UseChat (now 88Agents)

UseChat redirects to 88Agents, the current name of the product. It is a chatbot and agent-building platform aimed at agencies and internal product teams rather than one-off website widgets. The pitch is deliberately unglamorous: you start with a smart chatbot that answers questions, knows your client's documentation and captures leads, and you scale the same assistant into an agent that can query databases, trigger workflows and call external APIs when the project demands it.

Model choice is a first-class feature rather than a hidden default. You can switch between OpenAI, Anthropic and Google Gemini models without changing code, which matters when you are managing cost and capability across many client accounts. Knowledge ingestion covers PDFs, Word and Markdown files, full website crawls, structured CSV/JSON datasets, YouTube videos and playlists for automatic transcript extraction, and FAQ pairs for exact-match answers. Everything is indexed and searchable from the same configuration.

Deployment is multi-channel from a single setup. The same knowledge base and personality can appear as an embeddable chat widget styled to match a client's brand, as a Slack app handling DMs and channel mentions, or as an email agent reading and replying over IMAP/SMTP on a schedule. Every conversation is logged and searchable, and contacts can be collected when you want to turn conversations into leads. Pricing starts around $29/month and scales to $399/month, with annual billing offering a discount, plus an enterprise tier.
