AgentiveAIQ
Best for: Law firms that need a fully branded, no‑code AI chatbot for client intake, legal research, and course tutoring, with optional e‑commerce and integration capabilities.
AgentiveAIQ has positioned itself as a no‑code, enterprise‑grade AI platform that empowers law firms to create fully branded virtual assistants without writing a single line of code. At the core of the platform is a two‑agent architecture: the main chat agent engages clients in real‑time conversations, while an assistant agent runs in the background, parsing those interactions and generating actionable insights that can be delivered to attorneys via email. What sets AgentiveAIQ apart is its WYSIWYG chat widget editor, which lets legal teams design a floating or embedded chat window that matches their firm’s brand colors, fonts, and logo—perfect for maintaining a professional look on a law firm’s website. The platform also supports a dual knowledge base that combines Retrieval‑Augmented Generation (RAG) for fast fact extraction from uploaded documents with a knowledge graph that understands relationships between legal concepts, enabling nuanced, context‑aware responses. For firms that offer online courses or webinars, the hosted AI page feature provides secure, password‑protected portals where clients can access AI‑driven tutoring. Importantly, AgentiveAIQ’s long‑term memory is only enabled for authenticated users on these hosted pages, ensuring that private client data is retained across sessions while anonymous widget visitors experience session‑based memory. With plans starting at $39/month for two chat agents and 2,500 messages, the Pro tier ($129/month) unlocks eight agents, 25,000 messages, a million‑character knowledge base, and no branding.
