Questions & Answers

As answered by people managing agent4.io and Chatbase.

Who are some of the biggest customers of your product?

agent4.io's answer

Law firms and legal consultancies Immigration and study-abroad agencies Insurance brokers and lending firms

Which are the primary technologies used for building your product?

agent4.io's answer

Python / FastAPI backend with PostgreSQL Retrieval-augmented generation (RAG) with vector search for grounded answers Model Context Protocol (MCP) + Skills for agent-native building and integrations Next.js web front-end and an embeddable chat widget An OpenAI-compatible model gateway (works across leading LLMs, e.g. Claude) Channel integrations for website, Telegram and WhatsApp REST API + webhooks for white-label and custom apps

What's the story behind your product?

agent4.io's answer

agent4.io started from a pattern we kept seeing: businesses that sell expertise — law firms, brokers, schools, agencies — spending expensive human time answering the same questions over and over, while the enquiries nobody got to were simply lost. The "AI chatbots" they tried either made things up or forgot the customer the moment the chat closed. So we built the opposite: an agent that only speaks from your own material, remembers each customer across every channel, and follows up on its own. As AI coding assistants took off, we made the whole platform agent-native too, so builders can stand up a grounded agent over MCP + Skills in minutes. The goal is simple — let a reliable agent handle the routine work, around the clock, for a fraction of the cost.

How would you describe the primary audience of your product?

agent4.io's answer

Businesses that sell expertise and field the same questions all day, where an accurate, always-on agent pays for itself. Core verticals: legal, immigration, insurance, lending, study-abroad and education, hospitality, and SaaS/software. The buyer is usually a founder, a marketing or operations lead, or whoever is drowning in inbound enquiries. Two builder profiles use it: non-technical teams who work in the no-code dashboard, and developers and AI builders who wire it up agent-native over MCP + Skills or the REST API.

Why should a person choose your product over its competitors?

agent4.io's answer

Most chatbot builders answer from a scraped FAQ and forget you between messages. agent4.io is grounded, remembers, and follows up:

Grounded, not guessing — replies come from your own knowledge base, so answers stay accurate and on-brand. Per-customer memory across web, Telegram and WhatsApp — one agent, one customer history. Follows up on schedule — it re-engages leads instead of waiting to be asked. Agent-native — build over MCP + Skills from your coding assistant, or white-label the API for a custom app; you're not locked into a single no-code UI. Unlimited agents on every plan, including a free tier. It's for teams that need an agent to actually do the routine work — answer, qualify, follow up — not just a widget that deflects tickets.

What makes your product unique?

agent4.io's answer

agent4.io is built for one job general chatbots aren't: agents that consult, convert, and follow up for businesses that sell expertise. Three things set it apart. First, answers are grounded in your own knowledge base — the agent replies from your documents, never the open internet, so it doesn't invent facts about your business. Second, per-customer memory: every agent remembers each customer across conversations and across channels — website, Telegram and WhatsApp. Third, it's agent-native — you can build and run knowledge bases, skills and agents entirely over MCP + Skills from a coding assistant like Claude Code or Cursor, not only a dashboard. On top of that, Storylines let an agent run stateful, multi-step processes, and scheduled follow-ups mean it re-engages leads instead of answering once and going quiet.

    Chatbase Evaluation: Definitely, after many hours of uploading documents that I have been refining, it continues to respond with absurd or incorrect answers, and sometimes even claims to have no information when it...
