Start from a template
New agent, start from an app: Chrome, Word, Excel, PowerPoint or Outlook. Pick the model and publish.
Agents
Fadenstack where people already work.
Assistants in Chrome and in Word, Excel, PowerPoint and Outlook. They answer with your organization's models through your Fadenstack server, follow the rules IT sets there, and ask before they change anything. They are free to use with every Fadenstack server.
Chrome
The browser agent.
A side panel in Chrome that works with the page you have open. Open it from the toolbar or with Alt+Shift+F.
Read, compare, write.
- Summarises the page, your selection or other open tabs
- Reads PDFs in the browser and opens the page a passage is on
- Copies tables and compares what two tabs say
- Writes formatted text into web editors and fills in forms
It asks first.
- In the default mode, it asks before it writes or clicks: once, or for the rest of the chat if you allow that
- It never fills in password fields or fields marked for card numbers
- You allow it site by site
- Your conversations stay in the browser; the server keeps the usage and which tools ran
What you need
Chrome 116 or later, and the address of your Fadenstack server. People sign in with their Fadenstack account.
The Chrome Web Store listing comes with the first release. IT can also install the agent for everyone by policy and preset the server address.
Word · Excel · PowerPoint · Outlook
Agents in Office.
A task pane in each app that reads your selection and the document, and works with the app's own tools. One sign-in covers all four.
Review and edit
Edits arrive as tracked changes and remarks as comments, so you accept or reject each one.
Cells, tables, charts
Reads and fills in cells and tables, and builds charts from your data.
Slides and notes
Summarises a deck, writes slides and drafts the speaker notes.
Mail and calendar
Reads the thread, drafts replies, creates appointments, and never sends anything itself.
Asks before it changes anything
Allow once, allow for this chat, or deny. IT decides which tools may run at all.
Undo in every app
Word and PowerPoint use their own Undo; Excel and Outlook have an Undo agent change button, which in Excel does not cover formatting or a deleted sheet.
Private on the computer
Chats are stored encrypted on the computer, and the sign-in is protected by Windows.
What you need
Windows with the Microsoft 365 desktop apps. For mail, the classic Outlook for Windows; the new Outlook does not run these add-ins.
The installer comes with the first release. IT can preset the server and the agents for every computer.
A desktop agent In development
The same assistant on the desktop, outside the browser and Office.
For IT
Set up once, governed on the server.
Every agent is registered on your Fadenstack server. The app on someone's computer brings the tools; the server decides who may use the agent, which model answers and what its tools may do.
Who may use it
Grant an agent to people or teams, check anyone's access, and sign out a device.
Versions that stay put
A published version never changes. Publish a new one, or roll back to an earlier one.
Tool modes and rules
Off, read only, ask or automatic, plus rules that deny or allow a tool.
New tools wait
For an agent with a tool list, a tool that arrives with an app update is held back until an admin accepts it.
One record
The agents' requests show up in usage, traces and the audit log, next to the chat's.
Build your own
Your agents, on the same SDK.
These agents are built on the open-source Fadenstack SDKs for .NET and TypeScript. Your developers get the same parts: sessions, tools that run on the user's side, approvals and a ready chat panel.
Free to use
The agents are free to use with any Fadenstack server. They are not open source; the SDKs they are built on are.
Their terms of use and privacy statement are published with the first release.
Give your people an assistant where they work.
Install the server, publish an agent from a template, and point the apps at your server.
