Your firm’s knowledge, inside the tools your team already uses.
No new platform to learn. Tellen agents plug into Microsoft Copilot and Claude — bringing your methodology, your standards, and your prior engagements into every conversation. Traceable, citable, grounded answers. Not generic AI.
Works where your people already work.
One connection. Your firm’s entire knowledge base — methodology, standards, prior engagements — available inside Copilot and Claude. Connect once via OAuth, no manual uploads.
Microsoft Copilot
For teams embedded in the Microsoft ecosystem. Tellen's agents show up inside Copilot — standards research, methodology guidance, and quality feedback as you work in Word, Excel, and Teams.
Claude Desktop
Conversational research with your firm's knowledge grounded in. Ask about a standard, reference a prior engagement, look up your methodology — the answer comes back with citations.
Claude Code
For developers building audit tooling and automation. Tellen's full agent suite available programmatically via MCP server.
Not generic AI. Your firm’s AI.
The difference between a generic AI answer and an audit-ready answer is your firm’s context. Tellen connects to your , your document storage, and your methodology — then serves it up correctly, every time.
Agents that train your staff
Your team asks questions in natural language. Tellen agents answer — grounded in your methodology and the standards. New hires learn while they work. Methodology changes are applied everywhere.
Real standards, not summaries
Tellen reads the actual codification in real-time — ASC sections, IFRS paragraphs, the full text. Every answer cites exactly where it came from, down to the paragraph.
Your knowledge, codified
Connect your system of record, SharePoint, and methodology. Tellen learns it all. Your institutional knowledge stops walking out the door when people leave.
See the difference.
