Overview

Cassidy, founded in 2023, builds AI assistants grounded in a specific company's own internal documents, wikis, and tools rather than general web knowledge, so answers reflect that company's actual policies, processes, and data instead of generic information an off-the-shelf chatbot would provide.

A large share of Cassidy deployments start inside Slack, where an employee can ask a question and get an answer sourced from internal documentation directly in the channel they're already working in, rather than opening a separate app. Beyond question-answering, no-code workflow building lets teams create assistants for specific recurring business processes, beyond a general internal search chatbot.

There's no free tier; pricing starts through direct signup with usage-based plans. For a company that wants employees getting accurate answers grounded in internal knowledge without leaving tools like Slack, and building custom assistants for specific business processes without engineering resources, Cassidy's no-code, internally-grounded approach targets that specific need directly.
