Mithrandir vs Zep
Mithrandir is one company memory, running in your own cloud, that every AI agent your people already use can ask, with each person seeing only what they can already access at work.
Zep is a memory and context API that developers build into their own AI agents, with the data sent in by their own code.

Questions
- Can I use Mithrandir and Zep together?
- Yes. Zep can keep powering the agents your developers build, while Mithrandir gives everyone in the company one memory inside the agents they already use.
- Does Mithrandir work with Copilot, Claude and ChatGPT?
- Yes. Claude, ChatGPT, Copilot, Cursor and 16 more agents ask Mithrandir directly, 20 in all. Nobody changes the tool they work in.
- Where does the data live?
- Mithrandir runs in your own cloud account on AWS, Azure or GCP, with your own model key. We never host your data, and restricted content never reaches a model. Zep is a hosted API, with deployment in your own VPC on its Enterprise plan.
- What does switching cost?
- Little. Mithrandir reads the sources your company already has, 26 of them, so nothing is migrated by hand and nobody moves to a new app. It installs in one step on AWS, Azure or GCP, and the first useful answers come back the same week. Seats are $29 per month for early customers.
