage. Potential forthcoming enhancements encompass the ability to engage in multi-file conversations, share documents, and enhance citation capabilities.
