88Agents (formerly UseChat.ai) vs AI Chat Bestie

88Agents, formerly listed as UseChat.ai, is a chat bot builder for agencies that deploy customer-facing assistants across web widgets, Slack, and email. You bring your own API keys and pick models from OpenAI, Anthropic, or Google Gemini, so billing stays tied to the providers you already use. One configuration can start as a doc-trained chatbot and scale into agents that call APIs or query databases.

Most chatbot SaaS locks you to one model vendor and charges per message on top. 88Agents flips that with a bring-your-own-key setup and multi-channel deploy from a single bot config. The same knowledge base and personality can land on a site embed, a Slack workspace, or an IMAP inbox without rebuilding flows per channel.

Agency builders and technical teams use 88Agents when clients need reliable chatbots first and optional agent workflows later. Knowledge ingestion covers PDFs, site crawls, CSV datasets, YouTube transcripts, and FAQ pairs, with full conversation history for review.
