Managed Context State

Never lose a conversation. We handle chat history, session persistence, and infinite context windows automatically.

example.ts
import { Kastai } from '@kastai/sdk';

// Sessions persist automatically
const session = await kastai.session.create({
  userId: "user_123",
  ttl: "30d" // 30 day persistence
});

// Context follows the user
const response = await kastai.chat({
  session: session.id,
  message: "What did we discuss yesterday?"
});

Integrated Knowledge

Upload documents once. Query forever. Built-in vector storage and retrieval pipelines without the boilerplate.

example.ts
// Ingest your knowledge base
await kastai.memory.ingest({
  source: "./documents/",
  strategy: "semantic-chunking"
});

// Retrieve relevant context
const context = await kastai.memory.retrieve(query, {
  topK: 5,
  threshold: 0.8
});

Thought Streaming

Visualize the reasoning. Stream not just the answer, but the chain-of-thought and citations in real-time.

example.ts
// Stream with reasoning traces
for await (const chunk of response.stream()) {
  console.log(chunk.delta);     // token
  console.log(chunk.thought);   // reasoning
  console.log(chunk.citations); // sources
}

// Show users how the AI thinks
