Use Case Recommendations
Best for: ChatFast
ChatFast builds specialised AI agents that answer from a customer's own knowledge base and deploy to any website with a single snippet. The framing is broader than support: the same agent construction is sold for sales qualification, customer service and research, on the argument that all three are the same operation — reason across a corpus, answer, and record what the visitor was actually asking about. That second half is the part the vendor emphasises as its differentiator, describing the agent as capturing intent and opportunities rather than only resolving tickets, so conversations become a demand signal instead of a cost centre. Setup is described as four steps from sources to a live agent. The vendor publishes a 94% accuracy figure against regular chatbots and, importantly for anyone evaluating on data-governance grounds, states that none of the customer's data trains a model. Pricing is metered in credits, at ten credits per user message, with storage as a second axis; agents themselves are unlimited on paid tiers, so an operator can run several narrow agents rather than one general one without paying per agent. The trial is fourteen days with no card and includes one agent, 1,000 credits and 5 MB of storage.
