Frequently asked questions

Do I need technical knowledge to connect?

For Claude and ChatGPT, not really — you connect with an API key (starting with exa_) or via OAuth and follow our steps. No code needed. For Gemini and Copilot it's a bit more technical, via the CLI/SDK or Copilot Studio. Unsure? Start with Claude or ChatGPT.

Does it work with ChatGPT?

Yes, and it runs in production. You connect it via Connectors in ChatGPT, available on Plus, Team and Enterprise. Then you ask questions in plain language about your Exact administration and get instant answers.

Does it work with Claude?

Yes, and this is the most direct way. Claude supports our connection natively via MCP — in Claude Desktop, Claude Code and Claude on the web. You do need a paid Claude plan. Once connected, you simply talk to your books without installing anything else.

Can I connect multiple administrations?

Yes. How many depends on your plan: Free 2, Starter 3, Pro 10 and Enterprise unlimited. You can also set per administration whether writing is enabled.
