Buy once

How we counted: Copilot is sold bundled with Microsoft 365 seats; the comparison is the entry bundle per user per month. Not a like-for-like feature match — a hosted assistant inside Office versus a local agent with a ledger — the number is what a seat costs.

Why owning beats renting Microsoft 365 Copilot (bundled plans).

One payment

No monthly, per-seat or per-location fees. The license is perpetual.

Your data stays on your server

It never lives in Microsoft 365 Copilot (bundled plans)'s cloud.

No plan ceilings

Records and users are limited by your hosting, not by a pricing tier.

It keeps working if the vendor doesn't

Self-hosted software can't be sunset or repriced out from under you.

The fair trade-offs: you host it, back it up and apply updates yourself. See the product page for its limits, and the full Own Your AI (OYA) vs renting comparison.

Questions about moving off Microsoft 365 Copilot (bundled plans).

What do I need to run it?
A machine with Node.js 22+ and a local model server (llama.cpp, Ollama, LM Studio or vLLM). A 24 GB GPU runs a strong 27B model; 8–16 GB runs the smaller ones the setup recommends. Linux and macOS are the execution hosts; Windows runs it under WSL.
Does it phone home?
No. The only connection made on your behalf without asking is to the model endpoint you configure. Everything else is a tool you invoke, counted in the ledger. The report lists every host that appears in the source and its stated purpose; the tests fail if a host is unclassified.
Is a model included?
No — models are licensed by their publishers and you pick the one that fits your hardware. The setup recommends one and downloads it, verified. You can also point OYA at any OpenAI-compatible endpoint you trust; the app then labels the model REMOTE.
How is this different from a chat UI like Open WebUI or a cloud assistant?
It is a workbench with proof, not a chat window: on your instruction it plans, uses tools and acts on your files, mail, calendar and connected software — and every outside connection is counted and reportable. Cloud assistants run on the vendor's machines. OYA runs on yours and counts every outside connection.
