Resolved without a human
A chatbot answers. An AI agent gets the job done.
Most “chatbots” only reply. They answer a question and stop. A real AI agent plans across multiple steps, pulls from your knowledge base, takes actions in your other tools, and knows when to bring in a human. The catch: the market is full of basic chatbots relabeled as “agents.” LoopReply was built for genuine agentic work, with a visual workflow engine, retrieval-grounded answers, action nodes that call your APIs, and built-in human takeover.
Why teams choose LoopReply for AI Agent Builder
Visual Workflow Engine
Drag and drop 15+ node types, including Intent Router, Knowledge Search, API Call, Conditions, and Collect Input, to give your agent real multi-step logic. Real branching logic, no code required.
Knowledge Base with RAG
Train your agent on PDFs, spreadsheets, URLs, databases, and more. Retrieval-augmented generation grounds every answer in your own content, so responses are accurate instead of made up.
Takes Action in Your Tools
This is what makes it an agent. API Call nodes and 30+ integrations let your agent do things in the same conversation: check an order, create a ticket, book a meeting, update your CRM, or trigger a workflow.
Omnichannel by Default
Build once, deploy everywhere. One agent runs across 11 channels, including Web, WhatsApp, Messenger, Instagram, Telegram, SMS, Voice, Slack, Discord, Teams, and Email, with no per-channel rebuild.
Built-in Human Takeover
Autonomy you can trust. When confidence drops or a customer asks for a person, the agent hands off to your team with full context preserved, then hands back to AI once it's resolved.
Any AI Model
Choose the best model for the job, from GPT-5, Claude Opus, Gemini 3, Llama 4, Mistral Large, and more, for maximum quality and uptime, with no lock-in to a single provider.
AI Agent Builder in 5 simple steps
Describe Your Agent
Tell LoopReply what you want your agent to do in plain language, or start from a template. It generates a working configuration in minutes, no code required.
Connect Your Knowledge
Upload documents or point the agent at your website, help center, or database. It learns your business and grounds every answer in your real content.
Design the Workflow
Use the visual builder to add intent routing, conditions, data collection, and the logic your agent needs to handle real, multi-step requests.
Connect Tools & Channels
Wire in API calls and 30+ integrations so your agent can take action, then deploy it to any of 11 channels with a single embed or connection.
Go Live & Improve
Launch your agent, watch resolution and handoff rates in analytics, and let your team step in via the shared inbox whenever a conversation needs a human.
