Dropchat

Dropchat is a custom chatbot builder that runs on your own data. Rather than a general assistant, you point it at something specific: a book identified by ISBN, author, or title, a file such as a PDF, a YouTube video, or a website, and it builds a chat interface over that material. You can also create a fully custom bot from scratch if none of the preset source types match what you need. The site says the tool can be tried for free without logging in or providing credit card details, which lowers the barrier to testing whether it fits your use case before you commit to an account.

- Chat with a book using only its ISBN, author, or title

- Chat with content from PDFs, YouTube videos, and websites

- Build a custom chatbot around your own material

- Test the whole flow before creating an account

- Ask questions in plain language instead of searching for keywords

- Readers and researchers who want to question a specific book

- People who would rather converse with their files than search them

- Teams that need a simple bot over a website or knowledge base

- Students working through a long document or a recorded lecture

The bot can only reflect the material you give it, so thin or poorly structured sources produce thin answers, and a summary of a book will not contain details that were never in the source in the first place. Free use without an account may come with limits on length, number of chats, or features, and those rules can change without notice. Long documents and videos also take time to process, so patience helps on the first run. The answers should be checked against the original source before you rely on them for anything important, since a confident tone is not the same thing as an accurate answer.
