The platform supports rapid deployment with a one-line widget for websites, CLI tooling and a self-hostable MCP server for enterprises that want to run the stack on their own infrastructure.

Key Features

Document-based grounding

Scans, chunks and indexes PDFs and URLs so the agent answers from your docs with citations — no tagging or training data required.

Grounded & cited answers

Answers are grounded in indexed knowledge and include citations to source documents to reduce hallucinations.

Omnichannel support & single inbox

Supports multiple channels with one shared inbox showing open, pending and closed views across every channel; AI and human-handled chats coexist in the same inbox.

Human handover

One-click transfer to a human with full context; detects when a customer is frustrated or stuck and escalates accordingly.

Lead capture & qualification

Converts conversations into qualified leads by asking targeted questions at the right moment and routing leads to sales, Slack or CRM.

Auto-built help center

Builds a fully-branded, searchable help center from the same knowledge that powers the agent, with AI search that answers and cites.

No-code workflows

Drag-and-drop visual workflows to build multi-step flows with conditions, forms, messages and human handoff without engineering.

Developer tooling & self-hosting

CLI for signup, agents, knowledge and workflows; MCP server with personal access tokens; scriptable commands and self-hostable architecture.

MCP tools & API actions

Connect MCP tools so the agent can take actions mid-conversation (look up orders, issue refunds, create tickets, call your APIs).

Customizable chat widget

Multiple presets and full theming (colors, shape, typography, position) with live preview; paste a single script to go live.

Frequently Asked Questions

How fast can I go live?
Under two minutes. Sign up, point it at your docs, and paste one line of code. The agent indexes your knowledge automatically.
What happens when the AI can't answer?
It detects when a customer is stuck or frustrated and hands off to your team with full context — or handles everything itself if you prefer.
Is it really open source?
Yes. The full platform is open source — inspect it, self-host it, and bring your own models. Or use the cloud and skip the ops.

Getting Started

  1. 1 Step 1: Create your account — sign up with email and land in the dashboard (free for first 300 chats).
  2. 2 Step 2: Feed it & shape it — drop PDFs or URLs, write the agent's personality prompt, and preview answers in real time.
  3. 3 Step 3: Paste one line of code — copy the widget snippet into your site and go live in under two minutes.
