Now Available

The enterprise SDK for building AI-native interfaces. Stream Claude's intelligence directly into your product with structured annotations, tool transparency, and human-in-the-loop controls.

What makes ABI Chat different

Real-time Streaming

Server-Sent Events deliver tokens as they're generated. Your users see responses forming in real-time — no waiting for completion.

🧩

Structured Annotations

Rich context panels — charts, tables, diffs, progress trackers, and dashboards — appear alongside the conversation automatically.

🔄

Multi-turn Context

Full conversation history is maintained across turns. ABI remembers context, builds on previous answers, and stays coherent.

🔧

Tool Integration

Watch Claude think with tool calls. Every tool invocation and result is surfaced in the UI with full transparency.

🛡️

Human-in-the-Loop

Approval gates let users review and authorize actions before they execute. Full control without breaking the flow.

🌐

Edge-Native

Runs on Cloudflare Workers, Vercel Edge, or any standard runtime. No Node.js servers required — deploy globally in seconds.

How it works

01

Connect

Point the SDK at your API endpoint. One line of configuration — your API key stays server-side.

02

Stream

Send a message. The SDK opens an SSE connection and begins streaming tokens, tool calls, and annotations in real-time.

03

Render

Tokens flow into the chat. Structured annotations populate the context panel. Tool calls are surfaced with full transparency.

04

Iterate

Multi-turn context keeps the conversation coherent. Each turn builds on the last — just like talking to a colleague.
