Some notes from our CFO below. Use the 2026 numbers, and can the intro be shorter?

01

A comment becomes the change. Once, in the source.

Feedback lands in the document, the sheet or the slide, not in a mail or a PDF. Tag your agent in the comment and it makes the change in the source, with the brief and the brand rules in front of it, and the file records who asked for it. Nothing is re-typed, and nothing goes out until you say so.

What you get

Every version kept

Each change is saved as its own version. Compare versions and pick the best one. Picked the wrong one? Go back to an earlier version.

Editor tools included

Document, slide and sheet editors come out of the box, next to the brief and the brand kit. No separate tool subscriptions.

Your methods, for every client

Your brand kits, templates and ways of working in one workspace, ready for any client. Edit the work, ask your agent and handle feedback without switching tools.

Questions

What is Syns Workspace?

One workspace for your team's client work: every brief, file and tool your agents work from, on the AI subscriptions you already have. The project tools are included: documents, slides and sheets. Your agent reads the workspace before it works and writes back what it did, and every change is a version.

Who is Syns for?

Teams that collaborate on client work: agencies, studios and consultancies where several people, and the client, work on the same project. Decks, reports, proposals, pages and campaigns, for teams who already use AI on client work.

My client already uses AI. What changes?

Good, that is the point. Today their AI works without your brief, so what it sends back is off-brand or ignores what you agreed, and you spend a round putting it back.

In Syns your client works in the same project as you. They comment and suggest in the work itself. Your agent checks what they bring against the brief, the brand kit and your decisions, keeps their idea, and prepares it in your style. You decide what ships.

They stay close to the work, and you keep the final say.

How do I set up Syns?

Install the Syns plugins for Claude Code with one command, once. Then open a new session in an empty folder and send the setup message from Start now. Your agent sets up your workspace, signs you in, and replies with a link to your workspace in your browser, where you chat with your agent, and every change is shared as soon as it finishes a step.

How is this different from the shared projects in my AI app?

Those live inside one AI vendor's app, so they only work for people on that vendor's plan. Your client can't join without one, and what you taught that AI stays with it.

In Syns your client opens the work in their browser and comments, no AI account needed. Your skills, templates and brand kit work for every agent on your team.

Nobody's work gets lost. If a colleague or an agent changes the work from an outdated copy, the change is stopped instead of saved over yours, and you can see who changed what and roll back. And the work stays yours: files you can take anywhere, not locked in one AI vendor's app.

How is this different from Google Drive or Notion?

You can already let Claude edit a Doc or a Sheet in Drive or Notion. But it reaches them through a connector (MCP), one call at a time, and only when it decides to look. The brief, the brand kit and your past work sit in other files it has not read.

In Syns every file is local to the agent, and the workspace is organised for an AI to read. It knows where the skills, examples and templates are, and applies them in the right template, formatting and tone, faster. No connector, no round trips: the files are simply there.

How fast do I see my changes?

As soon as an agent finishes a step, its changes are shared with everyone on the project, and every new session starts from the latest version. And the AI works best when the files are local: it edits them on your machine, burns fewer tokens, and gets you the right result faster.

Does my client need Claude?

No. They view and comment in the browser. Your agent prepares the change and you approve it. Your client uploads nothing; the context is already there.

Can a client break my work?

No. Your client comments and picks between versions, but you accept the changes. Every change is a version with a name on it, and an edit made on an old copy is refused instead of overwriting yours.

Which tools are inside?

Documents, slides and sheets, built into the workspace next to the brief and the brand kit, so your agent and your client work on the same project. We are adding more tools. Missing one? Tell us at [email protected].

Do I have to leave my AI subscription?

No. Syns runs on top of the subscription you already pay for. Claude is supported today; ChatGPT is coming soon.

Is my data private?

Every project is private by design. Syns Workspace is a hosted service. To anyone without access, a private project is indistinguishable from one that does not exist. Your data stays yours at all times: it is never reused, never trained on, never shared and never sold.
