Deploy only the pieces you need: AI-native editing, headless processing, storage, and governance, each running entirely on your own infrastructure.
Embed a full Office editor UI in your application. Use APIs to open, save, and modify documents, and connect LLMs or AI agents to object-level editing tools for the current document.
A document management backend for storage integration, versioning, permissions, metadata, search, and lifecycle operations. Connect it to S3-compatible object storage, WebDAV, or HTTP-based storage, including Amazon S3, Cloudflare R2, and MinIO.
Capture AI edits, human review, and approvals as structured evidence outside the document file. Link them to document versions, storage, sharing, and audit events.
Connect your application to Thinkfree and bring Office document capabilities into your AI workflows.
import { Office } from "@thinkfree.dev/tfo-sdk";
const iframe = document.querySelector("#office-frame");
const word = Office.word(iframe);
await word.whenReady();
const tools = await word.getTools({
include: ["insert_text"],
});
const systemPrompt = await word.getSystemPrompt();
// Pass the tools to your model loop.
