# Trina AX > Trina AX is an open-source (Apache-2.0) hub that connects every employee's own Claude to the company's files, with per-person folder permissions, company skills and per-person usage. Trina AX is made by Trina Inc. (주식회사 트리나). Claude runs as it does today (the desktop and phone apps, claude.ai, Claude Code, Cowork); the hub serves the company's files to each person's Claude with that person's folder permissions. It is free to self-host (Apache-2.0). Trina hosts it at your-company.trina.app and offers setup and monthly operation, quoted per company. Claude usage is billed by Anthropic, not by Trina. Trina AX is not affiliated with Anthropic. ## What it does - Company files, with each person's permissions: Claude finds and reads documents in the company folders and saves its work there. Each person's Claude opens only the folders that person may open; the others don't even show up. - Reads the files you actually have: PDF, Word, Excel, PowerPoint and Korean HWP/HWPX, as text. - The same way of working on every desk: Write a skill once, like a quote template or a weekly report, and every employee's Claude has it. Change it and everyone gets the new version. - Usage per person: See who uses Claude, how much, with which model and skill, and export it as CSV. Set monthly limits for people on the company key. - A record of every file action: Who read, changed or deleted which file is recorded. Overwritten and deleted files are kept for 90 days and can be restored. - On the phone, too: The same company files in the Claude mobile app, through the same connection. ## How it starts 1. We set up your hub: At your-company.trina.app on our servers, or on a Mac mini or Linux server of yours. Files go in by upload in the browser or by copying a folder. 2. Connect your Claude organization: On Claude Team or Enterprise, your admin adds the connector and pastes the settings the hub generates. Once, for everyone. Nothing to install on each PC. 3. Invite your team: Each person gets a link, picks a password and clicks Connect in Claude. That's it. - On Pro or Max plans, each person adds the connector address once. People on the company API key connect Claude Code with one command. ## Security: what we promise, and where it stops - Every request for a file is checked against the folder rules, from every app. - The company API key stays on the hub. It never reaches a PC. - Each PC and each app connection has its own token, stored hashed and revocable at any time. - Uploaded documents are opened in a sandbox. - Logs never contain tokens, keys, passwords or file contents. - What we don't promise: what Claude reads to answer a question goes to Anthropic under your Claude plan's terms. People with administrator access to the server can read the files; on a hub we host, that includes Trina's operators. ## Pages - [Home](https://ax.trina.app/): product, pricing shape and FAQ - [Security](https://ax.trina.app/security): What Trina AX promises about your files, how each promise is kept, and where the promises stop.

No. They use the Claude they already know. We set up the hub and connect your Claude organization. Running it yourself needs a developer who has run a server before. ### Is it really free? The software is free (Apache-2.0). Only hosting, setup and operation by Trina are paid, and they are quoted. Claude usage is paid to Anthropic separately. ### Where do our files live? On the hub: on Trina's servers if we host it, or on your server or office Mac mini if you run it. File contents go to Anthropic only when Claude reads them to answer. ### Can someone see another team's folder? No. You set who can open each folder, and each person's Claude opens only those. A folder you can't open looks like it doesn't exist. ### Which Claude plan do we need? Claude Team or Enterprise is simplest: your admin sets it up once for everyone. Individual Pro and Max plans, or a company API key, work too. ### What if we stop? We hand your files back as they are, and you can keep running the same open-source software yourself. ### Does it work with ChatGPT? Not today. Trina AX works with Claude. ### Are you part of Anthropic? No. Trina AX is made by Trina Inc. (주식회사 트리나). ## Contact - contact@trina.app (calls, quotes, support); subject "Security: Trina AX" for vulnerabilities
