Sealed keeps everything you deliver to a client in one place: organised like folders, read like a website, tracked like a sales tool, and ready for your AI agent.
No client accounts. No card. Free during early access.
The handoff
Because the work is scattered. Files go out as attachments and links across five different tools, each with its own password, and you never know what was read.
In one sentence
Sealed is a private, organised room for each of your clients. You put proposals, reports, decks, PDFs and AI-made HTML pages into folders; your client opens one link, unlocks it once, and always sees what's new.
How it works
Create a room for the client, drop the work in, set one passcode, and send one link. Sealed tells you when they open it.
A name is enough. Add nested folders such as Proposals, Reports and Designs.
Upload any file or a whole folder, up to 500 MB per file. Large uploads resume if the connection drops, and you can paste HTML straight from your AI tool.
Choose a passcode, specific email addresses or a whole email domain. It covers every folder and document in the room.
The link never changes. Update a document in place and your client sees the new version at the same address.
Opens are recorded per document, without bots, link scanners or your own views. New and Updated marks show your client what changed.
Client uploads and requests will land in the folder you choose.
Built in
Every room comes with privacy by default, one set of access controls per client, live versions, and a clear record of what your client has seen.
Links are unguessable, client pages are served with noindex, known AI crawlers are blocked, and nothing is listed publicly.
Anyone with the link, a passcode, verified email addresses or a whole domain, or internal only. Add an expiry date. Unlocks are remembered on the device, for 30 days by default.
Upload a new version and the link stays the same. Every version is kept, and any of them can be restored.
See who opened what, and when. New and Updated marks show each viewer what changed since they last looked.
Ask a client for files or answers, and let them upload straight into the folder you choose.

For agents
Yes: your agent can already publish, version and file work through the Sealed REST API with an API key. MCP access for your agent, and for your client's agent, is coming soon.
Any agent or script that can make an HTTP request, such as Claude Code, Cursor, n8n or your own code, can work in your rooms with a labelled API key.
On Camp, a client contact will be able to connect their own agent, limited to their own room.
# 1. Make sure the client's folders exist (missing ones are created)

Sealed gives each client one room that you organise and they unlock once. It's private like a portal, as easy as a link, and it tells you what was read.

FAQ
Short, direct answers about Sealed: client access, privacy, agents, file types and early access.
No. Your client opens the link. If the room is protected, they enter the passcode, or a one-time code sent to their email, once, and their device remembers it.
Yes, on Camp. One passcode, or a verified email or domain, covers every folder and document in the room, including anything you add later. You can override a single folder or document, and the override is clearly marked.
No. Links are unguessable, every client page is served with noindex headers, known AI crawlers are blocked, and nothing is listed publicly.
Yes, through the REST API with an API key: publish, upload new versions, file work into folders by path, and set access. MCP support for Claude, ChatGPT, Cursor and other agents is coming soon.
Coming soon on Camp. A client contact will be able to connect their own agent over MCP, limited to their own room, to read what you shared, see what changed, and upload files.
PDFs (with a built-in viewer), HTML pages (pasted or uploaded), Markdown, images and video open in the browser. Other files, such as Office documents, are offered as downloads. Files can be up to 500 MB during early access.
Every new workspace gets 3 months of full access, free and with no card. Paid plans start after that, and you're reminded 14, 7 and 1 day before it ends. If you don't continue, your workspace becomes read-only for you, and your clients' links keep working.
Email attachments go stale, and Drive or Notion links scatter across threads, each with its own sharing settings. Page-per-link tools give each deliverable its own page and often its own passcode. Sealed gives each client one room with folders, one unlock, versions that keep the same link, and open tracking. Unlike most client portals, your client needs no account.
