What Copilot and Claude Code Can't Connect To
Both assistants reason well about data you hand them. Neither can reach the systems your operations team works in all day. Here is the list, and what does connect.
Microsoft 365 Copilot and Claude Code have no governed way to read from or write to the line-of-business systems professional services firms run on. Copilot reaches data through the Microsoft Graph, which stops at your mailbox, files, Teams, and SharePoint. Claude Code is a coding agent, so reaching anything else means writing and maintaining custom API code yourself. The blocker is reach, not intelligence.

Why the gap is where the hours live
The work that costs an operations team its week is not drafting. It is moving data between systems: opening the DMS, copying a figure into the CRM, filing the executed document, checking it by hand. An assistant that cannot reach those systems automates the easy middle and hands the integration back to a person, so the bottleneck never moves.

Caddi builds automations from a screen recording and runs them across 150+ tools as deterministic code. See real workflows for law firms and RIAs, or book a demo.

Frequently asked questions
Can Microsoft 365 Copilot connect to iManage, NetDocuments, or Aderant?
No. Copilot reaches data through the Microsoft Graph, which covers your mailbox, files, Teams, and SharePoint. Line-of-business systems like iManage, NetDocuments, Aderant, and Elite 3E sit outside that boundary, so there is no native connector that reads or writes them.
Can Claude Code connect to these systems?
Not in a governed way. Claude Code is a coding agent: reaching any of these systems means writing and maintaining custom API code yourself, where an API exists, with credentials handled outside your firm's controls.
What does connect to them?
Caddi connects to each system through a real connection, then runs the whole workflow across it as deterministic code, with scoped access and a run-by-run audit trail. Caddi is SOC 2 attested.
Why does the reach matter more than the model?
Both assistants can reason well about data you hand them. The work that costs an operations team time is moving data between systems, and that needs a connection, not a better model.
