“How easy it was to deploy. We basically created client portals where I could put the chatbot directly into that portal so that a client would be able to access it while maintaining security.”

Agentic AI
Take action with your knowledge
Your agent doesn’t just answer questions. It captures leads, verifies facts, analyzes documents, and triggers actions across your entire stack.
Custom Actions
An open adapter to thousands of platforms. Connect via MCP or API to pull live data or trigger actions in any external system, no custom dev required.
Image Intelligence
Your agent sees what your documents show, not just what they say. Charts, diagrams, screenshots, and product photos are ingested and understood. Users can also upload images in chat.
Verify Every Answer
Every claim fact-checked against your source documents. Unsupported statements are flagged before they reach users, with audit-ready reports for Legal, Compliance, and Security.
Drive Conversions
Track when agent conversations lead to outcomes. Define conversion events, measure what topics drive action, and connect AI performance to business results.
Analyze Documents
Deep analysis of a single document. Target any file from your knowledge base or upload one directly in chat for cited, sourced analysis against your full database.
Capture Leads
Collects names, emails, and intent mid-conversation without friction. Qualified leads push to your CRM via Zapier, API, or CSV, with source attribution.
Webpage Awareness
Your agent knows what page a visitor is on. Tailor responses to context automatically without the user having to explain where they are or what they need.
In-Chat CTAs
Add branded buttons to any agent response. Route users where they need to go: book a call, hand off to a live agent, open a form, or surface a resource.
Live Web Search
Supplements your knowledge base with real-time web results when answers need current information.
Enterprise-Grade Security
Built for businesses that can’t afford a breach
Your data stays yours. Every agent runs in an isolated, encrypted environment with no cross-contamination.
-
Your data never trains AI
We have zero data-sharing agreements with OpenAI or any model provider. Your content is never used for training. It stays inside your agents only.
-
Encrypted. Then deleted.
All data is protected with 256-bit AES encryption and SSL in transit. Source files are purged after processing so nothing lingers on our servers.
-
Isolated per agent by design
Each agent runs in a hard data silo. There is zero cross-contamination between your agents, your customers, or anyone else’s deployment.
-
Dedicated private infrastructure
Enterprise deployments run on a dedicated private VPC on AWS US East. No shared compute, no noisy neighbors, full network isolation.
