Your agents' cloud documents.
Reports, plans and write-ups your agents make become docs with a short private link. People you work with open them after signing in, download them, or turn them into a Tunc Art file. Sign up free, create an API key and connect your agents, or use it through Tunc Hub.
Built into Tunc Hub. Open to every agent.
Use Tunc Doc through Tunc Hub, or sign up and connect any agent with an API key. One Tunc account and one free 1 GB pool cover Tunc Doc, Tunc Art, Tunc Orb and Tunc Hub.

Knowing the link isn't enough.
Every doc stays private to the people who have access to it.
- Docs
- Markdown text of up to 1 MiB, with a title. Each doc has a short private link such as tuncdoc.com/x7Kp2a.
- Viewers
- Every visit is checked. People sign in with their Tunc account; a doc opens for its owner and for the people with access to the workspace it was made in.
- Links
- A link alone never opens a doc, and a doc you cannot open looks the same as a link that does not exist.
- Edits
- Agents change exact text, and all of an edit applies or none of it does. A rewrite starts from the revision the agent read, so newer changes are kept.
- Writing together
- People who may change a doc switch to Write on its page. Everyone writing sees the others’ changes as they happen, and an agent’s small edits appear the same way. A large change from an agent is saved at once and shows for people writing after their next save, or when they open the doc again. Writing works in a browser on a computer; on a phone a doc opens to read.
- Formats
- Agents export a doc as DOCX, PDF, Markdown or HTML. People download it from its page.
- Save to Tunc Art
- Turn a doc into a Tunc Art file with its own private link.
- Storage
- 1 GB free, shared by Tunc Hub, Tunc Art, Tunc Doc and Tunc Orb across one Tunc account.
Part of one system.

Asked often.
- What is Tunc Doc?
- Tunc Doc is where your agents write documents. Agents create, read and edit Markdown docs, and each doc gets a short private link. People open it after signing in, and the people who may change it can write in it too; a link alone never opens it.
- Who can open a Tunc Doc link?
- The owner, and the people with access to the workspace a doc was made in, after signing in with their Tunc account. A doc made without a workspace is private to its owner. Anyone else gets the same page as for a link that does not exist.
- Can people write in a doc too?
- People who may change a doc open it on tuncdoc.com and switch to Write. Everyone writing sees the others’ changes as they happen, and an agent’s small edits appear the same way. A large change from an agent is saved at once and shows for people writing after their next save, or when they open the doc again. Someone who can only read gets Read. Writing works in a browser on a computer; on a phone a doc opens to read.
- How does an agent write a doc?
- Over MCP at https://mcp.tuncdoc.com/mcp (doc_create, doc_list, doc_read, doc_edit, doc_write, doc_export and doc_delete), over A2A at https://a2a.tuncdoc.com/v1, or with the REST API at https://api.tuncdoc.com/v1/docs. Creating a doc returns its link. In Tunc Hub the doc tools are built in, and a doc opens in the Preview tab.
- Which file formats can I get a doc in?
- Agents can export a doc as DOCX, PDF, Markdown or HTML. People download a doc from its page, and can turn it into a Tunc Art file that has its own private link.
- How do I get started?
- Sign in at tunchub.com with Google, Apple or Microsoft, name your organization and accept the Terms. Then create an API key, or let your agent sign in itself. It is free.
- How much does Tunc Doc cost?
- Free to start: 1 GB of storage shared by Tunc Hub, Tunc Art, Tunc Doc and Tunc Orb. Docs are stored in it. Add 10 GB for $4.99 a month (sold through Link in 82 countries).
- How big can a doc be?
- A doc is Markdown text of up to 1 MiB.
- How do I stop an agent?
- Disconnect it, or narrow it to read-only, on tunchub.com under Agents & keys. A disconnected agent is refused within a minute; your other agents keep working.
Give every document your agents write a home.
Free: 1 GB, shared with Tunc Hub, Tunc Art and Tunc Orb.
